安卓通知

android studio sdk 升级到23后 setLatestEventInfo被完全弃用api11 之前的机型可以使用v4包下的NotificationCompat实现

 1 import android.support.v4.app.NotificationCompat;
 2 NotificationManager mManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
 3 
 4 NotificationCompat.Builder notifyBuilder;
 5 
 6 Intent resultIntent = new Intent(this, MainActivity.class);
 7 resultIntent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
 8 
 9 PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, resultIntent, PendingIntent.FLAG_UPDATE_CURRENT);
10 
11 Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.icon);
12 notifyBuilder = new NotificationCompat.Builder(this)
13         .setLargeIcon(bitmap)/*设置large icon*/
14         .setSmallIcon(R.drawable.icon)/*设置small icon*/
15         .setContentTitle("通知")/*设置title*/
16         .setContentText("有新的通知")/*设置详细文本*/
17         .setWhen(System.currentTimeMillis())/*设置发出通知的时间为发出通知时的系统时间*/
18         .setTicker("有新的通知")/*设置发出通知时在status bar进行提醒*/
19         .setOngoing(true)/*setOngoing(boolean)设为true,notification将无法通过左右滑动的方式清除 * 可用于添加常驻通知，必须调用cancle方法来清除 */
20         .setAutoCancel(true)/*设置点击后通知消失*/
21         .setNumber(2)/*设置通知数量的显示类似于QQ那种，用于通知的合并*/
22         .setContentIntent(pendingIntent);/*点击跳转到MainActivity*/
23 mManager.notify(0, notifyBuilder.build());
