在xml中的使用方法：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:orientation="vertical" > <com.yw.sortlistview.IndexAnimationLinearLayout
android:id="@+id/layoutanimation_linear"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#ffff99"
android:orientation="horizontal" > </com.yw.sortlistview.IndexAnimationLinearLayout>
<TextView
android:id="@+id/layoutanimation_tv_title"
android:layout_width="300dp"
android:layout_height="wrap_content"
android:gravity="center"
android:layout_marginTop="10dp"
android:text="第一个"
/>
</LinearLayout>
结束。
