Different (dynamic) items height in GridLayoutManager

GridLayoutManager will use a grid, and you can set some span, but not different heights for different cells.

What you want is a StaggeredGridLayoutManager. This will just put the items on the screen if they fit, leading to your needed result. You can also change the reordering behavior, if you want to, by using setGapStrategy.

It's really easy. You have to add this manager to RecycleView:

recyclerView.setLayoutManager(new StaggeredGridLayoutManager(mColumnCount, 1));

in my case it's look like this:

Context context = view.getContext();
RecyclerView recyclerView = (RecyclerView) view;

if (mColumnCount <= 1) {
    recyclerView.setLayoutManager(new LinearLayoutManager(context));
} else {
    recyclerView.setLayoutManager(new StaggeredGridLayoutManager(mColumnCount, 1));
}
recyclerView.setAdapter(new MyItemRecyclerViewAdapter(DummyContent.ITEMS, mListener));
