为了读取上面的json类型，我使用了下面给出的方法
For reading the above json type i used the method is given below
Gson gson = new Gson();
Type listType = new TypeToken<List<SpinnerMenuItems>>(){}.getType();
List<SpinnerMenuItems> selectedNetwork = gson.fromJson(gson.toJson(result.getResult()), listType);
settingDropDown(selectedNetwork);
实际上我的问题是从 json 对象中读取 json 数组，然后使用自定义适配器在列表视图中查看 json 数组.我不知道怎么读这个.
Actually my problem is to read the json array from the json object and the json array are viewed in a listview by using custom adapter. I don't know how to read this.
为了读取 json 对象，我使用了以下模型类
For reading the json object i used the following model class
public class SpinnerMenuItems {
@SerializedName("LST")
String zeroList;
@SerializedName("LST1")
String firstList;
public String getZeroList() {
return zeroList;
}
public void setZeroList(String zeroList) {
this.zeroList = zeroList;
}
public String getFirstList() {
return firstList;
}
public void setFirstList(String firstList) {
this.firstList = firstList;
}
}
上面的model类就是读取json对象里面的list.
The above model class is to read the list inside the json object.
下面的模型类是读取json对象里面的json数组
The below model class is to read the json array which is placed inside the json object
public class ListZero {
@SerializedName("IPH")
String images;
@SerializedName("OID")
String oid;
@SerializedName("OPE")
String ope;
@SerializedName("OCD")
String ocd;
@SerializedName("MIL")
String mil;
public String getMxl() {
return mxl;
}
public void setMxl(String mxl) {
this.mxl = mxl;
}
public String getMil() {
return mil;
}
public void setMil(String mil) {
this.mil = mil;
}
public String getOcd() {
return ocd;
}
public void setOcd(String ocd) {
this.ocd = ocd;
}
public String getOpe() {
return ope;
}
public void setOpe(String ope) {
this.ope = ope;
}
public String getOid() {
return oid;
}
public void setOid(String oid) {
this.oid = oid;
}
public String getImages() {
return images;
}
public void setImages(String images) {
this.images = images;
}
@SerializedName("MXL")
String mxl;
}
请帮助我如何读取放置在 json 对象中的 json 数组.就我而言，我需要读取唯一的一个 json 数组列表并在列表视图中查看该列表.如何读取json数组.
Please help me how to read the json array which is placed inside the json object. In my case i need to read the only one json array list and view the list in a listview. How to read the json array.

您可以使用 http://www.jsonschema2pojo.org/ 工具来轻松解析您的 Json 数据.
You can use the http://www.jsonschema2pojo.org/ tool to parse your Json data easily.
你的情况应该是这样的.
In your case it should be like this.
com.example.DS.java
com.example.DS.java
package com.example;
import java.util.List;
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
public class DS {
@SerializedName("LST")
@Expose
private List<LST> lST = null;
@SerializedName("LST1")
@Expose
private List<LST1> lST1 = null;
public List<LST> getLST() {
return lST;
}
public void setLST(List<LST> lST) {
this.lST = lST;
}
public List<LST1> getLST1() {
return lST1;
}
public void setLST1(List<LST1> lST1) {
this.lST1 = lST1;
}
}
com.example.Example.java
com.example.Example.java
package com.example;
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
public class Example {
@SerializedName("DS")
@Expose
private DS dS;
public DS getDS() {
return dS;
}
public void setDS(DS dS) {
this.dS = dS;
}
}
com.example.LST.java
com.example.LST.java
package com.example;
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
public class LST {
@SerializedName("OID")
@Expose
private Integer oID;
@SerializedName("OCD")
@Expose
private String oCD;
@SerializedName("OPE")
@Expose
private String oPE;
@SerializedName("IPH")
@Expose
private String iPH;
@SerializedName("MIL")
@Expose
private Integer mIL;
@SerializedName("MXL")
@Expose
private Integer mXL;
public Integer getOID() {
return oID;
}
public void setOID(Integer oID) {
this.oID = oID;
}
public String getOCD() {
return oCD;
}
public void setOCD(String oCD) {
this.oCD = oCD;
}
public String getOPE() {
return oPE;
}
public void setOPE(String oPE) {
this.oPE = oPE;
}
public String getIPH() {
return iPH;
}
public void setIPH(String iPH) {
this.iPH = iPH;
}
public Integer getMIL() {
return mIL;
}
public void setMIL(Integer mIL) {
this.mIL = mIL;
}
public Integer getMXL() {
return mXL;
}
public void setMXL(Integer mXL) {
this.mXL = mXL;
}
}
com.example.LST1.java
com.example.LST1.java
package com.example;
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
public class LST1 {
@SerializedName("OID")
@Expose
private Integer oID;
@SerializedName("OCD")
@Expose
private String oCD;
@SerializedName("OPE")
@Expose
private String oPE;
@SerializedName("IPH")
@Expose
private String iPH;
@SerializedName("MIL")
@Expose
private Integer mIL;
@SerializedName("MXL")
@Expose
private Integer mXL;
public Integer getOID() {
return oID;
}
public void setOID(Integer oID) {
this.oID = oID;
}
public String getOCD() {
return oCD;
}
public void setOCD(String oCD) {
this.oCD = oCD;
}
public String getOPE() {
return oPE;
}
public void setOPE(String oPE) {
this.oPE = oPE;
}
public String getIPH() {
return iPH;
}
public void setIPH(String iPH) {
this.iPH = iPH;
}
public Integer getMIL() {
return mIL;
}
public void setMIL(Integer mIL) {
this.mIL = mIL;
}
public Integer getMXL() {
return mXL;
}
public void setMXL(Integer mXL) {
this.mXL = mXL;
}
}
此后使用 Gson 将 json 解析为自定义模型
After this Parse json to custom model using Gson
Gson gson = new GsonBuilder().create();
Example yourModelClass = gson.fromJson(yourJsonResponse, Example.class);
从那里你可以从模型中访问任何你想要的东西.喜欢
from there you can access anything which ever you want from the model. like
DS myDSObject = yourModelClass.getDS();
List<LST> lST = myDSObject.getLST();
LST myLSTObject = lST.get(0) // 1st Item.
然后在这里你可以得到像数组数据
Then here inside array data you can get like
String oID= myLSTObject.getOID();
String oCD= myLSTObject.getOCD();
String oPE= myLSTObject.getOPE();
...... 用类似的方法可以得到其余的数据
...... in similar way you can get the rest data
