If you need to handle the action more specifically with the back button you can use the following method   view setFocusableInTouchMode true   view requestFocus    view setOnKeyListener new View OnKeyListener          Override     public boolean onKey View v  int keyCode  KeyEvent event            if  keyCode    KeyEvent KEYCODE BACK                         onCloseFragment                return true            else               return false

Try this   ft addToBackStack null        ft is FragmentTransaction   So  when you press back-key  the current activity  which holds multiple fragments  will load previous fragment rather than finishing itself

From Fragment A  to go to B  replace A with B and use addToBackstack   before commit     Now From Fragment B  to go to C  first use popBackStackImmediate    this will bring back A  Now replace A with C  just like the first transaction

In your Fragments onCreateView      you can remove a view by calling container removeView view    So if you want to remove the fragment  then view should be the return value of onCreateView    for example      public View onCreateView               final View view   inflater inflate R layout your fragments layout container false             Do something         finishButton setOnClickListener new View OnClickListener                 Override             public void onClick View v                   container removeView view                                     return view
