Android Question Problems with IME_HeightChanged Transparent StatusBar Using B4XPages

Johan Hormaza · Feb 28, 2021

IME_HeightChanged is not responding when I use transparent StatusBar using B4XPages as explained by @Erel here https://www.b4x.com/android/forum/threads/transparent-statusbar-using-b4xpages.125562/
My code is:

B4X:

Sub Activity_Create(FirstTime As Boolean)
    Dim jo As JavaObject
    Dim window As JavaObject = jo.InitializeContext.RunMethod("getWindow", Null)
    window.RunMethod("addFlags", Array(Bit.Or(0x00000200, 0x08000000)))
    Activity.Height = Activity.Height + 80dip
    Dim pm As B4XPagesManager
    pm.Initialize(Activity)
    IME.Initialize("IME")
    IME.AddHeightChangedEvent
    CorrectHeight = 100%y
    Wait For IME_HeightChanged (NewHeight As Int, OldHeight As Int)
    CorrectHeight = NewHeight
    HeightChangedFired = True
End Sub

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

This is a known limitation of the height changed event. It is the same as the issue with full screen activities (https://www.b4x.com/android/forum/t...-keyboard-with-the-ime-library.14832/#content).

So there is no solution?

It is important to have this method working since the design that is needed is this

How could it be countered?

I'm not familiar with a workaround. Sorry.

Maybe this library can help: https://www.b4x.com/android/forum/threads/ime2-library.121451/#content

I also faced this last week with transparent status bar. Apparently, it is a known limitation that has been around for years and has not been corrected. What I did was to set the status bar color to match the current background so it at least looks close to what is in the design. Apart from that, I don't think you will find any workaround until you remove the transparent status bar feature.

You can use this to set status bar colour

B4X:

Sub SetStatusBarColor
    Dim p As Phone
    If p.SdkVersion >= 21 Then
        Dim jo As JavaObject
        jo.InitializeContext
        Dim window As JavaObject = jo.RunMethodJO("getWindow", Null)
        window.RunMethod("addFlags", Array (0x80000000))
        window.RunMethod("clearFlags", Array (0x04000000))
        If selectThemeColor Then
            window.RunMethod("setStatusBarColor", Array(0xFFFFFF)
        Else
            window.RunMethod("setStatusBarColor", Array(Colors.White))
        End If
    End If
End Sub

Thanks friend, but I need the screen to be extended since it has a map and the idea is to see it on the entire screen with good aesthetics since applications such as BEAT, UBER etc. They got it.

Thanks Erel, but I already tried.

Yeah, they do, but you'll notice that Uber takes you to another screen that does not have a transparent status bar (at least, that's how it works on my phone) even Google maps.

Maybe there is a way to turn off transparent status bar on a new page and reactivate it when you get back to the map page.

I tried that too but nothing.
It will be time to add an Activity
