Pass value from one class to another

I have 3 classes:

• AddText(extends Activity)
• Grafitti(extends MapActivity)
• MarkerOverlay

Grafitti calls AddText, and AddText opens a new Activity that gets an input from user (EditText), then when that is successful Grafitti calls MarkerOverlay.

The pr开发者_如何学Gooblem is I can't access the input in AddText. I need to use that input in MarkerOverlay, I tried creating a setter and getter but it won't work. (error)

I've tried searching the web and I think the solution is Bundle. I'm having a hard time understanding how Bundle works. Is there any other way? or any code snippet on how to use Bundle. A code snippet would really help me a lot.

Grafitti needs to start AddText via startActivityForResult() and then listen for the result via onActivityResult().

Look into startActivityForResult(Intent intent, int requestCode).
