This article illustrates how Android implements the activity level and the vertical scroll bar. Share to everyone for your reference, specific as follows:
<scrollview xmlns:android= "http://schemas.android.com/apk/res/android"
android:layout_width= "Match_ Parent "
android:layout_height=" match_parent "
android:scrollbars=" vertical ">
< Horizontalscrollview
android:layout_width= "wrap_content"
android:layout_height= "Wrap_content"
>
<linearlayout
android:orientation= "vertical"
android:layout_width= "Fill_parent"
android: layout_height= "Fill_parent"
>
</LinearLayout>
</HorizontalScrollView>
</ Scrollview>
The root tag is the scrollview below the Horizontalscrollview, and then Horizontalscrollview below is your own layout.
Only one label can be embedded under Ps:scrollview and Horizontalscrollview labels
