我正在执行一项任务，如果之后在onCreate中命中了URL，我将把所有URL存储在Click中的对象的哈希映射库中。我正在访问特定的对象及其工作正常。但是在状态后如果按返回按钮然后再次返回片段状态的URL统计信息仅是什么建议呢？
我的JSON响应：
[
{
"id": 1404,
"cameraId": 1184,
"onUrl": "",
"offUrl": "",
"statusUrl": "",
"type": "Strobe",
"statusOnMessage": "P1 = on",
"statusOffMessage": "P1 = off",
"onSuccessMessage": "P1 = on",
"offSuccessMessage": "P1 = off"
},
{
"id": 1405,
"cameraId": 1184,
"onUrl": "",
"offUrl": "",
"statusUrl": "",
"type": "Light",
"statusOnMessage": "P2 = on",
"statusOffMessage": "P2 = off",
"onSuccessMessage": "P2 = on",
"offSuccessMessage": "P2 = off"
}
]
**访问此URL后，我将所有数据存储在哈希图中，并在单击事件中访问该URL，但再次返回相同的片段后，此状态仅在预览状态下返回** 代码：
