【问题描述】：
您好，我正在制作安卓应用程序。我在我的应用程序中使用 json 解析。首先这是我的 json 响应
{
"Data": {
"headerText": "Revolution",
"productStartingPrice": "$38.78",
"sizeList": [
{
"textUpper": "Revolution for (Pink)",
"textLower": "$38.78",
"packList": [
{
"textUpper": "3 DOSES",
"textLower": "$38.78",
}
{
"textUpper": "6 DOSES",
"textLower": "$71.60",
}
]
},
{
"textUpper": "Revolution for (Blue)",
"textLower": "$46.92",
"packList": [
{
"textUpper": "3 DOSES",
"textLower": "$46.92",
}
{
"textUpper": "6 DOSES",
"textLower": "$79.56",
}
{
"textUpper": "12 DOSES",
"textLower": "$137.27",
}
]
}
]
},
"Status": 1,
"Message": "",
"UserMessage": ""
}
现在我正在使用自定义警报对话框来加载 sizelist 数组和另一个用于 packlist 数组的 dailog。现在我想要的是当用户从 sizelist 中选择（粉红色）然后在第二个 dailog 中我想从 packlist 中显示 3 剂和 6 剂，当用户选择（蓝色）时我想显示 3 剂、6 剂、12 剂。现在我只得到最后两项（蓝色）6 剂，12 剂。谁能帮我解决这个问题？

【问题讨论】：
-
你需要在你的 sizelist modal 类中有一个 packlist 类型的数组列表
-
是的，我已经有了
-
@VivekMishra 你能帮忙吗
-
您能否突出显示您从第一个列表中选择的代码
-
检查我的适配器..请
