Android5.X切换动画
分别看下ActivityA和ActivityB的布局文件，注意transitionName在哪个View：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:orientation="vertical"
android:layout_height="match_parent">
<Button
android:layout_width="match_parent"
android:layout_height="100dp"
android:onClick="explode"
android:text="explode" />
<Button
android:layout_width="match_parent"
android:layout_height="100dp"
android:onClick="slide"
android:text="slide" />
<Button
android:layout_width="match_parent"
android:layout_height="100dp"
android:onClick="fade"
android:text="fade" />
<Button
android:layout_width="match_parent"
android:layout_height="100dp"
android:transitionName="share"
android:onClick="share"
android:text="share" />
<Button
android:id="@+id/fab_button"
android:layout_width="56dp"
android:transitionName="fab"
android:layout_height="56dp"
android:background="@drawable/ripple_round"
android:elevation="5dp"/>
LinearLayout><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin">
<View
android:id="@+id/holder_view"
android:layout_width="match_parent"
android:layout_height="300dp"
android:transitionName="share"
android:background="?android:colorPrimary" />
<Button xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/fab_button"
android:transitionName="fab"
android:layout_width="56dp"
android:layout_height="56dp"
android:layout_marginRight="@dimen/activity_horizontal_margin"
android:background="@drawable/ripple_round"
android:elevation="5dp"
android:layout_below="@+id/holder_view"
android:layout_marginTop="-26dp"
android:layout_alignParentEnd="true" />
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingTop="10dp"
android:layout_below="@id/holder_view">
<Button
android:layout_width="match_parent"
android:layout_height="60dp"

<Button
android:layout_width="match_parent"
android:layout_height="60dp"
android:layout_marginTop="10dp"
android:id="@+id/button4"
android:layout_alignParentStart="true" />
RelativeLayout>
RelativeLayout>分别看下ActivityA和ActivityB的Activity文件：
public class TransitionsA extends Activity {
private Intent intent;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_transition);
}
// 设置不同动画效果
public void explode(View view) {
intent = new Intent(this, TransitionsB.class);
intent.putExtra("flag", 0);
startActivity(intent,
ActivityOptions.makeSceneTransitionAnimation(this)
.toBundle());
}
// 设置不同动画效果
public void slide(View view) {
intent = new Intent(this, TransitionsB.class);
intent.putExtra("flag", 1);
startActivity(intent,
ActivityOptions.makeSceneTransitionAnimation(this)
.toBundle());
}
// 设置不同动画效果
public void fade(View view) {
intent = new Intent(this, TransitionsB.class);
intent.putExtra("flag", 2);
startActivity(intent,
ActivityOptions.makeSceneTransitionAnimation(this)
.toBundle());
}
// 设置不同动画效果
public void share(View view) {
View fab = findViewById(R.id.fab_button);
intent = new Intent(this, TransitionsB.class);
intent.putExtra("flag", 3);
// 创建单个共享元素
// startActivity(intent,
// ActivityOptions.makeSceneTransitionAnimation(
// this, view, "share").toBundle());
startActivity(intent,
ActivityOptions.makeSceneTransitionAnimation(
this,
// 创建多个共享元素
Pair.create(view, "share"),
Pair.create(fab, "fab")).toBundle());
}
}public class TransitionsB extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().requestFeature(Window.FEATURE_CONTENT_TRANSITIONS);
int flag = getIntent().getExtras().getInt("flag");
// 设置不同的动画效果
switch (flag) {
case 0:
getWindow().setEnterTransition(new Explode());
break;
case 1:
getWindow().setEnterTransition(new Slide());
break;
case 2:
getWindow().setEnterTransition(new Fade());
getWindow().setExitTransition(new Fade());
break;
case 3:
break;
}
setContentView(R.layout.activity_transition_to);
}
}效果图：
Toolbar的使用
记得先将主题设置为NoActionBar主题，在布局中声明ToolBar：
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize" />在Menu文件夹中创建一个Menu的XML文件：
<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/ab_search"
android:orderInCategory="80"
android:title="action_search"
app:actionViewClass="android.support.v7.widget.SearchView"
app:showAsAction="ifRoom"/>
<item
android:id="@+id/action_share"
android:orderInCategory="90"
android:title="action_share"
app:actionProviderClass="android.support.v7.widget.ShareActionProvider"
app:showAsAction="ifRoom"/>
<item
android:id="@+id/action_settings"
android:orderInCategory="100"
android:title="action_settings"
app:showAsAction="never"/>
menu>在代码中使用：
public class ToolbarActivity extends AppCompatActivity {
private ShareActionProvider mShareActionProvider;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_toolbar);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
toolbar.setLogo(R.mipmap.ic_launcher);
toolbar.setTitle("主标题");
toolbar.setSubtitle("副标题");
setSupportActionBar(toolbar);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_main, menu);
return super.onCreateOptionsMenu(menu);
}
}效果图：
修改一下布局，实现Toolbar侧滑菜单：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="com.handsome.qunyingzhuang.chapter_12.Anli02.ToolbarActivity">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize" />
<android.support.v4.widget.DrawerLayout
android:id="@+id/drawer"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@android:color/holo_blue_light"
android:orientation="vertical">
<Button
android:layout_width="100dp"
android:layout_height="match_parent"
android:text="内容界面" />
LinearLayout>
<LinearLayout
android:id="@+id/drawer_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="start"
android:orientation="vertical">
<Button
android:layout_width="200dp"
android:layout_height="match_parent"
android:text="菜单界面" />
LinearLayout>
android.support.v4.widget.DrawerLayout>
LinearLayout>在主代码中实现：
public class ToolbarActivity extends AppCompatActivity {
private ShareActionProvider mShareActionProvider;
private DrawerLayout mDrawerLayout;
private ActionBarDrawerToggle mDrawerToggle;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_toolbar);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
toolbar.setLogo(R.mipmap.ic_launcher);
toolbar.setTitle("主标题");
toolbar.setSubtitle("副标题");
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer);
mDrawerToggle = new ActionBarDrawerToggle(
this, mDrawerLayout, toolbar,
R.string.abc_action_bar_home_description,
R.string.abc_action_bar_home_description_format);
mDrawerToggle.syncState();
mDrawerLayout.setDrawerListener(mDrawerToggle);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_main, menu);
/* ShareActionProvider配置 */
mShareActionProvider = (ShareActionProvider) MenuItemCompat.getActionProvider(menu
.findItem(R.id.action_share));
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/*");
mShareActionProvider.setShareIntent(intent);
return super.onCreateOptionsMenu(menu);
}
}效果图：
基本的Notification
代码：
public class Notification01 extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_notification01);
//第一步：初始化
Notification.Builder builder = new Notification.Builder(this);
//第二步：构建点击之后的意图
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.baidu.com"));
//构造pendingdintent
PendingIntent pendingIntent = PendingIntent.getActivities(this, 0, new Intent[]{intent}, 0);
//第三步：设置通知栏的各种消息
builder.setSmallIcon(R.mipmap.ic_launcher);
builder.setContentIntent(pendingIntent);
builder.setAutoCancel(true);
builder.setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher));
builder.setContentText("Title");
builder.setContentText("内容");
builder.setSubText("text");
//第四步：通过NotificationManager来发出
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
notificationManager.notify(0, builder.build());
}
}效果图：
折叠的Notification
代码：
public class Notification02 extends AppCompatActivity {
private static final int NOTIFICATION_ID_COLLAPSE = 0x01;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_notification02);
Intent intent = new Intent(Intent.ACTION_VIEW,
Uri.parse("http://www.sina.com"));
PendingIntent pendingIntent = PendingIntent.getActivity(
this, 0, intent, 0);
Notification.Builder builder = new Notification.Builder(this);
builder.setSmallIcon(R.mipmap.ic_launcher);
builder.setContentIntent(pendingIntent);
builder.setAutoCancel(true);
builder.setLargeIcon(BitmapFactory.decodeResource(
getResources(), R.mipmap.ic_launcher));
// 通过RemoteViews来创建自定义的Notification视图
RemoteViews contentView =
new RemoteViews(getPackageName(),
R.layout.notification);
contentView.setTextViewText(R.id.textView,
"show me when collapsed");
Notification notification = builder.build();
notification.contentView = contentView;
// 通过RemoteViews来创建自定义的Notification视图
RemoteViews expandedView =
new RemoteViews(getPackageName(),
R.layout.notification_expanded);
notification.bigContentView = expandedView;
NotificationManager nm = (NotificationManager)
getSystemService(NOTIFICATION_SERVICE);
nm.notify(NOTIFICATION_ID_COLLAPSE, notification);
}
}效果图：
悬挂式Notification
代码：
public class Notification03 extends AppCompatActivity {
private static final int NOTIFICATION_ID_HEADSUP = 0x01;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_notification03);
Notification.Builder builder = new Notification.Builder(this)
.setSmallIcon(R.mipmap.ic_launcher)
.setPriority(Notification.PRIORITY_DEFAULT)
.setCategory(Notification.CATEGORY_MESSAGE)
.setContentTitle("Headsup Notification")
.setContentText("I am a Headsup notification.");
Intent push = new Intent();
push.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
push.setClass(this, MainActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(
this, 0, push, PendingIntent.FLAG_CANCEL_CURRENT);
builder.setContentText("Heads-Up Notification on Android 5.0")
.setFullScreenIntent(pendingIntent, true);
NotificationManager nm = (NotificationManager)
getSystemService(NOTIFICATION_SERVICE);
nm.notify(NOTIFICATION_ID_HEADSUP, builder.build());
}
