I have implemented Navigation Drawer by Referring this tutorial and now what I want to do is to display swiping tabs inside a fragment. i.e. when i click on an item in navigation drawer, lets say the first one, it should display swiping tabs for that items.( I have 6 fragments in my list view.(likewise :- A,B,C,D,E,F). and I need 3 swapable tabs on my A Fragment.)
If the item1 is Events, when i click on it, then it should display swiping tabs.
But I am facing the following issues:-
How can I implement view pager inside fragment?
It is possible that a fragment extends a fragment.
when A fragment is extending a FragmentActivity, then in my main activity, code is showing an error saying "type mismatch", can't convert from A Fragment to fragment.

this is my deep.xml code :-

android:divider="@color/list_divider"

android:listSelector="@drawable/list_selector" />
</android.support.v4.widget.DrawerLayout>
This is my homefragment.xml code :-

</android.support.v4.view.ViewPager>
For error in step 7 "Type mismatch
make it:
and in case:
where declaration of mTabs variable
thanks
You must create a fragment with a custom layout that contains a ViewPager on it.
Follow these steps, it will guide in the entire process.
1. Create the layout to represent the ViewPager, name it fragment_main.xml
2. Create a fragment to hold the ViewPager declared on the XML above, name it MyFragment.java
As you can see, we declare the
TabHost
theViewPager
and other elements declared in the XML above. Also in this fragment we inflate the layout created before, and aTabAdapter
to handle all the tabs.As you can see, each tab calls a specific fragment. These fragments represent the content for each tab. So let's create them, they are very simple, and contains only a
TextView
.3. Create a fragment for the first tab content, name it PageOneFragment.java
This fragment will hold the content of the first tab. You can put anything inside this fragment, it will live separated from the other fragments and from the other tabs.
Here we inflate the xml layout pageone_fragment.xml inside the
onCreateView
method. We will create this xml layout in the next step.We must create the layout for this fragment as we mentioned before.
4. Create the layout for the PageOneFragment, name it pageone_fragment.xml
This is just a simple layout with a
TextView
to represent the content of the tab. You can build anything you want inside this layout, it will live separated from the other fragments and tabs.As we have two tabs, we have two fragments, one for each tab. So let's create the second fragment for the second tab content.
5. Create the fragment for the second tab content, name it PageTwoFragment.java
As you can see, we inflate a different layout on the
onCreateView
method, it's calledpagetwo_fragment.xml
. We will create it on the next step.And as we did before for the PageOneFragment, let's create the layout for the second fragment too, as we mentioned before.
6. Create the layout for the PageTwoFragment, name it pagetwo_fragment.xml
This is a simple layout with a single
TextView
, just to represent the content. You can build anything you want in here, it will live separated from the other fragments and tabs.7. Call this fragment from your
NavigationDrawer
If you want to call this fragment from your
NavigationDrawer
, inside theswitch
statement on your activity'sdisplayView(int position)
method, you should do this in one of yourcase
statements, for example.Here is the final result
A
ViewPager
running on a fragment, with two tabs each contains a unique fragment with a unique content.That's it.
Hope this helps you.
