android - Check if view element is added to layout or not programmatically -

in fragment class, add child view element programmatically layout conditionally :

linearlayout child = (linearlayout) inflater.inflate(r.layout.child_view, null);  layoutparams params = new layoutparams(layoutparams.wrap_content,100);  container.addview(child, params); 

since above code run conditionally, so, @ point, i check if child view has added or not, how make checking programmatically?

i think can use

findviewbyid(your_view_id)  

method: if result null view not exists, otherwise view present
