Measure child in GridLayoutManager

I'm trying to override measureChild in GridLayoutManager to use specific layout params in measurement. But GridLayoutManager has its own private implementation of measureChild:

private void measureChild(View view, int otherDirParentSpecMode, boolean alreadyMeasured)

If I override public measureChild in RecyclerView.LayoutManager:

@Override
public void measureChild(View child, int widthUsed, int heightUsed) {
    super.measureChild(child, widthUsed, heightUsed);
}

It will be never called.

Is it possible to measure children in GridLayoutManager?

The 2 methods have different signatures so you shouldn't have any problems overriding them. Depending on the parameters you specify for the function in your child class the appropriate super will be called.

However, you need to modify your child class that extends from GridLayoutManager to override all functions that use GridLayoutmanager's implementation of measureChild to be able use the other implementation.

To check which methods call measureChild inside GridLayoutManager you can look at the source

EDIT: Seems like the layoutChunk method derived from LinearLayoutManager is package private so in this case I suppose the only way is to extend RecyclerView.LayoutManager and copy the entire code of GridLayoutManager replacing the measureChild calls with your own replacement modifying the code appropriately
