窗口小部件onClick无法正常工作

Question

惠康全部

我希望当用户按下窗口小部件时，窗口小部件会自行停止，当用户再次按下时，窗口小部件会显示其功能

我正在使用此帖子的解决方案实现onClick on my widget：Clickable widgets in android

该解决方案在Android 2.2手机和Android 4.1手机中运行良好，但在带有android 2.3.6的Nexus One上无效。我点击小部件但没有任何反应......

这是我的完整小部件类：

        public class mWidgetProvider extends AppWidgetProvider{

                PendingIntent actionPendingIntent = PendingIntent.getBroadcast(context, 0, active, 0);
                remoteViews.setOnClickPendingIntent(R.id.fondo, actionPendingIntent);           

                AppWidgetManager.getInstance(context).updateAppWidget( thisWidget, remoteViews );

                        AppWidgetManager.getInstance(context).updateAppWidget( thisWidget, remoteViews );

                    context.stopService(new Intent(context, UpdateService.class));          
                    widgetAlarm.stopAlarm();
                    remoteViews.setTextViewText(R.id.freq,"HERE I CHANGE THE VALUE");
                }
                else{ //si el widget está apagado lo encendemos
                    context.startService(new Intent(context, UpdateService.class)); 
                    widgetAlarm.startAlarm();
                            remoteViews.setTextViewText(R.id.freq,"HERE I CHANGE THE VALUE");
                }
                AppWidgetManager.getInstance(context).updateAppWidget(thisWidget,remoteViews);
            }

            private boolean isMyServiceRunning(Context context) {
                manager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
                for (RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE)) {
                    if (UpdateService.class.getName().equals(service.service.getClassName())) {
                        return true;
                    }
                }
                return false;
            }

            public void getpMaxFreq(){
                int freq = 0;
                try{            
                    //HERE I DO SOME WORK               
                }
                catch (Exception e){e.printStackTrace();}
            }
        }

PD：我尝试将意图放在onEnabled()函数中，结果相同......在带有2.3.6 Android版本的Nexus One上无效
