Android Navigation Drawer can't click on one item

I have a really interesting problem with my Navigator menu.
I have no idea why... But I can click on any item from my menu, I don't want to say I click and nothing happened. I really want to say I can't click on any item, all my menu it's like a big image.
I've try to make a new project witch already have Navigation Drawer Activity, of course it works.. but when I've try to copy that code and put on mine.. I have the same problem and vice versa, I've try to put my code into a new project with Navigation Drawer Activity, but again... I can't click on any item.
Here it's one image with my aplication.
Here it's my Main Activity:
public class MainActivity extends Activity implements NavigationDrawerFragment.NavigationDrawerCallbacks, AdapterView.OnItemClickListener {

Please call addToBackStack(null) when you perform fragment transaction.
fragmentManager.beginTransaction()
.replace(R.id.mainContent, fragment)
.addToBackStack(null)
.commit();

Please update your OnCreateView() as below:
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
if (view != null) {
if (view.getParent() != null) {
((ViewGroup)view.getParent()).removeView(view);
}
return view;

use
pager.setOffscreenPageLimit(X);
where X is the count of the pages you want to save so the ViewPager wont rebuild them.

Action Button Not Showing Drawable in Action Bar

I am trying to get an action button to appear in my action bar, however I am only able to get the action overflow to show up instead of the drawable. Here is what I see.
Here is my menu_friends.xml source:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:binder="http://schemas.android.com/apk/res-auto" >
<!-- action_friends should appear as action button -->
<item android:id="#+id/action_friends"
android:icon="#drawable/ic_account_plus_grey600_24dp"
android:title="#string/menu_edit_friends_label"
binder:showAsAction="always" />
</menu>
Here is the fragment where I am inflating the menu:
public class FriendsFragment extends Fragment {
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
setHasOptionsMenu(true);
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_friends, container, false);
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
super.onCreateOptionsMenu(menu, inflater);
menu.clear();
inflater.inflate(R.menu.menu_friends, menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_friends:
navigateToEditFriends();
}
return super.onOptionsItemSelected(item);
}
private void navigateToEditFriends() {
Intent myIntent = new Intent(FriendsFragment.this.getActivity(), EditFriendsActivity.class);
startActivity(myIntent);
}
}
Here is my MainActivity code:
public class MainActivity extends FragmentActivity {
private static final String TAG = MainActivity.class.getSimpleName();
private PagerSlidingTabStrip tabs;
private ViewPager pager;
private MyPagerAdapter adapter;
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;

mDrawerList = (ListView) findViewById(R.id.left_drawer);
// set a custom shadow that overlays the menu_main content when the drawer opens
mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);
// Add items to the ListView
mDrawerList.setAdapter(new ArrayAdapter<String>(this, R.layout.drawer_list_item, mDrawerItems));
// Set the OnItemClickListener so something happens when a

mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
// Enable ActionBar app icon to behave as action to toggle the NavigationDrawer
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);

};

tabs = (PagerSlidingTabStrip) findViewById(R.id.tabs);
pager = (ViewPager) findViewById(R.id.pager);
adapter = new MyPagerAdapter(getSupportFragmentManager());
pager.setAdapter(adapter);

Any help on this would be greatly appreciated!

Put the setHasOptionsMenu() in your Fragments onCreate methode and not in onCreateView() methode. That should do the trick.

setIconified(false) force closes my app

Right now I have it not force closing but the keyboard pops up without the search box openning up, like in this picture:
My Search Fragment activity looks like:
public class Search extends Fragment implements SearchView.OnQueryTextListener, ReadJSONResult.OnArticleSelectedListener {
private ListView lv;
View v;
SearchView searchView;
private SearchView mSearchView;
private MenuItem mSearchMenuItem;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
//set layout here
v = inflater.inflate(R.layout.activity_search, container, false);
setHasOptionsMenu(true);
getActivity().setTitle("Search");
//get user information
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(getActivity());
String userName = prefs.getString("userName", null);
String userID = prefs.getString("userID", null);
//ActionBar actionBar = getActivity().getActionBar();
// Inflate the layout for this fragment
return v;
}
#Override
public void onCreateOptionsMenu (Menu menu, MenuInflater inflater) {
// Inflate the menu; this adds items to the action bar if it is present.
searchView = (SearchView) menu.findItem(R.id.menu_search2).getActionView();
searchView.setOnQueryTextListener(this);
searchView.setIconified(false);
}
public boolean onQueryTextSubmit (String query) {
//toast query
//make json variables to fill
// url to make request
String url = "myURL";
try {
query = URLEncoder.encode(query, "UTF-8");
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
String jsonUrl = url + query;
//todo: get json
ReadJSONResult task = new ReadJSONResult(getActivity());
task.setOnArticleSelectedListener(this);
task.execute(jsonUrl);
return false;
}
#Override
public boolean onQueryTextChange(String newText) {
// TODO Auto-generated method stub
return false;
}
#Override
public void onArticleSelected(String b, String brewery){
//code to execute on click
Fragment Fragment_one;
FragmentManager man= getFragmentManager();
FragmentTransaction tran = man.beginTransaction();
Fragment_one = new BeerPage();
final Bundle bundle = new Bundle();
bundle.putString("beerIDSent", b);
bundle.putString("breweryIDSent", brewery);
Fragment_one.setArguments(bundle);
tran.replace(R.id.main, Fragment_one);//tran.
tran.addToBackStack(null);
tran.commit();
}
}
my android action bar menu xml is:

looks like here
searchView.setIconified(false);
"searchView" has not been initialized properly yet, because before you create the field, but didn't assign any view for it:
SearchView searchView;
So in your onCreateView you should find your View by Id first before calling methods of searchView:
searchView = (SearchView) findViewById(R.id.the_view_id_here);
