ListView增加Animation效果

anim文件夹下建立anim_layout.xml和alpha.xml

-----------------------android:animationOrder 的取值有normal 0 默认reverse 1 倒序random 2 随机-----------------------

anim_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<layoutAnimation xmlns:android="http://schemas.android.com/apk/res/android"

 android:delay="0.5"
 android:animationOrder="random"
 android:animation="@anim/alpha"
 />

alpha.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
    	android:interpolator="@android:anim/accelerate_interpolator">
    	
    <alpha
        android:fromAlpha="0.0"
        android:toAlpha="1.0"
        android:duration="500" />
    
</set>

布局文件里的ListView增加一个layoutAnimation属性

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <ListView 
        android:id="@id/android:list"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:drawSelectorOnTop="false"
        android:layoutAnimation="@anim/anim_layout"
        ></ListView>
    
    <TextView
        android:id="@id/android:empty"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:text="No data" />
	
</LinearLayout>
