Android ProgressDialog 延时消失

final ProgressDialog dialog = ProgressDialog.show(this,"正在下载，请稍候 …", true, true);

Thread t = new Thread(new Runnable() {

@Override

public void run() {

try {

Thread.sleep(10000);//10秒后，取消ProgressDialog

} catch (InterruptedException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

dialog.dismiss();

}

});

t.start();
