使用适配器

Question

我从json中的服务器获取数据

我正在使用自定义适配器并存储在recyclerview上显示此数据

我正在使用Getter Setter类来获取和设置值 这是我的Getter Setter等级

public class UserData {
String email,firstName;
List<String> companies;

public UserData(String email, String firstName, List<String> companies) {
    this.email = email;
    this.firstName = firstName;
    this.companies = companies;
}

public String getEmail() {
    return email;
}

public void setEmail(String email) {
    this.email = email;
}

public String getFirstName() {
    return firstName;
}

public void setFirstName(String firstName) {
    this.firstName = firstName;
}

public List<String> getCompanies() {
    return companies;
}

public void setCompanies(List<String> companies) {
    this.companies = companies;
}

}

通过使用适配器类，我能够显示电子邮件和firstName，但无法从公司获取数据 获取数据的代码

final UserData rowItem = rowItems.get(position);
holder.tvName.setText(rowItem.getfirstName());
holder.tvEmail.setText(rowItem.getemail());

我想显示公司名单

holder.tvCompanies.setText（strCompaniesName）; 我用它来获取用户的公司名称

strCompaniesName = "";
        for (int i = 0; i < rowItem.getCompanies().size(); i++) {

            Log.i("Value of element " + i, rowItem.getCompanies().get(i));
            if (i == 0)
                strCompaniesName = rowItem.getCompanies().get(i);
            else
                strCompaniesName = strCompaniesName + ", \n " + rowItem.getCompanies().get(i);
        }
