ProgressDialog在UIThread未显示 [英] ProgressDialog not shown in UIThread

问题描述

我创建使用谷歌API的lib地图。因为mapwidget需要很长的时间来加载我试图增加一个装载通知，但它没有示出。我可以在普通线程，虽然显示progressDialog。为什么此对话框不显示？

 公共无效的onCreate（包savedInstanceState）{
        super.onCreate（savedInstanceState）;



        progressDialog = ProgressDialog.show（这一点，请等待，地图=加载，假的，真正的）;
        //setContentView(R.layout.map）;
        runOnUiThread（新的Runnable（）{
            公共无效的run（）{
                尝试{
                    Log.d（调试，之前的setContentView）; // 13：36：25
                    的setContentView（R.layout.map）;
                    Log.d（调试，后的setContentView）; // 13：36：39

                }赶上（例外五）{}

                progressDialog.dismiss（）;
            }}）;

        initMap（）;
        initGps（）;

    }

I'm creating a map using the google api lib. Because the mapwidget takes a long time to load I'm trying to add a loading notification, but it isn't shown. I can show the progressDialog in regular threads though. How come this dialog isn't shown?

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);



        progressDialog = ProgressDialog.show(this, "Please Wait", "Map = loading",false,true);
        //setContentView(R.layout.map);
        runOnUiThread(new Runnable(){
            public void run() {
                try{
                    Log.d("debug", "before setContentView");                        //13:36:25
                    setContentView(R.layout.map);
                    Log.d("debug", "after setContentView");                         //13:36:39

                } catch (Exception e) { }

                progressDialog.dismiss();
            }});

        initMap();     
        initGps();

    }
