代码：

JSONObject abc = json.getJSONObject("tast_start_time");
Log.e("LOCATYION",json.getJSONArray("tast_start_day").toString());
Log.e("msg",abc.toString());
Log.e("msg",abc.getJSONObject("300").toString());

当我尝试记录jsonarray时，它的效果非常好，但是当我尝试获得300的jsonobject时，它会给我一个例外。

Answer 1

物业的价值＆＃34; 300＆＃34;不是JSON对象，它是一个字符串。尝试像

这样的东西

Log.e("msg",abc.getString("300"));

Answer 2

JSON对象abc包含字符串条目＆＃34; 5 am＆＃34;在key＆＃34; 300＆＃34;，而不是另一个JSON对象。所以它应该是：

Log.e("msg",abc.getString("300"));

Answer 3

使用abc.getString("300");获取字符串值。

Answer 4

你试图获取jsonobject，但它是一个json字符串，这就是你收到错误的原因。

Log.e("msg",abc.getJSONObject("300").toString());

以下替换

Log.e("msg",abc.getString("300"));

注意： -

1. {} denote jsonobject 2. [] denote jsonarray 3. "value":"name" denote string

在java.lang.String类型的300上的值5am无法转换为JSONObject
