How can I make my GridView images have different sizes

The way I recommend it is to use the RecyclerView along with StaggeredGridLayoutManager .

You will have something like:

RecyclerView recycler = (RecyclerView) findViewById(R.id.recycler_view);

StaggeredGridLayoutManager staggeredLayoutManager =
        new StaggeredGridLayoutManager(2, StaggeredGridLayoutManager.VERTICAL);

recycler.setLayoutManager(staggeredLayoutManager);

Where the first parameter of StaggeredGridLayoutManager is the number of columns.

Of course, you can configure the strategy to fill in gaps.

Then you can use the setGapStrategy method with one of these constants:

GAP_HANDLING_MOVE_ITEMS_BETWEEN_SPANS - Não tem documentação, mas ele provavelmente move os itens para ocupar os espaços
GAP_HANDLING_LAZY - Só ocupa os gaps quando houver scroll
GAP_HANDLING_NONE - Não faz nada, deixa o gap

Another question is spans , in LayoutParams of the list item, you can define whether the item uses all spans or not, that is, whether it occupies the entire row or not.

Then just use it inside your Adapter o LayoutParams.setFullSpan(boolean) .

Of course you will have to implement a RecyclerView.Adapter , which is slightly different from implementing BaseAdapter for example.
