无法解析数组上的符号可绘制

Question

我在Android Studio上有一段代码，如下所示：

public static void getData() {
        List<Information> data = new ArrayList<>();
        int[] icons = (R.drawable.ic_bookmark1, R.drawable.ic_bookmark2);
    }

我在网上收到了错误：

 int[] icons = (R.drawable.ic_bookmark1, R.drawable.ic_bookmark2);

错误说：

Can't resolve Symbol Drawable. 

还有错误说：

 Can't resolve Symbol ic_bookmark2;

截图： 我已将我的图标放在res文件夹中

代码和错误

这是我的.java文件的完整代码。

我认为问题在于括号的使用，你应该使用括号。

int[] icons = (R.drawable.ic_bookmark1, R.drawable.ic_bookmark2);

应该是

int[] icons = {R.drawable.ic_bookmark1, R.drawable.ic_bookmark2};
