Question

In android UI can be created dynamically so is there a way to know if a child was created to a parent ?

For example, if i have a linear layout as a parent and i dynamically create a child button. Is there away to notify the parent ?

Answer 1

It’s simple – if you have LinearLayout name linearLayout1, the only why to add child to him is
by calling the linearLayout.addView(View child) method.
so, you know exactly when the child added: it’s can be only after this method called 🙂
example:

linearLayout1.addView(view);
