Android Question Tabhost stealing focus (Lollipop)

Have you tried to set the focus with EditText.RequestFocus?

Create a sub that sets the focus. Call it with CallSubDelayed from TabHost_TabChanged event.

It's a known bug of TabHost.

In Explorer.bas of my File Explorer class, I added this comment:
'If your activity contains a TabHost, add these lines before the call to Explorer:
' Dim r As Reflector
' r.Target = TabHost1
' r.RunMethod2("setDescendantFocusability", 0x00060000, "java.lang.int") 'FOCUS_BLOCK_DESCENDANTS
'And these lines after:
' r.RunMethod2("setDescendantFocusability", 0x00040000, "java.lang.int") 'FOCUS_AFTER_DESCENDANTS
' TabHost1.RequestFocus
'That will prevent the TabHost from stealing the focus (a known bug, still not fixed in Android 4.0.3).

Hope that helps.

Thanks for your replies.

Erel, the tab-changed event doesn't seem to be triggered when the bluetooth scan happens or when the focus is put into the scrollview. Only when switching between tabs.

Informatix, yeah that code seems to work. But I have no idea where to put it, since the focus is stolen when the barcode scanner does it's scan. I'm not technically calling anything when the problem occurs.

And I'm not using the serial/asyncstreams to connect via bluetooth since the scanners seem to pair/connect fine on their own. I can't get the Serial to connect to these scanners anyway, but that's a different problem for another thread.
