4,601 PointsInitializing the CrystalBall Object
Hi!
I had a question about the Simple Refactoring video for the Crystal Ball app.
I understand why we wouldn't want to initialize the CrystalBall object within the setOnClickListener method, but could we initialize it just one level up in the onCreate method (rather than outside it as suggested in the video)?
Thanks!

2,230 PointsThat really depends. If you are going to use the mCrystalBall outside the onCreate method then you can't. But if you are going to use it in that method only you can do it.General rule of thumb is that if several methods in that class accesses it you declare it at class, if only the method has use for it you declare them in methods. Since our CrystalBall application as far as I remember doesn't have any other method so far you can do it inside onCreate method. (Can't remember the end project though.)
