title: Recyclerview - Overlap items bottom to top
body: <p>I have set the negative margin for items like this:-</p>
  
  <p><strong>ItemDecoration.java</strong></p>
  
  <pre><code>public class ItemDecorator extends RecyclerView.ItemDecoration {
      private final int mSpace;
  
      public ItemDecorator(int space) {
          this.mSpace = space;
      }
  
      @Override
      public void getItemOffsets(Rect outRect, View view, RecyclerView parent, RecyclerView.State state) {
          int position = parent.getChildAdapterPosition(view);
          if (position != 0)
              outRect.top = mSpace;
      }
  }
  </code></pre>
  
  <p><strong>MainActivity.java</strong></p>
  
  <pre><code>recyclerView.setLayoutManager(new LinearLayoutManager(this));
  recyclerView.addItemDecoration(new ItemDecorator(-80));
  </code></pre>
  
  <p>This causes top item to stack lowest and next item after the top item overlaps it. I want top item to overlap its next item and so on.</p>
