Using ActionBarSherlock With the New SupportMapFragment

Question

I am looking at using ActionbarSherlock but have one query that's holding me back.

So my application needs to be fully backwards compatible to API Level 7.

I need to implement the new Google Maps in my application and to do that I need to use the SupportMapFragment class.

** My Question **

Is it possible to use the SupportMapFragment class alongside ActionBarSherlock?

Thanks in advance

EDIT

I have downloaded and had a look at the library. The only changes to the extended Fragments I can see are very simple and the same for all of them.

Do you think I could add support myself?

here is how they are supported.

package com.actionbarsherlock.app;  import android.app.Activity; import android.support.v4.app.DialogFragment; import com.actionbarsherlock.internal.view.menu.MenuItemWrapper; import com.actionbarsherlock.internal.view.menu.MenuWrapper; import com.actionbarsherlock.view.Menu; import com.actionbarsherlock.view.MenuInflater; import com.actionbarsherlock.view.MenuItem;  import static com.actionbarsherlock.app.SherlockFragmentActivity.OnCreateOptionsMenuListener; import static com.actionbarsherlock.app.SherlockFragmentActivity.OnOptionsItemSelectedListener; import static com.actionbarsherlock.app.SherlockFragmentActivity.OnPrepareOptionsMenuListener;  public class SherlockDialogFragment extends DialogFragment implements OnCreateOptionsMenuListener, OnPrepareOptionsMenuListener, OnOptionsItemSelectedListener {     private SherlockFragmentActivity mActivity;  public SherlockFragmentActivity getSherlockActivity() {     return mActivity; }  @Override public void onAttach(Activity activity) {     if (!(activity instanceof SherlockFragmentActivity)) {         throw new IllegalStateException(getClass().getSimpleName() + " must be attached to a SherlockFragmentActivity.");     }     mActivity = (SherlockFragmentActivity)activity;      super.onAttach(activity); }  @Override public void onDetach() {     mActivity = null;     super.onDetach(); }  @Override public final void onCreateOptionsMenu(android.view.Menu menu, android.view.MenuInflater inflater) {     onCreateOptionsMenu(new MenuWrapper(menu), mActivity.getSupportMenuInflater()); }  @Override public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {     //Nothing to see here. }  @Override public final void onPrepareOptionsMenu(android.view.Menu menu) {     onPrepareOptionsMenu(new MenuWrapper(menu)); }  @Override public void onPrepareOptionsMenu(Menu menu) {     //Nothing to see here. }  @Override public final boolean onOptionsItemSelected(android.view.MenuItem item) {     return onOptionsItemSelected(new MenuItemWrapper(item)); }  @Override public boolean onOptionsItemSelected(MenuItem item) {     //Nothing to see here.     return false; } 

}

It all works like a charm, mainly thanks to Jake's great work on ActionBarSherlock

Here are the steps I followed:

1. Create a SherlockMapFragment class in your actiobarsherlock library project. I simply made a copy of SherlockFragment because I also needed support for setHasOptionsMenu(true)
2. The activity extends SherlockFragmentActivity (as usual)
3. The fragment extends the newly created SherlockMapFragment
4. ActionBarSherlock requires the new google-play-services_lib library
5. Your project requires the ActionBarSherlock library. No need to include the google-play-services again, or to build against Google API.
6. As mentionned by Graham, you have to drop support for API 7 devices: <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="17" />

And here's some code for a more detailed explanation:

SherlockMapFragment

package com.actionbarsherlock.app;  import com.actionbarsherlock.internal.view.menu.MenuItemWrapper; import com.actionbarsherlock.internal.view.menu.MenuWrapper; import com.actionbarsherlock.view.Menu; import com.actionbarsherlock.view.MenuInflater; import com.actionbarsherlock.view.MenuItem; import com.google.android.gms.maps.SupportMapFragment;  import android.app.Activity; import android.support.v4.app.Watson.OnCreateOptionsMenuListener; import android.support.v4.app.Watson.OnOptionsItemSelectedListener; import android.support.v4.app.Watson.OnPrepareOptionsMenuListener;  public class SherlockMapFragment extends SupportMapFragment         implements OnCreateOptionsMenuListener,         OnPrepareOptionsMenuListener,         OnOptionsItemSelectedListener {     private SherlockFragmentActivity mActivity;      public SherlockFragmentActivity getSherlockActivity() {         return mActivity;     }      @Override     public void onAttach(Activity activity) {         if (!(activity instanceof SherlockFragmentActivity)) {             throw new IllegalStateException(getClass().getSimpleName()                     + " must be attached to a SherlockFragmentActivity.");         }         mActivity = (SherlockFragmentActivity) activity;          super.onAttach(activity);     }      @Override     public void onDetach() {         mActivity = null;         super.onDetach();     }      @Override     public final void onCreateOptionsMenu(android.view.Menu menu, android.view.MenuInflater inflater) {         onCreateOptionsMenu(new MenuWrapper(menu), mActivity.getSupportMenuInflater());     }      @Override     public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {         // Nothing to see here.     }      @Override     public final void onPrepareOptionsMenu(android.view.Menu menu) {         onPrepareOptionsMenu(new MenuWrapper(menu));     }      @Override     public void onPrepareOptionsMenu(Menu menu) {         // Nothing to see here.     }      @Override     public final boolean onOptionsItemSelected(android.view.MenuItem item) {         return onOptionsItemSelected(new MenuItemWrapper(item));     }      @Override     public boolean onOptionsItemSelected(MenuItem item) {         // Nothing to see here.         return false;     } } 

The activity:

public class MainActivity extends SherlockFragmentActivity {     @Override     public void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.activity_main);     } } 

The activity XML layout:

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"     android:id="@+id/root"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:orientation="horizontal" >      <fragment         android:id="@+id/fragment_map"         android:name=".ui.fragments.MapFragment"         android:layout_width="match_parent"         android:layout_height="match_parent"         android:tag="tag_fragment_map" />      <fragment         android:id="@+id/fragment_help"         android:name=".ui.fragments.HelpFragment"         android:layout_width="0dp"         android:layout_height="match_parent"         android:tag="tag_fragment_help" /> </FrameLayout> 

The map fragment:

public class MapFragment extends SherlockMapFragment {     private GoogleMap mMap;     @Override     public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {         View root = super.onCreateView(inflater, container, savedInstanceState);         mMap = getMap();         return root;     } }

I heard that Jake is not going to do too much more to ABS as Google may be bringing out their own backward compatible ActionBar. I think if I remember correctly it was discussed in one of the Android related Google+ hangouts.

The new maps requires API level 8 onward so before even worrying about the actionbar you will run into problems if you must support API level 7.

My advice would be produce 2 layout files one for level 7 and and one for 8+. In the level 7 use the now old MapView although they are deprecating it, which for me shows how API level 7 is not necessarily worth considering as a target. In the 8+ layout use the new map system.

As for the actionbar, we are porting an app right now and have easily and successfully added a map to a ViewPager, by creating the Fragment programtically (rather than in XML). We have tested it on multiple devices.

We have also had no issues using the new map system as described in Google demos with ABS. We declared the fragment in an XML layout and set this as the content of the activity. The ActionBar displays as normal. The Activity is a SherlockFragmentActivity.
