// 在App Widget的代码中设置点击事件监听器
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.app_widget_layout);
Intent stopIntent = new Intent(context, AppWidgetProvider.class);
stopIntent.setAction("STOP_ACTIVITY");
PendingIntent stopPendingIntent = PendingIntent.getBroadcast(context, 0, stopIntent, 0);
views.setOnClickPendingIntent(R.id.stop_button, stopPendingIntent);

// 在AppWidgetProvider中接收点击事件并停止活动
public class AppWidgetProvider extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals("STOP_ACTIVITY")) {
            // 停止当前活动
            Activity currentActivity = getCurrentActivity();
            if (currentActivity != null) {
                currentActivity.finish();
            }
        }
    }
