Question

我使用自定义列表视图来显示项目列表，每个项目都是我的对象的实例，上面有一个按钮。我为某个项的按钮设置了ValueAnimator，其属性为isAnim = true。看起来没问题，但是当我向下滚动列表视图时，其中一些项目是＆＃39; isAnim = false＆＃39;还有动画。这是我的代码动画：

protected void blinkblinkImage(Button bt) {

    ValueAnimator colorAnim = ObjectAnimator.ofInt(bt, "textColor", activity.getResources().getColor(R.color.white),
                                                    activity.getResources().getColor(R.color.cam),
                                                    activity.getResources().getColor(R.color.blue1),
                                                    activity.getResources().getColor(R.color.red),
                                                    activity.getResources().getColor(R.color.yellow));
    colorAnim.setDuration(300);
    colorAnim.setEvaluator(new ArgbEvaluator());
    colorAnim.setRepeatCount(ValueAnimator.INFINITE);
    colorAnim.setRepeatMode(ValueAnimator.REVERSE);
    colorAnim.start();

}

这里是为项目设置动画

@Override
public View getView(final int position, View convertView, ViewGroup parent) {
    View view = convertView;

    if(convertView == null)
        view = inflater.inflate(R.layout.item_xe, null);
    final Button btTT = (Button) view.findViewById(R.id.bt_tt);

    final HashMap<String, String> itemxe = data.get(position);

    final Boolean isAnim = itemxe.get(Login_Activity.TAG_ANIM);


    if(isAnim)
        blinkblinkImage(btTT);


    return view;
}

尝试以下代码：

  protected void blinkblinkImage(Button bt) {

    ValueAnimator colorAnim = ObjectAnimator.ofInt(bt, "textColor", activity.getResources().getColor(R.color.white),
                                                    activity.getResources().getColor(R.color.cam),
                                                    activity.getResources().getColor(R.color.blue1),
                                                    activity.getResources().getColor(R.color.red),
                                                    activity.getResources().getColor(R.color.yellow));

    bt.setHasTransientState(true);
    colorAnim.setDuration(300);
    colorAnim.setEvaluator(new ArgbEvaluator());
    colorAnim.setRepeatCount(ValueAnimator.INFINITE);
    colorAnim.setRepeatMode(ValueAnimator.REVERSE);
    colorAnim.addListener(new AnimatorListenerAdapter{
    @Overrid 
    public void onAnimationEnd(Animator animation){

         bt.setHasTransientState(false);
    }

    });
    colorAnim.start();

}
