android - 在警报对话框中显示倒数计时器

Question

我如何在我的警报框中显示倒数计时器。我想通知用户 session 将在 5 分钟后结束，并在警报弹出框中显示正在运行的计时器..

Answer 1

弹出框应该有一个alertDialog:

alertDialog = new AlertDialog.Builder(this).create();  
alertDialog.setTitle("Alert 3");  
alertDialog.setMessage("00:10");
alertDialog.show();   // 

new CountDownTimer(10000, 1000) {
    @Override
    public void onTick(long millisUntilFinished) {
       alertDialog.setMessage("00:"+ (millisUntilFinished/1000));
    }

    @Override
    public void onFinish() {
        info.setVisibility(View.GONE);
    }
}.start();
