Hello,
Sometimes, when using a spinner, you want to manage its size and the font of the displayed text.
To do that you need to do 3 actions (I do that change on the Android spinner example : http://developer.android.com/guide/tutorials/views/hello-spinner.html)
1. Create a spinnertext.xml in your layout folder and define how the spinner’s title has to be displayed
2. Change your spinner size in your main.xml (where your spinner is defined)
3. Change your spinner declaration in your activity
