RemoteView addView not working


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);

Solution

  • 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>
