Android实现发送验证码倒计时的效果

public class CountDownUtil extends CountDownTimer {

private Button mButton;

//参数说明 button 就是你要实现点击的那个按钮  第二个是你设设置的总时间 第三个参数是间隔时间
public CountDownUtil(Button button, long millisInFuture, long countDownInterval) {
super(millisInFuture, countDownInterval);
this.mButton = button;
}

@Override
public void onTick(long millisUntilFinished) {

mButton.setClickable(false);

mButton.setText(millisUntilFinished / 1000 +"秒后可发送");  //

}

@Override
public void onFinish() {
mButton.setClickable(true);
mButton.setText("获取");

}
}

CountDownUtil countDownUtil =new CountDownUtil(vercodebtn,60000,1000);  // vercodebtn 就是你的那个按钮
countDownUtil.start();
