Android java循环对象列表

我的代码连接到一个Api，获取所有Json值并将它们全部存储在对象列表

resultClass

中。如何循环浏览列表并显示对象的所有名称属性

这是我正在使用的代码。JSON值与方法调用一起作为名为

object

的参数发送。然后循环并获取所有对象，并将它们存储在列表中

public void onResponse(JSONObject object) {
        Log.i("gw2Log", "Json Response" + object);

        resultClass resultClass = new resultClass();

        try {
            resultClass.setCount(object.getInt("count"));
            resultClass.setPage(object.getInt("page"));
            resultClass.setLast_page(object.getInt("last_page"));
            resultClass.setTotal(object.getInt("total"));
            JSONArray list = new JSONArray(object.getString("results"));

            for (int i = 0; i < resultClass.getTotal(); i++) {
                JSONObject resultsObject = list.getJSONObject(i);

                resultClass.setData_id(resultsObject
                        .getInt("data_id"));
                resultClass.setName(resultsObject
                        .getString("name"));
                resultClass.setRarity(resultsObject
                        .getInt("rarity"));
                resultClass.setRestriction_level(resultsObject
                        .getInt("restriction_level"));
                resultClass.setImg(resultsObject
                        .getString("img"));
                resultClass.setType_id(resultsObject
                        .getInt("type_id"));
                resultClass.setSub_type_id(resultsObject
                        .getInt("sub_type_id"));
                resultClass.setPrice_last_changed(resultsObject
                        .getString("price_last_changed"));
                resultClass.setMax_offer_unit_price(resultsObject
                        .getInt("max_offer_unit_price"));
                resultClass.setMin_sale_unit_price(resultsObject
                        .getInt("min_sale_unit_price"));
                resultClass.setOffer_availability(resultsObject
                        .getInt("offer_availability"));
                resultClass.setSale_availability(resultsObject
                        .getInt("sale_availability"));
                resultClass.setSale_price_change_last_hour(resultsObject
                        .getInt("sale_price_change_last_hour"));
                resultClass.setOffer_price_change_last_hour(resultsObject
                        .getInt("offer_price_change_last_hour"));
            }

        } catch (JSONException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        for(int i = 0; i < resultClass.total; i++) {
            Log.i("gw2Log", resultClass.name[i]);
        }
    }

在查找解决方案并检查实际错误时，它会说它需要和数组，但给出了一个字符串

Log.i（“gw2Log”，resultClass.name[i]）

当我循环这个日志调用时，
Log.I（“gw2Log”，resultClass.name）显示上次对象名称属性及其循环量

编辑：
应请求包括my resultClass.java：

public class resultClass {

好吧，有几件事我很确定：

Tomer Shemesh是对的，您在每次迭代中都覆盖了
resultClass
对象

您想用
resultClass
中的普通变量制作数组，这样就可以实际存储多个项

关于您遇到的错误：

它发生在较低的for循环中，您希望在其中记录名称，对吗

resultClass.name
是一个字符串变量，它只包含一个字符串。您试图通过说出类似于
resultClass.name[i]
的语句来从数组中获取字符串。为此，您需要将其定义为一个字符串数组，包含多个字符串，如
publicstring[]name，并在构造函数中使用给定的函数初始化它，如
name=newstring[cap]。或者改用
ArrayList
，它动态增长，但使用自己的getter和setter，而不是数组的简单名称[index]函数

很抱歉，我不想在这里编写正确的代码，因为几乎整个过程都需要重写，但我希望这能帮助您自己重写它。

尝试类似的方法

public void onResponse(JSONObject object) {
    Log.i("gw2Log", "Json Response" + object);

    resultClass resultClass = new resultClass();

    try {
        resultClass.setCount(object.getInt("count"));
        resultClass.setPage(object.getInt("page"));
        resultClass.setLast_page(object.getInt("last_page"));
        resultClass.setTotal(object.getInt("total"));
        JSONArray list = new JSONArray(object.getString("results"));

        for (int i = 0; i < resultClass.getTotal(); i++) {
            JSONObject resultsObject = list.getJSONObject(i);
            MyObject temp = new MyObject();
            temp.setData_id(resultsObject
                    .getInt("data_id"));
            temp.setName(resultsObject
                    .getString("name"));
            temp.setRarity(resultsObject
                    .getInt("rarity"));
            temp.setRestriction_level(resultsObject
                    .getInt("restriction_level"));
            temp.setImg(resultsObject
                    .getString("img"));
            temp.setType_id(resultsObject
                    .getInt("type_id"));
            temp.setSub_type_id(resultsObject
                    .getInt("sub_type_id"));
            temp.setPrice_last_changed(resultsObject
                    .getString("price_last_changed"));
            temp.setMax_offer_unit_price(resultsObject
                    .getInt("max_offer_unit_price"));
            temp.setMin_sale_unit_price(resultsObject
                    .getInt("min_sale_unit_price"));
            temp.setOffer_availability(resultsObject
                    .getInt("offer_availability"));
            temp.setSale_availability(resultsObject
                    .getInt("sale_availability"));
            temp.setSale_price_change_last_hour(resultsObject
                    .getInt("sale_price_change_last_hour"));
            temp.setOffer_price_change_last_hour(resultsObject
                    .getInt("offer_price_change_last_hour"));
            resultClass.addObject(temp);
        }

    } catch (JSONException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    for(int i = 0; i < resultClass.total; i++) {
        Log.i("gw2Log", resultClass.getObject(i).name);
    }
}

首先创建一个新对象，类似于MyObject

public class MyObject {

public int data_id;
public String name;
public int rarity;
public int restriction_level;
public String img;
public int type_id;
public int sub_type_id;
public String price_last_changed;
public int max_offer_unit_price;
public int min_sale_unit_price;
public int offer_availability;
public int sale_availability;
public int sale_price_change_last_hour;
public int offer_price_change_last_hour;

public int getData_id() {
    return data_id;
}

public void setData_id(int data_id) {
    this.data_id = data_id;
}

public String getName() {
    return name;
}

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

public int getRarity() {
    return rarity;
}

public void setRarity(int rarity) {
    this.rarity = rarity;
}

public int getRestriction_level() {
    return restriction_level;
}

public void setRestriction_level(int restriction_level) {
    this.restriction_level = restriction_level;
}

public String getImg() {
    return img;
}

public void setImg(String img) {
    this.img = img;
}

public int getType_id() {
    return type_id;
}

public void setType_id(int type_id) {
    this.type_id = type_id;
}

public int getSub_type_id() {
    return sub_type_id;
}

public void setSub_type_id(int sub_type_id) {
    this.sub_type_id = sub_type_id;
}

public String getPrice_last_changed() {
    return price_last_changed;
}

public void setPrice_last_changed(String price_last_changed) {
    this.price_last_changed = price_last_changed;
}

public int getMax_offer_unit_price() {
    return max_offer_unit_price;
}

public void setMax_offer_unit_price(int max_offer_unit_price) {
    this.max_offer_unit_price = max_offer_unit_price;
}

public int getMin_sale_unit_price() {
    return min_sale_unit_price;
}

public void setMin_sale_unit_price(int min_sale_unit_price) {
    this.min_sale_unit_price = min_sale_unit_price;
}

public int getOffer_availability() {
    return offer_availability;
}

public void setOffer_availability(int offer_availability) {
    this.offer_availability = offer_availability;
}

public int getSale_availability() {
    return sale_availability;
}

public void setSale_availability(int sale_availability) {
    this.sale_availability = sale_availability;
}

public int getSale_price_change_last_hour() {
    return sale_price_change_last_hour;
}

public void setSale_price_change_last_hour(int sale_price_change_last_hour) {
    this.sale_price_change_last_hour = sale_price_change_last_hour;
}

public int getOffer_price_change_last_hour() {
    return offer_price_change_last_hour;
}

public void setOffer_price_change_last_hour(int offer_price_change_last_hour) {
    this.offer_price_change_last_hour = offer_price_change_last_hour;
}
}

然后让你的resultClass看起来像这样

public void onResponse(JSONObject object) {
    Log.i("gw2Log", "Json Response" + object);

    resultClass resultClass = new resultClass();

    try {
        resultClass.setCount(object.getInt("count"));
        resultClass.setPage(object.getInt("page"));
        resultClass.setLast_page(object.getInt("last_page"));
        resultClass.setTotal(object.getInt("total"));
        JSONArray list = new JSONArray(object.getString("results"));

        for (int i = 0; i < resultClass.getTotal(); i++) {
            JSONObject resultsObject = list.getJSONObject(i);
            MyObject temp = new MyObject();
            temp.setData_id(resultsObject
                    .getInt("data_id"));
            temp.setName(resultsObject
                    .getString("name"));
            temp.setRarity(resultsObject
                    .getInt("rarity"));
            temp.setRestriction_level(resultsObject
                    .getInt("restriction_level"));
            temp.setImg(resultsObject
                    .getString("img"));
            temp.setType_id(resultsObject
                    .getInt("type_id"));
            temp.setSub_type_id(resultsObject
                    .getInt("sub_type_id"));
            temp.setPrice_last_changed(resultsObject
                    .getString("price_last_changed"));
            temp.setMax_offer_unit_price(resultsObject
                    .getInt("max_offer_unit_price"));
            temp.setMin_sale_unit_price(resultsObject
                    .getInt("min_sale_unit_price"));
            temp.setOffer_availability(resultsObject
                    .getInt("offer_availability"));
            temp.setSale_availability(resultsObject
                    .getInt("sale_availability"));
            temp.setSale_price_change_last_hour(resultsObject
                    .getInt("sale_price_change_last_hour"));
            temp.setOffer_price_change_last_hour(resultsObject
                    .getInt("offer_price_change_last_hour"));
            resultClass.addObject(temp);
        }

    } catch (JSONException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    for(int i = 0; i < resultClass.total; i++) {
        Log.i("gw2Log", resultClass.getObject(i).name);
    }
}

那么你的回答应该是这样的

public void onResponse(JSONObject object) {
    Log.i("gw2Log", "Json Response" + object);

    resultClass resultClass = new resultClass();

    try {
        resultClass.setCount(object.getInt("count"));

        resultClass.setLast_page(object.getInt("last_page"));
        resultClass.setTotal(object.getInt("total"));
        JSONArray list = new JSONArray(object.getString("results"));

        for (int i = 0; i < resultClass.getTotal(); i++) {
            JSONObject resultsObject = list.getJSONObject(i);
            MyObject temp = new MyObject();
            temp.setData_id(resultsObject
                    .getInt("data_id"));
            temp.setName(resultsObject
