Java 方法从数组列表返回

Question

我想知道这甚至可能吗？以及执行此类操作的最佳方法是什么：

    private int NotifCountBg(int countstyle) {
    return new int[]{
            R.drawable.count_bevel,
            R.drawable.count_blue,
            R.drawable.count_green,
            R.drawable.count_orange,
            R.drawable.count_pink,
            R.drawable.count_purple,
            R.drawable.count_red,
            R.drawable.count_gray
         }[countstyle];
    }

Answer 1

您可以为数组使用常量：

private static final int[] STYLES = new int[]{ R.drawable.count_bevel, R.drawable.count_blue, 
    R.drawable.count_green, R.drawable.count_orange, R.drawable.count_pink,
    R.drawable.count_purple, R.drawable.count_red, R.drawable.count_gray };

private int notifCountBg(final int countstyle) {
    return STYLES[countstyle];
}

Answer 2

使用枚举：摆脱索引、数组和类型化 (int) 常量。
