You can set HintLabelLargeOffsetX, HintLabelSmallOffsetY and HintLabelSmallOffsetX.

Make sure to call B4XFloatTextField.Update after modifying these fields.

No, obviously; I just wanted to say that that image you posted may not be adequate (for privacy reasons)

(I searched for that name)

don't solve because HintLabelSmallOffsetY move only the label but i want to move the textfield
with B4A i do

B4X:

 fld.TextField.Padding = Array As Int (5dip,5dip,0dip,0dip)

but in B4I is not supported

What exactly do you want to move? Why aren't you doing it in the designer script?

You can move the control with fld.mBase.SetLayoutAnimated.
You will need to do it in Page_Resize event

Sorry Erel,
but this is what I need

1) If B4XFloatTextField is Multiline, B4i uses a TextView.

In this case it's possible https://developer.apple.com/documentation/uikit/uitextview/1618619-textcontainerinset

B4X:

Dim no As NativeObject = B4XFloatTextField1.TextField
no.RunMethod("setTextContainerInset:", Array (no.MakeEdgeInsets (8, 0, 8, 0)))

Of course, change standard values.

2) If B4XFloatTextField is Singleline, B4i uses a TextField.
In this case it's possible to use leftView and rightView properties.
For example:

B4X:

#If OBJC
- (void) setInsets : (UITextField *) textField : (int) paddingLeft : (int) paddingRight
    {
    textField.leftView      = [[UIView alloc] initWithFrame: CGRectMake (0, 0,  paddingLeft,  0)];
    textField.rightView     = [[UIView alloc] initWithFrame: CGRectMake (0, 0,  paddingRight, 0)];
    textField.leftViewMode  = UITextFieldViewModeAlways;
    textField.rightViewMode = UITextFieldViewModeAlways;
}
#End If

Call

B4X:

Dim no As NativeObject = Me
no.RunMethod ("setInsets:::", Array (B4XFloatTextField2.TextField, 50, 75))
