相比json解析，Gson解析更高效簡(jiǎn)潔

先看看json解析

JSONObject object = new JSONObject(s);String succ= object.getString("success"); JSONArray barray = object.getJSONArray("list"); for (int b = 0;b<barray.length();b++){JSONObject jsonObject = barray.getJSONObject(b);String title = jsonObject.getString("title");String Startdate = jsonObject.getString("Startdate");String placeCode = jsonObject.getString("placeCode");String readType = jsonObject.getString("readType");if (jsonObject.getString("readType").equals("未讀")){}MiniNewsEntity entity1 = new MiniNewsEntity();entity1.setStartdate(Startdate);entity1.setTitle(title);entity1.setPlaceCode(placeCode);entity1.setStatus(readType);barEntityList.add(entity1); }

?

開(kāi)始Gson解析

添加Gson依賴(lài)

implementation "com.google.code.gson:gson:2.8.2"

以一下json為解析對(duì)象

{"apkPath":"http://61.145.196.120/update/ywAPP/app-release.apk","version":26,"content":"1.修復(fù)自動(dòng)更新bug"}

?

1、創(chuàng)建bean工具類(lèi)

/*** 作者：created by meixi* 郵箱：13164716840@163.com* 日期：2018/11/2 09*/ public class TestGson {private String apkPath;private String version;private String content;public String getApkPath() {return apkPath;}public void setApkPath(String apkPath) {this.apkPath = apkPath;}public String getVersion() {return version;}public void setVersion(String version) {this.version = version;}public String getContent() {return content;}public void setContent(String content) {this.content = content;} }

?

2、開(kāi)始解析

String s = "{"apkPath":"http://61.145.196.120/update/ywAPP/app-release.apk","version":26,"content":"1.修復(fù)自動(dòng)更新bug"}";

?

Gson gson = new Gson();TestGson userBean =gson.fromJson(s, new TypeToken<TestGson>() {}.getType());// TestGson userBean = gson.fromJson(s, TestGson.class);//第二種寫(xiě)法Log.i("lgq", "wwbb==" + userBean.getContent());

?

結(jié)果：11-02 09:43:53.055 18477-18477/com.tianxinyw.mapclient.liteapp I/lgq: wwbb==1.修復(fù)自動(dòng)更新bug

?

3、Gson解析數(shù)組

?

{"result":1,"count":3,"page":1,"yeCount":1,"list":[{"readType":"未讀","title":"大嶺山光順網(wǎng)吧計(jì)費(fèi)即將到期，請(qǐng)?zhí)嵝牙m(xù)費(fèi)！","Startdate":"2018-11-16 23:59:59.0","placeCode":"1897"},{"readType":"未讀","title":"大嶺山玩不夠網(wǎng)吧計(jì)費(fèi)即將到期，請(qǐng)?zhí)嵝牙m(xù)費(fèi)！","Startdate":"2018-11-16 23:59:59.0","placeCode":"1887"},{"readType":"未讀","title":"大朗盛佳網(wǎng)吧計(jì)費(fèi)即將到期，請(qǐng)?zhí)嵝牙m(xù)費(fèi)！","Startdate":"2018-11-03 00:00:00.0","placeCode":"4701"}]}

?

3/1創(chuàng)建數(shù)組單元類(lèi)

public class list {private String readType;private String title;private String Startdate;public String getReadType() {return readType;}public void setReadType(String readType) {this.readType = readType;}public String getTitle() {return title;}public void setTitle(String title) {this.title = title;}public String getStartdate() {return Startdate;}public void setStartdate(String startdate) {Startdate = startdate;} }

內(nèi)部類(lèi)寫(xiě)法

public static class DataBean implements Serializable {private int id;private int device_id;

?

private List<DataBean> data;

?

3/2創(chuàng)建總數(shù)據(jù)元素類(lèi)（可只取部分?jǐn)?shù)據(jù)）

?

public class OutsideEntity {private String yeCount;private List<com.tianxinyw.mapclient.entitys.list> list = new ArrayList<>();public String getYeCount() {return yeCount;}public void setYeCount(String yeCount) {this.yeCount = yeCount;}public List<com.tianxinyw.mapclient.entitys.list> getList() {return list;}public void setList(List<com.tianxinyw.mapclient.entitys.list> list) {this.list = list;} }

?

3/3開(kāi)始解析json

Gson gson = new Gson();OutsideEntity userBean =gson.fromJson(s, new TypeToken<OutsideEntity>() {}.getType());List<list> userBeanList = userBean.getList();//單獨(dú)獲取數(shù)組集合Log.i("lgq", "re==logtest=====" +userBeanList.get(2).getTitle()+"...."+userBean.getYeCount());

結(jié)果是：11-02 13:41:47.907 14188-14188/com.tianxinyw.mapclient.liteapp I/lgq: re==logtest=====大朗盛佳網(wǎng)吧計(jì)費(fèi)即將到期，請(qǐng)?zhí)嵝牙m(xù)費(fèi)！....1

總結(jié)
