            setResult(RESULT_OK, resultValue);

            PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, configIntent, 
                                                            PendingIntent.FLAG_UPDATE_CURRENT);

            views.setOnClickPendingIntent(R.id.callbackwidget, pendingIntent);

            AppWidgetManager.getInstance(context).updateAppWidget(appWidgetId, views);

问题是，当我添加小部件IT无法点击。重启手机后，它工作确定。同时部署新的Build版本后，小部件是可以点击

Problem is when i add widget IT IS NOT CLICKABLE. after rebooting phone it is working ok. also after deploying new build version, widget IS CLICKABLE

什么想法？

推荐答案

大。问题是在不发送 ACTION_APPWIDGET_UPDATE。所以收preferences之前我发送广播消息：

great. problem was on NOT SENDING ACTION_APPWIDGET_UPDATE. so before closing preferences i send broadcast:

Intent updateIntent = new Intent(this, CallBackWidget.class);
updateIntent.setAction("PreferencesUpdated");
updateIntent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId);
sendBroadcast(updateIntent);

和在小部件的onReceive方法我检查广播

and in onreceive method of widget i check for broadcast

if ("PreferencesUpdated".equals(action)) {
AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(context);
int appWidgetId = intent.getExtras().getInt(AppWidgetManager.EXTRA_APPWIDGET_ID);
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.main);
appWidgetManager.updateAppWidget(appWidgetId, views);
int[] appWidgetIds = new int[] {appWidgetId};
onUpdate(context, appWidgetManager, appWidgetIds);
        }           

现在它就像一个魅力;）

now it works like a charm ;)
