Android Studio Project using Support Library focused on get Google Maps 3 states behavior including background image parallax and toolbars animations.

In your module/project build.gradle file add

dependencies {
   ...
   implementation 'com.mahc.custombottomsheetbehavior:googlemaps-like:0.9.1'
}

[]

Wiki under construction but still with some info already, until I complete it you can take a look at the example (app module).

• activity_main.xml (is like a template)
• activity_main.java (you can see how to listen for states)
• styles.xml (just the line <style name="AppTheme.NoActionBar">)
• AndroidManifest.xml (just the line android:theme="@style/AppTheme.NoActionBar")

1. I took the code from BottomSheetBehavior.java from Support Library 23.4.0 and added one state for anchor mode, so now you have:
   STATE_HIDDEN
   STATE_COLLAPSED
   STATE_DRAGGING
   STATE_ANCHOR_POINT
   STATE_EXPANDED.
   
   

2. Created Behaviors for FAB, ToolBars and ImageView.

Spend more than 3 days looking snipet of code or stackoverflow answers about it with no luck.
