意图导航抽屉活动不工作

我一直在尝试将导航抽屉活动添加到我的代码中，我遵循了一个旧教程，在创建时没有创建片段，但我仍然尝试使其工作，我认为我做的一切都是正确的，但当打开模拟器时，应用程序并没有将我带到活动，而是带到启动程序（？），是模拟器还是代码？

导航抽屉：

public class NavigationDrawerActivity extends AppCompatActivity {

    private AppBarConfiguration mAppBarConfiguration;

    FirebaseDatabase database;
    DatabaseReference category;
    TextView txtFullName;
    RecyclerView recyclerView;
    RecyclerView.LayoutManager layoutManager;


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

        Toolbar toolbar = findViewById(R.id.toolbar);
        toolbar.setTitle("Options");
        setSupportActionBar(toolbar);

        //Init. Firebase
        database = FirebaseDatabase.getInstance();
        category = database.getReference("Category");

        FloatingActionButton fab = findViewById(R.id.fab);
        fab.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
                        .setAction("Action", null).show();
            }
        });
        DrawerLayout drawer = findViewById(R.id.drawer_layout);
        NavigationView navigationView = findViewById(R.id.nav_view);
        // Passing each menu ID as a set of Ids because each
        // menu should be considered as top level destinations.
        mAppBarConfiguration = new AppBarConfiguration.Builder(
                R.id.nav_home, R.id.nav_gallery, R.id.nav_slideshow)
                .setDrawerLayout(drawer)
                .build();
        NavController navController = Navigation.findNavController(this, R.id.nav_host_fragment);
        NavigationUI.setupActionBarWithNavController(this, navController, mAppBarConfiguration);
        NavigationUI.setupWithNavController(navigationView, navController);

        //Set name for User
        View HeaderView = navigationView.getHeaderView(0);
        txtFullName = findViewById(R.id.txtFullName);
        if (Common.currentUser != null) {
            txtFullName.setText(Common.currentUser.getName());
            finish();
        } else if (Common.CurrentFirebaseUser != null) {
            txtFullName.setText(Common.CurrentFirebaseUser.getDisplayName());
            finish();
        }

        //Load Options
        recyclerView = findViewById(R.id.recycler);
        recyclerView.setHasFixedSize(true);
        layoutManager = new LinearLayoutManager(this);
        recyclerView.setLayoutManager(layoutManager);

        loadFilter();
    }

    private void loadFilter() {

        FirebaseRecyclerAdapter<Category,FilterViewHolder> adapter = new FirebaseRecyclerAdapter<Category, FilterViewHolder>(Category.class, R.layout.filter_item, FilterViewHolder.class, category) {
            @Override
            protected void populateViewHolder(FilterViewHolder filterViewHolder, Category category, int i) {
                FilterViewHolder.txtFilterName.setText(category.getName());
                Picasso.with(getBaseContext()).load(category.getImage())
                        .into(filterViewHolder.imageView);
                Category clickItem = category;
                filterViewHolder.setItemClickListener(new ItemClickListener() {
                    @Override
                    public void onClick(View view, int position, boolean isLongClick) {
                        Toast.makeText(NavigationDrawerActivity.this, ""+ clickItem.getName(), Toast.LENGTH_SHORT).show();
                    }
                });
            }
        };
        recyclerView.setAdapter(adapter);

    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.navigation_drawer, menu);
        return true;
    }

    @Override
    public boolean onSupportNavigateUp() {
        NavController navController = Navigation.findNavController(this, R.id.nav_host_fragment);
        return NavigationUI.navigateUp(navController, mAppBarConfiguration)
                || super.onSupportNavigateUp();
    }
}

登录到导航抽屉（忽略登录逻辑）：

public class SignIn extends AppCompatActivity {

    private static final int RC_SIGN_IN = 1;
    Button btnSignIn;
    ImageView btnGoogle;
    EditText edtTxtPhone, edtTxtPassword;

        FirebaseUser user = mAuth.getCurrentUser();
        if (user != null) {

            startActivity(intent);
        }
    }

我试图查看创建的碎片是否是问题所在，NavigationDrawerActivity是否应该使用其他xml文件，或者我是否缺少一些逻辑，但我仍然不明白为什么它会将我带到Launcher Activity而不是NavigationDrawer Activity，SignIn逻辑与NavigationDrawor Activity以外的其他活动一起工作
