Android编程实现加载等待ProgressDialog的方法

import android.app.ProgressDialog;
import android.content.Context;
import android.content.DialogInterface;
import android.content.DialogInterface.OnCancelListener;
public class ShowProgressDialog {
  public static ProgressDialog wait;
  public static void show(Context context,String msg,Thread thread) {
    final Thread th = thread;
    wait = new ProgressDialog(context);
    //设置风格为圆形
    wait.setProgressStyle(ProgressDialog.STYLE_SPINNER);
    wait.setTitle(null);
    wait.setIcon(null);
    //设置提示信息
    wait.setMessage(msg);
    //设置是否可以通过返回键取消
    wait.setCancelable(true);
    wait.setIndeterminate(false);
    //设置取消监听
    wait.setOnCancelListener(new OnCancelListener() {
      @Override
      public void onCancel(DialogInterface dialog) {
        th.interrupt();
      }
    });
    wait.show();
  }
}
