本文详细介绍了如何使用XML配置文件实现布局动画，并通过示例展示了如何在LinearLayout中应用特定的动画效果。

需要两个配置文件，layout_animation_table.xml：

<?xml version="1.0" encoding="utf-8"?>

<layoutAnimation xmlns:android="http://schemas.android.com/apk/res/android"
        android:delay="50%"
        android:animation="@anim/slide_top_to_bottom" />

和slide_top_to_bottom.xml

<?xml version="1.0" encoding="utf-8"?>

<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:interpolator="@android:anim/accelerate_interpolator" >

    <translate
        android:duration="100"
        android:fromYDelta="-100%"
        android:toXDelta="0" />

    <alpha
        android:duration="50"
        android:fromAlpha="0.0"
        android:toAlpha="1.0" />

</set>

然后在相应的布局上加上：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:layoutAnimation="@anim/layout_animation_table"
    android:animationCache="false"
    android:clipToPadding="false"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" />


就好
