Firebase存储：如何将多个文件上载到同一文件路径

Question

我开发了一个应用程序，用户可以拍摄两张照片，然后将它们并排显示在Linearlayout（水平方向）中。一旦显示图片。我有一个用户按下上传按钮，将图片上传到firebase。我遇到的问题是只有一张图片正在上传而另一张则没有。如何将两张图片上传到同一文件路径，但为它们指定不同的名称：这是我当前可怕尝试的代码。

  _uploadBtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                image_one.setDrawingCacheEnabled(true);
                image_one.buildDrawingCache();
                Bitmap bitmapOne = image_one.getDrawingCache();
                ByteArrayOutputStream imageoneBytes = new ByteArrayOutputStream();
                bitmapOne.compress(Bitmap.CompressFormat.JPEG, 100, imageoneBytes);
                byte[] dataOne = imageoneBytes.toByteArray();

                StorageReference filepathOne = mStorage.child(user_data.getString("uidkey", null)).child("Photos").child(_imageoneText.getText().toString());
                filepathOne.putBytes(dataOne).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
                    @Override
                    public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                        Toast.makeText(getBaseContext(), "Upload One Done", Toast.LENGTH_LONG).show();
                        Uri downloadUrl = taskSnapshot.getDownloadUrl();
                        Picasso.with(IdentificationActivity.this).load(downloadUrl).fit().centerCrop().into(image_one);

                    }
                }).addOnFailureListener(new OnFailureListener() {
                    @Override
                    public void onFailure(@NonNull Exception e) {

                        Toast.makeText(getBaseContext(), "Upload one failed", Toast.LENGTH_LONG).show();
                    }
                });

                image_two.setDrawingCacheEnabled(true);
                image_two.buildDrawingCache();
                Bitmap bitmapTwo = image_two.getDrawingCache();
                ByteArrayOutputStream imagetwoBytes = new ByteArrayOutputStream();
                bitmapTwo.compress(Bitmap.CompressFormat.JPEG, 100, imageoneBytes);
                byte[] dataTwo = imagetwoBytes.toByteArray();

                StorageReference filepathTwo = mStorage.child(user_data.getString("uidkey", null)).child("Photos").child(_imagetwotext.getText().toString());
                filepathTwo.putBytes(dataTwo).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
                    @Override
                    public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                        Toast.makeText(getBaseContext(), "Upload two Done", Toast.LENGTH_LONG).show();
                        Uri downloadUrl = taskSnapshot.getDownloadUrl();
                        Picasso.with(IdentificationActivity.this).load(downloadUrl).fit().centerCrop().into(image_two);

                    }
                }).addOnFailureListener(new OnFailureListener() {
                    @Override
                    public void onFailure(@NonNull Exception e) {

                        Toast.makeText(getBaseContext(), "Upload two failed", Toast.LENGTH_LONG).show();
                    }
                });

            }
        });
