嗨，每个人都在做一个应用程序，使用firebaseDatabase为用户信息和firebaseStorage保存图像，我想把图像的路径上传到firebaseStorage在firebaseDatabase下的用户信息，这样我可以显示像配置文件图片的图像，所以我使用这个上传图像和mainActivity显示图像。我确实在寻找解决办法，也得到了一些，但是没有效果，或者我不知道如何让它起作用。我是安卓新手

上载图像

 public String getExtension(Uri uri) {
    ContentResolver contentResolver = getContentResolver();
    MimeTypeMap mimeTypeMap = MimeTypeMap.getSingleton();
    return mimeTypeMap.getMimeTypeFromExtension(contentResolver.getType(uri));
}

private void uploadImage() {
 StorageReference reference = mStorage.child(System.currentTimeMillis()+"."+getExtension(imageUri));


    uploadTask= reference.putFile(imageUri)
            .addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
                @Override
                public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {


                    // Get a URL to the uploaded content
                   // Uri downloadUrl = taskSnapshot.getDownloadUrl();

                    Toast.makeText(AddImageActivity.this,"Image Uploaded",Toast.LENGTH_SHORT).show();

                    Intent ii = new Intent(AddImageActivity.this,MainActivity.class);
                    startActivity(ii);
                    finish();

                }
            })
            .addOnFailureListener(new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception exception) {
                    // Handle unsuccessful uploads
                    // ...
                }
            });

}

维护性

 public class MainActivity extends AppCompatActivity {
 ImageView profilePic ;
 TextView nameProfile ;
  DatabaseReference databaseReference ;
 FirebaseUser fUser;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    profilePic=findViewById(R.id.imageProfile);
    nameProfile = findViewById(R.id.nameProfile);

   fUser=FirebaseAuth.getInstance().getCurrentUser();
   databaseReference = FirebaseDatabase.getInstance().getReference("Users").child(fUser.getUid());

    databaseReference.addValueEventListener(new ValueEventListener() {
        @Override
        public void onDataChange(@NonNull DataSnapshot snapshot) {
            User user = snapshot.getValue(User.class);
            nameProfile.setText(user.getName());
            Glide.with(getApplicationContext()).load(user.getImageURL()).into(profilePic);

        }

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

        }
    });


}

}
