直接进入主题，先来看看效果：

 

从右往左触摸屏幕：

 

实现：main.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout android:layout_height="fill_parent" android:layout_width="fill_parent" android:orientation="vertical" xmlns:android="http://schemas.android.com/apk/res/android" ><ViewFlipper android:id="@+id/flipper" android:layout_height="fill_parent" android:layout_width="fill_parent"><include android:id="@+id/firstlayout" layout="@layout/left"/><include android:id="@+id/secondlayout" layout="@layout/center"/><include android:id="@+id/thirdlayout" layout="@layout/right"/></ViewFlipper></LinearLayout>

 

center.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout android:gravity="center_vertical" android:layout_height="fill_parent" android:layout_width="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"> <ImageView android:layout_height="wrap_content" android:layout_width="wrap_content" android:src="@drawable/a3"></ImageView></LinearLayout>

 

left.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout android:gravity="center_vertical"android:layout_height="fill_parent" android:layout_width="fill_parent"xmlns:android="http://schemas.android.com/apk/res/android"><ImageView android:layout_height="wrap_content"android:layout_width="wrap_content" android:src="@drawable/a2"></ImageView></LinearLayout>

 

right.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout android:gravity="center_vertical"android:layout_height="fill_parent" android:layout_width="fill_parent"xmlns:android="http://schemas.android.com/apk/res/android"><ImageView android:layout_height="wrap_content"android:layout_width="wrap_content" android:src="@drawable/a1"></ImageView></LinearLayout>

 

主配置文件：AndroidManifest.xml
