第二个视图的 viewflipper 问题

Question

我是 Android 新手，无法解决视图翻转器的问题。当我单击第二个视图中的按钮时，第三个视图应该出现并带有 infromright() 动画。但与此同时，第一个视图也与第三个视图一起出现，并在内部翻译并消失。这不应该发生

如何阻止这种情况，

这里的任何想法都是代码

public class gif extends Activity {
    ViewFlipper flipper;
  //    RelativeLayout r1 = (RelativeLayout)findViewById(R.id.second_view);



    private Animation inFromTopAnimation() {

    Animation inFromTop = 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
    );
    inFromTop.setDuration(1000);
    inFromTop.setInterpolator(new AccelerateInterpolator());
    return inFromTop;
    }
    private Animation outToBottomAnimation() {
    Animation outtoBottom = new TranslateAnimation(
