Android Implementation ProgressDialog Wait interface

1. Define Dialog

private ProgressDialog dialog;

2. Defining Handler Objects

private Handler handler =new Handler(){   @Override   //当有消息发送出来的时候就执行Handler的这个方法   publicvoidhandleMessage(Message msg){      super.handleMessage(msg);      //只要执行到这里就关闭对话框      dialog.dismiss();   }};

3. Implementing the Code

privatevoidprocessThread(){      //构建一个下载进度条      dialog= ProgressDialog.show(MainHandler.this"Load""Loading…");      new Thread(){         publicvoidrun(){            //在新线程里执行长耗时方法            longTimeMethod();            //执行完毕后给handler发送一个空消息            handler.sendEmptyMessage(0);         }      }.start();
