倒计时的实现

int mAnimationPlayTime = 15;

final Timer timer = new Timer();

TimerTask timerTask2 = new TimerTask() {

@Override
public void run() {
runOnUiThread(new Runnable() {

@Override
public void run() {
mAnimationPlayTime--;
textView.setText("" +mAnimationPlayTime);
if(mAnimationPlayTime == 0){
timer.cancel();
}
}
});

}
};

timer.schedule(timerTask2, 1000, 1000);
