Question

我使用Viewflipper做滑块，从右到左表示水平滑块我们可以说但是我想让它顶部（从顶部开始）到底部（从底部到底部）意味着垂直滑块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;
    }

我需要做什么改变才能让它垂直（从上到下）滑动？

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;
    }

与x和y坐标相关的那些属性。我认为这将完成这项工作
