android.view.InflateException: Binary XML file line: Error inflating class fragment

Question

I'm trying to make an app that contains an ActionBar with 3 tabs: "Map", "Destinatiosn" and "About Us". Basically i'm using ViewPager as main layout and for individual pager views i use Fragments.

activity_main.xml

<android.support.v4.view.ViewPager xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent">
</android.support.v4.view.ViewPager>

MainActivity.java

public class MainActivity extends FragmentActivity implements ActionBar.TabListener {   
private ViewPager viewPager;
private TabsPagerAdapter mAdapter;
private ActionBar actionBar;
// Tab titles
private String[] tabs = { "Maps", "Destinations", "About us" };

/***************************************************************************************
 * 
 */
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    // Initialization
    //tabs = getResources().getStringArray(R.array.tabs_titles);
    viewPager = (ViewPager) findViewById(R.id.pager);
    actionBar = getActionBar();
    mAdapter = new TabsPagerAdapter(getSupportFragmentManager());

    viewPager.setAdapter(mAdapter);
    //actionBar.setHomeButtonEnabled(false);
    actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);        

    // Adding Tabs
    for (String tab_name : tabs) {
        actionBar.addTab(actionBar.newTab().setText(tab_name).setTabListener(this));
    }

    /**
     * on swiping the viewpager make respective tab selected
     * */
    viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {

        @Override
        public void onPageSelected(int position) {
            // on changing the page
            // make respected tab selected
            actionBar.setSelectedNavigationItem(position);
        }

        @Override
        public void onPageScrolled(int arg0, float arg1, int arg2) {
        }

        @Override
        public void onPageScrollStateChanged(int arg0) {
        }
    });
}

/***************************************************************************************
 * 
 */
@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

/***************************************************************************************
 * 
 */
@Override
public void onTabReselected(Tab tab, android.app.FragmentTransaction arg1) {


}

/***************************************************************************************
 * 
 */
@Override
public void onTabSelected(Tab tab, android.app.FragmentTransaction arg1) {
    // on tab selected
    // show respected fragment view
    viewPager.setCurrentItem(tab.getPosition());

}

/***************************************************************************************
 * 
 */
@Override
public void onTabUnselected(Tab tab, android.app.FragmentTransaction arg1) {
    // TODO Auto-generated method stub

}

}

I am creating a FragmentPagerAdapter class to provide views to tab fragments.

public class TabsPagerAdapter extends FragmentPagerAdapter {

public TabsPagerAdapter(FragmentManager fm) {
    super(fm);
}

@Override
public Fragment getItem(int index) {
    switch (index) {
    case 0:
        // Map fragment activity
        return new MapFragment();
    case 1:
        // Destinations fragment activity
        return new DestinationsFragment();
    case 2:
        // About Us fragment activity
        return new AboutUsFragment();
    }

    return null;
}

@Override
public int getCount() {
    // get item count - equal to number of tabs
    return 3;
}

}

Every one of the items have a layout file with his activity class.

Map

fragment_map Layout

<LinearLayout 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"
android:orientation="vertical" >

<fragment
    android:id="@+id/map"
    android:name="com.google.android.gms.maps.SupportMapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

</LinearLayout>

MapFragment class

public class MapFragment extends Fragment {
GoogleMap mapa;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {    

try{
    if(mapa == null){
        mapa = ((SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.map)).getMap(); 
    }             
    View rootView = inflater.inflate(R.layout.fragment_map, container, false);          
    return rootView;
}catch(Exception e){
    View rootView = inflater.inflate(R.layout.fragment_map, container, false);

    e.printStackTrace();
    return rootView;
}

} }

Destinations (just a Relative Layout with a Text view for now)

Layout

        <?xml version="1.0" encoding="utf-8"?>
        <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"
        android:background="#ff8400" >

            <TextView 
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:gravity="center"
                android:text="Destinations Screen"
                android:textSize="20sp"
                android:layout_centerInParent="true"/>
        </RelativeLayout>

class

public class DestinationsFragment extends Fragment {

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {


        Log.d("", "CESAR");
        View rootView = inflater.inflate(R.layout.fragment_destinations, container, false);

        return rootView;
    }
}

About Us (just a Relative Layout with a Text view for now)

layout

        <?xml version="1.0" encoding="utf-8"?>
        <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical"
            android:background="#17df0d">

        <TextView android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:gravity="center"
            android:text="Diseñar la pantalla de About Us"
            android:textSize="20sp"
            android:layout_centerInParent="true"/>

        </RelativeLayout>

class

        public class AboutUsFragment extends Fragment {

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {

        View rootView = inflater.inflate(R.layout.fragment_about_us, container, false);

        return rootView;
     }
     }

The problem is that when I change from tab "About Us" to any other tab, the app stops working and crashes. But this doesn't happen when i change from tab "Destinations" to the tab of "Map" and backwards. This error came when I added the MapFragment, before that, the map layout was just a RelativeLayout with a text view and worked well. The Map works.

You can't use that `fragment` tag in the xml layout(*fragment_map Layout*) if it's going to be the layout of another fragment. Instead use the `MapView` class. — user, Apr 10 '14 at 04:50

Check out Android, google maps fragment and viewpager - Error inflating class fragment

I am still working on implementing that solution, but it seems viable.
