单击项上的导航抽屉不起作用

如何解决单击项上的导航抽屉不起作用

DrawerLayout cabinetLayout =（DrawerLayout）findViewById（R.id.mainTarget）; NavigationView navigationView = findViewById（R.id.nav_view）;

    drawerToggle=new ActionBarDrawerToggle(MainActivity.this,drawerLayout,toolbar,R.string.navigation_drawer_open,R.string.navigation_drawer_close);
    drawerLayout.addDrawerListener(drawerToggle);
    drawerToggle.syncState();

    getSupportActionBar().setdisplayHomeAsUpEnabled(true);
    getSupportActionBar().setHomeAsUpIndicator(R.drawable.ic_baseline_menu_24);
    getSupportActionBar().setHomeButtonEnabled(true);

// onClick项目不起作用 //我需要使用片段注销并加载图库

    navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener()  {
        @Override
        public boolean onNavigationItemSelected(@NonNull MenuItem item) {
            if (item.getItemId()==R.id.nav_logout){
                SharedPreferences sharedPreferences=getSharedPreferences("LoginData",Context.MODE_PRIVATE);
                SharedPreferences.Editor editor=sharedPreferences.edit();
                editor.remove("key1");
                editor.apply();
                editor.commit();

            }
            else   if (item.getItemId()==R.id.nav_gallery){
                FragmentTransaction fragmentTransaction=getSupportFragmentManager().beginTransaction();
                fragmentTransaction.replace(R.id.mainTarget,SupportFrag2.newInstance("gallery"));
                fragmentTransaction.commit();
            }
            else   if (item.getItemId()==R.id.nav_slideshow){
                FragmentTransaction fragmentTransaction=getSupportFragmentManager().beginTransaction();
                fragmentTransaction.replace(R.id.mainTarget,SupportFrag2.newInstance("SlideShow"));
                fragmentTransaction.commit();
            }
            else {
                Toast.makeText(MainActivity.this,"No Data Found",Toast.LENGTH_LONG).show();
            }



            return true;
        }
    });
