我有一个配置器活动,工作正常.当它关闭时,我在WordWidget类中调用updateAppWidget方法,并且窗口小部件更新随机数.

由于onClick,我无法做到随机数字的改变.根据日志,我输入onReceive()方法,但是关于它.

在日志中,我正在打印窗口小部件ID.我注意到,当从配置器活动运行时,它打印appWidgetId = 33,但是当我按下这个小部件时,它打印出appWidgetId = 24.

这是代码：

public class WordWidget extends AppWidgetProvider
{
 
    @Override
    public void onUpdate(Context context,AppWidgetManager appWidgetManager,int[] appWidgetIds)
    {
        //This is run when a new widget is added or when the update period expires.
        Log.v("wotd","In onUpdate(),updating " + appWidgetIds.length + " widgets");
        Log.v("wotd","   the array is " + appWidgetIds.toString());
 
        for(int x = 0; x < appWidgetIds.length; x++)
        {
            Integer appWidgetId = appWidgetIds[x];
 
 
            //Method that updates the random value
            updateAppWidget(context,appWidgetManager,appWidgetId);
        }
    }
 
    @Override
    public void onReceive(Context context,Intent intent)
    {
        super.onReceive(context,intent);
        Log.v("wotd","In onReceive() with intent=" + intent.toString());
        if (intent.getAction().equals("android.appwidget.action.APPWIDGET_UPDATE"))
        {
            Integer mAppWidgetId;
            AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(context);
 
            Bundle extras = intent.getExtras();
            if(extras != null)
            {
                Log.v("wotd","In onReceive(),extras is valid");
                mAppWidgetId = extras.getInt(AppWidgetManager.EXTRA_APPWIDGET_ID,AppWidgetManager.INVALID_APPWIDGET_ID);
 
                //If they gave us an intent without a valid widget Id,just bail.
                if (mAppWidgetId != AppWidgetManager.INVALID_APPWIDGET_ID)
                {
                    Log.v("wotd",mAppWidgetId is ok");
                    updateAppWidget(context,mAppWidgetId);
                }
            } else
            {
                Log.v("wotd",extras is INVALID");
                mAppWidgetId = AppWidgetManager.INVALID_APPWIDGET_ID;
            }
        }
 
 
    }
 
 
    static void updateAppWidget(Context context,Integer appWidgetId)
    {
        Log.v("wotd","In updateAppWidget() with appWidgetId=" + appWidgetId);
 
        //Setup onClick
        Intent widgetIntent = new Intent(context,WordWidget.class);
        widgetIntent.setAction("android.appwidget.action.APPWIDGET_UPDATE");
        widgetIntent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID,appWidgetId);
        PendingIntent widgetPendingIntent = PendingIntent.getBroadcast(context,widgetIntent,0);
 
        Integer nextNumb = new Random().nextInt(100);
        Log.v("wotd","In updateAppWidget(),nextNumb = " + nextNumb.toString());
 
        RemoteViews remoteView = new RemoteViews(context.getPackageName(),R.layout.widgetlayout);
        remoteView.setTextViewText(R.id.mainText,String.valueOf(nextNumb));
        remoteView.setOnClickPendingIntent(R.id.mainText,widgetPendingIntent);
 
        // Tell the widget manager
        appWidgetManager.updateAppWidget(appWidgetId,remoteView);
    }
}

这是日志文件,从触摸窗口小部件(注意,prefs活动也有一个日志打印输出,并显示小部件ID作为不同的数字,这个)：

05-14 17:15:47.453: V/wotd(1585): In onReceive() with intent=Intent { act=android.appwidget.action.APPWIDGET_UPDATE flg=0x10000000 cmp=com.rfxlabs.wordofthedaywidget/.WordWidget bnds=[202,177][222,201] (has extras) }
05-14 17:15:47.453: V/wotd(1585): In onReceive(),extras is valid
05-14 17:15:47.463: V/wotd(1585): In onReceive(),mAppWidgetId is ok
05-14 17:15:47.463: V/wotd(1585): In updateAppWidget() with appWidgetId=24

05-14 17：15：47.463：V / wotd(1585)：在updateAppWidget()中,nextNumb = 42

所以你可以看到,我实际上输入了我的updateAppWidget方法,但由于某些原因,appWidgetId不正确.

任何想法为什么会这样发生？非常感谢！
