}</pre> </div>
 
   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));</pre> </div>
 
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
    }
}
