我想对阵列使用GSON.

我看了一些示例,但无法使其与我的代码一起使用.
Using GSON to parse a JSON array.

我收到此错误消息：预期为字符串,但在行1列为BEGIN_ARRAY

在该项目中,我遵循的原始教程涉及解析Json Objects.

我的杰森：

[{   "nID": "25",   "Title": "angry guy",   "body": "fhjk gjj"}, {   "nID": "24",   "Title": "25 mobile",   "body": "25 test tes"}, {   "nID": "8",   "Title": "new post 4",   "body": "sdfsdf sdfsdf"}, {   "nID": "7",   "Title": "new post",   "body": "sdf sdf sdfsdf"}]

我的代码：

String finalJson = buffer.toString();            JsONArray parentArray = new JsONArray(finalJson);            List<ExerciseModel> exerciseModelList = new ArrayList<>();            Gson gson = new Gson();            for(int i=0; i<parentArray.length(); i++){                JsONObject finalObject = parentArray.getJsONObject(i);                ExerciseModel exerciseModel = gson.fromJson(finalObject.toString(), ExerciseModel.class);                exerciseModelList.add(exerciseModel);            }            return exerciseModelList;

我的模特：

    public class ExerciseModel {    private int nID;    private String Title;    private String body;    public int getNID() {        return nID;    }    public voID setNID(int nID) {        this.nID = nID;    }    public String getTitle() {        return Title;    }    public String toString() {        return this.Title;    }    public voID setTitle(String Title) {        this.Title = Title;    }    public String getbody() {        return body;    }    public voID setbody(String body) {        this.body = body;    }}

提前致谢

解决方法:

你的课应该是

public class ExerciseModel{  private String nID;  public String getNID() { return this.nID; }  public voID setNID(String nID) { this.nID = nID; }  private String Title;  public String getTitle() { return this.Title; }  public voID setTitle(String Title) { this.Title = Title; }  private String body;  public String getbody() { return this.body; }  public voID setbody(String body) { this.body = body; }}

GSON代码的代码应为：

String Json = "[{ \"nID\": \"25\", \"Title\": \"angry guy\", \"body\": \"fhjk gjj\" }, { \"nID\": \"24\", \"Title\": \"25 mobile\", \"body\": \"25 test tes\" }, { \"nID\": \"8\", \"Title\": \"new post 4\", \"body\": \"sdfsdf sdfsdf\" }, { \"nID\": \"7\", \"Title\": \"new post\", \"body\": \"sdf sdf sdfsdf\" }]";Type listofTestObject = new Typetoken<List<ExerciseModel>>() {}.getType();ArrayList<ExerciseModel> models = new Gson().fromJson(Json, listofTestObject);System.out.println(models.get(0).getTitle());
