android 英文单词升序排序（Collections.sor

如果只是单纯的字符串比较把SignBean类对象换成String对象道理都是一样的；

//定义数据源
 List<SignBean> list = new ArrayList<>();
       
        SignBean signBean = new SignBean();
        signBean.setName("abc");
        signBean.setValue("1");
        list.add(signBean);

        SignBean signBean1 = new SignBean();
        signBean1.setName("abb");
        signBean1.setValue("2");
        list.add(signBean1);

        SignBean signBean2 = new SignBean();
        signBean2.setName("cb");
        signBean2.setValue("3");
        list.add(signBean2);
//排序
  Collections.sort(list, new Comparator<SignBean>() {
            @Override
            public int compare(SignBean o1, SignBean o2) {
//拿到2个bean类中的name字符串进行比较，android中字符串比较是比较的ASCLL码
//compareTo（） 字符串比较
                int i = o1.getName().compareTo(o2.getName());
                if (i > 0) {
                    return 1;
                } else {
                    return -1;
                }
            }
        });
for (int i = 0; i <list.size() ; i++) {
            Log.e("tyl","name="+list.get(i).getName());
            Log.e("tyl","value="+list.get(i).getValue());
        }
//排序完成 打印数据结果：
        name=abb
        value=2
        name=abc
        value=1
        name=cb
        value=3

SignBean 类代码：

public class SignBean  {
    private String name;
    private String value;
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }

    public String getValue() {
        return value;
    }
    public void setValue(String value) {
        this.value = value;
    }
}
