Demo实现很简单，准备一个布局文件，其他skin1-3布局文件都一样，仅仅是图片不一样。

皮肤1布局文件skin1.xml

<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.Eric.changeskindemo.MainActivity"     android:background="@drawable/skin1"    >    <LinearLayout     android:layout_width="fill_parent"    android:layout_height="wrap_content"    android:layout_marginTop="20dp"    android:gravity="center_horizontal">    <Button         android:id="@+id/btn_skin1"        android:layout_width="80dp"        android:layout_height="40dp"        android:text="皮肤1"        android:background="@drawable/btn_skin1"/>    <Button         android:id="@+id/btn_skin2"        android:layout_width="80dp"        android:layout_height="40dp"        android:text="皮肤2"        android:background="@drawable/btn_skin2"/>    <Button         android:id="@+id/btn_skin3"        android:layout_width="80dp"        android:layout_height="40dp"        android:text="皮肤3"        android:background="@drawable/btn_skin3"/></LinearLayout>    <LinearLayout    android:layout_width="fill_parent"    android:layout_height="wrap_content"    android:layout_marginTop="100dp"    android:gravity="center_horizontal">    <ImageView         android:layout_width="100dp"        android:layout_height="100dp"        android:background="@drawable/touxiang1"/></LinearLayout></RelativeLayout>
