Android Studio使用Mob来获取手机验证码加上倒计时

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();
