Android completes the sliding effect by adding ListView to the ViewPage (similar to the QQ sliding interface) _android

FileName: page.xml

Copy Code code as follows:

<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" >

<listview
Android:id= "@+id/listview"
Android:layout_width= "Match_parent"
android:layout_height= "Wrap_content"/>

</RelativeLayout>

FileName: listviewitem.xml

Copy Code code as follows:

<linearlayout 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"
android:orientation= "Vertical" >

<textview
Android:id= "@+id/textview"
Android:layout_width= "Fill_parent"
android:layout_height= "Wrap_content"
android:text= "Hello"
Android:textcolor= "#00ff00"
/>
<imageview
Android:id= "@+id/imageview"
Android:layout_width= "Fill_parent"
android:layout_height= "Wrap_content"
Android:layout_margin= "5DP"
/>
</LinearLayout>

The second layout file above is available only to Simpleadapter

It's hard to understand that the newly added view automatically binds a parent class, because a son view cannot be related to two parent classes, so you have to unbind
Failure to do so would otherwise produce Viewpager java.lang.IllegalStateException:The specified child already has a parent. You are must call Removeview () on the child ' s parent.
Another method is Viewpager.setoffscreenpagelimit (3); This method does not judge whether parent is already present, but the superfluous ListView cannot be destroy
