Kotlin - Firebase and Glide - получите URL изображения, чтобы он мог использовать Glide

2 голосов

Мне трудно получить URL-адрес изображения из хранилища Firebase, я получил URL-адрес фотографии из базы данных, но, как я знаю, Glide не может получить изображение по этой ссылке: com.google.firebase .storage. UploadTask@62873ce

Вот мои ссылки на хранилища и базы данных: 

 private fun StorageReference.uploadUserPhoto(uid: String, photo: Uri,
                                             onSuccess: (UploadTask.TaskSnapshot) -> Unit) {
    child("users/$uid/photo").putFile(mImageUri).addOnCompleteListener {
        if (it.isSuccessful) {
            mStorage.child("users/$uid/photo").downloadUrl.addOnCompleteListener { task ->
                if (it.isSuccessful) {
                    onSuccess(it.result!!)
                } else {
                    showToast(it.exception!!.message!!)
                }
            }
        }
    }
}


private fun DatabaseReference.updateUserPhoto(uid: String, photoUrl: String,
                                              onSuccess: () -> Unit){
    child("users/$uid/photo").setValue(photoUrl)
        .addOnCompleteListener {
            if (it.isSuccessful) {
                onSuccess()
            } else {
                showToast(it.exception!!.message!!)
            }
        }
}

вот функция: 

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    if (requestCode == TAKE_PICTURE_REQUEST_CODE && resultCode == RESULT_OK) {
        val uid = mAuth.currentUser!!.uid
        mStorage.uploadUserPhoto(uid, mImageUri) {
            val photoUrl = it.task.toString()
            mDatabase.updateUserPhoto(uid, photoUrl) {
                mUser = mUser.copy(photo = photoUrl)
                profile_image.loadUserPhoto(mUser.photo)
            }
        }
    }
}

Я попытался изменить 

val photoUrl = it.task.toString()

до 

val photoUrl = it.downloadUrl.toString()

, но в качестве неразрешенной ссылки выделяется «downloadUrl»

Полный код:

Измените свой метод uploadUserPhoto следующим образом 

    private fun StorageReference.uploadUserPhoto(uid: String, photo: Uri,
                                             onSuccess: (String) -> Unit) {
    val uTask = mStorage.child("users/$uid/photo").putFile(mImageUri)
    child("users/$uid/photo").putFile(mImageUri).addOnCompleteListener {
        if (it.isSuccessful) {
            uTask.continueWithTask { task ->
                mStorage.child("users/$uid/photo").downloadUrl
            }.addOnCompleteListener{
               if (it.isSuccessful && it.result != null) {
                    onSuccess(it.result!!.toString)
                } else {
                    showToast(it.exception!!.message!!)
                }
            }
        }
    }
}

В вашем onActivityResult используйте URL-адрес как 

 val photoUrl = it
...
