SimpleCursorAdapter from SQLiteDatabase Cursor not displaying properly in Spinner adapter

i'm trying to connect query a database and display the results in a Spinner. below is what i have so far. unfortunately the spinner only displays the last row that should have been returned from the query. so from the example above, only "Elvis Presley" shows up in the list. i've tried using "Cursor.moveToFirst()" (as you can see) but that doesn't do it.

i realized that i rebuild and update the database everytime i open it. i'm doing this on purpose for now.

You are putting values in Content Values.

ContentValues cv = new ContentValues();
cv.put(smsDbSchema.CustomerSchema.COLUMN_NAME, "Charles Keith Gilliam");
..
..
..

Anf finally u write a insert statement. So, to my understanding essentially u put only one value in the ContentValues since others are overwritten.

You can also pull the db file using DDMS and open using SQLite browser to make that all entires are there in the DB

You should try inserting each content value lik this. Pls try this so that all entries are made in the db.

cv.put(smsDbSchema.CustomerSchema.COLUMN_NAME, "Charles Keith Gilliam");
cv.put(smsDbSchema.CustomerSchema._ID, "7585684317298");
mDb.insert(smsDbSchema.CustomerSchema.TABLE_NAME, null, cv);

cv.put(smsDbSchema.CustomerSchema.COLUMN_NAME, "Jarrod Martin");
cv.put(smsDbSchema.CustomerSchema._ID, "0298437598745");
mDb.insert(smsDbSchema.CustomerSchema.TABLE_NAME, null, cv);
