Question

如何在Android中正确解析此JSON文件？

我需要所有的对象，比如塔1（那里可能有不同的工作日）以及那些工作日的不同时间段。

我已成功使用静态方法，如

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

然后我使用getString（）方法得到value1的值。

但他们需要充满活力，因为有很多种可能性。

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

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));
          }   
        }
    }
}
