I've been banging my head on this problem for a few hours, and I think
it's time that I ask for help. This is my first serious attempt at
making an app, and I've got a situation where I want to pull a list of
strings from a database to present in a Spinner. During my earlier
stages of development, I had a fixed list in the strings.xml file, but I
realized that I may want to modify the list via the web at a later time,
so I moved to a database solution for it. I've got the database side of
things squared away, and I've been working on a content provider since
last night.
At this point, I know the content provider is successfully querying data
from the target table and returning it to the Spinner, but all I get are
blank lines in the Spinner instead of the strings. See
http://www.badlucksoft.com/blank_spinner.png .
Here's the code that I currently have linking the content provider to
the spinner:
Spinner spinner = (Spinner) findViewById(R.id.myspinner);
String []projection = new String [] {
"_id","label_strings"
};
String [] c = new String[] {"label_strings"};
int [] i = {R.id.myspinner};
Uri uri = "my.content.provider.uri";
Cursor managedCursor = managedQuery(uri,projection,null,null,null);
SimpleCursorAdapter sca = new
SimpleCursorAdapter(this,android.R.layout.simple_spinner_item,managedCursor,projection,i);
spinner.setAdapter(sca);
I've been changing around the parameters for instantiating
SimpleCursorAdapter trying to get this working, including setting the
"from" and "to" parameters to null and other values. Those experiments
always resulted in either an exception or even less than what I'm
getting now (as in an empty spinner).
Can anyone deduce what I'm doing wrong based on this information, and if
not, what else do you need me to provide?
Thank you,
Raymond
