Question

i want to get the value from the cursor without the SimpleCursorAdapter part.here is the code

public Cursor queueAll(){
  String[] columns = new String[]{KEY_ID, KEY_CONTENT1, KEY_CONTENT2,KEY_CONTENT3};
  Cursor cursor = sqLiteDatabase.query(MYDATABASE_TABLE, columns,
    null, null, null, null, null);
  return cursor;
 }

and the activity side code

cursor = mySQLiteAdapter.queueAll();

       from = new String[]{SQLiteAdapter.KEY_ID, SQLiteAdapter.KEY_CONTENT1, SQLiteAdapter.KEY_CONTENT2, SQLiteAdapter.KEY_CONTENT3};
       int[] to = new int[]{R.id.id, R.id.text1, R.id.text2,R.id.text3};
       cursorAdapter =
       new SimpleCursorAdapter(this, R.layout.row, cursor, from, to);
       listContent.setAdapter(cursorAdapter); 

       while(!cursor.isAfterLast())
       {
           String tilt = cursor.getString(cursor.getColumnIndex(SQLiteAdapter.KEY_CONTENT1));
           String pkg = cursor.getString(cursor.getColumnIndex(SQLiteAdapter.KEY_CONTENT3));
           if(tilt.equals("LEFT"))
           {
           Log.v("LEFT",pkg);
           }
           else if(tilt.equals("RIGHT"))
           {
               Log.v("RIGHT",pkg);
           }
           cursor.moveToNext();
       }

i am getting the pkg value correct.but i want to get the values directly from the cursor while removing SimpleCursorAdapter part the code doesn’t work.
any help would be appreciated 🙂

You can get values without declaring adapters. Adapters are need if you want to show the data in the list widgets. So your can be the following:

cursor = mySQLiteAdapter.queueAll();

if (cursor == null) {
//check if there are errors or query just return null
}
if (cursor.moveToFirst()) {
       while(!cursor.isAfterLast())
       {
           String tilt = cursor.getString(cursor.getColumnIndex(SQLiteAdapter.KEY_CONTENT1));
           String pkg = cursor.getString(cursor.getColumnIndex(SQLiteAdapter.KEY_CONTENT3));
           if(tilt.equals("LEFT"))
           {
           Log.v("LEFT",pkg);
           }
           else if(tilt.equals("RIGHT"))
           {
               Log.v("RIGHT",pkg);
           }
           cursor.moveToNext();
       }
}
