Question

我正在将图片上传到我的应用程序中的Firebase存储中。可以上传，并且可以在Firebase存储中在线查看。当我尝试获取它并在图像视图中显示它时，它没有出现在图像视图中，而是消失了。我已经尝试过Piccaso和滑行，但没有任何效果。代码附在下面

上传代码：

 @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == PICK_IMAGE && resultCode == RESULT_OK && data != null && data.getData() != null) {

            uri = data.getData();

            try {
                Bitmap bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), uri);




                profile_image = findViewById(R.id.profileimage);
                profile_image.setImageBitmap(bitmap);



                imageRef=storageReference.child(userID);
                imageRef.putFile(uri)
                        .addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
                            @Override
                            public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                                //if the upload is successful
                                //hiding the progress dialog
                                //and displaying a success toast
                                //dismissDialog();

                                profilePicUrl = taskSnapshot.getMetadata().getReference().getDownloadUrl().toString();
                            }
                        })
                        .addOnFailureListener(new OnFailureListener() {
                            @Override
                            public void onFailure(@NonNull Exception exception) {
                                //if the upload is not successful
                                //hiding the progress dialog
                                // dismissDialog();
                                //and displaying error message
                                Toast.makeText(profile.this, exception.getCause().getLocalizedMessage(), Toast.LENGTH_LONG).show();
                            }


                        });















            } catch (IOException e) {
                e.printStackTrace();
            }
        }

下载并加载到图像视图代码中：


        fbstorage=FirebaseStorage.getInstance();
        storageReference=fbstorage.getReference();
        imageRef=storageReference.child(userID);
        final String h=imageRef.getDownloadUrl().toString();

        storageReference.child(userID).getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
            @Override
            public void onSuccess(Uri uri) {

                Toast.makeText(profile.this, "hello", Toast.LENGTH_SHORT).show();
                Picasso.with(profile.this).load(h).into(profile_image);

            }
        });
