想用1秒的延迟显示号码 [英] Want to display number with 1sec delay

问题描述

我想在这样一个TextView显示数字：

I want to display numbers in a TextView like this:

Wait 5 sec // then a delay of 1 sec
Wait 4 sec // display this in the same text view along with delay
Wait 3 sec // display this in the same text view along with delay
Wait 2 sec // display this in the same text view along with delay
Wait 1 sec // display this in the same text view along with delay

我想执行一个按钮点击这个动作，它应该像一个倒计时器。

I want perform this action on a button click and it should work like a count down timer.

推荐答案

您可以使用这一个

new CountDownTimer(30000, 1000) {

     public void onTick(long millisUntilFinished) {
         mTextField.setText("Wait: " + millisUntilFinished / 1000);
     }

     public void onFinish() {
         mTextField.setText("done!");
     }
  }.start();

这Timer类可以在开始按钮点击的时候，你也可以调整总时间和刻度间隔

This timer class can start at the time of button click and also you can adjust the total time and the tick interval

这是从开发网站
