The specified child already has a parent. You must call removeView() on the child's parent first (Android)
The error message says what You should do.
// TEXTVIEW
if(tv.getParent() != null) {
((ViewGroup)tv.getParent()).removeView(tv); // <- fix
}
layout.addView(tv); // <========== ERROR IN THIS LINE DURING 2ND RUN
// EDITTEXT
simply pass the argument
attachtoroot = false
View view = inflater.inflate(R.layout.child_layout_to_merge, parent_layout, false);
I came here on searching the error with my recyclerview but the solution didn't work (obviously). I have written the cause and the solution for it in case of recyclerview. Hope it helps someone.
The error is caused if in the onCreateViewHolder()
the following method is followed:
layoutInflater = LayoutInflater.from(context);
return new VH(layoutInflater.inflate(R.layout.single_row, parent));
Instead it should be
return new VH(layoutInflater.inflate(R.layout.single_row, null));
