將圖片id快速加到陣列

public void imgIdtoArray() {
        ArrayList Icon = new ArrayList<>();
        
        //假設有50張圖
        for (int i = 0; i < 50; i++) {
            //每張圖片的檔名 → no_1,no_2,no_3.....
            String name = "no_" + i; 
            ballIcon.add(getResources()
               .getIdentifier(name, "drawable", getPackageName()));
        }
    }
