android - viewflipper仅下一个动画

Question

我创建了一个 viewflipper 以便在 android 中的 2 个 View 之间翻转。

问题是我想使用相同的动画在这两个 View 之间翻转(滑入)。 当我从 View 1 -> View 2 翻转时它有效，但当我从 View 2 -> View 1 翻转时它使用反向动画

当我使用 3 个 View 时，也会发生同样的情况，翻转 1->2->3 时一切正常，但在 3->1 期间使用反向动画

有什么想法吗？

如果您这样做，您将完全控制动画和翻页:

//ViewFlipper
ViewFlipper flipper;
//Four different animations
Animation OutToRight;
Animation OutToLeft;
Animation InFromRight;
Animation InFromLeft;        

OutToRight = new TranslateAnimation(
              Animation.RELATIVE_TO_PARENT,  0.0f,      Animation.RELATIVE_TO_PARENT,  +1.0f,
              Animation.RELATIVE_TO_PARENT,  0.0f, Animation.RELATIVE_TO_PARENT,   0.0f
            );
OutToRight.setDuration(500);
        OutToRight.setInterpolator(new AccelerateDecelerateInterpolator());

        OutToLeft = new TranslateAnimation(
              Animation.RELATIVE_TO_PARENT,  0.0f, Animation.RELATIVE_TO_PARENT,  -1.0f,
              Animation.RELATIVE_TO_PARENT,  0.0f, Animation.RELATIVE_TO_PARENT,   0.0f
            );
      OutToLeft.setDuration(500);
    OutToLeft.setInterpolator(new AccelerateDecelerateInterpolator());

    InFromRight = new TranslateAnimation(
              Animation.RELATIVE_TO_PARENT,  +1.0f, Animation.RELATIVE_TO_PARENT,   0.0f,
              Animation.RELATIVE_TO_PARENT,  0.0f, Animation.RELATIVE_TO_PARENT,   0.0f
            );
    InFromRight.setDuration(500);
      InFromRight.setInterpolator(new AccelerateDecelerateInterpolator());

    InFromLeft = new TranslateAnimation(
                  Animation.RELATIVE_TO_PARENT,  -1.0f, Animation.RELATIVE_TO_PARENT,  0.0f,
                  Animation.RELATIVE_TO_PARENT,  0.0f, Animation.RELATIVE_TO_PARENT,   0.0f
                );
    InFromLeft.setDuration(500);
    InFromLeft.setInterpolator(new AccelerateDecelerateInterpolator());

    //Animating Left to page 1

    flipper.setInAnimation(InFromLeft);
    flipper.setOutAnimation(OutToRight);
    flipper.setDisplayedChild(1);

    //Animating right to page 2
    flipper.setInAnimation(InFromRight);
    flipper.setOutAnimation(OutToLeft);
    flipper.setDisplayedChild(2);
