Change font size of TextView on AppWidget

From my configure activity the user can select his/hers desired font size of the widget. I set the font size like this: 

RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget);
views.setFloat(R.id.tvConfigInput, "setTextSize", 25);

But I do not how to update the Widget with the selected size

Any suggestions?

Thanks

  • You have to use your AppWidgetManager.For example in onReceive() method of your AppWidgetProvider do some things like this:

    @Override
public void onReceive(Context context, Intent intent) {
    views = new RemoteViews(context.getPackageName(),
                    R.layout.widget);
    AppWidgetManager mManager = AppWidgetManager.getInstance(context);
    ComponentName cn = new ComponentName(context,YourAppWidgetProvider.class);
    ...
    mManager.updateAppWidget(cn, views);

}

    Here YourAppWidgetProvider is name of class that extends AppWidgetProvider.
