消息提示--Notification实践

消息通知比较常见，主要是用NotificationCompat的一些接口来进行内容设置，有点像AlertDialog的创建，主要是他们的封装都用了Builder；下面给出两段创建和清除消息提示的代码片段。

新建一个消息提示：

public void openNotification() {        NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this).setSmallIcon(R.drawable.action_share)                .setContentTitle("Notification Title").setContentText("Hello World!").setNumber(5).setSubText("this is sub content")                .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher));        Intent resultIntent = new Intent(this, MainActivity.class);        TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);        stackBuilder.addParentStack(MainActivity.class);        stackBuilder.addNextIntent(resultIntent);        PendingIntent resultPendingIntent = stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);        mBuilder.setContentIntent(resultPendingIntent);        notificationManager.notify("test", 0, mBuilder.build());    }

关闭消息：

    public void cancelNotification() {        notificationManager.cancelAll();    }
