本人小白，那个大神看到有问题可指出，谢谢。。。 

再根据上编的基础上再添加倒计时即可

添加一个类TimeCountUtil

package zhu.com.yzm4;

import android.os.CountDownTimer;
import android.widget.Button;

/**
* Created by kqw on 2018/1/24
* TimeCountUtil
*/
public class TimeCountUtil extends CountDownTimer {
private Button mButton;

public TimeCountUtil(Button button, long millisInFuture, long countDownInterval) {
super(millisInFuture, countDownInterval);
this.mButton = button;
}

@Override
public void onTick(long millisUntilFinished) {
// 按钮不可用
mButton.setEnabled(false);
String showText = millisUntilFinished / 1000 + "秒后可重新发送";
mButton.setText(showText);
}

@Override
public void onFinish() {
// 按钮设置可用
mButton.setEnabled(true);
mButton.setText("重新获取验证码");
}
}

 

  在主方法里面MainActivity类中 定义 TimeCountUtil  的变量 

 


 

private TimeCountUtil mTimeCountUtil;

在onCreate方法里面创建 mTimeCountUtil 的实例，设置倒计时的时间



 

//btn_getCord这个是点击获取验证码的按钮哦
mTimeCountUtil = new TimeCountUtil(btn_getCord, 10000, 1000);//这里的倒计时的时间 是 ：用第二参数 / 第三个三参数 = 倒计时为10秒

在点击触发的 case R.id.btn_getcord://Button的点击获取事件中 触发倒计时时间的事件

mTimeCountUtil.start();

完整的MainActivity
