USAGE

compile the library in your build.gralde


allprojects {
    repositories {
        jcenter()
        maven { url "https://jitpack.io" }
    }
}


dependencies {
   compile 'com.github.githubwing:ByeBurger:1.2.0'
  compile 'com.android.support:design:25.0.0'

You only need to change the root view to CoordinatorLayout, And add one line code "app:layout_behavior" like the bottom into ANY view, Then your view hiding on scroll. Your titleBar can be Toolbar,LinearLayout and so on. Your NavigationView can be BottomNavigationView or TabLayout, or Any View you put in xml.

<android.support.design.widget.CoordinatorLayout>

  <Viewpager />
    <Toolbar
      app:layout_behavior="@string/bye_burger_title_behavior"
  />
  <BottomTab 
   android:layout_gravity="bottom"
   app:layout_behavior="@string/bye_burger_bottom_behavior"
  />      
  <FloatingActionButton
    app:layout_behavior="@string/bye_burger_float_behavior"
  />
</android.support.design.widget.CoordinatorLayout>
