Android开发之ProgressDialog进度对话框用法示例

public class MainActivity extends Activity {
  final static int MAX_PROGRESS = 100;
  //虚拟 填充长度为100的数组
  private int[] data = new int[50];
  //记录进度对话框完成百分比
  int progressStatus = 0;
  int hasDta = 0;
  ProgressDialog progressDialog01,progressDialog02;
  private Button buttonDate;
  private Button buttonTime;
  //创建一个负责更新进度的Handler
  Handler mHandler = new Handler(){
    @Override
    public void handleMessage(Message msg) {
      //表明消息是本程序发送的
      if (msg.what == 0x111){
        progressDialog02.setProgress(progressStatus);
      }
    }
  };
  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    buttonDate = (Button) findViewById(R.id.dataBn);
    buttonTime = (Button) findViewById(R.id.timeBn);
    iniClick();//Binding the listeners for you program
  }
  public void showSpinner(View source){
    //用静态方法显示环形进度条
    ProgressDialog.show(this,"任务执行中","热内执行中 请等待...",false,true);
  }

    //设置对话框标题
    progressDialog01.setTitle("任务正在执行中");
    //设置对话框执行内容
