sendToView

The view is bound after it is ready to use, which is after onStart. This prevents you from accessing the view before the layout is inflated or fragments are commited.

The presenter #onCreate is called before your Activity#onCreate().

Thank you for your answer

use sendToView before onStart
use getView other state
is right?

It depends. I use getView when the view calls a method of my presenter and I can synchronously update the view. If anything is async I'd use sendToView.

Alternatively you can write some kind of render method. Update you model in the presenter and call render which is the only place the view gets updated. Like this:

private val count = 0

override fun onAttachView(view: MyView) {
    render()
}

override fun onButtonPressed() {
    count++
    render()
}

private fun render() {
    if (view == null) return // view not attached

    view.updateCount(count)
    // ...
}

i think you use sendToView becasue of not call setContetView()
if i call bindView after setContentView() or inflate()
getView() can work
i think...
