我已經使用RemoteViews小部件實現了自定義通知。我在Android 5.0.2和Android 6.0上進行了測試。它工作正常。但過了一段時間,它每次收到來自GCM的通知就開始崩潰。android.app.RemoteServiceException:從包中發佈的錯誤通知。無法展開RemoteViews:StatusBarNotification

崩潰轉儲 -

我爲RemoteViews佈局具有的ImageView內的LinearLayout和正在擴大的TextView定製的TextView類。

我創建通知代碼是

private void showCustomNotification(ABCNotification notification) { 
     RemoteViews notificationView = new RemoteViews(getPackageName(), R.layout.layout_notification); 
     PendingIntent contentPendingIntent = PendingIntent.getBroadcast(mContext, 0, notification.getContentIntent(), PendingIntent.FLAG_UPDATE_CURRENT); 

       NotificationCompat.Builder builder = new NotificationCompat.Builder(mContext); 
       builder.setSmallIcon(R.drawable.ic_notification).setAutoCancel(true).setContentIntent(contentPendingIntent); 

       // Set Notification Priority 
       builder.setPriority(notification.getNotificationPriority()); 

       // Set Notification Category 
       builder.setCategory(notification.getNotificationCategory()); 

       // Set Notification Visibility 
       builder.setVisibility(notification.getNotificationVisibility()); 

notificationView.setTextViewText(R.id.tv_notification_title, notification.getTitle()); 
     notificationView.setTextViewText(R.id.tv_notification_message, notification.getMessage()); 
     notificationView.setTextViewText(R.id.tv_notification_subtext, notification.getSubtext()); 
     Notification notif = builder.build(); 
       if (null != notif) { 
        if (Build.VERSION.SDK_INT > Build.VERSION_CODES.ICE_CREAM_SANDWICH_MR1) { 
         notif.bigContentView = notificationView; 
        } 
        notif.contentView = notificationView; 
        NotificationManager notificationManager = (NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE); 
        notificationManager.notify(mNotificationId, notif); 
       } 
    } 

我爲RemoteViews佈局是這樣的

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:orientation="vertical"> 

     <LinearLayout 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content" 
      android:orientation="vertical" 
      android:paddingBottom="4dp" 
      android:paddingTop="4dp"> 

      <com.abc.ui.customviews.fonts.TextViewYMRegular 
       android:id="@+id/tv_notification_title" 
       android:layout_width="match_parent" 
       android:layout_height="wrap_content" 
       android:layout_marginBottom="8dp" 
       android:ellipsize="end" 
       android:singleLine="true" 
       android:textColor="@color/black" 
       android:textSize="16sp" /> 

      <com.abc.ui.customviews.fonts.TextViewYMMedium 
       android:id="@+id/tv_notification_message" 
       android:layout_width="match_parent" 
       android:layout_height="wrap_content" 
       android:layout_marginBottom="8dp" 
       android:textColor="@color/black" 
       android:textSize="14sp" /> 

      <com.abc.ui.customviews.fonts.TextViewYMMedium 
       android:id="@+id/tv_notification_subtext" 
       android:layout_width="match_parent" 
       android:layout_height="wrap_content" 
       android:textColor="@color/black" 
       android:textSize="12sp" /> 
     </LinearLayout> 

</LinearLayout> 

我看到幾乎所有堆棧溢出的解決方案。似乎沒有任何工作。

有趣的是,它之前工作完美。但在某段時間後開始崩潰。全部在2小時內。

您無法爲'RemoteViews'使用自定義'View's。你只能使用這些類[在這裏列出](https://developer.android.com/guide/topics/appwidgets/index.html#CreatingLayout)。請注意它說「這些類的後代不支持」。 –

謝謝邁克。看來自定義的TextViews是個問題。現在它是固定的。 :-) –

正如Mike所評論的,即使它們是本地視圖的直接後代,我們也不能使用自定義視圖。

我正在使用擴展TextView的TextViewYMRegular。我將所有自定義TextView更改爲本地。

我們只能在RemoteViews中使用類listed here
