In my fragment class, I add a child view element programmatically to my layout conditionally :
LinearLayout child = (LinearLayout) inflater.inflate(R.layout.
Sorry for late reply but you may try this alternative:
use container.getChildCount();
before adding and after adding a view. Like :
int x = container.getChildCount();
container.addView(child, params);
int y = container.getChildCount();
if(y > x)
Toast.makeText(context, "View Successfully Added!", Toas.LENGTH_SHORT).show();
