android用于定时任务工具类

//用于定时任务public class BaseTimer {    private TimerCallBack timerCallBack = null;    private boolean timerRun = false;    private boolean bInterval = false;    private long curMsecond = 0;    /**     * 回调接口定义     */    public interface TimerCallBack    {        public void callback();    }    private Handler timerHandler = new Handler() {        @Override        public void handleMessage(Message msg) {            if (timerCallBack!= null)            {                timerCallBack.callback();            }            timerRun = false;            if (bInterval)            {                startTimer(curMsecond, timerCallBack);                bInterval = true;            }            super.handleMessage(msg);        }    };    private Runnable keyRunnable = new Runnable() {        @Override        public void run() {            timerHandler.sendEmptyMessage(0);        }    };    /**     * 关闭定时器     */    public void killTimer()    {        bInterval = false;        timerRun = false;        try {            timerHandler.removeCallbacks(keyRunnable);        } catch (Exception e) {        }    }    /**     * 启动延时器     * @param msecond 毫秒     * @param cb      回调函数     */    public void startTimer(int msecond, TimerCallBack cb)    {        killTimer();        curMsecond = msecond;        timerRun = true;        timerCallBack = cb;        timerHandler.postDelayed(keyRunnable, curMsecond);    }    /**     * 启动延时器     *     * @param msecond 毫秒     * @param cb      回调函数     */    public void startTimer(long msecond, TimerCallBack cb)    {        killTimer();        timerRun = true;        timerCallBack = cb ;        timerHandler.postDelayed(keyRunnable, msecond);    }    /**     * 启动定时器     *     * @param msecond 毫秒     * @param cb      回调函数     */    public void startInterval(int msecond, TimerCallBack cb)    {        startTimer(msecond, cb);        bInterval = true;    }    /**     * 获取定时器是否运行     */    public boolean isRunning()    {        return timerRun;    }}
