我想使用Gson 将其转换为自定义对象类型的List

这是我的 POJO

public class RazorpayNetbanking {
@Expose
private String name;
@Expose
private String value;

public String getName() {
    return this.name;
}

public void setName(String name) {
    this.name = name;
}

public String getValue() {
    return this.value;
}

public void setValue(String value) {
    this.value = value;
}
}

【问题讨论】：

Json 不是有效的。
1) 您的 JSON 无效。我想你只展示了一部分。 2）不清楚你想得到什么结果。
@DKV 我知道，但这来自外部 api
有没有我可以在不手动解析的情况下转换它
首先，您需要一个有效的 json。然后只有你可以解析它。

标签： java android json kotlin gson

【解决方案1】：

由于您无法猜测密钥，因此您应该对其进行迭代：

val json: JsonObject // assuming
json.keySet().forEach {  key ->
    val value = json.get(key).asString
    // add to list (key, value)
}

这仅适用于键，但我想你明白了。

【解决方案2】：

您应该使用地图，并且可以轻松地将其转换为列表。

编辑：我不知道 gson 是否支持配对列表。也许它可以工作......
