smooth-app-bar-layout [Deprecated]

================

[DEPRECATED] The issue that is addressed in this library is fixed from support design 26.0.0 or above (finally). Please use support design instead.

This is a smooth version of Google Support Design AppBarLayout. If you are using AppBarLayout, you will know it has an issue with fling. Check out these threads to know about that problem: http://stackoverflow.com/questions/30923889/flinging-with-recyclerview-appbarlayout https://code.google.com/p/android/issues/detail?id=177729...

If you find that it still doesn't meet your need, don't hesitate to send me a request. I love to work with you to solve problems. Send a request HERE

Installation

compile "me.henrytao:smooth-app-bar-layout:<latest-support-design-version>.<latest-smooth-app-bar-layout-fix>"

Example: if the latest support design version is 24.1.0 and SmoothAppBarLayout fix is 0, please use compile "me.henrytao:smooth-app-bar-layout:24.1.0.0". Please check TAGS section to see all supported versions.

smooth-app-bar-layout is an UI library and pretty much depended on AppCompat and Support Design. So that, versioning is quite the same with those libraries from Google.
smooth-app-bar-layout is deployed to jCenter. Make sure you have jcenter() in your project gradle.

Important Notes

Remember to set android:id for me.henrytao.smoothappbarlayout.SmoothAppBarLayout in layout file so that it can call onSaveInstanceState and onRestoreInstanceState correctly. Otherwise, it won't work correctly with onOrientationChanged.
Remember to set android:minHeight for me.henrytao.smoothappbarlayout.SmoothAppBarLayout in layout file if you use ViewPager.
clipToPadding in RecyclerView won't work. You have to set HeaderHolder in apdater and it has to be placed at index 0.

Usage

Super easy! Just need to do 3 steps:

Change android.support.design.widget.AppBarLayout to me.henrytao.smoothappbarlayout.SmoothAppBarLayout and set android:id
Remove app:layout_behavior="@string/appbar_scrolling_view_behavior".
Add header to your NestedScrollView or RecyclerView.
