如何在應用程序收到fcm通知時顯示自定義頂部/底部視圖

Question

我在應用程序收到fcm通知時顯示自定義視圖有困難。 我成功地顯示收到的fcm通知給android的通知列表。 但我也希望fcm消息作爲自定義視圖顯示在屏幕上（自上而下，幾秒鐘後消失），而不管應用狀態如前景，背景或死亡。

我該如何解決我的問題？ 先進的謝謝！

我猜你需要實現PopupWindow有在this doc

我要展示一個樣品的情況下，這樣你可以瞭解一個簡短的想法。

假設你對你的View的layout是custom_layout.xml

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/rl_custom_layout" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:padding="2dp" 
    android:background="#ab2fc4" 
> 
    <ImageButton 
     android:id="@+id/ib_close" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:src="@drawable/ic_close_white_24dp" 
     android:layout_alignParentEnd="true" 
     android:layout_alignParentRight="true" 
     android:background="@null" 
    /> 
    <TextView 
     android:id="@+id/tv" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="This is a sample popup window." 
     android:layout_centerInParent="true" 
     android:padding="25sp" 
    /> 
</RelativeLayout> 

然後在你要處理的雲消息，你只需要添加此代碼段

LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(LAYOUT_INFLATER_SERVICE); 

      // Inflate the custom layout/view 
      View customView = inflater.inflate(R.layout.custom_layout,null); 


      // Initialize a new instance of popup window 
      mPopupWindow = new PopupWindow(
        customView, 
        LayoutParams.WRAP_CONTENT, 
        LayoutParams.WRAP_CONTENT 
      ); 

      // Set an elevation value for popup window 
      // Call requires API level 21 
      if(Build.VERSION.SDK_INT>=21){ 
       mPopupWindow.setElevation(5.0f); 
      } 

      // Get a reference for the custom view close button 
      ImageButton closeButton = (ImageButton) customView.findViewById(R.id.ib_close); 

      // Set a click listener for the popup window close button 
      closeButton.setOnClickListener(new View.OnClickListener() { 
       @Override 
       public void onClick(View view) { 
        // Dismiss the popup window 
        mPopupWindow.dismiss(); 
       } 
      }); 

在這種情況下，你可以點擊關閉您的mPopupWindow。如果您想自動關閉它，請使用Handler使用其postDelayed()方法。 要知道如何實現其與Handler看到這個answer

希望這有助於我得到的幫助！

您可以使用下面的代碼，使自定義視圖：

Notification notification = new Notification(icon, "Custom Notification", when); 

     NotificationManager mNotificationManager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE); 

     RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.custom_notification); 
     contentView.setImageViewResource(R.id.image, R.drawable.ic_launcher); 
     contentView.setTextViewText(R.id.title, "Custom notification"); 
     contentView.setTextViewText(R.id.text, "This is a custom layout"); 
     notification.contentView = contentView; 

     Intent notificationIntent = new Intent(this, MainActivity.class); 
     PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0); 
     notification.contentIntent = contentIntent; 

     notification.flags |= Notification.FLAG_NO_CLEAR; //Do not clear the notification 
     notification.defaults |= Notification.DEFAULT_LIGHTS; // LED 
     notification.defaults |= Notification.DEFAULT_VIBRATE; //Vibration 
     notification.defaults |= Notification.DEFAULT_SOUND; // Sound 

     mNotificationManager.notify(1, notification);
