如何在android的动态微调器中获取选定项id值

我在android中创建了动态微调器，显示url中的

json

数据。我在微调器中正确设置了数据，但我得到了所选项目的id

我该怎么做

设置微调器值的代码是：

私有void setSpinData（）{

---

如何获取所选微调器项目的

cartype\u id

？

创建一个

MyModel

如下

public class MyModel
{
    String cartype_id,type,rate_type,rate_in;

    public String getCartype_id() {
        return cartype_id;
    }

    public void setCartype_id(String cartype_id) {
        this.cartype_id = cartype_id;
    }

    public String getType() {
        return type;
    }

    public void setType(String type) {
        this.type = type;
    }

    public String getRate_type() {
        return rate_type;
    }

    public void setRate_type(String rate_type) {
        this.rate_type = rate_type;
    }

    public String getRate_in() {
        return rate_in;
    }

    public void setRate_in(String rate_in) {
        this.rate_in = rate_in;
    }
}

然后为模型类创建一个数组列表

现在像这样从微调器中获取所选项目

public class MyModel
{
    String cartype_id,type,rate_type,rate_in;

    public String getCartype_id() {
        return cartype_id;
    }

    public void setCartype_id(String cartype_id) {
        this.cartype_id = cartype_id;
    }

    public String getType() {
        return type;
    }

    public void setType(String type) {
        this.type = type;
    }

    public String getRate_type() {
        return rate_type;
    }

    public void setRate_type(String rate_type) {
        this.rate_type = rate_type;
    }

    public String getRate_in() {
        return rate_in;
    }

    public void setRate_in(String rate_in) {
        this.rate_in = rate_in;
    }
}
