通知Notification

簡單Notification

• 創建Builder

NotificationCompat.Builder mBuilder =
        new NotificationCompat.Builder(this)
                .setSmallIcon(R.mipmap.ic_launcher)
                .setContentTitle("My notification")
                .setContentText("Hello World!");

• 添加Active

// 2. 創建點擊回調動作
Intent resultIntent = new Intent(this, ResultActivity.class);
// Because clicking the notification opens a new ("special") activity, there's
// no need to create an artificial back stack.
PendingIntent resultPendingIntent =
        PendingIntent.getActivity(
                this,
                0,
                resultIntent,
                PendingIntent.FLAG_UPDATE_CURRENT
        );
mBuilder.setContentIntent(resultPendingIntent);

• 通知

// Builds the notification and issues it.
mNotifyMgr.notify(101, mBuilder.build());

• 後臺調用

// Creates an Intent for the Activity
Intent resultIntent = new Intent(this, ResultActivity.class);
// Sets the Activity to start in a new, empty task
resultIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK |
        Intent.FLAG_ACTIVITY_CLEAR_TASK);
// Creates the PendingIntent
notifyIntent = PendingIntent.getActivity(
        this,
        0,
        resultIntent,
        PendingIntent.FLAG_UPDATE_CURRENT
);

移除Notification

1. 調用後自動清除

builder.setAutoCancel(true);

1. 指定的 notification ID調用了cancel()
2. 指定的 notification ID調用了cancelAll()

接下來的幾個樣式就不說了，簡單，先貼圖再看代碼

BigView之Text

• 調用bigTextNotification
  

BigView之Picture

• 調用bigPictureNotification
  

BigView之Inbox

• 調用bigInboxNotification
  

BigView之Custom

• 調用customNotification
  
  • 大圖
    
  • 小圖
