Add this to you project-level build.gradle:

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

Add this to your module-level build.gradle:

dependencies {
  compile 'com.github.PierfrancescoSoffritti:ShrinkingImageLayout:0.4'
}

Usage

ShrinkingImageLayout is a simple FrameLayout with some extra functionalities.

Add the ViewGroup to your layout file:

<com.pierfrancescosoffritti.shrinkingimagelayout.ShrinkingImageLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/shrinking_image_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

Then set it up by calling this method:

shrinkingImageLayout.setupRecyclerView(new RecyclerView(this), new LinearLayoutManager(this), new Adapter(getData()));

the adapter must implement HeaderRecyclerViewAdapter

Extra

To add an header to the RecyclerView call this method:

shrinkingImageLayout.addCustomHeader(header);

Where header can be any View object.

Call this method to get a reference to the ImageView

shrinkingImageLayout.getImageView();

On API 21+ the ImageView automatically handles its Z animation when scrolled and touched.
