Android Question B4XPages - IME problems with fixed navigation bar

[Alexander Stolte]

If the App starts with a hidden navigation bar then, all is ok, if i show it. But if i start the app with a displayed navigation bar and hide it then, then the root page is not resizing.

Start with hidden navigation bar

Start with shown navigation bar

Private Sub IME_HeightChanged (NewHeight As Int, OldHeight As Int)
    Root.Height = NewHeight
    Panel1.Top = NewHeight - Panel1.Height
End Sub

This is not a standard Android feature.
Is the IME_HeightChanged event raised?

Is the IME_HeightChanged event raised?

Yes, the NewHeight is higher then the OldHeight

This is not really related to B4XPages. You will get the same behavior without it.

If you want to manage this case then you will need to change the activity height based on the NewHeight value.

Put this Activity.Height = NewHeight to the IME_HeightChanged sub in the Main Activity:

Sub IME_HeightChanged (NewHeight As Int, OldHeight As Int)
    Activity.Height = NewHeight
    B4XPages.GetManager.RaiseEvent(B4XPages.GetManager.GetTopPage, "IME_HeightChanged", Array(NewHeight, OldHeight))
End Sub

This fix it
