Work out the width and height of the screen or panel.

Divide both by 2.

You either know the height and width of the image or can work those out

Divide both by 2.

Take away from the screen numbers and then place.

Using the designer scripts:

B4X:

LogoSplash.HorizontalCenter = 50%x
LogoSplash.VerticalCenter = 50%y

thank you, but if I use your information, I see no picture!?

perhaps we need to subtract the width of the left panel and then do the calculation?

thanks for help

If the parent is a panel (Panel1):

B4X:

LogoSplash.HorizontalCenter = Panel1.Width / 2
LogoSplash.VerticalCenter = Panel1.Height / 2

In that cast the code @NJDude posted is correct.

If it doesn't work for you then please upload the layout file.

You should attach the WHOLE PROJECT not only the .bal file.

The problem I see is the ANCHORS, change the values to:

B4X:

Horizontal anchor = Left
Vertical anchor = Top

And change the ImageView width and Height to 200dip.

You can tweak that later of course.

You can use the anchors feature for the splash screen:

However if you set the anchors to BOTH then the view should be large enough. Otherwise it will disappear on smaller devices.
In this case you do not need to set anything in the designer script.
