Question

朋友我正在为Android构建一个应用程序并且在显示动态添加TextViewer时面临一些问题我的方案是这样的。我正在使用ResulReceiver来接收notification并在TextView中动态添加此结果以显示。当我的活动处于活动状态I.e The application is keep open时，它才能正常运行。当我的活动不在Active模式时，我将其存储到DB (SQLLITE)，但当我再次回到我的活动时，我可以从数据库中获取数据并执行相同的操作之前，直到现在都没有问题。但它开始，因为我当时收到新的通知无法动态地附加现有的新TextView，但是从调试目的来看，我使用Toast它正常显示。你能帮帮我吗？提前致谢。 这是我的代码

 @Override
    public void onReceiveResult(int resultCode, Bundle resultData) {
        // TODO Auto-generated method stub
        String result = resultData.getString("notifyService");
        CustomActionBar.controlNotifyImage(this,mActionBar);
        ActivityManager activityManager = (ActivityManager)getSystemService(ACTIVITY_SERVICE);
        List<ActivityManager.RunningTaskInfo> taskInfo = activityManager.getRunningTasks(1);
        ComponentName componentInfo = taskInfo.get(0).topActivity;
        if(!".activity.CatagoryChooserActivity".equals(componentInfo.getShortClassName()) ){
            notifyInfo = new NotifyInfo();
            notifyInfo.setNotifyPk(100000+new Long(CreateOrderService.notifyCount.get()));
            notifyInfo.setNotifyTxt(result);
            notifyInfo.setNotifyDate(new Date().toString());
            notifyInfo.setNotifyTime(new Date().toGMTString());
            SellerNotifyDB sellerNotifydb = SellerNotifyDB.getInstance(context);
            sellerNotifydb.addNotification(notifyInfo);

Answer 1

我认为你需要停止现有的运行服务。

Answer 2

将现有TextView保留在LinearLayout中，然后生成TextView并添加到LinearLayout。见this

无法动态地附加TextView与现有的TextView
