android--------验证码倒计时

在我们注册或者修改信息的时候，常会用到60s倒计时这个功能，写了这篇文章，大家共享一下：

效果图：

           

直接上代码：

activity.java

public class MainActivity extends Activity {

    private TimeCount mTiemTimeCount;
    private TextView tv_code;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mTiemTimeCount = new TimeCount(60000, 1000);
        initView();

    }

    private void initView() {
        // TODO Auto-generated method stub
        tv_code = (TextView) findViewById(R.id.verify_code);
        tv_code.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                mTiemTimeCount.start();
            }
        });
    }

    // 计时重发
    private class TimeCount extends CountDownTimer {

        public TimeCount(long millisInFuture, long countDownInterval) {
            super(millisInFuture, countDownInterval);
        }

        @Override
        public void onTick(long millisUntilFinished) {
            tv_code.setClickable(false);
            tv_code.setText(millisUntilFinished / 1000 + "秒后重新发送");
        }

        @Override
        public void onFinish() {
            tv_code.setText("获取验证码");
            tv_code.setClickable(true);
        }
    }
    @Override
    protected void onDestroy() {
        super.onDestroy();
        mTiemTimeCount.cancel();
    }
}

mTiemTimeCount = new TimeCount(60000, 1000);可以自己更改时间
