android 利用ViewFlipper來實現滑動切換Activity

1：先看下顯示吧 

看下滑動切換後的activity

 

2：先看slide.XML布局吧:

</p><p><relativelayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="fill_parent" android:layout_height="fill_parent" tools:context=".SlideActivity"></p><p> <viewflipper android:id="@+id/viewflipper" android:layout_width="match_parent" android:layout_height="match_parent" android:text="@string/hello_world"></p><p></viewflipper></relativelayout><br />

3:如果想通過滑動（手勢）來實現滑動Activity，需要實現OnGestureListener介面，主要是實現兩個方法 onFling()和onTouchEvent()方法：，並通過viewflipper的setInAnimation方法來實現activity的切換動畫，該動畫需要在res/下建立anim檔案夾，具體的動畫.xml檔案請看

第4點：直接上代碼吧
