It seems that the root panel can't be pushed up into an negativ Y offset anymore.

Are you doing it programmatically?

Yes with:

B4X:

pg_KeyboardStateChanged (Height As Float)

It only happens to TextFields at the Bottom when the page has to be pushed into an negative Y offset

Please reproduce it in a small project and upload it. It might be related to the Xcode version.

I still need some time with a small example but while trying to find the mistake we figured out that neither

B4X:

pg_KeyboardStateChanged (Height As Float)

nor

B4X:

Page.RootPanel.CalcRelativeKeyboardHeight(Height)

calculates the right height. You can check this with

Code:

-(void)keyboardWasShown:(NSNotification *)notification {
    
    NSDictionary* info = [notification userInfo];
    
    CGSize keyboardSize = [[info objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;
    
  
    NSLog(@"keyboard size %@",NSStringFromCGSize(keyboardSize));
            
}

or have a look at http://www.idev101.com/code/User_Interface/sizes.html

You need to understand how this method works: https://www.b4x.com/android/forum/threads/calcrelativekeyboardheight-example.64054/#content

My colleague is on vacation so I write about our problems via this account.

1st problem: pg.RootPanel.SetLayoutAnimated
In some modules the page is no longer shifted to the negative y area. The problem has only existed since the update.

2nd problem: Private Sub pg_KeyboardStateChanged (Height As Float)does not return the correct keyboard height.

It never returned the keyboard height.

Check this: https://www.b4x.com/android/forum/threads/calcrelativekeyboardheight-example.64054/#content

For the first issue, you should prepare a small project that demonstrates it.
