java - 循环重写的简单方法

Question

是否有更简单的方法来编写此代码以使我的 ImageView 不可见？我希望我可以使用某种类型的 for 循环。我也是编程新手，因此在您的回答中，您能否解释一下循环是如何工作的，以便我可以在将来的引用中使用它？另外，如何将 15 个 ImageView 分配给 1 个数组？

        iv_1.setVisibility(View.INVISIBLE);
        iv_2.setVisibility(View.INVISIBLE);
        iv_3.setVisibility(View.INVISIBLE);
        iv_4.setVisibility(View.INVISIBLE);
        iv_5.setVisibility(View.INVISIBLE);
        iv_6.setVisibility(View.INVISIBLE);
        iv_7.setVisibility(View.INVISIBLE);
        iv_8.setVisibility(View.INVISIBLE);
        iv_9.setVisibility(View.INVISIBLE);
        iv_10.setVisibility(View.INVISIBLE);
        iv_11.setVisibility(View.INVISIBLE);
        iv_12.setVisibility(View.INVISIBLE);
        iv_13.setVisibility(View.INVISIBLE);
        iv_14.setVisibility(View.INVISIBLE);
        iv_15.setVisibility(View.INVISIBLE);
        iv_16.setVisibility(View.INVISIBLE);
        iv_17.setVisibility(View.INVISIBLE);

Answer 1

将 iv_xx 对象放入列表或数组中，然后使用循环遍历数组:

ArrayList<IVType> ivList = new ArrayList<>();
// use ivList.add() to add each object to the list.
for (IVType iv: ivList)
{
  iv.setVisibility(View.INVISIBLE);
}
