 NavigationView.OnNavigationItemSelectedListener {
  public DrawerLayout drawerLayout;
  public ActionBarDrawerToggle actionBarDrawerToggle;

@Override

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_search);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    drawerLayout=findViewById(R.id.drawer_layout);
    actionBarDrawerToggle=new 
    ActionBarDrawerToggle(this,drawerLayout,R.string.open_drawer,R.string.close_drawer);
    drawerLayout.addDrawerListener(actionBarDrawerToggle);
    actionBarDrawerToggle.syncState();
    NavigationView navigationView=(NavigationView) findViewById(R.id.nav_view);

    navigationView.setNavigationItemSelectedListener(this);
    navigationView.bringToFront();
    drawerLayout.requestLayout();

   @Override
   public boolean onOptionsItemSelected(@NonNull MenuItem item)
   {

     DrawerLayout drawerLayout=(DrawerLayout) findViewById(R.id.drawer_layout);
