大小为[0x0]的null加载失败，类为com.bumptech.glide.load.engine.GlideException:收到的null模型 [英] Load failed for null with size [0x0] class com.bumptech.glide.load.engine.GlideException: Received null model

问题描述

我正在尝试加载保存在Firebase上的照片，保存成功，但是无法再次加载图像，错误是

I'm trying to load a photo I saved on firebase, It's saved successful but it can't get the image loaded again the error is

大小为[0x0]的null加载失败com.bumptech.glide.load.engine.GlideException类:收到的空模型"

"Load failed for null with size [0x0] class com.bumptech.glide.load.engine.GlideException: Received null model"

我在代码上使用了简单的行

I use the simple line on my code

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
    super.onViewCreated(view, savedInstanceState)

    currentUser?.let{user ->
        Glide.with(this)
            .load(user.photoUrl)

            .into(image_view)

我在Build.Gradle上的实现

感谢您将来的回答！

顺便说一下，这是我完整的片段代码

BTW here's my entire code for the fragment

NotificationsFragment类:Fragment(){

class NotificationsFragment : Fragment() {

private lateinit var notificationsViewModel: NotificationsViewModel
private lateinit var imageUri: Uri
private val REQUEST_IMAGE_CAPTURE = 100
private val currentUser = FirebaseAuth.getInstance().currentUser
private val user = FirebaseDatabase.getInstance()



override fun onCreateView(

    inflater: LayoutInflater,
    container: ViewGroup?,
    savedInstanceState: Bundle?):
        View? {
    notificationsViewModel =
        ViewModelProviders.of(this).get(NotificationsViewModel::class.java)
    return inflater.inflate(R.layout.fragment_notifications,container,false)



}




override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
    super.onViewCreated(view, savedInstanceState)



    currentUser?.let{user ->
        Glide.with(this)
            .load(user.photoUrl)
            .placeholder(R.drawable.ic_profilepicture_box_orange_24dp)
            .into(image_view)






    }




    image_view.setOnClickListener {
        takePictureIntent()

    }
    button_save.setOnClickListener{

    }


}

private fun takePictureIntent() {
    Intent(MediaStore.ACTION_IMAGE_CAPTURE).also { pictureIntent ->
        pictureIntent.resolveActivity(activity?.packageManager!!)?.also {
            startActivityForResult(pictureIntent, REQUEST_IMAGE_CAPTURE)
        }

    }


}


override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    super.onActivityResult(requestCode, resultCode, data)

    if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == AppCompatActivity.RESULT_OK) {
        val imageBitmap = data?.extras?.get("data") as Bitmap

        uploadImageAndSaveUri(imageBitmap)
    }
}

private fun uploadImageAndSaveUri(bitmap: Bitmap) {

    val baos = ByteArrayOutputStream()
    val baos1 = ByteArrayOutputStream()
    val storageRef = FirebaseStorage.getInstance()


        .reference

        .child("pics/${FirebaseAuth.getInstance().currentUser!!.uid}")
        .child("uid" + ".JPEG")
        .child("uid" + ".PNG")
    bitmap.compress(Bitmap.CompressFormat.PNG, 100, baos1)
    bitmap.compress(Bitmap.CompressFormat.JPEG, 100, baos)
    val image = baos.toByteArray()
    val image1 = baos1.toByteArray()

    val upload = storageRef.putBytes(image)
    val upload1 = storageRef.putBytes(image1)

    upload.addOnCompleteListener { uploadTask ->
        if (uploadTask.isSuccessful){
            storageRef.downloadUrl.addOnCompleteListener{urlTask ->
                urlTask.result?.let{
                    imageUri = it
                    Toast.LENGTH_SHORT

                }

            }

        }

    }

    upload1.addOnCompleteListener { uploadTask1 ->
        if (uploadTask1.isSuccessful){
            storageRef.downloadUrl.addOnCompleteListener{urlTask ->
                urlTask.result?.let{
                    imageUri = it




                }

            }
        }

    }






    progressbar_pic.visibility = View.VISIBLE
    upload.addOnCompleteListener { uploadTask ->
        progressbar_pic.visibility = View.INVISIBLE

        if (uploadTask.isSuccessful) {
            storageRef.downloadUrl.addOnCompleteListener { urlTask ->
                urlTask.result?.let {
                    imageUri = it
                    imageUri.toString()
                    image_view.setImageBitmap(bitmap)


                }
            }
        } else {
            uploadTask.exception?.let {
                Toast.makeText(activity, "Upload Failed", Toast.LENGTH_SHORT).show();

            }
        }

    }

}

}

我已修复它，我还必须添加一些代码并进行一些编辑，这是修复程序，因此可以保存URL和照片.

I fixed it, I had to add a few more codes and edit some too, this was the fix so it would save the URL and the photo.

private  fun uploadImagetoFirebaseStorage(){
    if (selectedPhotoUri == null) return
    val filename = UUID.randomUUID().toString()
    val ref = FirebaseStorage.getInstance().getReference("/images/$filename")

    ref.putFile(selectedPhotoUri!!)
        .addOnSuccessListener {
            Log.d("dsa","$it")
            ref.downloadUrl.addOnSuccessListener {
                it.toString()

                saveUsertoFirebaseDatabase(it.toString())
            }
        }

}

private fun saveUsertoFirebaseDatabase(profileImageUrl: String){
    val uid = FirebaseAuth.getInstance().uid ?: ""
    val ref = FirebaseDatabase.getInstance().getReference("/users/$uid")
    val user = User(uid,username_edittext_register.text.toString(),profileImageUrl)

    ref.setValue(user)
        .addOnSuccessListener {
            Log.d("","Saved!!!!!!")
        }


}

}

class User(val uid:String，val username:String，val profileImageUrl:String)

class User(val uid: String, val username: String, val profileImageUrl: String)

然后我就像您通常使用的那样使用了Glide模块

then I just used Glide module as you usually use it

currentUser?.let{user ->

        Glide.with(this)

            .load(user.photoUrl)

            .into(image_view)


    }

推荐答案

确保您在firebase数据库中输入了相同的名称，例如-我正在尝试在我的应用程序中发送图像，在我的模型中我声明了一个字符串'imageUrl'，但在Firebase存储中，我给了名称'image'，请确保这两个名称相同....它将解决此问题

make sure that you have entered the same name in firebase database, e.g- I am trying to send image in my app, in my model I have declared a string 'imageUrl', but in firebase storage I gave the name 'image', make sure that the both names are same.... it will resolve the issue
