Android倒计时控件

项目有一个倒计时特卖的需求
具体代码如下

import android.content.Context;import android.util.AttributeSet;import android.widget.TextView;public class TimerTextView extends TextView implements Runnable{    public TimerTextView(Context context, AttributeSet attrs) {        super(context, attrs);        // TODO Auto-generated constructor stub    }    private long mday, mhour, mmin, msecond;//天，小时，分钟，秒    private boolean run=false; //是否启动了    public void setTimes(long[] times) {        mday = times[0];        mhour = times[1];        mmin = times[2];        msecond = times[3];    }    /**     * 倒计时计算     */    private void ComputeTime() {        msecond--;        if (msecond < 0) {            mmin--;            msecond = 59;            if (mmin < 0) {                mmin = 59;                mhour--;                if (mhour < 0) {                    // 倒计时结束，一天有24个小时                    mhour = 23;                    mday--;                }            }        }    }    public boolean isRun() {        return run;    }    public void beginRun() {        this.run = true;        run();    }    public void stopRun(){        this.run = false;    }    @Override    public void run() {        //标示已经启动        if(run){            ComputeTime();            String strTime= mday +"天:"+ mhour+"小时:"+ mmin+"分钟:"+msecond+"秒";            this.setText(strTime);            postDelayed(this, 1000);        }else {            removeCallbacks(this);        }    }}

使用也很简单

            long[] times = {0,shi,fen,miao}; //参数分别是 天 时 分 秒            holderView.tv_countdowntimer.setTimes(times);            if(!holderView.tv_countdowntimer.isRun()){                  holderView.tv_countdowntimer.beginRun();              }
