How to solve for viewpager : The specified child already has a parent. You must call removeView() on the child's parent first

Question

Into my project I am using viewpager with three tabs named History,Main,Map.Main activity contain Timer,stopwatch,etc

Answer 1

// if the child view to be added is already bound to a parent, then remove the child from the parent and then add again to the container.

if (v.getParent() != null) {
  ((ViewGroup) v.getParent()).removeView(v);
}
container.addView(v);
