Question

我试图做一些与众不同的事情。我有一个添加个人资料页面，用户可以在其中添加多个个人资料。我想在主页上将这些配置文件表示为圆圈（ImageButtons）。

非常类似：

因此，当用户保存个人资料时，如何将这些圈子中的一个添加到此水平滚动视图中？我希望创建的圆圈在创建的客户名称的第一个字母中包含一个字母。我想这需要我已经创建了所有26个字母的字母，但这没有问题。

有关如何执行此操作的任何建议？如果我不清楚，我很抱歉，我很乐意发布更多代码或澄清任何内容。我使用的数据库是Firebase。我正在运行最新版本的Android Studio。

非常感谢任何帮助，为人们欢呼！

}

编辑（我尝试过的）： 我厌倦了其他按钮作为改变图像的实验，因为我无法想出直接创建它。

 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main17);

        ImageView view = (ImageView) findViewById(R.id.imageView3);
        view.setOnClickListener(new View.OnClickListener() {
            public void onClick(View view) {
                ImageView imageView = (ImageView) view;
                assert(R.id.imageView3 == imageView.getId());
                Integer integer = (Integer) imageView.getTag();
                integer = integer == null ? 0 : integer;
                switch(integer) {
                    case R.drawable.circlesambergrey2:
                        imageView.setImageResource(R.drawable.bell);
                        imageView.setTag(R.drawable.bell);
                        break;
                    case R.drawable.bell:
                    default:
                        imageView.setImageResource(R.drawable.circlesambergrey2);
                        imageView.setTag(R.drawable.circlesambergrey2);
                        break;}
                }
            });
        }

我还认为用户可以使用旋转器中正确的字母选择图像按钮。这就是我目前正在尝试的！欢呼声。

单击“保存”按钮时，在单独的活动中创建ImageButton？
