I want to make an app, where i click on button
on bottomNavigationView
and PopupWindow
opens, i can choose image (thumbnail) and Video from my gallery, add description and title. Then add provided data to recyclerView
. But i have a problem with picking image from gallery, it seems to work, i can pick image from gallery, but it doesn't change image inside popupWindow
as it suposed to.
MainActivity.kt
class MainActivity : AppCompatActivity() {
private val home = HomeFragment()
private val player = PlayerFragment()
private val profile = ProfileFragment()
private val settings = SettingsFragment()
private val getPreviewImage = registerForActivityResult(ActivityResultContracts.GetContent(), ActivityResultCallback {
val dialogView: View = layoutInflater.inflate(R.layout.popup, null)
dialogView.imageChange.setImageURI(it)
})
private val getPreviewVideo = registerForActivityResult(ActivityResultContracts.GetContent(), ActivityResultCallback {
val dialogView: View = layoutInflater.inflate(R.layout.popup, null)
dialogView.VideoSelect.setImageURI(it)
})
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
val popupButton: FloatingActionButton = findViewById(R.id.fab)
val bottomNav: BottomNavigationView = findViewById(R.id.bottomNavigationView)
bottomNav.background = null
bottomNav.menu.findItem(R.id.placeholder).isEnabled = false
replaceFragment(home)
bottomNav.setOnItemSelectedListener {
when (it.itemId) {
R.id.home -> replaceFragment(home)
R.id.player -> replaceFragment(player)
R.id.profile -> replaceFragment(profile)
R.id.settings -> replaceFragment(settings)
}
true
}
popupButton.setOnClickListener {
showDialog()
}
}
private fun replaceFragment(fragment: Fragment) {
val transaction = supportFragmentManager.beginTransaction()
transaction.replace(R.id.fragment_container, fragment)
transaction.commit()
}
private fun showDialog() {
val title = RecyclerAdapter().titles
val description = RecyclerAdapter().details
val video = RecyclerAdapter().videos
val dialog = Dialog(this)
val dialogView: View = layoutInflater.inflate(R.layout.popup, null)
val imageView = dialogView.findViewById<ImageView>(R.id.imageChange)
val videoView = dialogView.findViewById<ImageView>(R.id.VideoSelect)
val buttonImage = dialogView.findViewById<Button>(R.id.addImage)
val titleEditText = dialogView.findViewById<EditText>(R.id.titleEdit) //popUp edit field title
val descEditText = dialogView.findViewById<EditText>(R.id.description) //popUp pole edit field description
dialogView.addImage.setOnClickListener {
getPreviewImage.launch("image/*")
}
dialogView.addVideo.setOnClickListener {
getPreviewVideo.launch("video/*")
}
dialogView.addButton.setOnClickListener {
if (titleEditText.text.isEmpty()){
Toast.makeText(applicationContext, "add required data", Toast.LENGTH_SHORT).show()
}else{
Toast.makeText(applicationContext, "Added", Toast.LENGTH_SHORT).show()
}
}
dialog.setContentView(dialogView)
dialog.show()
}
}
Try to use a global variable for the dialogView
layout and check for the URI
existence:
class MainActivity : AppCompatActivity() {
private val home = HomeFragment()
private val player = PlayerFragment()
private val profile = ProfileFragment()
private val settings = SettingsFragment()
private var dialogView: View? = null
private val getPreviewImage = registerForActivityResult(ActivityResultContracts.GetContent(), ActivityResultCallback {
it?.let { uri ->
dialogView?.findViewById<ImageView>(R.id.imageChange)?.setImageURI(it)
} ?: run {
Log.e("MainActivity", "URI not present")
}
})
private val getPreviewVideo = registerForActivityResult(ActivityResultContracts.GetContent(), ActivityResultCallback {
it?.let { uri ->
dialogView?.findViewById<ImageView>(R.id.VideoSelect)?.setImageURI(it)
} ?: run {
Log.e("MainActivity", "URI not present")
}
})
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
val popupButton: FloatingActionButton = findViewById(R.id.fab)
val bottomNav: BottomNavigationView = findViewById(R.id.bottomNavigationView)
bottomNav.background = null
bottomNav.menu.findItem(R.id.placeholder).isEnabled = false
replaceFragment(home)
bottomNav.setOnItemSelectedListener {
when (it.itemId) {
R.id.home -> replaceFragment(home)
R.id.player -> replaceFragment(player)
R.id.profile -> replaceFragment(profile)
R.id.settings -> replaceFragment(settings)
}
true
}
popupButton.setOnClickListener {
showDialog()
}
}
private fun replaceFragment(fragment: Fragment) {
val transaction = supportFragmentManager.beginTransaction()
transaction.replace(R.id.fragment_container, fragment)
transaction.commit()
}
private fun showDialog() {
val title = RecyclerAdapter().titles
val description = RecyclerAdapter().details
val video = RecyclerAdapter().videos
val dialog = Dialog(this)
dialogView = layoutInflater.inflate(R.layout.popup, null)
val buttonImage = dialogView?.findViewById<Button>(R.id.addImage)
val titleEditText = dialogView?.findViewById<EditText>(R.id.titleEdit) //popUp edit field title
val descEditText = dialogView?.findViewById<EditText>(R.id.description) //popUp pole edit field description
dialogView?.addImage.setOnClickListener {
getPreviewImage.launch("image/*")
}
dialogView?.addVideo.setOnClickListener {
getPreviewVideo.launch("video/*")
}
dialogView?.addButton.setOnClickListener {
if (titleEditText.text.isEmpty()){
Toast.makeText(applicationContext, "add required data", Toast.LENGTH_SHORT).show()
}else{
Toast.makeText(applicationContext, "Added", Toast.LENGTH_SHORT).show()
}
}
dialog.setContentView(dialogView)
dialog.show()
}
