我无法为膨胀的布局放置视图动画。我使用了以下代码片段

pageView.startAnimation(AnimationUtils.loadAnimation(this,R.anim.right_to_left_anim.xml));

和xml

<set xmlns:android="http://schemas.android.com/apk/res/android"
         android:shareInterpolator="false">
     <translate android:fromXDelta="0%" android:toXDelta="100%"
          android:fromYDelta="0%" android:toYDelta="0%"
         android:duration="700"/>

</set>

我有什么遗漏吗？

谢谢。

这是视图滑动动画的代码。

1)inFromRightAnimation

    private Animation inFromRightAnimation() {

        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(500);
        inFromRight.setInterpolator(new AccelerateInterpolator());
        return inFromRight;
        }

 2)outToLeftAnimation   
    private Animation outToLeftAnimation() {
    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(500);
    outtoLeft.setInterpolator(new AccelerateInterpolator());
    return outtoLeft;
    }

3)inFromLeftAnimation

    private Animation inFromLeftAnimation() {
    Animation 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 AccelerateInterpolator());
    return inFromLeft;
    }

4)outToRightAnimation

    private Animation outToRightAnimation() {
    Animation 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 AccelerateInterpolator());
    return outtoRight;
    }

现在在视图上启动动画

pageView.startAnimation(inFromRightAnimation());

谢谢，

如果您尝试在第一次创建视图时为其设置动画，那么您需要设置layoutAnimationXML 属性或调用setLayoutAnimation().

如果你只是想让你的视图看起来像在移动，你需要一个TranslateAnimation; 看到这个答案：https ://stackoverflow.com/a/4214490/832776 另外，如果你想重复动画，然后调用setAnimationListener()并onAnimationEnd()重新开始动画。

如果您尝试永久移动视图，请参阅：http ://www.clingmarks.com/how-to-permanently-move-view-with-animation-effect-in-android/400

我知道你已经接受了答案。但我认为这个回复对阅读这篇文章的人会有帮助。您可以尝试从中删除 .xml，pageView.startAnimation(AnimationUtils.loadAnimation(this,R.anim.right_to_left_anim.xml));
