java - 通过循环动态赋值 - Android - 通过java编程

Question

这里是定制的圆形图像的列表。需要通过循环动态赋值。

            RoundedImageView img23 = (RoundedImageView) findViewById(R.id.avatar23);
            img23.setImageResource(R.mipmap.avatars_male_28);

            RoundedImageView img24 = (RoundedImageView) findViewById(R.id.avatar24);
            img24.setImageResource(R.mipmap.avatars_male_29);

            RoundedImageView img25 = (RoundedImageView) findViewById(R.id.avatar25);
            img25.setImageResource(R.mipmap.avatars_male_30);

            for (i = 1;i>25; i++){
                j=(String) i;

                //need a loop that dynamically sets img**2** (any number)
                img<j>.setImageResource(R.mipmap.avatars_male_30);
            }

Answer 1

而不是创建 RoundedImageView img1、RoundedImageView img2、RoundedImageView img3 ...

只需创建一个RoundImageView的ArrayList:

ArrayList<RoundedImageView> list = new ArrayList<RoundedImageView>();
list.add((RoundedImageView) findViewById(R.id.avatar1));
list.add((RoundedImageView) findViewById(R.id.avatar2));
list.add((RoundedImageView) findViewById(R.id.avatar3));
