RemoteView addView無法正常工作

Question

我有一個應用程序小部件，我想向RemoteView添加視圖（TextView等），但它永遠不會顯示。
這裏去代碼：

RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget_layout); 
RemoteViews newView = new RemoteViews(context.getPackageName(), R.layout.widget_row_layout); 
    newView.setTextViewText(R.id.textUser, "1234"); 
    views.addView(views.getLayoutId(), newView); 
// Tell the AppWidgetManager to perform an update on the current App Widget 
appWidgetManager.updateAppWidget(appWidgetId, views); 

任何想法？

這是我落得這樣做：

RemoteViews newView = new RemoteViews(context.getPackageName(), R.layout.widget_row_layout); 
    newView.setTextViewText(R.id.textUser, "1234"); 
ComponentName thisWidget = new ComponentName(this,WidgetProvider.class); 
AppWidgetManager manager = AppWidgetManager.getInstance(this); 
    manager.updateAppWidget(thisWidget, newView); 

Answer 1

的addView（）方法需要裏面的佈置要將此新視圖添加到視圖的ID，而不是佈局本身。

取而代之的是：

views.addView(views.getLayoutId(), newView); 

試試這個：

views.addView(R.id.view_container, newView); 

假設您的佈局看起來是這樣的：

文件：佈局/ widget_layout.xml

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content"> 
    <LinearLayout 
     android:id="@+id/view_container" 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content"> 
     <!-- New views will be added here at runtime --> 
    </LinearLayout> 
</LinearLayout>
