How can I change the font color, size and button color from a Java file in Eclipse, not from an XML file?

For font size you can write it as 

tv.setTextSize(20.0f);

For font color you can write it as 

tv.setTextColor(Color.BLUE);

For button background color you can write it as 

btn.setBackgroundColor(Color.CYAN);

  • well have a look at this... i just googled and i found this... I think it is possible to change for spinner items too. Please take a look at this http://stackoverflow.com/questions/4989817/set-the-textsize-to-a-text-in-spinner-in-android-programatically – Lavanya Aug 23 '11 at 09:13

  • You can refer to this question: http://stackoverflow.com/questions/4880413/text-color-of-a-closed-spinner – Onuray Sahin Aug 23 '11 at 12:32

In the "Inherited XML Attributes" paragraph of the official documentation you can see either XML attributes (that you can change from XML) or related methods (which you can use in your Java code).

Others already posted answers on how to do it in Java, but I guess these could help you as well.
