添加延迟进度对话框 [英] Add a delay to Progress Dialog

问题描述

我想打一个假的进度对话框出现2或3秒。它实际上并不会做任何事不是说检测等。我有code：

I want to make a dummy progress dialog appear for 2 or 3 seconds. It won't actually do anything other than say detecting. I have the code:

    ProgressDialog dialog = ProgressDialog.show(this, "", "Detecting...",
            true);
    dialog.show();

    dialog.dismiss();

但我唱戏，并解雇有对话框出现了几秒钟之间？谢谢！

But what do I put in between the show, and the dismissal to have the dialog appear for a few seconds? Thanks!

推荐答案

正确的方法 - 它不会阻止你的主线程，所以用户界面保持响应：

The correct way - it does not block your main thread, so UI stays responsive:

dialog.show();

Handler handler = new Handler();
handler.postDelayed(new Runnable() {
    public void run() {
        dialog.dismiss();
    }}, 3000);  // 3000 milliseconds
