Thank you.
I have another question about cursor.
I have inserted a ContentValue like this:
final ContentResolver cr = context.getContentResolver();
ContentValue values = new ContentValues();
values.put("title", "new title");
values.put("x", 10);
Uri result = cr.insert(CONTENT_URI ,
values);
But why when I do my query and then getColumn, I get
java.lang.IllegalArgumentException: column 'x' does not exist
Cursor c = cr.query(CONTENT_URI,
new String[] { "title" }, "title=?",
new String[] { "new title" }, null);
if (c.getCount() >0) {
// get an exception here:
int xColumn = c.getColumnIndexOrThrow("x");
}
