Question

因此，我想让用户同时将多个图像上传到Firebase存储。我已经成功完成了该部分，但是现在我想找回图像。最初，我为每个用户上传一张图像，并将图像ID保存到实时数据库中，因此通过图像ID取回图像非常容易。但是现在如何为每个用户将一个以上的图像保存到实时数据库中，我不能使用相同的子名称，因为它将被旧的子名称替换。有什么想法吗？

重叠图像并在实时数据库上设置ID：

private void Fileuploader() throws FileNotFoundException {
        String imageid;

        progress.showProgress(profuctadd.this,"Loading...",false);
        DatabaseHelper databaseHelper = new DatabaseHelper(profuctadd.this);
        Cursor getimage = databaseHelper.GetPath();
        int count = 0;
        while (getimage.moveToNext()){
            Bitmap bm = BitmapFactory.decodeFile(getimage.getString(0));
            ByteArrayOutputStream out = new ByteArrayOutputStream();
            bm.compress(Bitmap.CompressFormat.JPEG, 35, out);
            imageid = arabic.getText().toString()+"-"+System.currentTimeMillis()+"_"+(count++)+"."+getExtension(uri);
            System.out.println("IMAGES UPLOADEDDDD: "+ imageid);
            String id = getIntent().getStringExtra("storeid");
            member.setImageid(imageid);
            reference.child(id).child(arname).setValue(member);
            byte[] data = out.toByteArray();
            StorageReference Ref = mStorageRef.child(imageid);
            Ref.putBytes(data)
                    .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(profuctadd.this,"Image uploaded",Toast.LENGTH_LONG).show();
                            progress.hideProgress();
                            Intent intent = new Intent(profuctadd.this,showProducts.class);
                            intent.putExtra("spec",getIntent().getStringExtra("spec"));
                            intent.putExtra("storeid",getIntent().getStringExtra("storeid"));
                            startActivity(intent);
                            DatabaseHelper mDatabaseHelper = new DatabaseHelper(profuctadd.this);
                            Cursor cursor2 = mDatabaseHelper.DeleteDataOfTableImagesAr();
                            cursor2.moveToNext();
                        }
                    })
                    .addOnFailureListener(new OnFailureListener() {
                        @Override
                        public void onFailure(@NonNull Exception exception) {
                            // Handle unsuccessful uploads
                            // ...
                            Toast.makeText(profuctadd.this,"Failed",Toast.LENGTH_LONG).show();
                        }
                    });

        }





    }

我的Firebase数据库：

Answer 1

您可以在图像节点中保存多个特定用户的图像。

DatabaseReference dr =  FirebaseDatabase.getInstance().getReference("tL131);

 dr.child("images").push().setValue(String.ValueOf(taskSnapshot.getDownloadUrl()));

从Firebase存储和实时数据库获取图像
