Ability to view text in each class

Recently, I program for the Android platform. I have a questio开发者_JAVA百科n about the text.

Is there any way to display the text without using the XML?

I also want the text to be able to show in each class.

If you're asking if you can replace the text of anything programatically, yes you can. Usually, you have a setText method you can use for that. I'd advise you to read the tutorial and the javadoc to know more about this.
