# 假设有以下数据
```
[{
	"CarId": 1,
	"Time": "2017-11-26 16:58:11",
	"Cost": 10
}, {
	"CarId": 1,
	"Time": "2017-11-26 16:58:19",
	"Cost": 20
}, {
	"CarId": 1,
	"Time": "2017-11-26 16:58:24",
	"Cost": 30
}, {
	"CarId": 1,
	"Time": "2017-11-26 16:58:28",
	"Cost": 40
}]
```

# 以下类
```
public class GetCarAccountRecord {

/**
     * CarId : 1
     * Time : 2017-11-26  04:58:11
     * Cost : 10
     */

private int CarId;
    private String Time;
    private int Cost;

public int getCarId() {
        return CarId;
    }

public void setCarId(int CarId) {
        this.CarId = CarId;
    }

public String getTime() {
        return Time;
    }

public void setTime(String Time) {
        this.Time = Time;
    }

public int getCost() {
        return Cost;
    }

public void setCost(int Cost) {
        this.Cost = Cost;
    }
}

```

# 使用 Gson 解析，然后遍历输出
```
List<GetCarAccountRecord> list = new Gson().fromJson(jsonObject.optJSONArray("ROWS_DETAIL").toString(), new TypeToken<List<GetCarAccountRecord>>() {}.getType());

for (GetCarAccountRecord getCarAccountRecord : list) {
    Log.i("小车编号：", String.valueOf(getCarAccountRecord.getCarId()));
    Log.i("充值金额：", String.valueOf(getCarAccountRecord.getCost()));
}
```
