从上面的JSON结构我想在 BattingDetail 数组的第一个索引中更新运行变量。无法解决此问题。任何人都知道帮助我解决这个问题。

如果您正在使用http://developer.android.com/reference/org/json/JSONObject.html

中的JSONObject

从BattlingDetail JSONArray获取相应的JSONObject。或者根据您的需要迭代阵列。删除当前值。换一个。

JSONObject object = array.getJSONObject[0];
object.remove("runs");
object.put("runs", 100);

如何更新特定的JSON值？
