Change output Rect color in RecyclerView ItemDecoration - Android

Question

I have this method in ItemDecoration class for recyclerView -

@Override
public void getItemOffsets(Rect outRect, View view, RecyclerView parent,   RecyclerView.State state) {
        outRect.left = space;
        outRect.right = space;
        outRect.bottom = space;

        // Add top margin only for the first item to avoid double space between items
        if(parent.getChildPosition(view) == 0)
            outRect.top = space;
}

Is there any way to change the color of output outRect like redrawing it or something ?

@pskink how do i use onDraw method here. It would require rect size etc. right ? – Shanley

what if view.setBackground()? – Canova

did you read ItemDecoration javadocs? – Solecism

@Canova view.setBackground() sets color only to items, not to offset – Mountain

Answer 1

You could have a look at ItemDecoration documentation.

2 main things to know :

• getItemOffsets(...) will allow you to determine the space between your items with provided rect in params.
• onDraw(...) will allow you to draw whatever you can in that space you set in getItemOffsets(...). You can use a Drawable or simple provided Canvas, etc.

If it's still not clear enough, check this article. I explain how to build your custom ItemDecoration
