      } 
     ] 
} 
}

以上JSON数据从服务器，以及如何阅读的JSON阵列读取JSON阵列的问题。

我的用于读取JSON数据模型类是

public class SpinnerRootObject { 
    @SerializedName("DS") 
    SpinnerMenuItems ds; 
    public SpinnerMenuItems getDs() { 
     return ds; 
    } 

    public void setDs(SpinnerMenuItems ds) { 
     this.ds = ds; 
    } 
} 

public class SpinnerMenuItems 
{ 
    @SerializedName("LST") 
    ListZero zeroList; 
    @SerializedName("LST1") 
    String firstList; 

    public ListZero getZeroList() { 
     return zeroList; 
    } 

    public void setZeroList(ListZero zeroList) { 
     this.zeroList = zeroList; 
    } 

    public String getFirstList() { 
     return firstList; 
    } 

    public void setFirstList(String firstList) { 
     this.firstList = firstList; 
    } 
} 

public class ListZero { 

    @SerializedName("IPH") 
    String images; 
    @SerializedName("OID") 
    String oid; 
    @SerializedName("OPE") 
    String ope; 
    @SerializedName("OCD") 
    String ocd; 
    @SerializedName("MIL") 
    String mil; 
    @SerializedName("MXL") 
    String mxl; 

    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; 
    } 
}

上面的代码是用于读取JSON模型类。

用于从服务器读取JSON的代码是

Gson gson = new Gson(); 
        SpinnerRootObject spinnerRootObject = gson.fromJson(result.getResult(), SpinnerRootObject.class); 
        settingDropDown((List<SpinnerRootObject>) spinnerRootObject);

在使用时发生由导致异常的上述方法：java.lang.IllegalStateException：预期BEGIN_OBJECT但BEGIN_ARRAY位于第1行第15栏路径。我不知道如何读的JSON数组中给出的JSON数据

我需要的JSON数组列表数据传递到自定义适配器

public void settingDropDown(List<SpinnerRootObject> selectedNetwork) 
{ 
    customAdapter = new Fragment_DTH_Main_Spinner_Adapter 
      (getActivity(),R.layout.fragment_dth_main_spinner_items,R.id.serviceName,selectedNetwork); 
    selectMenu.setAdapter(customAdapter); 
}

请帮我如何从JSON获得JSON数组反对

你从来没有告诉我们你想用JSON数据做什么，但我会建议只是使用simpleJSON。 –

https://www.learn2crack.com/2013/10/android-asynctask-json-parsing-example.html –

有些数据是整数，所以需要改变这个类

public class ListZero { 

    @SerializedName("IPH") 
    String images; 
    @SerializedName("OID") 
    int oid;  // do this integer 
    @SerializedName("OPE") 
    String ope; 
    @SerializedName("OCD") 
    String ocd; 
    @SerializedName("MIL") 
    int mil; // do this integer 
    @SerializedName("MXL") 
    int mxl; // do this integer 

    //getter setter ... do modify getter and setter of oid,mil and mxl accordingly.. 
    }
