1. Create one model in that model generate getter and setter method of required variable.

public static String query_select_all = "SELECT * FROM " + TABLENAME;

public ArrayList<model> DataSingleton()
 {
ArrayList<visible_Model> visibleSections  = new  ArrayList<visible_Model>();


    Cursor cursor = database_helper.rawQuery(query_select_all, null);

    if (cursor.moveToFirst()) {
        do {
            visible_Model model = new visible_Model();

            model.setMessage(cursor.getString(cursor
                    .getColumnIndex(COLUMN_FROM_MSG)));

            visibleSections.add(model);

        } while (cursor.moveToNext());

    }
    return visibleSections;
}

Here,In above I create model name as a visile_model and use setMessage method.at last I add that model into arraylist visibleSections
