Hi all,
I need urgent help with a simple selection I am having difficulty
with.
I am trying to return a value of a Double called startPosition, where
trackName is equal to a name of a string.
The query doesnt seem to be returning anything, here is the code from
my DbAdapter.
Java:
public Cursor getStartLatitude(String trackname) throws
SQLException {
Cursor mCursor =
mDb.query(true, DATABASE_TABLE3, new String[] {KEY_ROWID3,
KEY_TRACKNAME,
KEY_STARTPOSITION}, KEY_TRACKNAME + "=" +
"'kingsav'",
null, null, null, null, null);
if (mCursor != null) {
mCursor.moveToFirst();
}
return mCursor;
}
And here is my code from the Java code that passes in the value and
reads it to a textview. Note above, I have used a static value for
testing purposes.
Java:
private void loadTrackInfo()
{
Cursor b = mDbHelper.getStartLatitude(TrackName);
if(b.moveToFirst())
{
Double startLocation =
b.getDouble(b.getColumnIndex(mDbHelper.KEY_STARTPOSITION));
selectedTracktv.setText("Active Track: "+startLocation);
}
}
