更新了下模拟器录制了个效果图：后边附有代码地址：

package com.qiao.timecountdown;import android.app.Activity;import android.app.Fragment;import android.os.Bundle;import android.os.CountDownTimer;import android.view.LayoutInflater;import android.view.View;import android.view.View.OnClickListener;import android.view.ViewGroup;import android.widget.Button;/*** 获取验证码倒计时。。。。。。* @author 有点凉了* QQ群：123869487* 求基友共同进步，求大神入群指点**/public class MainActivity extends Activity {private static Button button = null;private static TimeCount time;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        time = new TimeCount(60000, 1000);//构造CountDownTimer对象        if (savedInstanceState == null) {            getFragmentManager().beginTransaction()                    .add(R.id.container, new PlaceholderFragment())                    .commit();        }    }    /**     * A placeholder fragment containing a simple view.     */    public static class PlaceholderFragment extends Fragment {            public PlaceholderFragment() {        }        @Override        public void onCreate(Bundle savedInstanceState) {        // TODO Auto-generated method stub        super.onCreate(savedInstanceState);                }        @Override        public View onCreateView(LayoutInflater inflater, ViewGroup container,                Bundle savedInstanceState) {            View rootView = inflater.inflate(R.layout.fragment_main, container, false);            button = (Button) rootView.findViewById(R.id.bt_get);            button.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {time.start();}});            return rootView;        }    }//注册计时器class TimeCount extends CountDownTimer {public TimeCount(long millisInFuture, long countDownInterval) {super(millisInFuture, countDownInterval);// 参数依次为总时长,和计时的时间间隔}@Overridepublic void onFinish() {// 计时完毕时触发button.setBackgroundResource(R.drawable.iv_getcode);button.setText("重新获取");button.setClickable(true);}@Overridepublic void onTick(long millisUntilFinished) {// 计时过程显示button.setClickable(false);button.setText(millisUntilFinished / 1000 + "秒");}}}
