How can I set the initial text of editor?

[JohnQue]

I wrote a post and I wanted to modify this.
But, I think there wasn't a method which can solve this problem.
I want to set the initial text when I want to modify this post.
I mean, when I click the modify button then, post content's is saved in String object and
android start writeActivity and add pre-saved text to the editor but I can't.

How can I solve this?
