LayoutManager that fills all RecyclerView area

Question

I have a RecyclerView. I would like to achieve following (each circle is one RecyclerView item):

Each circle might have differing size.

I tried to use GridLayoutManager but it turns out that I need to provide a spanCount which is something does not fit my case.

Please check this link https://github.com/nex3z/FlowLayout. – Abhinav Suman Jan 27 '19 at 15:58 — Abhinav Suman, Jan 27 '19 at 15:58

For the RecycleView layouts in a grid form with different cell spans can be achieved by using the GridLayoutManager. You will find many tutorials in the internet about how to implement it.

GridLayoutManager  layoutManager = new GridLayoutManager(this, 6);

layoutManager.setSpanSizeLookup(new GridLayoutManager.SpanSizeLookup() {
    @Override
    public int getSpanSize(int position) {
        // Use whatever logic you need here to decide how 
        //  many columns to span for any given row position
        if (position % 2)
            return 3;
        else
            return 6;
    }
});

Then in onBindViewHolder update the LayoutParams.width of each view as you may require.

I also tried this earlier. This layout manager also required `spanCount` which problematic is because I do not know the count of both coloumns and rows. – Azizjon Kholmatov Jan 27 '19 at 13:41
getting Cannot resolve method 'setSpanSizeLookup(anonymous android.support.v7.widget.GridLayoutManager.SpanSizeLookup)` error. – Azizjon Kholmatov Jan 27 '19 at 14:16
I dont think that you can set `setSpanSizeLookup` for `StaggeredGridLayoutManager`. – Azizjon Kholmatov Jan 27 '19 at 14:23
Then for such case is better to use a GridLayoutManager, and update the views metrics when binding them. So use the lookup to specify how many columns a row must span, and the onBindViewHolder to update the individual views metrics to render accordingly the required columns area. – PerracoLabs Jan 27 '19 at 14:55
