android 計時器，倒計時

自己定義CountDownTimer

/** * 計時器 * @author Administrator * */class TimeCount extends CountDownTimer{public TimeCount(long millisInFuture, long countDownInterval) {super(millisInFuture, countDownInterval);}@Overridepublic void onFinish() {}@Overridepublic void onTick(long millisUntilFinished) {//計時顯示if(millisUntilFinished/1000-1==0){//倒計時技術在handler中進行處理}tv_time.setText((millisUntilFinished/1000-1)+"s");//倒計時的時間顯示}}

調用

private TimeCount time;//計時器time=new TimeCount(60000,1000);//開始計時time.start();
