我想用动画制作一个0-9的随机数。
我尝试与$ docker system prune
WARNING! This will remove:
- all stopped containers
- all networks not used by at least one container
- all dangling images
- all build cache Are you sure you want to continue? [y/N] y
一起使用，但是没有运气。
这是我的没有ValueAnimator的代码（有效）：
ValueAnimator final int min = 0;
final int max = 9;
final int random = new Random().nextInt((max - min) + 1) + min;
randomSting = String.valueOf(random);
mNumberView.setText(randomSting);
在这里不起作用（不起作用）：
ValueAnimator animator = ValueAnimator.ofInt(0, 9);
final int min = 0;
final int max = 9;
final int random = new Random().nextInt((max - min) + 1) + min;
randomSting = String.valueOf(random);
cTimer = new CountDownTimer(3000, 1000) {
public void onTick(long millisUntilFinished) {
animator.setDuration(3000);
animator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
public void onAnimationUpdate(ValueAnimator animation) {
mNumberView.setText(animation.getAnimatedValue().toString());
}
});
animator.start();
}
public void onFinish() {
animator.cancel();
mNumberView.setText(randomSting);
}
};
cTimer.start();
无法将文本设置为mNumberView。
如果可以使数字动画师具有随机数，请不要使用randomString
答案 0 :(得分：2)
此代码将每1秒钟生成9到0之间的随机数。
final int min = 0;
final int max = 9;
final int duration= 1000;
final Handler handler = new Handler();
final Runnable runnable = new Runnable() {
@Override
public void run() {
int random = new Random().nextInt(max - min + 1) + min;
handler.postDelayed(this,duration);
}
};
handler.post(runnable);
