When I just added it, everything is fine, but when I restart the application, only textViews is displayed. There is an empty space instead of an imageView.
My recycler adapter:
class PersonAdapter(options: FirebaseRecyclerOptions<Outfit?>) :
FirebaseRecyclerAdapter<Outfit, personsViewHolder>(options) {
override fun onBindViewHolder(holder: personsViewHolder, position: Int, model: Outfit) {
holder.name.text = model.name
holder.brand.text = model.brand
holder.size.text = model.size
holder.comment.text = model.comment
holder.price.text = model.price
Picasso.get().load(model.imageUrl).into(holder.imageView) //Glide analog
}
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): personsViewHolder {
val view = LayoutInflater.from(parent.context)
.inflate(R.layout.recycler_item, parent, false)
return personsViewHolder(view)
}
class personsViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
var name: TextView = itemView.findViewById(R.id.tv_name_value)
var brand: TextView = itemView.findViewById(R.id.tv_brand_value)
var size: TextView = itemView.findViewById(R.id.tv_size_value)
var comment: TextView = itemView.findViewById(R.id.tv_comment_value)
var price: TextView = itemView.findViewById(R.id.tv_price_value)
var imageView: ImageView = itemView.findViewById(R.id.imageView)
}
}
Class what add to database:
private var dataBase: DatabaseReference? = null
private lateinit var outfitImage: ImageView
private var imageUri: Uri? = null
private var id: Int = 0
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_add_outfit)
nameView = findViewById(R.id.et_outfitName)
brandView = findViewById(R.id.et_outfitBrand)
sizeView = findViewById(R.id.et_outfitSize)
commentView = findViewById(R.id.et_outfitComment)
priceView = findViewById(R.id.et_outfitPrice)
btnAdd = findViewById(R.id.btn_addOutfit)
btnLoad = findViewById(R.id.btn_load)
btnAdd?.setOnClickListener {
onClickSave()
Toast.makeText(this, "Added to database", Toast.LENGTH_SHORT).show()
startActivity(Intent(this, MainActivity::class.java))
}
btnLoad?.setOnClickListener {
onClickRead()
}
outfitImage = findViewById(R.id.iv_upload_image)
outfitImage.setOnClickListener {
chooseImage()
}
}
//SAVE BUTTON
private fun onClickSave() {
dataBase = FirebaseDatabase.getInstance().getReference(UUID.randomUUID().toString())
dataBase?.setValue(
Outfit(
nameView?.text.toString(),
brandView?.text.toString(),
sizeView?.text.toString(),
commentView?.text.toString(),
priceView?.text.toString(),
imageUri.toString()
)
)
uploadImageToFirebase(imageUri!!)
}
//----------------UPLOAD IMAGE-----------------------
private fun chooseImage() {
val intent = Intent()
intent.type = "image/*"
intent.action = Intent.ACTION_GET_CONTENT
startActivityForResult(
Intent.createChooser(intent, "Please select..."), 1
)
}
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
if (requestCode == 1 && resultCode == Activity.RESULT_OK && data != null && data.data != null) {
// Get the Uri of data
imageUri = data.data
outfitImage.setImageURI(imageUri)
}
}
private fun uploadImageToFirebase(imageUri: Uri) {
val pd: ProgressDialog = ProgressDialog(this)
pd.setTitle("Uploading image...")
pd.show()
val fileName = UUID.randomUUID().toString()
val refStorage = FirebaseStorage.getInstance().reference.child("images/$fileName")
refStorage.putFile(imageUri)
.addOnSuccessListener { taskSnapshot ->
taskSnapshot.storage.downloadUrl.addOnSuccessListener {
pd.dismiss()
Snackbar.make(
findViewById(android.R.id.content),
"Image uploaded.",
Snackbar.LENGTH_LONG
)
val imageUrl = it.toString()
}
}
.addOnFailureListener { e ->
print(e.message)
pd.dismiss()
}
//progressbar
.addOnProgressListener {
var progressPercents: Double = (100.00 * it.bytesTransferred / it.totalByteCount)
pd.setMessage("Percentage: $progressPercents%")
}
}
}
Logic at MainActivity:
mbase = FirebaseDatabase.getInstance().reference
recyclerView = findViewById(R.id.recycler1)
recyclerView.layoutManager = LinearLayoutManager(this)
val options = FirebaseRecyclerOptions.Builder<Outfit>()
.setQuery(mbase!!, Outfit::class.java)
.build()
// Connecting object of required Adapter class to the Adapter class itself
adapter = PersonAdapter(options)
// Connecting Adapter class with the Recycler view*/
recyclerView.adapter = adapter
swipeRefreshLayout.setOnRefreshListener(this)
Here are screenshots of how everything looks in the backend: my backend
