home-screen-widget

问题 I am trying to make a home screen widget which will toggle on and off the gps (Location in settings). I still don't understand how to handle a button click event. I took this code from a tutorial online. public class LocationWidget extends AppWidgetProvider { private static String SYNC_CLICKED = "automaticWidgetSyncButtonClick"; @Override public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) { final int count = appWidgetIds.length; String status;
