NavigationDrawer活动导致空白屏幕

Question

我一直在努力找出代码中出了什么问题。我有一个Firebase应用程序，该应用程序在通过身份验证后会进入导航抽屉，但会加载到空白屏幕。仅测试setupUI（）函数，导航抽屉即可工作，但是在嵌套函数中没有任何错误，因此我对正在发生的事情感到非常困惑。我的onActivityResult是给我带来问题的原因。谁能帮我吗？感谢您的指导。如果您需要代码的其他任何部分，请告诉我。

我的主要活动代码如下：

public class MainActivity extends AppCompatActivity {

DatabaseReference user_information;
private static final int MY_REQUEST_CODE = 7117;
List<AuthUI.IdpConfig> providers;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    Paper.init(this);

    // Init firebase
    user_information = FirebaseDatabase.getInstance().getReference(Common.USER_INFORMATION);

    // init providers
    providers = Arrays.asList(
            new AuthUI.IdpConfig.EmailBuilder().build(),
            new AuthUI.IdpConfig.GoogleBuilder().build()
    );

    // Request Permission Locatoin
    Dexter.withActivity(this)
            .withPermission(Manifest.permission.ACCESS_FINE_LOCATION)
            .withListener(new PermissionListener() {
                @Override
                public void onPermissionGranted(PermissionGrantedResponse response) {
                    showSignInOptions();
                }

                @Override
                public void onPermissionDenied(PermissionDeniedResponse response) {
                    Toast.makeText(MainActivity.this, "you gotta accept the terms", Toast.LENGTH_SHORT).show();
                }

                @Override
                public void onPermissionRationaleShouldBeShown(PermissionRequest permission, PermissionToken token) {

                }
            }).check();





}

private void showSignInOptions() {
    startActivityForResult(AuthUI.getInstance().createSignInIntentBuilder().setAvailableProviders(providers).build(),MY_REQUEST_CODE);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    setupUI();
    if(requestCode == MY_REQUEST_CODE){
        IdpResponse response = IdpResponse.fromResultIntent(data);
        if(resultCode == RESULT_OK)
        {
            final FirebaseUser firebaseUser = FirebaseAuth.getInstance().getCurrentUser();
            //Check if user exists on DB
            user_information.orderByKey()
                    .equalTo(firebaseUser.getUid())
                    .addListenerForSingleValueEvent(new ValueEventListener() {
                        @Override
                        public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
                            if(dataSnapshot.getValue() == null){
                                if(!dataSnapshot.child(firebaseUser.getUid()).exists()){
                                    Common.loggedUser = new User(firebaseUser.getUid(),firebaseUser.getEmail());
                                    // Add to database
                                    user_information.child(Common.loggedUser.getUid())
                                            .setValue(Common.loggedUser);
                                }
                            }
                            else {
                                Common.loggedUser = dataSnapshot.child(firebaseUser.getUid()).getValue(User.class);

                            }
                            Paper.book().write(Common.USER_UID_SAVE_KEYS,Common.loggedUser.getUid());
                            updateToken(firebaseUser);
                            setupUI();
                        }

                        @Override
                        public void onCancelled(@NonNull DatabaseError databaseError) {

                        }
                    });
        }

    }
}

private void setupUI() {
    startActivity(new Intent(MainActivity.this,HomeActivity.class));
    finish();
}

private void updateToken(final FirebaseUser firebaseUser) {
    final DatabaseReference tokens = FirebaseDatabase.getInstance()
            .getReference(Common.TOKENS);

    FirebaseInstanceId.getInstance().getInstanceId()
            .addOnSuccessListener(new OnSuccessListener<InstanceIdResult>() {
                @Override
                public void onSuccess(InstanceIdResult instanceIdResult) {
                    tokens.child(firebaseUser.getUid())
                            .setValue(instanceIdResult.getToken());
                }
            }).addOnFailureListener(new OnFailureListener() {
        @Override
        public void onFailure(@NonNull Exception e) {
            Toast.makeText(MainActivity.this, ""+e.getMessage(), Toast.LENGTH_SHORT).show();
        }
    });
}
}

我的普通班级文件是：

public class Common {

public static final String USER_INFORMATION = "UserInformation";
public static final String USER_UID_SAVE_KEYS = "SaveUid" ;
public static final String TOKENS = "Tokens";
public static User loggedUser;
}
