Android Question Minimum pixels for views?

[Graeme Tacon]

Is there a minimum number of pixels that should be used for each view (i.e. for a seekbar, minimum is 10pixels height) ?

I'm using the holo theme and adding views with code (doesn't seem to work correctly using the designer). On my SGS3, all the views look great, but on other devices, they don't look so good. The seekbar is a good example - the 'circle' is squared off top and bottom and doesn't sit in the centre of the 'line'.

I am adding them using %x and %y for height and width, so I would have thought that should be ok.

Which problem did you encounter with the designer?

If you add them with the designer then you can test your layout with the UI Cloud. SeekBar height should be the default height which is 30.

I was using the Holo dark theme. Panels added in the designer come up as 'white', whereas, adding them via code, they appear black (which is what I wanted).

In holo light theme, panels are the same colour, added by designer or code.

Make sure that the designer color is DEFAULT. It will then use the default color based on the theme.

Thanks Erel - that works for panels, but what about buttons ? I have the same problem with them.

Unless you changed the buttons drawable they will use the default style based on the device theme.
