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
