4. 带进度条的对话框

final ProgressDialog dialog = new ProgressDialog(this);dialog.setTitle("进度条对话框");dialog.setMessage("正在加载...");dialog.show();new Timer().schedule(new TimerTask() {public void run() {runOnUiThread(new Runnable() {public void run() {dialog.dismiss();}});}}, 3000);

注意：

   1. AlertDialog对话框：点击按钮(PositiveButton和NegativeButton)的同时会自动关闭对话框，然后点击选项时却不会。

   2. 强制关闭对话框可以调用DialogInterface接口的dismiss()方法。

   3. 带进度条的对话框需要使用ProgressDialog类创建。
