Notification用法复习(3.0以后版本)
使用Notification的示例代码：
public class Main extends Activity implements OnClickListener {private NotificationManager notificationManager;private Notification.Builder mBuilder;private Notification mNotification;private void showNotification(String tickerText, String contentTitle,String contentText, int smallIconId, int bigIconId) {// 如果同类型消息还显示在通知栏，则仅更新消息条数.if (mBuilder != null && mNotification != null) {RemoteViews contentView = mNotification.contentView;contentView.setTextViewText(R.id.fileName, contentText);mBuilder.setContentTitle(contentTitle);mBuilder.setTicker(tickerText);mBuilder.setWhen(System.currentTimeMillis());// mBuilder.setContentInfo("提示消息");// mBuilder.setContentText(contentText);notificationManager.notify(1, mBuilder.getNotification());return;}Intent notificationIntent = new Intent(this, Main.class);// 如果当前Activity启动在前台，则不开启新的Activity。notificationIntent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);PendingIntent contentIntent = PendingIntent.getActivity(this, 0,notificationIntent, 0);mBuilder = new Notification.Builder(this);// 设置下拉列表里的标题mBuilder.setContentTitle(contentTitle);// mBuilder.setContentInfo("提示消息");// mBuilder.setContentText(contentText);// 自定义显示消息内容RemoteViews contentView = new RemoteViews(getPackageName(),R.layout.inbox);contentView.setTextViewText(R.id.fileName, contentText);// 指定个性化视图mBuilder.setContent(contentView);mBuilder.setContentIntent(contentIntent);// mBuilder.setDeleteIntent(contentIntent);// 设置状态栏里面的图标（小图标） mBuilder.setSmallIcon(smallIconId);// 下拉下拉列表里面的图标（大图标)mBuilder.setLargeIcon(BitmapFactory.decodeResource(getResources(),R.drawable.smile));// 状态栏显示的标题文本.mBuilder.setTicker(tickerText);mBuilder.setDefaults(Notification.DEFAULT_SOUND);// 设置事件发生时间mBuilder.setWhen(System.currentTimeMillis());// Setting this flag will make it so the notification is automatically// canceled when the user clicks it in the panel.mBuilder.setAutoCancel(true);mNotification = mBuilder.getNotification();notificationManager.notify(1, mNotification);}int i = 0;int j = 0;@Overridepublic void onClick(View v) {switch (v.getId()) {case R.id.btnSmile:showNotification("您收到的消息数：" + (++i) + "条！", "消息数", "您收到的消息数："+ (++j) + "条！", R.drawable.why, R.drawable.smile);break;}}@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);// 实例化NotificationManager.notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);Button btnSmile = (Button) findViewById(R.id.btnSmile);btnSmile.setOnClickListener(this);}@Overrideprotected void onNewIntent(Intent intent) {super.onNewIntent(intent);System.out.println("onNewIntent() method called!!!");i = 0;j = 0;}}<activity android:name=".Main" android:label="@string/app_name" android:launchMode="singleTop" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity>
