Bye Burger~ this is a easy way to make your title or bottom navigation hiding on scroll like this

Bye, Bye Burger! What we learned from implementing the new Android Bottom Navigation

Hiding on scroll: We wanted to provide as much content as possible on our user’s screens. Consequently, we decided to make the navigation hide on scroll, thus making more room for the content area. Scrolling up makes the navigation fade back in.

Shifting navigation : The Material Design bottom bar comes with a very slick animation, which is referred to as the Shifting navigation — when navigating between destinations the selected section icon is enlarged, moving the unselected element to the back. Flipping through destinations on the nav bar thus feels a bit like browsing through a carousel. We decided to utilize this effect as it adds a playful note to switching sections, which we hoped would nudge our users into navigating to different areas in the app more often. Further, the animation plays a major part in our next point…

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'
