Question

这就是我创建PorgressDialog的方式：

... progressBarDialog = new ProgressDialog( context );
                  progressBarDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
progressBarDialog.show(this, "Please Wait", "Updating your GPS coordinates",false,true);


//Trigger GPS service to update coordinates
fg.myOnresume(Name);
fg.dontSendSMS();
//Sets the timer at 30 secs
timer= new Timer();
timer.schedule(new startMapActivity());
}
class startMapActivity extends TimerTask 
    {
        @Override
        public void run() 
        {
            //handler.sendEmptyMessage(0);
            Log.d("", "StartMapActivty--->>>run()");
            // Dismissing Dialog Box
            if(progressBarDialog.isShowing())
            {
                progressBarDialog.dismiss();
            }

        }
    }

所以基本上在30秒后定时器结束后我想要对话，但它不能正常工作:(请帮助。

Answer 1

您无法从非UI线程修改UI。使用handlers来执行此操作。

Answer 2

稍微改变你的代码。像：

    Runnable r = new Runnable()
    {

        public void run() 
        {
           // TODO Auto-generated method stub
           //dismiss your dialoge here....
        }
    };

你可以这样称呼：

  Handler h = new Handler();
  h.postDelayed(r, delayMillis);
