如何用好Gson让json使用更方便之生成篇

在以往项目中比较常用的无非就是解析Json或者生成Json

首先咱们先使用类库

implementation 'com.google.code.gson:gson:2.8.5'   注:本人Android studio版本比较高

实例解析篇:

//然后生成POJO类  //我暂时命名为ObjectInfo ，注:需要养成习惯添加比较注解  以下是类代码

public class ObjectInfo {
    //头像
    private String img;
    //年龄
    private String age;
    //性别#0:男1:女
    private String sex;
    //是否已婚#0:未婚1：已婚
    private String isMarried;
    //积分
    private String integral;
    //余额
    private String balance;

    public String getImg() {
        return img;
    }

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

    public String getAge() {
        return age;
    }

    public void setAge(String age) {
        this.age = age;
    }

    public String getSex() {
        return sex;
    }

    public void setSex(String sex) {
        this.sex = sex;
    }

    public String getIsMarried() {
        return isMarried;
    }

    public void setIsMarried(String isMarried) {
        this.isMarried = isMarried;
    }

    public String getIntegral() {
        return integral;
    }

    public void setIntegral(String integral) {
        this.integral = integral;
    }

    public String getBalance() {
        return balance;
    }

    public void setBalance(String balance) {
        this.balance = balance;
    }
}

//现在我们解析开始,以下是toJson全部代码

/***
 * 使用Gson生成Json类Demo
 */
public class ToGsonActivity extends BaseActivity implements View.OnClickListener {

    //返回键空间
    private ImageView backIv;
    //标题控件
    private TextView titleTv;
    //打印信息显示控件
    private TextView printTv;

    @Override
    public int initLayout() {
        return R.layout.activity_gson;
    }

    @Override
    public void initView() {
        backIv = findViewById(R.id.include_back_iv);
        titleTv = findViewById(R.id.include_title_tv);
        printTv = findViewById(R.id.gson_print_tv);

    }

    @Override
    public void initData() {
        titleTv.setText("Json生成");
        ObjectInfo info=new ObjectInfo();
        info.setImg("http://image.biaobaiju.com/uploads/20180802/03/1533152912-BmPIzdDxuT.jpg");
        info.setSex("0");
        info.setAge("18岁");
        info.setIsMarried("1");
        info.setIntegral("8888");
        info.setBalance("188.88");
        String jsonStr = toJson(info);
        printTv.setText(jsonStr);

        backIv.setOnClickListener(this);
    }

    private String toJson(ObjectInfo info) {
        //生成json格式数据
        String jsonStr = new Gson().toJson(info, ObjectInfo.class);
        return jsonStr;
    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.include_back_iv:
                finish();
                break;
        }

    }
}
