Question

我正在创建具有太多动画的活动，并且在开始此活动时，logcat会在此活动的生命周期内一次又一次地向我显示此消息：

I/Choreographer﹕ Skipped 36 frames!  The application may be doing too much work on its main thread.

所以我在另一个线程中做了很多东西，但仍然在主UI线程上有大量访问权限。而且，动画在一些高分辨率设备上变得非常慢

处理此问题的可行解决方案是什么？

更新：添加代码

所以这里是显示视图的代码（6个imageButtons），

private void setupAnimationForAllViews(ArrayList<View> listOfViews,
                                       int animationId,
                                       final boolean isAppearing) {
    int startDelay = mDelay; // milliseconds
    int numberOfViews = listOfViews.size();

    for (int i = 0; i < numberOfViews; i++) {
        final Animation animator = AnimationUtils.loadAnimation(mContext, animationId);
        animator.setStartOffset(startDelay);
        startDelay += mOffSet; // every view will start after 100 milliseconds from the other
        final View currentView = listOfViews.get(i);
        final int indexOfCurrentCheckedItem = i;

        mMainUIThreadHandler.post(new Runnable() {
            @Override
            public void run() {
                currentView.startAnimation(animator);
            }
        });
    }
}

我在这样的分离线程中触发它：

new Thread(new Runnable() {
        @Override
        public void run() {
            setupAnimationForAllViews(tempListOfViews, 
                animationId, isAppearing);
        }
    }).start();

在同一活动中，我有Ken Burns View，它对2张图片实施ken burns效果，此kenBurnsView的代码在此链接中：KenBurnsView

所以这是主要的活动xml：

这是java的主要活动部分：

Answer 1

我缩小了Kenburns和按钮背景图像的大小和分辨率，以使其顺利运行。玩线程并没有解决我的滞后问题。

从其他线程处理主ui线程上的动画请求太多 - android
