Add view to specific row and column in GridLayout

Question

My final objective is to be able to drag a view and drop it into a grid-oriented layout (ie a layout that restricts the placement of these views to cells, instead of anywhere).

I'm trying to do that with GridLayout , as it seemed appropriate, but I am now doubting if it is possible to do what I want using it.

When handling the drop, I try to add views to the GridLayout as such:

            GridLayout.Spec row = GridLayout.spec(4);
            GridLayout.Spec column = GridLayout.spec(2);
            LayoutInflater inflater = LayoutInflater.from(gridLayout.getContext());
            gridLayout.addView(inflater.inflate(R.layout.my_view, null), new GridLayout.LayoutParams(row, column));

The view does get added to the GridLayout , but not to the right cell (which would be, for the code above, the cell on the 5th row, 3rd column).

How can I do this correctly? Should I try something else besides GridLayout ? GridLayout seemed appropriate because I also want to be able to place views with different sizes in it (ie views that would span more or less cells).

Thank you.

Edit: I am considering using a RelativeLayout and adding views to it like so:

RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(30, 40);
params.leftMargin = 50;
params.topMargin = 60;
relativeLayout.addView(myView, params);

This way, I can specify the exact coordinates (eg (50;60) ) of the view.

As i can see the api does not provide this functionality, but you can do the following:

you can set:

mGridLayout.setOrientation(GridLayout.HORIZONTAL);

or

mGridLayout.setOrientation(GridLayout.VERTICAL);

to organize how the

mGridLayout.addView(view)

adds the childs in the grid. Using the first method (default) the childs are filled by columns first, whereas the second by rows first
