LinearLayout pa=(LinearLayout)la.getParent();
if(pa!=null){
Log.i(TAG,"removed view la parent====>");
pa.removeView(la);
mNetworkLayout.removeView(la);
}
this one works for me.
but u should know ur parent first
lets say ur child parent is linearLayout then cast the parent to
linearlayout of your child
LinearLayout ll=(LinearLayout)child.getParent();
if (ll ! =null){
ll.remove(child)
}
I am not sure if it works for you let me know
