Sticky ScrollView - Android

But when it comes to mobile apps, there is no direct way to implement sticky headers or footers for layouts in android. So I decided to create a library which would implement sticky behaviour with android’s ScrollView. It’s called StickyScrollView. StickyScrollView provides both sticky header as well as sticky footer. Sticky Header & Footer with android scrollView StickyScrollView can be used just like android’s scrollview. All you have to do is to replace your ScrollView in your view’s xml with StickyScrollView and specify the references to the layouts which need to be sticky. Here is an example of how a StickyScrollView can be used. <com.amar.library.ui.StickyScrollView xmlns:app="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:layout_height="match_parent" app:stickyHeader="@+id/titleLayout" app:stickyFooter="@+id/buttonLayout"> ... <LinearLayout android:id="@+id/titleLayout" android:layout_width="match_parent" android:layout_height="wrap_content"> ... </LinearLayout> <LinearLayout android:id="@+id/buttonLayout" android:layout_width="match_parent" android:layout_height="wrap_content"> ... </LinearLayout> ... </com.amar.library.ui.StickyScrollView> More details are available in github. github.com/amarjain07/StickyScrollView
