Greedo Layout for Android

A drop-in custom layout manager for Android RecyclerViews to layout a grid of photos while respecting their aspect ratios.

Setup

Download the latest release via Gradle:

repositories {
  maven {
 url 'https://github.com/500px/greedo-layout-for-android/raw/master/releases/' 
}
 
}
  dependencies {
  compile 'com.fivehundredpx:greedo-layout:1.1.0' 
}

Usage

See the sample project for a complete solution on how to use GreedoLayout. Below are the specific steps.

// Create an instance of the GreedoLayoutManager and pass it to the RecyclerView MyRecyclerAdapter recyclerAdapter = new MyRecyclerAdapter(this);
 GreedoLayoutManager layoutManager = new GreedoLayoutManager(recyclerAdapter);
  RecyclerView recyclerView = (RecyclerView)findViewById(R.id.recycler_view);
 recyclerView.setLayoutManager(layoutManager);
 recyclerView.setAdapter(recyclerAdapter);
  // Set the max row height in pixels layoutManager.setMaxRowHeight(300);
  // If you would like to add spacing between items (Note, MeasUtils is in the sample project) int spacing = MeasUtils.dpToPx(4, this);
 recyclerView.addItemDecoration(new GreedoSpacingItemDecoration(spacing));

And then, in your RecyclerView adapter, or some other class of your choosing, implement SizeCalculatorDelegate. This implementation got passed to the layout manager above.

public class MyRecyclerAdapter extends RecyclerView.Adapter<ViewHolder> implements SizeCalculatorDelegate {

  @Override
  public double aspectRatioForIndex(int index) {

// Return the aspect ratio of your image at the given index
  
}
 
}
