如何在 Android 中正确解析这个 JSON 文件？

我需要来自 1 号塔的所有对象（那里可能有不同数量的工作日）以及这些工作日中不同数量的时间范围。

我已经成功地使用了像这样的静态方法

JSONObject jArray = ja.getJSONObject("towers").getJSONObject("tower1") .getJSONObject("tuesday").getJSONObject("11:45-12:20");

然后我使用 getString() 方法获得了 value1 的值。

但它们需要是动态的，因为有很多可能性。

"towers": {
"tower 1": {
  "tuesday": {
    "07:30-11:30": {
      "value1": "test value 1",

      "value3": "test value 3"
    },

如果您的 json 字符串键是动态的，那么您可以将其解析为：

JSONObject root = new JSONObject(yourString);
// get towers JSONObject
JSONObject towers = root.getJSONObject("towers"); 
// get all Towers name from towers JSONObject 

JSONArray alltowerslist=towers.names();

for(int i=0;i<alltowerslist.length();i++){
   // get sub towers from towers
   JSONObject sub_towers = towers.getJSONObject(alltowerslist.optString(i)); 
   // get days list from sub_towers
    JSONArray alldayslist=sub_towers.names();
    for(int j=0;j<alldayslist.length();j++){
       // get days from  sub_towers
        JSONObject days_json = sub_towers.getJSONObject(alldayslist.optString(j)); 

         // get time json JSONObject from days_json
        JSONArray alltimeslist=days_json.names();
        for(int k=0;k<days_json.length();k++){
       // get time from  sub_towers
        JSONObject time_json = days_json.getJSONObject(alltimeslist.optString(k));

        // now get all value1 from time_json
        JSONArray allvalelist=time_json.names();
        for(int l=0;l<time_json.length();l++){
           String str_value = time_json.optString(allvalelist.optString(l));
          }   
        }
    }
}
