我有一个应用程序小部件,我想将 View (TextView等)添加到RemoteView中,但它从未显示出来。
代码如下:

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);

有任何想法吗?

这是我最终要执行的操作:
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);

最佳答案

addView()方法需要在要向其中添加新 View 的布局内的 View ID,而不是布局本身。

代替这个:

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

试试这个:
views.addView(R.id.view_container, newView);

假设您的布局看起来像这样:

文件:布局/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>
