I am trying to make a header and it is going to have 4 or 5 buttons…I am not sure yet.
The text of those buttons will vary in length and also the different devices will have different widths, and also there are the horizontal and vertical views for each device. So I am not sure what my background images should be in terms of height and width so everything fits nicely on the screen.
What is the recommended or best practice way of handling this?
Thanks!!
You need to read the android docs, specifically Designing for Multiple Screens.
Perhaps Supporting Multiple Screens as well.
It will take you through what you need to know/do to set up and support those devices you wish to.
