android - Viewflipper - 垂直 slider

Question

我已经使用 Viewflipper 做了 slider ，我们可以说从右到左表示水平 slider 。
但我想让它从顶部(从顶部开始)到底部(从底部开始)意味着垂直 slider 。
下面是我的水平滑动代码。

public static Animation inFromRightAnimation(int duration) {
        Animation 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(duration);
        inFromRight.setInterpolator(new AccelerateInterpolator());
        return inFromRight;
    }

    public static Animation outToLeftAnimation(int duration) {
        Animation 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(duration);
        outtoLeft.setInterpolator(new AccelerateInterpolator());
        return outtoLeft;
    }

我需要做哪些更改才能使其垂直(从上到下)滑动？

Answer 1

public static Animation inFromUpAnimation(int duration) {
        Animation inFromRight = new TranslateAnimation(
        Animation.RELATIVE_TO_PARENT,  0.0f, Animation.RELATIVE_TO_PARENT,  0.0f,
        Animation.RELATIVE_TO_PARENT,  +1.0f, Animation.RELATIVE_TO_PARENT,   0.0f
        );
        inFromRight.setDuration(duration);
        inFromRight.setInterpolator(new AccelerateInterpolator());
        return inFromRight;
    }

    public static Animation outToDownAnimation(int duration) {
        Animation outtoLeft = new TranslateAnimation(
          Animation.RELATIVE_TO_PARENT,  0.0f, Animation.RELATIVE_TO_PARENT,  0.0f,
          Animation.RELATIVE_TO_PARENT,  0.0f, Animation.RELATIVE_TO_PARENT,  -1.0f
        );      
        outtoLeft.setDuration(duration);
        outtoLeft.setInterpolator(new AccelerateInterpolator());
        return outtoLeft;
    }

这些属性与 x 和 y 坐标有关。我认为这会完成工作
