How to set the height of an item row in GridLayoutManager

Question

My Recycler Item which inflate in onCreateViewHolder

Answer 1

sometime, getting size of inflate view in adapter return 0 or negative. another approach is get required size from out side the adapter, manipulate it and set it into view. in my case, another problem was size set effectless. so i set the size using layout parameter

here is setting my adapter in activity:

Display display = MainActivity.this.getWindowManager().getDefaultDisplay();
                    Point size = new Point();
                    display.getSize(size);
                    int  y = size.y;
                    y=(int)y/2;
 GridLayoutManager linearLayoutManager = new GridLayoutManager(MainActivity.this,2);
                    recyclerView.setLayoutManager(linearLayoutManager);
                    NewOrderAdapter newOrderAdapter=new NewOrderAdapter(MainActivity.this,arrayListname,arrayListimage,y);
                    recyclerView.setAdapter(newOrderAdapter);

and i set view size like this:

@Override
    public myviewholder onCreateViewHolder(ViewGroup viewGroup, int i) {
        View view = inflator.inflate(R.layout.new_order_row, viewGroup, false);
        GridLayoutManager.LayoutParams params = (GridLayoutManager.LayoutParams) view.getLayoutParams();
        params.height = ysize;
        view.setLayoutParams(params);
        myviewholder holder = new myviewholder(view);
        return holder;
    }

and dont forget to set a height to layout in your layout for initializatiin
