Android 获取验证码按钮倒计时实现

这个功能很常用，几乎每个app都要注册需要用的，废话不多说直接上代码

xml 里面的代码：

    android:id="@+id/regis_btn_code"
    android:layout_width="wrap_content"
    android:layout_height="@dimen/distance_twenty_seven"
    android:background="@drawable/bg_solid_gray_ten"
    android:layout_marginRight="@dimen/distance_twenty_four"
    android:layout_marginTop="@dimen/distance_two"
    android:textColor="@color/white"
    android:text="@string/obtain_code"
    android:gravity="center"
    android:paddingLeft="@dimen/distance_ten"
    android:paddingRight="@dimen/distance_ten"
    android:paddingBottom="@dimen/distance_five"
    android:paddingTop="@dimen/distance_five"
    android:textSize="@dimen/txt_twelve"
    android:enabled="false"
    android:layout_centerVertical="true"/>

点击事件实现的方法：

TimeCount timeCount = new TimeCount(frequency *time,1000,mSendCode,"重新发送");
timeCount.start();

time为时间间隔，frequency为次数，我这里间隔是60秒。

TimeCount里面的代码：

public class TimeCount extends CountDownTimer {
    private TextView mSendCode;
    private String toast;
    public  TimeCount(long millisInFuture, long countDownInterval,TextView mSendCode,String toast) {
        super(millisInFuture, countDownInterval);//参数依次为总时长,和计时的时间间隔
        this.mSendCode = mSendCode;
        this.toast = toast;
    }
    @Override
    public void onFinish() {//计时完毕时触发
        mSendCode.setText(toast);
        mSendCode.setEnabled(true);
        mSendCode.setBackgroundResource(R.drawable.bg_solid_blue_ten);
    }
    @Override
    public void onTick(long millisUntilFinished){//计时过程显示
        mSendCode.setEnabled(false);
        mSendCode.setBackgroundResource(R.drawable.bg_solid_gray_ten);
        mSendCode.setText(millisUntilFinished /1000+"秒后重试");
    }
}
