Android Java倒计时再做点什么

Question

我怎么能倒数到5然后会发生什么？

Ex：活动开始倒计时到5，然后出现祝酒词

Answer 1

您可以使用CountdownTimer in-build抽象类

来执行此操作

 new CountdownTimer(5000, 1000) {

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

     public void onFinish() {
        // Now countdown is finished, perform whatever you want
         mTextField.setText("done!");
     }
  }.start();
