Question

我目前正在使用Firebase处理聊天应用。对于Firebase身份验证，我使用getImageUrl()从Firebase用户获取图片Uri，但毕加索图书馆没有加载任何图像以显示也没有出现任何错误，但是当我使用直接链接时，它完美无缺。

public class MainActivity extends AppCompatActivity {

    private FirebaseAuth mAuth;
    private FirebaseAuth.AuthStateListener mAuthListener;
    private FirebaseUser User;
    private ImageView profileImg;

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


        mAuth = FirebaseAuth.getInstance();
        User = mAuth.getCurrentUser();

        profileImg= (ImageView) findViewById(R.id.profileImage);
        mAuthListener = new FirebaseAuth.AuthStateListener() {
            @Override
            public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
                FirebaseUser user = firebaseAuth.getCurrentUser();
                if (user != null) {
                    // User is signed in
                    TextView name = (TextView) findViewById(R.id.profilenameTv);
                    name.setText(user.getDisplayName());
                    profileImg = (ImageView) findViewById(R.id.profileImage);
                    Picasso.with(getApplicationContext()).load(user.getPhotoUrl()).fit().centerCrop().into(profileImg);
                }else{
                    // User is signed out
                    startActivity(new Intent(getApplicationContext(),Signup.class));
                }
            }
        };


    }

这是我的EditProfile类：

public class editProfile extends AppCompatActivity {

    private FirebaseAuth mAuth;
    private FirebaseAuth.AuthStateListener mAuthListener;
    private FirebaseDatabase mDatabase;
    private DatabaseReference mRef;
    private StorageReference mStorage;
    private FirebaseUser User;

    private Button submitBtn, changePassBtn, deleteBtn;
    private ImageButton addProImage;
    private EditText UsernameEt, currentPassEt, newPassEt ;

    int REQUEST_CODE = 1;

    private Uri PhotoDownloadUri ;
    private Uri photoUri;

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

        //firebase initilation
        mAuth = FirebaseAuth.getInstance();
        mStorage = FirebaseStorage.getInstance().getReference();
        mDatabase = FirebaseDatabase.getInstance();
        mRef = mDatabase.getReference();
        User = mAuth.getCurrentUser();

        //View initialization
        //EditText
        UsernameEt= (EditText) findViewById(R.id.usernameEt);
        currentPassEt = (EditText) findViewById(R.id.curentPass);
        newPassEt = (EditText) findViewById(R.id.newPass);
        //Button
        submitBtn = (Button) findViewById(R.id.sumitBtn);
        changePassBtn = (Button) findViewById(R.id.ChangePassBtn);
        deleteBtn = (Button) findViewById(R.id.deleteBtn);
        //imageButton
        addProImage = (ImageButton) findViewById(R.id.addProImg);
        //add photo on start
        Picasso.with(getApplicationContext()).load(User.getPhotoUrl()).fit().centerCrop().into(addProImage);
        // request permission
        requestPermission();

        // open gallery
        openGallery();

        // delete mStorage data
        deleteBtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                if(User.getPhotoUrl() == PhotoDownloadUri){
                    mStorage.child("UserPhoto").child(photoUri.getLastPathSegment()).delete().addOnCompleteListener(new OnCompleteListener<Void>() {
                        @Override
                        public void onComplete(@NonNull Task<Void> task) {
                            if(task.isSuccessful()){
                                //photo replaced with default photo
                                addProImage.setImageDrawable(getDrawable(R.mipmap.ic_launcher));
                                Toast.makeText(getApplicationContext(), " Photo deleted Successfully ", Toast.LENGTH_SHORT).show();
                            }
                        }
                    });

        // Add update user profile info
        submitBtn.setOnClickListener(new View.OnClickListener() {

                String Name =UsernameEt.getText().toString().trim();
                String Photouri = PhotoDownloadUri.toString();
                // Calling method

Answer 1

尝试

// Camera.js

import { Euler } from 'three'

const euler = new Euler( 0, 0, 0, 'YXZ' )

export const updateCamera = (camera, motion) => {
  euler.x = motion.rotation.x
  euler.y = motion.rotation.y
  camera.quaternion.setFromEuler( euler )
  camera.position.copy( motion.position )
  camera.position.y += 10.0
}

Picasso Library图片加载无法使用Firebase auth.getCurentUser.getPhotoUrl
