Hi i've never worked with widgets before but what i'm looking to do is create a very simple widget i basically want to make a 1 by 1 widget that has just an icon, just an image set as the background no text nothing just a small icon and when the icon is pressed i want to open an activity. Basically i want to make a second icon like in the app drawer in a widget form that opens another activity rather than the main one. Any help is greatly appreciated

推荐答案

我的供应商最终看上去像这样大量的调查研究后，玩

My provider ended up looking like this after a lot of research and playing

public class WidgetProvider extends AppWidgetProvider {
    @Override
    public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
        final int N = appWidgetIds.length;

        for (int i=0; i<N; i++) {
            int appWidgetId = appWidgetIds[i];

            Intent intent = new Intent(context, ClassToLaunchHere.class);
            PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);

            RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget);
            views.setOnClickPendingIntent(R.id.widget, pendingIntent);

            appWidgetManager.updateAppWidget(appWidgetId, views);
        }
    }
}
