public class Test_ProgressDialog extends Activity {

    @Override

        btn1 = (Button) this.findViewById(R.id.Button01);
        btn2 = (Button) this.findViewById(R.id.Button02);
        btn1.setOnClickListener(new OnClickListener(){

				mpDialog = new ProgressDialog(Test_ProgressDialog.this);
				mpDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);//设置风格为圆形进度条

				mpDialog.setMessage("这是一个圆形进度条");
				mpDialog.setIndeterminate(false);//设置进度条是否为不明确

				mpDialog.setButton("确定", new DialogInterface.OnClickListener(){
