hamburger ne fonctionne pas lorsque je clique. Je dois faire glisser pour le menu

Question

Ceci est l'activité principale où j'ai mis en œuvre le tiroir et la barre d'outils. J'ai essayé toutes les solutions possibles sur la pile. Je ne l'ai pas utilisé l'image du hamburger j'ai créé la vue de la navigation et ajouté dans mon xml:

public class NavigationMenu extends AppCompatActivity { 
    DrawerLayout drawerLayout; 
    Toolbar toolbar; 
    ActionBarDrawerToggle actionBarDrawerToggle; 
    FragmentTransaction fragmentTransaction; 
    NavigationView navigationView; 
    RoundImage roundedImage; 
    ImageView profileImage; 
    TextView uname,mail; 

    private SQLiteHandler db; 
    private SessionManager session; 

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

     toolbar = (Toolbar)findViewById(R.id.toolbar); 
     setSupportActionBar(toolbar); 
     getSupportActionBar().setDisplayHomeAsUpEnabled(true); 

     getSupportActionBar().setHomeButtonEnabled(true); 

     /* Setting drawer in menu*/ 
     drawerLayout = (DrawerLayout)findViewById(R.id.drawer_layout); 
     actionBarDrawerToggle = new ActionBarDrawerToggle(this,drawerLayout,R.string.drawer_open,R.string.drawer_close); 

     drawerLayout.setDrawerListener(actionBarDrawerToggle); 
     actionBarDrawerToggle.setDrawerIndicatorEnabled(true); 
     actionBarDrawerToggle.syncState(); 

     fragmentTransaction = getSupportFragmentManager().beginTransaction(); 
     fragmentTransaction.add(R.id.main_container,new HomeFragment()); 
     fragmentTransaction.commit(); 

     /* Accessing database getApplicationContext(*/ 
     db = new SQLiteHandler(this); 

     HashMap<String,String> user = db.getUserDetails(); 

     String id = user.get("id"); 
     String name = user.get("name"); 
     String email = user.get("email"); 

     Log.d("Soulsystem", name); 
     Log.d("Soulsystem", email); 

     /*Access navigation header here to set name and to call the attributes of header*/ 
     NavigationView navigationView = (NavigationView)findViewById(R.id.navigation_view); 
     View header = navigationView.getHeaderView(0); 

     uname = (TextView)header.findViewById(R.id.rahul); 
      uname.setText(name); 
     AppController.getInstance().setClientConsultancyDetails(id,name,email); 

     profileImage = (ImageView)header.findViewById(R.id.navigation_view_Image); 
     profileImage.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       profile(); 
      } 
     }); 

     // session manager 
     session = new SessionManager(getApplicationContext()); 

     if (!session.isLoggedIn()) { 
      logoutUser(); 
     } 

     navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() { 
      @Override 
      public boolean onNavigationItemSelected(MenuItem item) { 

       switch (item.getItemId()){ 

        case R.id.contact: 
         contact(); 
         break; 

        case R.id.logout: 
         logoutUser(); 
         /* item.setChecked(true); 
         drawerLayout.closeDrawers();*/ 
         break; 
       } 
       return true; 
      } 
     }); 
    } 
    protected void onPostCreate(@Nullable Bundle savedInstanceState) { 
     actionBarDrawerToggle.syncState(); 
     super.onPostCreate(savedInstanceState); 
    } 

    private void logoutUser() { 
     session.setLogin(false); 

     db.deleteUsers(); 
     Intent intent = new Intent(NavigationMenu.this, MainActivity.class); 
     startActivity(intent); 
    } 

    //call to Profile image fragment 
    private void profile(){ 
     Log.d("NavigationMenu", "In profile Image view"); 
     fragmentTransaction = getSupportFragmentManager().beginTransaction(); 
     fragmentTransaction.replace(R.id.main_container, new ClientProfile()); 
     fragmentTransaction.commit(); 
     drawerLayout.closeDrawers(); 
    } 

    //call to Contact image fragment 
    private void contact(){ 
     Log.d("NavigationMenu", "In profile Image view"); 
     fragmentTransaction = getSupportFragmentManager().beginTransaction(); 
     fragmentTransaction.replace(R.id.main_container, new Contact()); 
     fragmentTransaction.commit(); 
     drawerLayout.closeDrawers(); 
    } 
    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     // Inflate the menu; this adds items to the action bar if it is present. 
     getMenuInflater().inflate(R.menu.drawe_menu, menu); 
     return false; 
    } 

    @Override 
    public boolean onPrepareOptionsMenu(Menu menu) { 
     MenuItem item= menu.findItem(R.menu.drawe_menu); 
     item.setVisible(false); 
     super.onPrepareOptionsMenu(menu); 
     return true; 
    } 

    @Override 
    public boolean onOptionsItemSelected(MenuItem item) { 
     if (actionBarDrawerToggle.onOptionsItemSelected(item)) { 
      return true; 
     } 
     return super.onOptionsItemSelected(item); 
    } 
}

Essayez d'écouter la barre d'outils

toolbar.setNavigationOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) 
       drawerLayout.openDrawer(GravityCompat.START); 
      } 
     } 
    });
