How to format an EditText's numeric value on unfocus (or at all!?) in Android to use commas
<p>I'm trying to take the user input, which may or may not have a comma in it, and put a comma in the correct places upon the user deselecting the field (or at all, if that's not possible).</p>

<p>I would also like to know how I can subtract the commas to make the number just an integer.</p>

<p>Thanks in advance for your help!</p>
