问题
I have a RelativeLayout with a button inside it. Once the user clicks on that button, I would like to change the background of the parent view (RelativeLayout). I know I can do this by storing the parent view in a variable or setting a tag on the button, but I'd lime to avoid that (I have very good reasons for not wanting this). Isn't there a way to just access the parent view from the button itself?

Try View.getParent():
Button yourBtn = (Button) findViewById(R.id.your_btn);
RelativeLayout yourRelLay = (RelativeLayout) yourBtn.getParent();
