Notification用法

本文介绍了Notification的用法。

1、示例演示用法

1)NotificationActivity.java

/** * 演示了Notification的用法 * Notification的创建、显示、删除 * 通知栏点击Notification打开Activity、Service、Broadcast * 直接new一个Notification或通过Notification.Builder来创建 * 自定义Notification的视图并点击交互 */public class NotificationActivity extends Activity {private BroadcastReceiver mBroadcastReceiver;private NotificationManager mNotificationManager;private int NOTIFICATION_ID = 0x007;private int NOTIFICATION_ID2 = 0x008;private int NOTIFICATION_ID3 = 0x009;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);init();}private void init(){IntentFilter intentFilter = new IntentFilter();intentFilter.addAction(NewBroadcastReceiver.ACTION_NOTIFICATION);intentFilter.addAction(NewBroadcastReceiver.ACTION_NOTIFICATION2);mBroadcastReceiver = new NewBroadcastReceiver();registerReceiver(mBroadcastReceiver, intentFilter);mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);findViewById(R.id.btn).setOnClickListener(mOnClickListener);findViewById(R.id.btn_direct).setOnClickListener(mOnClickListener);findViewById(R.id.btn_custom).setOnClickListener(mOnClickListener);//API level 11Notification.Builder builder = new Notification.Builder(this);builder.setSmallIcon(R.drawable.ic_launcher)//status bar.setTicker("猥琐不")//status bar.setWhen(System.currentTimeMillis())//the time the event occurred.setDefaults(Notification.DEFAULT_SOUND).setContentTitle("石鑫").setContentText("小李飞刀").setContentInfo("美好的回忆").setContentIntent(PendingIntent.getActivity(this, 0, new Intent(this, NewActivity.class), 0))//startActivity//.setContentIntent(PendingIntent.getBroadcast(this, 0, //new Intent(NewBroadcastReceiver.ACTION_NOTIFICATION), 0))//sendBroadcastReceiver//.setContentIntent(PendingIntent.getService(this, 0, //new Intent(this, NewService.class), 0))//startService.setAutoCancel(true);//dismiss when touchedNotification notification = builder.getNotification();//v16用buildmNotificationManager.notify(NOTIFICATION_ID, notification);}@Overrideprotected void onDestroy() {super.onDestroy();unregisterReceiver(mBroadcastReceiver);}private OnClickListener mOnClickListener = new OnClickListener() {@SuppressWarnings("deprecation")@Overridepublic void onClick(View v) {switch (v.getId()) {case R.id.btn:mNotificationManager.cancel(NOTIFICATION_ID);//通过ID删除NotificationmNotificationManager.cancel(NOTIFICATION_ID2);mNotificationManager.cancel(NOTIFICATION_ID3);break;case R.id.btn_direct:Notification notification = new Notification(R.drawable.ic_launcher, "monkey", System.currentTimeMillis());//给Notification添加soundUri ringURI = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);notification.sound = ringURI;//给Notification添加Vibrationlong[] vibrate = new long[]{1000,1000,1000,1000,1000};notification.vibrate = vibrate;notification.setLatestEventInfo(NotificationActivity.this, "Activity", "launch an activity", PendingIntent.getActivity(NotificationActivity.this, 0, new Intent(NotificationActivity.this, NewActivity.class), 0));mNotificationManager.notify(NOTIFICATION_ID2, notification);break;case R.id.btn_custom:Notification notification2 = new Notification(R.drawable.ic_launcher, "monkey", System.currentTimeMillis());RemoteViews remoteView = new RemoteViews(getPackageName(), R.layout.notification);notification2.contentView = remoteView;notification2.contentIntent = PendingIntent.getActivity(NotificationActivity.this, 0, new Intent(NotificationActivity.this, NewActivity.class), 0);notification2.contentView.setTextViewText(R.id.txt, "骚包");notification2.contentView.setProgressBar(R.id.progressbar, 1000, 400, false);//注册及在广播中处理点击事件notification2.contentView.setOnClickPendingIntent(R.id.img, PendingIntent.getBroadcast(NotificationActivity.this, 0, new Intent(NewBroadcastReceiver.ACTION_NOTIFICATION2), 0));mNotificationManager.notify(NOTIFICATION_ID3, notification2);default:break;}}};}

2)activity_main.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical" >    <Button         android:id="@+id/btn"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="hit me"        android:layout_gravity="center"/>    <Button         android:id="@+id/btn_direct"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="direct"        android:layout_gravity="center"/>    <Button         android:id="@+id/btn_custom"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="custom"        android:layout_gravity="center"/></LinearLayout>

3)NewActivity.java

public class NewActivity extends Activity {@Overrideprotected void onCreate(Bundle savedInstanceState) {Log.i(getClass().getSimpleName(), "onCreate");super.onCreate(savedInstanceState);setContentView(R.layout.activity_new);}}

4)activity_new.xml

<?xml version="1.0" encoding="utf-8"?><RelativeLayout    android:layout_width="match_parent"    android:layout_height="match_parent"    xmlns:android="http://schemas.android.com/apk/res/android">    <TextView         android:layout_width="match_parent"        android:layout_height="wrap_content"        android:text="欢迎步入星光大道"/></RelativeLayout>

5)NewBroadcastReceiver.java

public class NewBroadcastReceiver extends BroadcastReceiver {/**使用4次，定义、注册、发送、接收*/public static final String ACTION_NOTIFICATION = "action.NOTIFICATION";public static final String ACTION_NOTIFICATION2 = "action.NOTIFICATION2";@Overridepublic void onReceive(Context context, Intent intent) {if(ACTION_NOTIFICATION.equals(intent.getAction())){Log.i(getClass().getSimpleName(), "onReceive");}else if(ACTION_NOTIFICATION2.equals(intent.getAction())){Toast.makeText(context, "轻点好吗", Toast.LENGTH_SHORT).show();}}}

6)NewService.java

public class NewService extends Service {@Overridepublic IBinder onBind(Intent intent) {//只有Service.onBind(Intent)覆写return null;}@Overridepublic void onCreate() {Log.i(getClass().getSimpleName(), "onCreate");super.onCreate();}@Overridepublic int onStartCommand(Intent intent, int flags, int startId) {Log.i(getClass().getSimpleName(), "onStartCommand");return super.onStartCommand(intent, flags, startId);}}

7)notification.xml

<?xml version="1.0" encoding="utf-8"?><RelativeLayout    android:layout_width="match_parent"    android:layout_height="match_parent"    xmlns:android="http://schemas.android.com/apk/res/android">    <ImageView         android:id="@+id/img"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_centerVertical="true"        android:layout_alignParentLeft="true"        android:src="@drawable/ic_launcher"/>    <TextView         android:id="@+id/txt"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_centerHorizontal="true"        android:layout_alignParentTop="true"/>    <ProgressBar         android:id="@+id/progressbar"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:layout_toRightOf="@id/img"        android:layout_alignParentBottom="true"        style="@android:style/Widget.ProgressBar.Horizontal"/></RelativeLayout>

8)AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="com.qinuli.notificationtest"    android:versionCode="1"    android:versionName="1.0" >    <uses-sdk        android:minSdkVersion="11"        android:targetSdkVersion="19" />    <uses-permission android:name="android.permission.VIBRATE"/>        <application        android:allowBackup="true"        android:icon="@drawable/ic_launcher"        android:label="@string/app_name"        android:theme="@style/AppTheme" >        <activity            android:name="com.qinuli.notificationtest.NotificationActivity"            android:label="@string/app_name" >            <intent-filter>                <action android:name="android.intent.action.MAIN" />                <category android:name="android.intent.category.LAUNCHER" />            </intent-filter>        </activity>        <activity android:name=".NewActivity"></activity>        <service android:name=".NewService"/>    </application></manifest>
