TtPopOverHandler
class TtPopOverHandler
Shows a given Fragment above all other views in application.
The position of the fragment is determined by the anchor view and can be adjusted relative to it. See Request for details. Actual position of the fragment is updated every time the anchor view changes its position or size.
Intended usage:
class SomeFragment() : Fragment() {
private val viewModel by viewModels()
private var popOverHandler: TtPopOverHandler? = null
fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
viewModel.popOverState
.map { it?.toPopOverRequest() }
.observe(viewLifecycleOwner) { request ->
popOverHandler?.dismissPopOver(receiveOnDismissCallback = false)
popOverHandler = null
request?.let {
popOverHandler = TtPopOverHandler.showOrRestorePopOver(
fragment = this@SomeFragment,
anchorView = viewBinding.anchorView,
request = it,
onDismissListener = { viewModel.onPopOverDismissed() } // onPopOverDismissed() sets popOverState to null
)
}
}
}
fun doSomethingElse() {
viewModel.dismissPopOver() // dismissPopOver() sets popOverState to null
}
