从基于UID的Firebase存储获取照片

Question

我正面临一个问题。 我通过UID拍照， 但问题是在firebase数据库中，图像正在替换 如果我使用推送，那么应用程序没有从firebase获取图像

Firebase Database Image

如果我从数据库中移除推送，则会显示图像，但正如您所看到的那样，每次用户上传图像时图像都会重叠

这是我的onActivityResult

代码

 @Override
        protected void onActivityResult ( int requestCode, int resultCode, Intent data) {
            super.onActivityResult(requestCode, resultCode, data);
            final FirebaseUser currentFirebaseUser = FirebaseAuth.getInstance().getCurrentUser();

            if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK) {
                TitleName=title.getText().toString();
                progressDialog.setMessage("Uploading .....");
                progressDialog.show();
                Uri uri = data.getData();
                StorageReference filePath = storageReference.child("Photos").child(currentFirebaseUser.getUid()).child(uri.getLastPathSegment());

                filePath.putFile(uri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
                    @Override
                    public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                        Uri downloadPath = taskSnapshot.getDownloadUrl();
                        Glide.with(MainActivity.this).load(downloadPath).centerCrop().into(imageView);

                        Toast.makeText(getApplicationContext(), "DONE" + TitleName, Toast.LENGTH_SHORT).show();
                        progressDialog.dismiss();
                        //creating the upload object to store uploaded image details
                        Upload upload = new Upload(taskSnapshot.getDownloadUrl().toString(), TitleName);

                        //adding an upload to firebase database
                     //   String uploadId = mDatabase.push().getKey();
                        mDatabase.child(currentFirebaseUser.getUid())***.push().***setValue(upload);
                    }
                }).addOnFailureListener(new OnFailureListener() {
                    @Override
                    public void onFailure(@NonNull Exception e) {
                        progressDialog.dismiss();
                        Toast.makeText(getApplicationContext(), e.getMessage(), Toast.LENGTH_LONG).show();

                    }
                });

            }



        }

如果我从

删除推送

mDatabase.child(currentFirebaseUser.getUid())***.push().***setValue(upload);

然后图像将显示在recyclerView上。

有什么建议吗？

ShowImagesActivity

public class ShowImagesActivity extends AppCompatActivity {
    //recyclerview object
    private RecyclerView recyclerView;

    //adapter object
    private RecyclerView.Adapter adapter;

    //database reference
    private DatabaseReference mDatabase;

    //progress dialog
    private ProgressDialog progressDialog;

    //list to hold all the uploaded images
    private List<Upload> uploads;

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


        recyclerView = (RecyclerView) findViewById(R.id.recyclerView);
        recyclerView.setHasFixedSize(true);
        recyclerView.setLayoutManager(new LinearLayoutManager(this));


        progressDialog = new ProgressDialog(this);

        uploads = new ArrayList<>();

        //displaying progress dialog while fetching images
        progressDialog.setMessage("Loading your memories ...");
        progressDialog.show();
        mDatabase = FirebaseDatabase.getInstance().getReference(Constants.DATABASE_PATH_UPLOADS);

        //adding an event listener to fetch values
        mDatabase.addValueEventListener(new ValueEventListener() {
            @Override
            public void onDataChange(DataSnapshot snapshot) {
                //dismissing the progress dialog
                progressDialog.dismiss();

                //iterating through all the values in database
                for (DataSnapshot postSnapshot : snapshot.getChildren()) {
                    Upload upload = postSnapshot.getValue(Upload.class);
                    uploads.add(upload);
                }
                //creating adapter
                adapter = new MyAdapter(getApplicationContext(), uploads);

                //adding adapter to recyclerview
                recyclerView.setAdapter(adapter);
            }

            @Override
