我无法获得JSON数组的数组长度.当我使用length(); 方法不起作用,它在Netbeans中显示为红色下划线
这是源代码
try {
JSONObject myjson = JSONObject.fromObject(practiceInfoByUsername);
//JSONArray nameArray = myjson.names();
final JSONArray jar = myjson.getJSONArray("_types");
for(int i=0; i<jar.length(); i++)
{
String p = jar.getString(i);
Log.i("p",p);
}
} catch (JSONException e) {
e.printStackTrace();
}
我想从服务器的JSON数据接收创建JSON对象作为字符串.
我从服务器收到以下JSON数据到字符串"practiceInfoByUsername"
