Android Reformat Date in View Binder

Question

Here's what i'm trying to do, i've got a viewbinder and i want to reformat the date in here and set the text. I don't know what i'm doing wrong but i get a ton of warning and it just locks up. Here's the code:

  private class CustomViewBinder implements ViewBinder {

    @Override
    public boolean setViewValue(View view, Cursor cursor, int columnIndex) {

        if (columnIndex == cursor.getColumnIndex(StatusData.KEY_CHARTING_DATE)) {
            String date = cursor.getString(columnIndex);
            DateFormat dateFormat = android.text.format.DateFormat.getDateFormat(getActivity());
            String formatedDate = dateFormat.format(date);

             TextView tv = (TextView) view;
             tv.setText(formatedDate);
            return true;
        }
}

Warnings:

"but i get a ton of warning and it just locks up" - It would help if you showed us the warnings — Karakuri, Jun 13 '13 at 15:18
Ok. Pretty sure you're passing in an invalid parameter in the `dateFormat.format()`. What value is being passed in there. What is it's format? — Don, Jun 13 '13 at 15:25
ok, looking at the return of the function my answer was wrong so i removed it. I agree with @Don . You should check what comes out of the cursor. and i cannot find an overload of the method `format` that receives a string — Diogo Bento, Jun 13 '13 at 15:40
@jcaruso I've added an answer. Please let me know if this works for you. — Don, Jun 13 '13 at 15:42

You're passing in an illegal parameter to the dateFormat.format(). It should be a Date object. See the docs for other valid parameters.

ok i used this to create the object http://stackoverflow.com/questions/7177012/how-to-convert-string-to-date-object – jcaruso Jun 13 '13 at 15:53
That should work. If not, you could try `DateFormat.parse(String)`. It returns a `java.text.DateFormat` object. Just note that, the docs say parsing for it is lenient. Which means that, depending on your string you may or may not get the desired result. – Don Jun 13 '13 at 15:59
After testing it i do get what i want "06/13/2013" – jcaruso Jun 13 '13 at 16:02
Awesome. However, I might still try to use `android.text.format.DateFormat` so that you don't have to worry about time zones and locale. – Don Jun 13 '13 at 16:03
I know its taboo to ask but can you look at http://stackoverflow.com/questions/17075824/android-fragment-with-viewbinder – jcaruso Jun 13 '13 at 16:03
Haha It's not taboo. I enjoy being able to help other people out. I'll take a look at it. – Don Jun 13 '13 at 16:04
It should be fine since the date thats being put into the database is from their device right? – jcaruso Jun 13 '13 at 16:04
