Custom navigation drawer list view

Hi i'm new to the android world and i generated a navigation drawer with the default template in android studio.I'm looking for a way to make section in my listview like this :![enter image description here][1]
How i want my listview to be : https://camo.githubusercontent.com/7043b4240e1be50bb68b3f101c1f9815c9be0f11/68747470733a2f2f7261772e6769746875622e636f6d2f6e656f6b7265652f4d6174657269616c4e617669676174696f6e4472617765722f6d61737465722f73637265656e312e6a7067
Here is the code of my fragment,i really don't know how to do this and i want to have the image on the top with the email like the photo with two section:
public class NavigationDrawerFragment extends Fragment {
private static final String STATE_SELECTED_POSITION = "selected_navigation_drawer_position";
private static final String PREF_USER_LEARNED_DRAWER = "navigation_drawer_learned";

i have to finish this to next week cause it's a project at school :(

You can customize the navigation drawer with the proper layout you need.
You can inflate any layout with in the drawer and make proper logic to implement.
You need to modify the method
onCreateView();
For a particular layout you can modify as -
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView= inflater.inflate(
R.layout.fragment_navigation_drawer_layout, container, false);
return rootView;
}
Here
fragment_navigation_drawer_layout
is the layout you want to set.

How to call NavigationDrawer.syncState() from Fragment?

I am attempting to use Kanytu's android-material-drawer-template to implement a Navigation Drawer that meets Google's material design guidelines. The issue I'm facing is: Upon selecting a fragment to transition to from the navigation drawer, the selected fragment will successfully replace the current fragment within the 'container' FrameLayout. However, the HomeAsUp Indicater will display a "Back" navigation arrow in the Toolbar, rather than the Hamburger Icon needed to open the Navigation Drawer.
From what I can gather, this is due to the ActionBarDrawerToggle becoming out of sync when the fragments are being swapped. Assuming this to be the issue (I'm open for suggestions), how could I call .syncState() within the NavigationActivity fragments on the current ActionBarDrawerToggle?
public class NavigationActivity extends ActionBarActivity implements NavigationDrawerCallbacks {
private Toolbar mToolbar;
private NavigationDrawerFragment mNavigationDrawerFragment;
#Override
protected void onCreate( #Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_navigation);
mToolbar = (Toolbar) findViewById(R.id.toolbar_actionbar);
if (mToolbar != null) {
setSupportActionBar(mToolbar);
getSupportActionBar().setDisplayShowHomeEnabled(true);
}
mNavigationDrawerFragment = (NavigationDrawerFragment) getFragmentManager().findFragmentById(R.id.fragment_drawer);
mNavigationDrawerFragment.setup(R.id.fragment_drawer, (DrawerLayout) findViewById(R.id.drawer), mToolbar);
if (findViewById(R.id.container) != null) {
// However, if we're being restored from a previous state,
// then we don't need to do anything and should return or else
// we could end up with overlapping fragments.
if (savedInstanceState != null) {
return;
}
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return super.onCreateOptionsMenu(menu);
}
#Override
public void onNavigationDrawerItemSelected(int position) {
Toast.makeText(this, "Menu item selected -> " + position, Toast.LENGTH_SHORT).show();
if (position == 0) {
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
// Replace whatever is in the fragment_container view with this fragment,
// and add the transaction to the back stack so the user can navigate back
transaction.replace(R.id.container, new UserFragment());
transaction.addToBackStack(null);
// Commit the transaction
transaction.commit();
mToolbar = (Toolbar) findViewById(R.id.toolbar_actionbar);
if (mToolbar != null) {
setSupportActionBar(mToolbar);
getSupportActionBar().setTitle(getString(R.string.user_profile_title));
}
}
if (position == 1) {
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
// Replace whatever is in the fragment_container view with this fragment,

You are missing setContentView. Your Fragment can not be added without a View hierarchy.
Your issue is possibly similar to this one.

ActionBar is not showing Title in Android

I want to implement Left & Right Side Slider Menu so I have set Right Side Slider in NavigationDrawerSlider which already have Left Side Slider by Default.
I am using ActionBarSherLock for this to support Application from Api 8. Slider is working fine but issue is that ActionBar is not showing Title.
Please help me to solve this issue. One more thing, When I Click on ImageView, It also fires ActionBarDrawerToggle. So, how to prevent this also ?
My Code:
public class MainActivity extends SherlockFragmentActivity {
private DrawerLayout mDrawerLayout;
private ListView mDrawerList_Left;
private ListView mDrawerList_Right;
private ActionBarDrawerToggle mDrawerToggle;
private ActionBar actionBar_Right;
private ArrayList<NavDrawerItem> navDrawerItems_Left;
private ArrayList<NavDrawerItem> navDrawerItems_Right;

I have figured out that It is not showing title because of
actionBar_Right = getSupportActionBar();
actionBar_Right.setCustomView(R.layout.right_menu);
actionBar_Right.setDisplayShowTitleEnabled(true);
actionBar_Right.setDisplayShowCustomEnabled(true);
What to do for this ?

For showing the title in the ActionBar setTitle must be overridden:
#Override
public void setTitle(CharSequence title)
{
this.title = title;
getSupportActionBar().setTitle(title);
}

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:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context=".MainActivity" >
<item android:id="#+id/menu_search2"
android:actionViewClass="android.widget.SearchView"

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);
