在我的应用程序中,我想在用户打开3G时设置超时...经过一段时间后,我将关闭3G ..我的问题是取消预定的计时器..每次我调用timer.cancel( )..程序抛出错误
当我调用clearTimeout()方法时问题的原因..
Timer timer;
class RemindTask extends TimerTask {
public void run() {
//do something when time's up
log("timer","running the timertask..");//my custom log method
timer.cancel(); //Terminate the timer thread
}
}
public void setTimeout(int seconds) {
timer = new Timer();
timer.schedule(new RemindTask(), seconds*1000);
}
public void clearTimeout(){
log("timer", "cancelling the timer task");//my custom log method
timer.cancel();
timer.purge();
}
