資料庫有變更，測試之前先更新資料庫，修改了DBHelper.java中

        public static void createTable_bills(SQLiteDatabase db) {
            try {
                db.execSQL("CREATE TABLE bills("
                        +" id INTEGER PRIMARY KEY, "
                        +" acctitemid INTEGER," 
                        +" fee INTEGER, "
                        +" userid INTEGER, "
                        +" date TEXT, "
                        +" time TEXT, "
                        +" desc TEXT "
                        +");");
                Log.v(LOG_TAG, "Create table bills ok");
            } catch(Exception e) {
                Log.v(LOG_TAG, "Create table bills err, table exists");
            }
        }

 

ScrollView是一種可以滑動的控制元件。在一個螢幕顯示不了全部內容時，可以使用此類，不過沒有發現在這裡是什麼作用

使用了相對佈局，而不是線性佈局
