My app crashes without an error message when I try to show a DialogFragment, I have absolutely no Idea why this is happening.
When I say it crashes, I mean that the UI of the app freezes and no action is done anymore.
In my dialog I want to display a ViewPager, which displays two more fragments inside the dialog.
My code:
Dialog:
@AndroidEntryPoint
class SetSiteDialog : DialogFragment() {
private var _binding: DialogSetSiteBinding? = null
private val binding get() = _binding!!
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setStyle(STYLE_NORMAL, R.style.AppTheme_FullScreenDialog)
}
override fun onStart() {
super.onStart()
dialog?.window?.setLayout(
ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.MATCH_PARENT
)
}
override fun onCreateView(
inflater: LayoutInflater,
container: ViewGroup?,
savedInstanceState: Bundle?
): View {
_binding = DialogSetSiteBinding.inflate(inflater, container, false)
binding.viewPager.adapter = PagerAdapter(this)
TabLayoutMediator(binding.tabLayout, binding.viewPager) { tab, position ->
tab.text = when (position) {
PagerAdapter.PAGE_SEARCH -> getString(R.string.dialog_location_specification_option_search)
PagerAdapter.PAGE_FREE_INPUT -> getString(R.string.dialog_location_specification_option_self)
else -> ""
}
}.attach()
return binding.root
}
}
