ProgressDialog程序开始先加载数据

mProgressDlg = ProgressDialog.show(this, "App_Name", "Loading data...", 
                                        true, false);
  new Thread(new Runnable(){
                public void run() {
                        /*Load Data*/
                        mProgressDlg.dismiss();
                        hRefresh.sendEmptyMessage(REFRESH);
                }
        }).start();



Handler hRefresh = new Handler(){

@Override
public void handleMessage(Message msg) {
       switch(msg.what){
         case REFRESH:
                /*Refresh UI*/
                break;
       }
    }
};
