Question

我有一个使用 Firebase 的应用。当用户登录时，活动将检查 Firestore数据库中是否存在用户数据，如果存在则将其转到应用中。

这是它的代码（这是OnCreate）

FirebaseFirestore
        .getInstance()
        .document("users/" + uID)
        .get()
        .addOnCompleteListener(new OnCompleteListener<DocumentSnapshot>() {
            @Override
            public void onComplete(@NonNull Task<DocumentSnapshot> task) {
                if (task.isSuccessful()) {
                    if (task.getResult().exists()) {
                        DocumentSnapshot documentSnapshot = task.getResult();
                        name.setText(documentSnapshot.getString("name"));
                        progressBar.setVisibility(View.VISIBLE);
                        Glide
                            .with(SetUserData.this)
                            .load(FirebaseStorage.getInstance().getReference("profile_images/" + uID))
                            .skipMemoryCache(true)
                            .diskCacheStrategy(DiskCacheStrategy.NONE)
                            .error(R.drawable.default_user_icon)
                            .listener(new RequestListener<Drawable>() {
                                @Override
                                public boolean onLoadFailed(@Nullable GlideException e, Object model, Target<Drawable> target, boolean isFirstResource) {
                                    if (e.getRootCauses().size() == 1 && e.getRootCauses().get(0) instanceof StorageException) {
                                        if (((StorageException) e.getRootCauses().get(0)).getErrorCode() == StorageException.ERROR_OBJECT_NOT_FOUND) {
                                            Toast.makeText(SetUserData.this, "testing", Toast.LENGTH_LONG).show();
                                            progressBar.setVisibility(View.GONE);
                                            progressHUD.dismiss();
                                        }
                                    } else {
                                        Toast.makeText(SetUserData.this, "Some error occurred", Toast.LENGTH_LONG).show();
                                        Log.e("Glide Exception", e.getMessage());
                                        finish();
                                    }
                                    return false;
                                }

                                @Override
                                public boolean onResourceReady(Drawable resource, Object model, Target<Drawable> target, DataSource dataSource, boolean isFirstResource) {
                                    progressBar.setVisibility(View.GONE);
                                    progressHUD.dismiss();
                                    return false;
                                }
                        }).into(imageView);
                    }
                    else {
                        progressBar.setVisibility(View.GONE);
                        progressHUD.dismiss();
                    }
                } else {
                    Toast.makeText(SetUserData.this, "Some error occurred", Toast.LENGTH_LONG).show();
                    Log.e("Firestore error", task.getException().getMessage());
                    finish();
                }
            }
        }
    );

我有一个活动，当我按下ImageView时，会按下image cropping tool is invoked。这是setOnClickListener()侦听器的代码：

imageView.setOnClickListener(
    new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            CropImage
                    .activity()
                    .setGuidelines(CropImageView.Guidelines.ON)
                    .start(SetUserData.this); //get image and crop - custom library
        }
    }
);

这是onActivityResult()方法：

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == CropImage.CROP_IMAGE_ACTIVITY_REQUEST_CODE) {
        CropImage.ActivityResult result = CropImage.getActivityResult(data);
        if (resultCode == RESULT_OK) {
            imageUri = result.getUri();
            try {
                imageView.setImageBitmap(MediaStore.Images.Media.getBitmap(getContentResolver(), imageUri));
            } catch (IOException e) {
                e.printStackTrace();
            }
        } else if (resultCode == CropImage.CROP_IMAGE_ACTIVITY_RESULT_ERROR_CODE) {
            result.getError().printStackTrace();
            Toast.makeText(this, "Some error has occurred, please try again", Toast.LENGTH_LONG).show();
        }
    }
}

每次我尝试使用 Glide ImageView的{{1}}，onLoadFailed方法设置图像时，我都不知道如何或为什么，我所知道的不应该。我知道由于我在该方法中放入了listener()而使它得以执行。 Glide 语句和以下 Firestore 语句上方的代码不会不执行，仅Glide toast()方法。 Video link

我已经花了2天了，这让我发疯了，不知道为什么会这样吗？

滑行监听器在不应该被调用时被调用
