RemoteView addView不工作

Question

我有一个应用程序小部件，我想将视图(TextView等)添加到RemoteView中，但它从未出现。

下面是代码：

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);

有什么想法吗？

，这就是我最后所做的：

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

addView()方法需要要将这个新视图添加到的布局中的视图的id，而不是布局本身。

而不是这样：

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

试试这个：

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

假设您的布局如下所示：

文件：layout/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>
