I had this problem and couldn t solve it in Java code   The problem was with my xml   I was trying to add a textView to a container  but had wrapped the textView inside a LinearLayout   This was the original xml file    x000D   x000D   lt  xml version  1 0  encoding  utf-8   gt  x000D   lt LinearLayout xmlns android  http   schemas android com apk res android  x000D      android orientation  vertical  x000D      android layout width  match parent  x000D      android layout height  match parent  gt  x000D       x000D       lt TextView xmlns android  http   schemas android com apk res android  x000D          android id   android id text1  x000D          android layout width  match parent  x000D          android layout height  wrap content  x000D          android textAppearance   android attr textAppearanceListItemSmall  x000D          android gravity  center vertical  x000D          android paddingLeft  16dp  x000D          android paddingRight  16dp  x000D          android textColor   fff  x000D          android background   android attr activatedBackgroundIndicator  x000D          android minHeight   android attr listPreferredItemHeightSmall   gt  x000D   x000D   lt  LinearLayout gt  x000D   x000D   x000D    Now with the LinearLayout removed    x000D   x000D   lt TextView xmlns android  http   schemas android com apk res android  x000D          android id   android id text1  x000D          android layout width  match parent  x000D          android layout height  wrap content  x000D          android textAppearance   android attr textAppearanceListItemSmall  x000D          android gravity  center vertical  x000D          android paddingLeft  16dp  x000D          android paddingRight  16dp  x000D          android textColor   fff  x000D          android background   android attr activatedBackgroundIndicator  x000D          android minHeight   android attr listPreferredItemHeightSmall   gt  x000D   x000D   x000D    This didn t seem like much to me but it did the trick  and I didn t change my Java code at all   It was all in the xml

Sorry to post to an old question but I was able to fix it using a totally different solution  I was getting this exception but I changed the first line of my onCreatView override from this   View result   inflater inflate R layout customer layout  container        to this   View result   inflater inflate R layout customer layout  container  false     I have no idea why but using the override that accepts the boolean as the third param fixed it   I think it tells the Fragment and or Activity not to use the  container  as the parent of the newly-created View

You are adding a View into a layout  but the View already is in another layout  A View can t be in more than one place

When you override OnCreateView in your RouteSearchFragment class  do you have the   if view    null        return view       code segment   If so  removing the return statement should solve your problem   You can keep the code and return the view if you don t want to regenerate view data  and onDestroyView   method you remove this view from its parent like so        Override     public void onDestroyView             super onDestroyView            if  view    null                ViewGroup parent    ViewGroup  view getParent                if  parent    null                    parent removeAllViews

I had this code in a fragment and it was crashing if I try to come back to this fragment  if  mRootView    null        mRootView   inflater inflate R layout fragment main  container  false        after gathering the answers on this thread  I realised that mRootView s parent still have mRootView as child  So  this was my fix   if  mRootView    null        mRootView   inflater inflate R layout fragment main  container  false     else         ViewGroup  mRootView getParent    removeView mRootView       hope this helps

It also happens when the view returned by onCreateView   isn t the view that was inflated   Example   View rootView   inflater inflate R layout my fragment  container  false    TextView textView    TextView  rootView findViewById R id text view   textView setText  Some text      return textView      Fix   return rootView    Instead of   return textView     or whatever you returned

in your xml file you should set layout width and layout height from wrap content to match parent  it s fixed for me    lt FrameLayout         android id    id container          android layout width  match parent          android layout height  match parent    gt

I solved it by setting attachToRoot of inflater inflate   to false   public View onCreateView LayoutInflater inflater  ViewGroup container  Bundle savedInstanceState        View view   inflater inflate R layout fragment overview  container  false       return view
