Android Navigation Drawer over the tabs

Question

I am using the new navigation drawer available from the support library. When using the drawer along with tabs, the drawer menu is getting displayed below the tabs as shown below. How can i make sure the drawer menu is shown on the tabs. (It should display the drawer menu as if there are no tabs)

Drawer menu without tabs

Drawer menu with tabs

Answer 1

You can hide View responsible for rendering tabs manualy:

public static void setActionBarNavigationVisibility(Activity activity, boolean visible) {
    // --- If the Tabs are BELOW ActionBar (narrow screens) --- 
    int actionViewResId = Resources.getSystem().getIdentifier("action_bar_container", "id", "android"); // @see http://stackoverflow.com/questions/20023483/how-to-get-actionbar-view
    View actionBarContainer = activity.findViewById(actionViewResId); // returns instance of com.android.internal.widget.ActionBarContainer (inaccessible)
    try {
        Field mTabContainerField = actionBarContainer.getClass().getDeclaredField("mTabContainer");
        if (mTabContainerField != null) {
            mTabContainerField.setAccessible(true);
            View mmTabContainer = (View) mTabContainerField.get(actionBarContainer);
            if (mmTabContainer != null)
                mmTabContainer.setVisibility(visible ? View.VISIBLE : View.GONE); // use GONE, so the mTabContainer below ActionBar does not take space in layout
        }
    } catch (Exception e) {
        // TODO handle exception
    }
}

Just call this method from your implementation of ActionBarDrawerToggle like this:

public void onDrawerSlide(View drawerView, float slideOffset) {
        super.onDrawerSlide(drawerView, slideOffset);
        if (slideOffset == 0) { // 0 = drawer is closed             
            setActionBarNavigationVisibility(activity, true); //show Tabs when Drawer is closed             
        }
    }

public void onDrawerStateChanged(int newState) {
        super.onDrawerStateChanged(newState);
        //hides Tabs right after Drawer starts opening
        if (DrawerLayout.STATE_DRAGGING == newState || DrawerLayout.STATE_SETTLING == newState) {
            setActionBarNavigationVisibility(activity, false);
        }
    }

---

This solution will work just fine, if you are using ActionBar.Tabs on narrow screen (Tabs are shown automatically BELOW ActionBar). But if you want to handle all other navigation scenarios (NavigationMode: List, CustomNavigationView, or Tabs are showing directly in ActionBar), the first method needs to handle all these possibilities:

public static void setActionBarNavigationVisibility(Activity activity, boolean visible) {
    try {
        /* 1. --- If the navigation items are showing in ActionBar directly. We have 3 options Spinner, Tabs, and CustomNav ---
         (When Tabs are showing BELOW ActionBar, is handled at the end) */
        int actionViewResId = Resources.getSystem().getIdentifier("action_bar", "id", "android"); // @see http://stackoverflow.com/questions/20023483/how-to-get-actionbar-view
        View actionBarView = activity.findViewById(actionViewResId); // returns instance of com.android.internal.widget.ActionBarView (inaccessible)
        if (actionBarView != null) {
            int visibility = visible ? View.VISIBLE : View.INVISIBLE; // not GONE, so it still takes space in ActionBar layout

            // handle tabs navigation
            Field mTabScrollViewField = actionBarView.getClass().getDeclaredField("mTabScrollView");
            if (mTabScrollViewField != null) {
                mTabScrollViewField.setAccessible(true);
                View mTabScrollView = (View) mTabScrollViewField.get(actionBarView); // instance of com.android.internal.widget.ScrollingTabContainerView (inaccessible)
                if (mTabScrollView != null)
                    mTabScrollView.setVisibility(visibility);
            }

            // handle Spinner navigation
            Field mSpinnerField = actionBarView.getClass().getDeclaredField("mSpinner"); // resp. mListNavLayout
            if (mSpinnerField != null) {
                mSpinnerField.setAccessible(true);
                View mSpinner = (View) mSpinnerField.get(actionBarView); // instance of android.widget.Spinner
                if (mSpinner != null)
                    mSpinner.setVisibility(visibility);
            }

            // handle Custom navigation
            Field mCustomNavViewField = actionBarView.getClass().getDeclaredField("mCustomNavView"); // resp. mListNavLayout
            if (mCustomNavViewField != null) {
                mCustomNavViewField.setAccessible(true);
                View mCustomNavView = (View) mCustomNavViewField.get(actionBarView);
                if (mCustomNavView != null)
                    mCustomNavView.setVisibility(visibility);
            }
        }
        // 2. --- If the Tabs are BELOW ActionBar (narrow screens) ---          
        ViewParent actionBarContainer = actionBarView.getParent(); // parent of ActionBarView is com.android.internal.widget.ActionBarContainer (inaccessible)
        Field mTabContainerField = actionBarContainer.getClass().getDeclaredField("mTabContainer");
        if (mTabContainerField != null) {
            mTabContainerField.setAccessible(true);
            View mmTabContainer = (View) mTabContainerField.get(actionBarContainer);
            if (mmTabContainer != null)
                mmTabContainer.setVisibility(visible ? View.VISIBLE : View.GONE); // now use GONE, so the mTabContainer below Actionbar does not take space in layout
        }

    } catch (Exception ex) {
        // TODO Handle exception...         
    }
}

Here is the solution I am using looks like(works perfectly): I am using frame layout to be able swap fragments and the tabbed layout is the tabs on the base fragment.

activity_main.xml

<android.support.v4.widget.DrawerLayout
    android:id="@+id/drawer_layout"
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <!--<include-->
    <!--android:id="@+id/toolbar"-->
    <!--layout="@layout/toolbar"/>-->
    <FrameLayout
        android:id="@+id/content_frame"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <LinearLayout

            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical">

            <android.support.design.widget.TabLayout
                android:id="@+id/sliding_tabs"
                android:layout_width="match_parent"
                scrol
                android:layout_height="wrap_content"/>

            <android.support.v4.view.ViewPager
                android:id="@+id/viewpager"
                android:layout_width="match_parent"
                android:layout_height="match_parent"/>
        </LinearLayout>
    </FrameLayout>

    <ListView
        android:id="@+id/navList"
        android:layout_width="200dp"
        android:layout_height="match_parent"
        android:layout_gravity="left|start"
        android:background="#ffeeeeee"/>

</android.support.v4.widget.DrawerLayout>

I am not sure about Action Bar tabs , but you can use Pager Tab Strip in combination of Navigation Drawer to get navigation model similar like Google Play Music , have a look at my post

Answer 4

Actionbar Navigaton Drawer and SwipeTabs cant be used simultaneously. You should implement Navigation Drawer using Actionbar and swipetabs by simple Tabhosts. You can use Tabhost for tabs and use fragments for inside view of each Tab. Fragments should be used via viewpager to provide scrolling/swiping effect. Connect tabs and viewpager with eachother through their methods

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >

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

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical" >

        <HorizontalScrollView
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:fillViewport="true"
            android:scrollbars="none" >

            <TabWidget
                android:id="@android:id/tabs"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content" >
            </TabWidget>
        </HorizontalScrollView>

        <FrameLayout
            android:id="@android:id/tabcontent"
            android:layout_width="match_parent"
            android:layout_height="match_parent" >

            <android.support.v4.view.ViewPager
                android:id="@+id/viewPager_home"
                android:layout_width="match_parent"
                android:layout_height="match_parent" />
        </FrameLayout>
    </LinearLayout>
</TabHost>

Answer 5

Create a separate fragment say TabsFragment and add the fragment inside the fragment container in your main activity.

The tabs can be added inside the tabs fragment with the following code.

private FragmentTabHost mTabHost;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    mTabHost = new FragmentTabHost(getActivity());
    mTabHost.setup(getActivity(), getChildFragmentManager(), R.id.fragment1);

    mTabHost.addTab(mTabHost.newTabSpec("TabA").setIndicator("TabA"),
           TabA.class, null);
    mTabHost.addTab(mTabHost.newTabSpec("TabB").setIndicator("TabB"),
            TabB.class, null);

    return mTabHost;
}

Here, TabA and TabB are separate fragments for the tabs. You can implement your functionality of the respective tabs in respective fragments. Reference : http://developer.android.com/reference/android/support/v4/app/FragmentTabHost.html

Answer 6

I believe it's too late since question was asked but still. If you are already using navigation drawer and want navigation tabs, include the two files in your project folder:

1) SlidingTabLayout.java http://developer.android.com/samples/SlidingTabsBasic/src/com.example.android.common/view/SlidingTabLayout.html

2) SlidingTabStrip.java http://developer.android.com/samples/SlidingTabsBasic/src/com.example.android.common/view/SlidingTabStrip.html

In the navigation drawer fragment, include the following:

private SlidingTabLayout mSlidingTabLayout;
    private  SamplePagerAdapter_tasks mPagerAdapter;
    private ViewPager mViewPager;

    public void onViewCreated(View view, Bundle savedInstanceState) {
        // BEGIN_INCLUDE (setup_viewpager)
        // Get the ViewPager and set it's PagerAdapter so that it can display items
        //fragment manager of a fragment,Return a private FragmentManager for placing and managing Fragments inside of this Fragment.

        mPagerAdapter = new SamplePagerAdapter_tasks(getChildFragmentManager(),Titles of Tabs(array of string),Numboftabs (integer));
        mViewPager = (ViewPager) view.findViewById(R.id.viewpager);
        mViewPager.setAdapter(mPagerAdapter);

        // Give the SlidingTabLayout the ViewPager, this must be done AFTER the ViewPager has had
        // it's PagerAdapter set.
        mSlidingTabLayout = (SlidingTabLayout) view.findViewById(R.id.sliding_tabs);
        mSlidingTabLayout.setDistributeEvenly(true); // this helps to all the tabs on screen to take equal spaces (eg. if 3 tabs each would take one-third of the total space on the screen)

        mSlidingTabLayout.setViewPager(mViewPager);

        // END_INCLUDE (setup_slidingtablayout)
    }

Hope it helps!!
