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>
