1、AppBarLayout、ToolBar

AppBarLayout 是继承LinerLayout实现的一个ViewGroup容器组件,它是为了Material Design设计的App Bar,支持手势滑动操作。
AppBarLayout必须作为Toolbar的父布局容器,也可以配合CoordinatorLayout一起使用。
ToolBar是谷歌新推出的代替ActionBar的一个标题栏控件,能将背景拓展到状态栏,依赖包是v7,使用之前先把style中继承的主题改为NoActionBar;
可以设置”标题”,”副标题”,”Logo”,”NavigationIcon”以及”Menu菜单”,也可以自定义布局;

.support.design.widget.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

    .support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="70dp"
        android:minHeight="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        app:layout_collapseMode="pin"
        app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
        android:fitsSystemWindows="true"
        >
        "@+id/toolbar_title"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginLeft="0dp"
            android:layout_marginStart="0dp"
            android:gravity="center"
            android:text="@string/app_name"
            android:textColor="#FFFFFF"
            android:textSize="20sp"
            android:paddingTop="6dp"
            android:paddingRight="40dp"
            />
    .support.v7.widget.Toolbar>
.support.design.widget.AppBarLayout>

TextView是一个居中的标题,
fitsSystemWindows实现状态栏各版本适配方案:
1.Android5.0以上:material design风格,半透明(APP 的内容不被上拉到状态)
2.Android4.4(kitkat)以上至5.0:全透明(APP 的内容不被上拉到状态)
3.Android4.4(kitkat)以下:不占据status bar
在Activity中添加代码即可使用ToolBar;

        mToolbar = (Toolbar) findViewById(R.id.toolbar);
        tvToolTitle = (TextView) findViewById(R.id.toolbar_title);
        tvToolTitle.setText("测试");
        setSupportActionBar(mToolbar);
        getSupportActionBar().setDisplayShowTitleEnabled(false);

这里写图片描述

ToolBar中的菜单布局:

<menu xmlns:android="http://schemas.android.com/apk/res/android"  
    xmlns:app="http://schemas.android.com/apk/res-auto"  
    xmlns:tools="http://schemas.android.com/tools"  
    tools:context=".MainActivity" >   
    <item  
        android:id="@+id/action_settings"  
        android:orderInCategory="100"  
        android:title="action_settings"  
        app:showAsAction="never"/>  

menu>  
mToolbar.setOnMenuItemClickListener(new Toolbar.OnMenuItemClickListener() {  
    @Override  
    public boolean onMenuItemClick(MenuItem item) {  
        switch (item.getItemId()) {  
        case R.id.action_settings:  
            break;  
        default:  
            break;  
        }  
        return true;  
    }  
});  

2、DrawerLayout、NavigationView

DrawerLayout可以轻松的实现抽屉效果、在DrawerLayout中,第一个子View必须是显示内容的view,第二个view是抽屉view,设置属性layout_gravity=”left|right”,表示是从左边滑出还是右边滑出。
使用前需添加:

compile 'com.android.support:design:23.3.0'

xml中的布局代码如下:

"http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">


    .support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

        .support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="70dp"
            android:minHeight="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            app:layout_collapseMode="pin"
            app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
            android:fitsSystemWindows="true"
            >
            "@+id/toolbar_title"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_marginLeft="0dp"
                android:layout_marginStart="0dp"
                android:gravity="center"
                android:text="@string/app_name"
                android:textColor="#FFFFFF"
                android:textSize="20sp"
                android:paddingTop="6dp"
                android:paddingRight="40dp"
                />
        .support.v7.widget.Toolbar>
    .support.design.widget.AppBarLayout>


    .support.v4.widget.DrawerLayout
        android:id="@+id/drawer_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fitsSystemWindows="true">

        
        .support.design.widget.CoordinatorLayout
            android:id="@+id/main_content"
            android:layout_width="match_parent"
            android:layout_height="match_parent">

            "@+id/frame_content"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:layout_below="@+id/appbar"
                android:scrollbars="none"
                app:layout_behavior="@string/appbar_scrolling_view_behavior" />
        .support.design.widget.CoordinatorLayout>


        
        .support.design.widget.NavigationView
            android:id="@+id/navigation_view"
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:layout_gravity="start"
            app:headerLayout="@layout/navigation_header"
            app:menu="@menu/drawer" />

    .support.v4.widget.DrawerLayout>

第一个布局使用的是Framelayout,可以通过侧滑抽屉栏的点击显示出不同的Fragment;
而抽屉布局用的是NavigationView,NavigationView需要接收几个必要的参数、一个用于显示头部的布局以及用于显示选项的菜单布局;可在xml中直接添加布局;

     app:headerLayout="@layout/navigation_header"
     app:menu="@menu/drawer"

头部布局xml代码:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="192dp"
    android:background="?attr/colorPrimaryDark"
    android:gravity="center"
    android:orientation="vertical"
    android:padding="16dp"
    android:theme="@style/ThemeOverlay.AppCompat.Dark">


    <de.hdodenhof.circleimageview.CircleImageView
        android:id="@+id/profile_image"
        android:layout_width="72dp"
        android:layout_height="72dp"
        android:layout_marginTop="20dp"
        android:src="@mipmap/ic_launcher"
        app:border_color="@color/primary_light"
        app:border_width="2dp" />


    <TextView
        android:layout_marginTop="10dp"
        android:textSize="18sp"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="测试账号"
        android:gravity="center"
        android:textAppearance="@style/TextAppearance.AppCompat.Body1"
         />

LinearLayout>

选项菜单布局:

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    tools:context=".MainActivity">
    <group android:checkableBehavior="single">
        <item
            android:id="@+id/navigation_item_book"
            android:icon="@mipmap/ic_stars_black_24dp"
            android:title="测试" />
        <item
            android:id="@+id/navigation_item_example"
            android:icon="@mipmap/ic_brightness_7_black_24dp"
            android:title="测试" />
        <item
            android:id="@+id/navigation_item_blog"
            android:icon="@mipmap/ic_flare_black_24dp"
            android:title="测试" />

        <item
            android:id="@+id/navigation_item_about"
            android:icon="@drawable/ic_favorite"
            android:title="测试" />
    group>
menu>

配合ToolBar,在Activity中的使用代码:

public class MainActivity extends AppCompatActivity implements BackHandledFragment.BackHandlerInterface {

    private DrawerLayout mDrawerLayout;
    private ActionBarDrawerToggle mDrawerToggle;
    private Toolbar mToolbar;
    private BackHandledFragment selectedFragment;
    private NavigationView mNavigationView;
    private TextView tvToolTitle;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mToolbar = (Toolbar) findViewById(R.id.toolbar);
        tvToolTitle = (TextView) findViewById(R.id.toolbar_title);
        setSupportActionBar(mToolbar);
        getSupportActionBar().setDisplayShowTitleEnabled(false);
        mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
        mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, mToolbar, R.string.drawer_open,
                R.string.drawer_close);
        mDrawerToggle.syncState();
        mDrawerLayout.addDrawerListener(mDrawerToggle);
        mNavigationView = (NavigationView) findViewById(R.id.navigation_view);
        setupDrawerContent(mNavigationView);
        switchToBook();

    }


    private void switchToBook() {
        getSupportFragmentManager().beginTransaction().replace(R.id.frame_content, new RecyclerFragment()).commit();
        tvToolTitle.setText("测试");
    }

    private void switchToExample() {
        getSupportFragmentManager().beginTransaction().replace(R.id.frame_content, new DayFragment()).commit();
        tvToolTitle.setText("测试");
    }

    private void switchToBlog() {
        getSupportFragmentManager().beginTransaction().replace(R.id.frame_content, new BlankFragment()).commit();
        tvToolTitle.setText("测试");
    }

    private void switchToAbout() {
        getSupportFragmentManager().beginTransaction().replace(R.id.frame_content, new TimeFragment()).commit();
        tvToolTitle.setText("测试");
    }


    private void setupDrawerContent(NavigationView navigationView) {
        navigationView.setNavigationItemSelectedListener(
                new NavigationView.OnNavigationItemSelectedListener() {
                    @Override
                    public boolean onNavigationItemSelected(MenuItem menuItem) {
                        switch (menuItem.getItemId()) {

                            case R.id.navigation_item_book:
                                switchToBook();
                                break;
                            case R.id.navigation_item_example:
                                switchToExample();
                                break;
                            case R.id.navigation_item_blog:
                                switchToBlog();
                                break;
                            case R.id.navigation_item_about:
                                switchToAbout();
                                break;

                        }
                        menuItem.setChecked(true);
                        mDrawerLayout.closeDrawers();
                        return true;
                    }
                });
    }



    @Override
    public void setSelectedFragment(BackHandledFragment backHandledFragment) {
        this.selectedFragment = backHandledFragment;
    }


    private long exitTime = 0;

    public void doExitApp() {
        if ((System.currentTimeMillis() - exitTime) > 2000) {
            Toast.makeText(this, R.string.press_again_exit_app, Toast.LENGTH_SHORT).show();
            exitTime = System.currentTimeMillis();
        } else {
            finish();
        }
    }

    @Override
    public void onBackPressed() {
        if (selectedFragment == null || !selectedFragment.onBackPressed()) {
            if (mDrawerLayout.isDrawerOpen(Gravity.LEFT)) {
                mDrawerLayout.closeDrawer(Gravity.LEFT);
            } else {
                doExitApp();
            }
        }
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.test,menu);
        return true;
    }
}

3、RecyclerView、CardView、AutoScrollViewPager


RecyclerView是用于显示大量数据的控件,有点类似与ListView、GirdView,相较而言,RecyclerView在灵活性、体验感上都有一个较大的提升,通过设置它提供的不同LayoutManager,ItemDecoration , ItemAnimator可以实现丰富的功能,依赖包是v7;
RecyclerView也能像ListView一样添加Header以及Footer,也可以通过addOnScrollListener进行分页加载;
以Recyclerview添加Viewpager为Header为例子对Recyclerview进行简单的使用,Viewpager使用的是GitHub上的一个开源项目,实现自动轮播的AutoScrollViewPager;
GitHub地址为:

https://github.com/Trinea/android-auto-scroll-view-pager

Header是通过GitHub上的一个开源项目RecyclerViewHeader,快速为Recyclerview添加Header;
GitHub地址为:

https://github.com/blipinsk/RecyclerViewHeader

添加完依赖包之后即可进行应用。
fragment_recyclerview.xml的代码:

"1.0" encoding="utf-8"?>
"http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    >
    .support.v7.widget.RecyclerView
        android:id="@+id/recyclerView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scrollbars="none"
        android:layout_gravity="center_horizontal|top"
        android:layout_marginBottom="20dp"
        />

    <com.bartoszlipinski.recyclerviewheader.RecyclerViewHeader
        android:id="@+id/header"
        android:layout_width="match_parent"
        android:layout_height="180dp"
        android:layout_gravity="center_horizontal|top"
        android:layout_marginBottom="20dp"
        >

        .trinea.android.view.autoscrollviewpager.AutoScrollViewPager
            android:id="@+id/vp_books"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_centerInParent="true"
            />
    com.bartoszlipinski.recyclerviewheader.RecyclerViewHeader>

recyclerview_item的代码:


<android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="170dp"
    android:layout_margin="5dp"
    android:clickable="true"
    app:cardCornerRadius="4dp"
    app:cardElevation="10dp">
        <ImageView
            android:id="@+id/ivBook"
            android:transitionName="@string/transition_book_img"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
             />
android.support.v7.widget.CardView>

RecyclerAdapter.class的代码

public class RecyclerAdapter extends RecyclerView.Adapter {

    private List list = new ArrayList<>();
    private static final int ANIMATED_ITEMS_COUNT = 4;
    private Activity context;
    private boolean animateItems = false;
    private int lastAnimatedPosition = -1;

    public RecyclerAdapter(Activity context , List mlist) {
        TypedValue mTypedValue = new TypedValue();
        context.getTheme().resolveAttribute(R.attr.selectableItemBackground, mTypedValue, true);
        list = updateItems(mlist,true);
        this.context = context;
    }


    public class ViewHolder extends RecyclerView.ViewHolder {
        public ImageView ivBook;
        public int position;

        public ViewHolder(View v) {
            super(v);
            ivBook = (ImageView) v.findViewById(R.id.ivBook);
        }
    }


    private void runEnterAnimation(View view, int position) {
        if (!animateItems || position >= ANIMATED_ITEMS_COUNT - 1) {
            return;
        }

        if (position > lastAnimatedPosition) {
            lastAnimatedPosition = position;
            view.setTranslationY(Utils.getScreenHeight(context));
            view.animate()
                    .translationY(0)
                    .setStartDelay(100 * position)
                    .setInterpolator(new DecelerateInterpolator(3.f))
                    .setDuration(700)
                    .start();
        }
    }

    public List updateItems(List books, boolean animated) {
        List list = new ArrayList<>();
        animateItems = animated;
        lastAnimatedPosition = -1;
        list.addAll(books);
        notifyDataSetChanged();
        return list;
    }


    @Override
    public RecyclerAdapter.ViewHolder onCreateViewHolder(ViewGroup parent,
                                                         int viewType) {
        View v = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.recyclerview_item, parent, false);
        ViewHolder vh = new ViewHolder(v);
        return vh;
    }

    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        runEnterAnimation(holder.itemView, position);
        RecyclerBean recyclerBean = list.get(position);
        holder.ivBook.setBackgroundResource(recyclerBean.getImg());
    }

    @Override
    public int getItemCount() {
        return list.size();
    }


    public RecyclerBean getBook(int pos) {
        return list.get(pos);
    }


    public RecyclerItemClickListener.OnItemClickListener onItemClickListener = new RecyclerItemClickListener.OnItemClickListener() {
        @Override
        public void onItemClick(View view, int position) {
            RecyclerBean book = getBook(position);
            Intent intent = new Intent(context, RecyclerDetailActivity.class);
            intent.putExtra("book", book);

            ActivityOptionsCompat options =
                    ActivityOptionsCompat.makeSceneTransitionAnimation(context,
                            view.findViewById(R.id.ivBook),context.getString(R.string.transition_book_img));
            ActivityCompat.startActivity(context, intent, options.toBundle());

        }
    };
}

RecyclerVpAdapter.class的代码:

public class RecyclerVpAdapter extends FragmentPagerAdapter {

   ArrayList list;
   FragmentManager fm;

   public RecyclerVpAdapter(FragmentManager fm, ArrayList list) {
      super(fm);
      this.list = list;
      this.fm = fm;

   }

   @Override
   public int getCount() {
      return list.size();
   }

   @Override
   public Fragment getItem(int arg0) {
      return list.get(arg0);
   }

}

RecyclerFragment.class中代码:

RecyclerView mRecyclerView = (RecyclerView) view.findViewById(R.id.recyclerView);
        mRecyclerView.setHasFixedSize(true);
        //ListView形式的列表
//        LinearLayoutManager layoutManager = new LinearLayoutManager(getActivity());
        //GirdView形式的列表
        GridLayoutManager layoutManager = new GridLayoutManager(getContext(),2);
        mRecyclerView.setLayoutManager(layoutManager);
        RecyclerViewHeader header = (RecyclerViewHeader) view.findViewById(R.id.header);
        AutoScrollViewPager viewPager = (AutoScrollViewPager) header.findViewById(R.id.vp_books);
        ArrayList fragmentList = new ArrayList<>();
        for (int i = 0; i < vpImgPath.length; i++) {
            RecyclerVpFragment recyclerVpFragment = RecyclerVpFragment.newInstance(vpImgPath[i]);
            fragmentList.add(recyclerVpFragment);
        }
        RecyclerVpAdapter bAdapter = new RecyclerVpAdapter(getChildFragmentManager(),fragmentList);
        viewPager.setAdapter(bAdapter);
        viewPager.setCurrentItem(0);
        viewPager.startAutoScroll();
        //开启Viewpager的自动轮播
        header.attachTo(mRecyclerView,true);
        for (int i = 0; i < title.length; i++) {
            RecyclerBean recyclerBean = new RecyclerBean();
            recyclerBean.setImg(imgPath[i]);
            recyclerBean.setInfo(tvInfo[i]);
            recyclerBean.setTitle(title[i]);
            recyclerBean.setCatalog(title[i]);
            recyclerBean.setAuthor_intro(title[i]);
            recyclerBean.setSummary(title[i]);
            recyclerBean.setImglarge(imgPath[i]);
            mList.add(recyclerBean);
        }
        mAdapter = new RecyclerAdapter(getActivity(),mList);
        //RecyclerView子项的点击事件
        mRecyclerView.addOnItemTouchListener(new RecyclerItemClickListener(getActivity(), mAdapter.onItemClickListener));
        mRecyclerView.setAdapter(mAdapter);

上面RecyclerView的item布局里面,父布局是一个CardView;
CardView继承FrameLayout,是能在自身之上添加了圆角和阴影效果的一种布局,常常用在RecyclerView、ListView、GirdView的item布局里面;
比较常用的有这几个属性:


 app:cardCornerRadius="4dp"
 
 app:cardElevation="10dp"

 android:foreground="?android:attr/selectableItemBackground"

4、CoordinatorLayout、CollapsingToolbarLayout、TabLayout

(GIF太大,压缩大小之后,有点儿问题)

CoordinatorLayout,一个从另一层面去控制子view之间触摸事件的布局,在CoordinatorLayout的布局中使用了Toolbar ,允许你更加自由的自定义其外观与布局的其余部分融为一体。使用AppBarLayout可以让你的Toolbar与其他View(比如TabLayout的选项卡)能响应被标记了ScrollingViewBehavior的View的滚动事件。
CollapsingToolbarLayout,可伸缩折叠的Toolbar ,直接添加Toolbar到AppBarLayout可以让你使用enterAlwaysCollapsed和 exitUntilCollapsedscroll标志,但是无法控制不同元素如何响应collapsing的细节。这里使用了 CollapsingToolbarLayout的app:layout_collapseMode=”pin”来确保Toolbar在view折叠的时候仍然被固定在屏幕的顶部当你让CollapsingToolbarLayout和Toolbar在一起使用的时候,title 会在展开的时候自动变得大些,而在折叠的时候让字体过渡到默认值。
TabLayout 既实现了固定的选项卡(View的宽度平均分配),也实现了可滚动的选项卡(View宽度不固定同时可以横向滚动)。如果你使用ViewPager在 tab之间横向切换,你可以直接从PagerAdapter的getPageTitle() 中创建选项卡,然后使用setupWithViewPager()将两者联系在一起。它可以使tab的选中事件能更新ViewPager,同时 ViewPager
的页面改变能更新tab的选中状态。
注:图中Activity的启动效果动画是通过下面代码实现的:

       ActivityOptionsCompat options =
       ActivityOptionsCompat.makeSceneTransitionAnimation(context,
       view.findViewById(R.id.ivBook),context.getString(R.string.transition_book_img));
       ActivityCompat.startActivity(context, intent, options.toBundle());

使用之前先添加Design的包,即可使用这三个;

        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

5、TextInputLayout

12个Material Design风格控件的使用_第1张图片
TextInputLayout 控件表现得就像LinearLayout 一样,它是一个容器。TextInputLayout 中只能放一个子元素,和ScrollView有点类似,并且子元素必须是EditText;
TextInputLayout 实现的功能就是当EditText中输入第一个字母要隐藏hint的时候,TextInputLayout中会出现一个悬浮的标签来显示这个hint,还负责一个炫酷的的material 动画
布局代码:


<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <include layout="@layout/include_toolbar" />

    <android.support.design.widget.TextInputLayout
        android:id="@+id/textInputEmail"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="20dp">

        <EditText
            android:id="@+id/edit_text_email"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="@string/hint_username"
            android:inputType="textEmailAddress" />
    android.support.design.widget.TextInputLayout>

    <android.support.design.widget.TextInputLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <EditText
            android:id="@+id/edit_text_password"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="@string/hint_password"
            android:inputType="textEmailAddress" />
    android.support.design.widget.TextInputLayout>
    <Button
        android:id="@+id/btnLogin"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/button_login" />

    private View view;


    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        view = inflater.inflate(R.layout.fragment_blank, container, false);
        final CoordinatorLayout coordinatorLayout = (CoordinatorLayout) view.findViewById(R.id.coordinatorLayout);
        FloatingActionButton floatingActionButton = (FloatingActionButton) view.findViewById(R.id.flb_black);
        floatingActionButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Snackbar.make(coordinatorLayout,
                        "Snackbar", Snackbar.LENGTH_LONG)
                        .setAction("OK", new View.OnClickListener() {
                            @Override

                                        getActivity(),
                                        "snackbar OK clicked",
                                        Toast.LENGTH_LONG).show();
                            }
                        })
                        .show();
            }
        });

        return view;
    }
