Android One activity multiple listview

When we write three ListView directly in the layout file, three scroll bars appear, and each ListView displays only one item, and more is displayed to change. What's the best way to do that?

There are some ways to do this: include a large layout with a scrollview, and add the three ListView to the inside.

Create a new layout file:

<?xml version= "1.0" encoding= "Utf-8"?>
<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" >


<scrollview
Android:id= "@+id/scrollview"
Android:layout_width= "Fill_parent"
android:layout_height= "Wrap_content"
Android:fadingedge= "None"
android:scrollbars= "Vertical" >
<linearlayout
Android:id= "@+id/linearlayout"
Android:layout_width= "Match_parent"
android:layout_height= "Fill_parent"
android:orientation= "Vertical" >
</LinearLayout>
</ScrollView>


</LinearLayout>

}

The height where the ListView is set is the focus.
