Children views are null after inflate

Okay so I do this (not actual code)

try {
    final View view = LayoutInflater.from(context).inflate(R.layout.ownComponent, null);
} catch (InflateExpection e) {
}

if (view != null) {
    // This child is null about 5/10 times!

    View child = view.findViewById(R.id.ownComponentChild);
}

I read that after inflate it is not guaranteed that child views are inflated, so what would be neat way to get callback when all childs are ready?

This seems to happen randomly so my only guess is that memory is getting low in this case, because I have to recreate so many UI components fast to get this reproduced.

Maybe I misunderstood what you're trying to do, but it seems like you're inflating a View and not a layout...

Try 

View view = LayoutInflater.from(context).inflate(R.layout.LAYOUT_THAT_HOLDS_ownComponent, this, true);

and then view will hold the entire layout, from which you can find the child by Id with 

view.findViewById(...);

Edit:

Hard to know if it's related as you didn't post enough code but try this: Get the View view out of the try/catch and put it as a class member. loose the final and cast the child.

example (assuming ownComponentChild is a FrameLayout):

FrameLayout child = (FrameLayout)view.findViewById(R.id.ownComponentChild);
