2,067 PointsCapturing Price from an Edit Text
Any ideas on how to do this? I am trying to input the value into a SQL database. Again, examples are appreciated.

2,067 PointsBen strikes again! lol Yeah - no, I can retrieve a String from an Edit text. I'm trying to capture "price" from an edit text (i.e., User please input fee: ______ ).
I'm trying to format the Edit text so the User can only input USD (ie ($2.50) ) and I will store that value in my database (which only takes Integers or Reals).
I feel like I need to do a conversion like what I did with the checkbox boolean value (i.e. storing the value as a 1 or 0) but I'm a bit confused as to how to do it. I've read that BigDecimal is the way to go but I don't know how to correctly use that method. I've been looking online but I can't seem to find any code examples which to me is a bit odd considering most forms must capture "price" or "fee" (I would think).

Treehouse TeacherTo get the String value from an EditText, do the following:
String inputText = mEditText.getText().toString();
If I misunderstood the question just let me know. :)

Treehouse TeacherAh! If only it were the simple answer. :)
First, I think you will want to choose one of the number inputTypes. Then you'll need to add a TextWatcher to the field to format and check it. Here's an example: http://www.blog.nathanhaze.com/inserting-currency-in-a-edit-text-field-with-text-watcher-android/
With the string you build there you could use BigDecimal which is good for storing monetary values. BigDecimal is a lot like
doubleexcept it's a full-fledged object that requires a constructor. You can insert BigDecimal values for REAL values in the db.For a code example, check out the code from my recent workshop on SQLite.
