我试图从一个片段移动到另一个片段.它在片段事务期间显示以下错误 -

    java.lang.IllegalArgumentException: No view found for id 0x1020002 (android:id/content) for fragment PhotosFragment2{41a57218 #3 id=0x1020002}

下面是类.我使用了以下代码进行片段事务

Fragment fragment = new PhotosFragment2();

                        FragmentTransaction fragmentTransaction = getFragmentManager().beginTransaction();
                        fragmentTransaction.replace(android.R.id.content, fragment);
                        fragmentTransaction.commit();

PhotosFragment.java

   public class PhotosFragment extends Fragment {
        private FragmentActivity myContext;
        @Override
        public void onAttach(Activity activity) {
            myContext = (FragmentActivity) activity;
            super.onAttach(activity);
        } …
