问题
I have an app widget and I'd like to add Views (TextView
, etc.,) to the RemoteView
but it never shows up.
Here goes the code:
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);
Any ideas?
This is what I ended up doing:
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);

The addView() method needs the id of the view inside the layout you want to add this new view to, not the layout itself.
Instead of this:
views.addView(views.getLayoutId(), newView);
Try this:
views.addView(R.id.view_container, newView);
Assuming your layout looks something like this:
file: 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>
