AdapterViewFlipper学习笔记

布局：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.example.adapterviewflipper.MainActivity" >

    <AdapterViewFlipper
        android:id="@+id/flipper"
        android:layout_height="match_parent"
        android:layout_width="match_parent"
        android:flipInterval="3000"
        android:layout_alignParentTop="true"></AdapterViewFlipper>

    <Button
        android:id="@+id/last"
        android:text="上一个"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"

        android:layout_alignParentBottom="true"/>

    <Button
