/*** Add Menu */@ Override public boolean onCreateOptionsMenu (menu Menu) {MenuInflater inflater = getMenuInflater (); inflater. inflate (R. menu. menu, menu); return super. onCreateOptionsMenu (menu);}/*** solve the ActionBar problem */public void setOverflowMenuQues () {ViewConfiguration viewConfiguration = ViewConfiguration. get (this); try {Field field = ViewConfiguration. class. getDeclaredField ("sHasPermanentMenuKey"); field. setAccessible (true); field. setBoolean (viewConfiguration, false);} catch (Exception e) {e. printStackTrace ();}}
