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;
    }
}
