If your RecyclerView list item parent has "wrap_content" property, Recyclerview calculates the heights again and scrolls top.

There are two solutions:

  1. Set your height a constant value like this: layout_height="100dp"
  2. Use StaggeredGridLayoutManager like this:

    mRecyclerView.setLayoutManager(new StaggeredGridLayoutManager(1, StaggeredGridLayoutManager.VERTICAL));

The second solution is more efficient and I suggest this one
