DrawerLayout实现侧滑菜单效果

众所周知，android里面我们很熟悉的一个功能，侧滑菜单效果在以前我们大部分都是用的slidingmenu这个开源框架，自从谷歌官方新出的一个DrawerLayout控件之后，越来越多的应用开始使用谷歌的官方的控件写这个效果了。

话不多说，先来发图以表我滴诚意：

开始写代码

DrawerLayout 是v4包里面的，所以项目里面需要添加v4包，具体怎么添加就不多说了，
NavigationView需要在build.gradle里面添加compile ‘com.android.support:design:25.1.0’

---

activity_main.xml

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

    
    <include
        layout="@layout/app_bar_main"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    
    <android.support.design.widget.NavigationView
        android:id="@+id/nav_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:fitsSystemWindows="true"
        app:headerLayout="@layout/nav_header_main"
        app:menu="@menu/activity_main_drawer" />

android.support.v4.widget.DrawerLayout>

然后在res文件夹里面添加一个menu菜单文件夹，已经添加的就不用添加了

上面的代码里面NavigationView里面有个 app:menu=”@menu/activity_main_drawer”对应如下:
添加一个菜单文件，名字随意，我的是activity_main_drawer.xml
activity_main_drawer.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android">

    <group android:checkableBehavior="single">
        <item
            android:id="@+id/nav_camera"
            android:icon="@drawable/ic_menu_camera"
            android:title="第一行" />
        <item
            android:id="@+id/nav_gallery"
            android:icon="@drawable/ic_menu_gallery"
            android:title="第二行" />
        <item
            android:id="@+id/nav_slideshow"
            android:icon="@drawable/ic_menu_slideshow"
            android:title="第三行" />
        <item
            android:id="@+id/nav_manage"
            android:icon="@drawable/ic_menu_manage"
            android:title="第四行" />
    group>

    <item android:title="Communicate">
        <menu>
            <item
                android:id="@+id/nav_share"
                android:icon="@drawable/ic_menu_share"
                android:title="第五行" />
            <item
                android:id="@+id/nav_send"
                android:icon="@drawable/ic_menu_send"
                android:title="第六行" />
        menu>
    item>

menu>

再添加一个布局

上面的代码里面app:headerLayout=”@layout/nav_header_main”对应如下:
添加一个布局，名字是nav_header_main.xml
nav_header_main.xml

<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="@dimen/nav_header_height"
    android:background="@drawable/side_nav_bar"
    android:gravity="bottom"
    android:orientation="vertical"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:theme="@style/ThemeOverlay.AppCompat.Dark">

    <ImageView
        android:id="@+id/imageView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:paddingTop="@dimen/nav_header_vertical_spacing"
        app:srcCompat="@android:drawable/sym_def_app_icon" />

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:paddingTop="@dimen/nav_header_vertical_spacing"
        android:text="哈哈哈"
        android:textAppearance="@style/TextAppearance.AppCompat.Body1" />

    <TextView
        android:id="@+id/textView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="[email protected]" />

LinearLayout>

MainActivity：

public class MainActivity extends BaseActivity  implements NavigationView.OnNavigationItemSelectedListener {

    private LinearLayout right;
    private NavigationView left;
    private boolean isDrawer=false;
    private DrawerLayout drawer;



    @Override
    public int getLayoutId() {
        return R.layout.activity_main;
    }

    @Override
    public void initPresenter() {

    }

    @Override
    public void initView() {
        drawer = (DrawerLayout) findViewById(R.id.drawer_layout);


        right = (LinearLayout) findViewById(R.id.right);
        left = (NavigationView) findViewById(R.id.nav_view);

        NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
        navigationView.setNavigationItemSelectedListener(this);

        right.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View view, MotionEvent motionEvent) {
                if(isDrawer){
                    return left.dispatchTouchEvent(motionEvent);
                }else{
                    return false;
                }
            }
        });
        drawer.setDrawerListener(new DrawerLayout.DrawerListener() {
            @Override
            public void onDrawerSlide(View drawerView, float slideOffset) {
                isDrawer=true;
                //获取屏幕的宽高
                WindowManager manager = (WindowManager) getSystemService(Context.WINDOW_SERVICE);
                Display display = manager.getDefaultDisplay();
             //设置右面的布局位置  根据左面菜单的right作为右面布局的left   左面的right+屏幕的宽度（或者right的宽度这里是相等的）为右面布局的right
                right.layout(left.getRight(), 0, left.getRight() + display.getWidth(), display.getHeight());
            }
            @Override
            public void onDrawerOpened(View drawerView) {}
            @Override
            public void onDrawerClosed(View drawerView) {
                isDrawer=false;
            }
            @Override
            public void onDrawerStateChanged(int newState) {}
        });


    }



    @Override
    public void onBackPressed() {
        if (drawer.isDrawerOpen(GravityCompat.START)) {
            drawer.closeDrawer(GravityCompat.START);
        } else {
            super.onBackPressed();
        }
    }




    @SuppressWarnings("StatementWithEmptyBody")
    @Override
    public boolean onNavigationItemSelected(MenuItem item) {
        // Handle navigation view item clicks here.
        int id = item.getItemId();

        if (id == R.id.nav_camera) {
            // Handle the camera action
        } else if (id == R.id.nav_gallery) {

        } else if (id == R.id.nav_slideshow) {

        } else if (id == R.id.nav_manage) {

        } else if (id == R.id.nav_share) {

        } else if (id == R.id.nav_send) {

        }

        DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
        drawer.closeDrawer(GravityCompat.START);
        return true;
    }

drawer.openDrawer(GravityCompat.START);//打开滑动菜单

drawer.closeDrawer(GravityCompat.START);//关闭滑动菜单

drawer.isDrawerOpen(GravityCompat.START);//判断滑动菜单是否打开
