问题
Hey guy's First of all thanks for reading this. I'm having trouble to find a way to change my EditText when I loose focus to it. I would like it to be greyed out when this happens, but I don't want it to be disabled because the user can touch it and edit the text later.
Anyone?
Greetings!

You can set different colors to the text based on an OnFocusChangeListener
Another option is to set a style in xml. See this question for details: Android: change style when focused
To change the opacity, use setAlpha. In this answer I show it how to do it in an animation: Two questions about custom app ui's and AlphaAnimation
