在片段内添加带有活动的标签主机

Question

Good day. I have some problem. I have app with listview at left and detail view at right. In right view I have a fragment with tab host. But I also want to add activities for all tabs. For example: I have clients list at left. At right I have tabs: "clients comments", "clients photos", "clients Info" In clients comments I need in activity with comments for this client, and with possibility to add new comment. I have already made a list view and detail, but I have problems with integration tab hosts into it. So what I have. Here My code of detail fragment

 public class ItemDetailFragment extends Fragment {

        public static final String ARG_ITEM_ID = "item_id";

        DummyContent.DummyItem mItem;
        private Activity lo_parentAct;



        public ItemDetailFragment() {
        }

        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            if (getArguments().containsKey(ARG_ITEM_ID)) {
                mItem = DummyContent.ITEM_MAP.get(getArguments().getString(ARG_ITEM_ID));
            }
        }

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                Bundle savedInstanceState) {
            View rootView = inflater.inflate(R.layout.fragment_item_detail, container, false);
            if (mItem != null) {
                Intent lv_intent;
            //    ((TextView) rootView.findViewById(R.id.item_detail)).setText(mItem.content);
                TabHost tabHost=(TabHost)rootView.findViewById(R.id.tabHost);
                tabHost.setup();

                TabSpec spec1=tabHost.newTabSpec("Tab 1");
                spec1.setIndicator("Общая информация");
                lo_parentAct = this.getActivity();
                lv_intent = new Intent(lo_parentAct, ClientInfoActivity.class);

                TabSpec spec2=tabHost.newTabSpec("Tab 2");
                spec2.setIndicator("Заметки");
                lv_intent = new Intent(lo_parentAct, ClientCommentsActivity.class);

                TabSpec spec3=tabHost.newTabSpec("Tab 3");
                spec3.setIndicator("Фото");
                lv_intent = new Intent(lo_parentAct, ClientPhotosActivity.class);


                tabHost.addTab(spec1);
                tabHost.addTab(spec2);
                tabHost.addTab(spec3);

            }
            return rootView;
        }
    }

An the layout

    <TabHost android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:id="@+id/tabHost"

            android:text="This is tab1"
            android:id="@+id/txt1"
            />    

     </LinearLayout>

     <LinearLayout

Answer 1

add tab host with activities inside fragment

You can't put activities into fragments! As I understand - you want to put TabActivity (wich is deprecated) with different activities into your main activity's root Fragment - this way is absolutely wrong.

One way to implement what you need is:

1. create one FragmentActivity .
2. put TabWidget into root layout of your FragmentActivity .
3. then put different Fragments into you TabWidget's tabs.

You can look at my similar answer with code examples into another theme (link) .
