錯誤通知約束佈局

我正在使用RemoteViews顯示通知。當我使用ConstraintLayout時，會發生通貨膨脹錯誤。當我用RelativeLayout替換ConstraintLayout時，則錯誤得到解決。
爲什麼ConstraintLayout不會膨脹？錯誤通知約束佈局

我在運行時遇到以下錯誤。

錯誤

我送通知的形式服務。

NotificationManager mNotificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE); 
NotificationChannel channel = new NotificationChannel("dataSync_channel","DataSync Notification Channel",NotificationManager.IMPORTANCE_HIGH); 
     channel.setDescription("DataSync unsynchronized data status"); 
     channel.setVibrationPattern(new long[] {100,200,300,400}); 
     channel.enableLights(false); 
     channel.enableVibration(true); 
mNotificationManager.createNotificationChannel(channel); 

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this,channelId) 
       .setContentTitle("DataSync Status") 
       .setSmallIcon(android.R.mipmap.sym_def_app_icon); 

int assignmentCount=0; 
int screenCount=0; 
int attachmentCount=0; 
int fieldCount=0; 

RemoteViews remoteViews = new RemoteViews(getPackageName(), R.layout.notification_unsync_data); 
remoteViews.setTextViewText(R.id.text_assignment_count,assignmentCount + ""); 
remoteViews.setTextViewText(R.id.text_screen_count, screenCount + ""); 
remoteViews.setTextViewText(R.id.text_field_count, fieldCount + ""); 
remoteViews.setTextViewText(R.id.text_attachment_count, attachmentCount + ""); 
mBuilder.setContent(remoteViews); 
mNotificationManager.notify(1, mBuilder.build());

此佈局文件用於膨脹的通知內容

因爲'RelativeLayout'與'android.widget.RemoteViews.RemoteView'註釋 - 文檔說：*「這個註解指示視圖的一個子類alllowed與RemoteViews機制被使用。」 * – pskink
