先上效果图：

由于时分秒都有自己的背景色等布局，所以重写一个textview 不够灵活，所以我们自己定义一个TimeTextView继承自Linearlayout 然后再在里面放几个textview即可。

先看 布局文件吧：

然后就是自己定义的linearlayout了。

/** * 倒计时 3文本 * Created By Fangchao On 2015/3/12 */public class TimeTextView extends LinearLayout {
          private long mday, mhour, mmin, msecond;//天，小时，分钟，秒    private boolean run = false; //是否启动了    Timer timer = new Timer();    TextView Vhour, Vmin, Vseconds;    public TimeTextView(Context context) {        super(context);        iniUI(context);    }    public TimeTextView(Context context, AttributeSet attrs) {        super(context, attrs);        iniUI(context);    }    public void iniUI(Context context) {        LayoutInflater mInflater = LayoutInflater.from(context);        View myView = mInflater.inflate(R.layout.view_time_texviews, null);        Vhour = (TextView) myView.findViewById(R.id.tv_hours);        Vmin = (TextView) myView.findViewById(R.id.tv_minutes);        Vseconds = (TextView) myView.findViewById(R.id.tv_seconds);        addView(myView);    }    public TimeTextView(Context context, AttributeSet attrs, int defStyleAttr) {        super(context, attrs, defStyleAttr);        iniUI(context);    }    private Handler mHandler = new Handler() {    };    public boolean isRun() {        return run;    }    public void setRun(boolean run) {        this.run = run;    }    public void start() {        if (!isRun()) {            setRun(true);            timer.schedule(task, 1000, 1000);        }    }    /**     * 依据传进来的时间差 为textview 赋值     *     * @param duration     */    public void setTimes(long duration) {        Date date = new Date(duration);        Date date1 = new Date(1L);        /*mday = duration / 60000 / 60 / 24;        mhour = (duration - mday * 6000 * 60 * 24) / 3600000;        mmin = (duration - mhour * 6000 * 60 - mday * 3600000 * 24) / 60000;        msecond = (duration - mmin * 60000 - mhour * 3600000 - mday * 3600000 * 24) / 60000;*///须要改动，測试用        mday = date.getDay();        mhour = date.getHours();        mmin = date.getMinutes();        msecond = date.getSeconds();    }    /**     * 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                    mhour = 24;                    mday--;                }            }        }    }    TimerTask task = new TimerTask() {        @Override        public void run() {            mHandler.post(new Runnable() {      // UI thread                @Override                public void run() {                    run = true;                    ComputeTime();                    if (mday < 0) {                        setVisibility(View.GONE);                        setRun(false);                    }                    Vhour.setText(mhour < 10 ? ("0" + mhour) : mhour + "");                    Vseconds.setText(msecond < 10 ?

("0" + msecond) : msecond + ""); Vmin.setText(mmin < 10 ? ("0" + mmin) : mmin + ""); } }); } }; }

用的时候直接在须要的地方直接把TimeTextview 放上即可了，

举个样例吧，能够在adapter中设置倒计时时长。。。。

@Override    public void onBindHeaderView(RecyclerView.ViewHolder holder, int position) {        HeaderViewHolder headViewHolder = (HeaderViewHolder) holder;        long duration=  1426244976513L + 200 * 1000 - TimeUtils.getCurrentTimeInLong();        Log.e("long///", TimeUtils.getCurrentTimeInLong() + "");        if (!headViewHolder.timeTextView.isRun()) {            headViewHolder.timeTextView.setTimes(duration);            headViewHolder.timeTextView.start();        }    }
