Question

我是关于android编程的新手，今天我想将数据添加到另一个模型类

并且在另一个类模型中是相同的模型

但我不知道添加它

例如

我的第一个模特

public class TelephoneModel {
 private List<DataBean> data;
 public List<DataBean> getData() {
        return data;
    }

    public void setData(List<DataBean> data) {
        this.data = data;
    }

    public static class DataBean {
        private String id;
        private String name;

 public String getId() {
            return id;
        }

        public void setId(String id) {
            this.id = id;
        }

public String getName() {
            return name;
        }

        public void setName(String name) {
            this.name = name;
        }
}

和我的第二个模特

public class TelephoneDetailModel {
private List<DataBean> data;
  public List<DataBean> getData() {
        return data;
    }

    public void setData(List<DataBean> data) {
        this.data = data;
    }

    public static class DataBean {
  private String id;
        private String name;

 public String getId() {
            return id;
        }

        public void setId(String id) {
            this.id = id;
        }

        public String getName() {
            return name;
        }

        public void setName(String name) {
            this.name = name;
        }
}
}

我在

中有数据

List<TelephoneModel.DataBean> databeans = new ArrayList<>;
List<TelephoneDetailModel.DataBean> dataDetailbeans = new ArrayList<>;

我希望将数据databeans添加到dataDetailbeans

如何添加，请为我举例，

谢谢！

Answer 1

试试这个

List<TelephoneDetailModel.DataBean> databeans = new ArrayList();

        TelephoneDetailModel.DataBean dataBean = new TelephoneDetailModel.DataBean();
        dataBean.setId("1");
        dataBean.setName("PREM");
        databeans.add(dataBean);


        TelephoneDetailModel.DataBean model1 = new TelephoneDetailModel.DataBean();
        model1.setId("2");
        model1.setName("PREM2");
        databeans.add(model1);


        TelephoneDetailModel.DataBean model2 = new TelephoneDetailModel.DataBean();
        model2.setId("3");
        model2.setName("PREM3");
        databeans.add(model2);


        TelephoneDetailModel.DataBean model3 = new TelephoneDetailModel.DataBean();
        model3.setId("4");
        model3.setName("PREM4");
        databeans.add(model3);


        for (int i = 0; i < databeans.size(); i++) {

            Log.e("ID", databeans.get(i).getId());
            Log.e("NAME", databeans.get(i).getName());
        }

输出

com.example.user33.demoapplication E/ID: 1
com.example.user33.demoapplication E/NAME: PREM
com.example.user33.demoapplication E/ID: 2
com.example.user33.demoapplication E/NAME: PREM2
com.example.user33.demoapplication E/ID: 3
com.example.user33.demoapplication E/NAME: PREM3
com.example.user33.demoapplication E/ID: 4
com.example.user33.demoapplication E/NAME: PREM4

试试这个

public class TelephoneDetailModel {

    private List<DataBean> data;

    public List<DataBean> getData() {
        return data;
    }

    public void setData(List<DataBean> data) {
        this.data = data;
    }

    public static class DataBean {
        private String id;
        private String name;

        public DataBean() {

        }

        public DataBean(String id, String name) {
            this.id = id;
            this.name = name;
        }

        public String getId() {
            return id;
        }

        public void setId(String id) {
            this.id = id;
        }

        public String getName() {
            return name;
        }

        public void setName(String name) {
            this.name = name;
        }
    }
}

现在要在arraylist尝试此
中添加数据

List<TelephoneDetailModel.DataBean> databeans = new ArrayList();
databeans.add(new TelephoneDetailModel.DataBean("6","NEW NAME"));

你好这样改变你的模型类（它使用起来非常简单）

- ＆GT; TelephoneModel

from rpy2.robjects import r
def decompose(series, frequency, s_window, **kwargs):
    df = pd.DataFrame()
    df['date'] = series.index
    s = [x for x in series.values]
    length = len(series)
    s = r.ts(s, frequency=frequency)
    decomposed = [x for x in r.stl(s, s_window, **kwargs).rx2('time.series')]
    df['observed'] = series.values
    df['trend'] = decomposed[length:2*length]
    df['seasonal'] = decomposed[0:length]
    df['residual'] = decomposed[2*length:3*length]
    return df

}

- ＆GT; TelephoneDetailModel

            if (m.find()) {
                String matched = m.group(0);
                int addToArray = Integer.parseInt(matched);
                playerRanking[i] = addToArray;
                System.out.println(i);
            }

}

- ＆GT;你的活动

public class TelephoneModel {

private String id;
private String name;

public TelephoneModel(String id,String name) {
    this.id=id;
    this.name=name;
}

public String getId() {
    return id;
}

public void setId(String id) {
    this.id = id;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

如果有任何问题可以随意问我......

TelephoneModel类和TelephoneDetailModel中的DataBean不同，您无法将Datadean添加到另一个列表
