来自android的url的Json响应 [英] Json response from url in android

问题描述

i从数据服务获得响应后，从字符串创建JSON数组显示异常，这是我的代码



response = client.execute（request）;

// getJSONString（response）;

entity = response.getEntity（）;

int length =（int）entity.getContentLength（）;

StringBuffer sb = new StringBuffer（length）;

if（entity.getContentLength（）！= 0）{

reader = new InputStreamReader（entity.getContent（），UTF-8）;



String line =;



BufferedReader bufferedReader = new BufferedReader（reader）;

while（（line = bufferedReader.readLine（））！= null）

结果+ =行;

reader.close（）;



jar = new JSONArray（result）;

for（int i = 0; i< jar.length（）; i ++）{



try {

JSONObject c = jar.getJSONObject（i）;

String vtype = c.getString（ChannelID）;

res.setText（+ vtype）;

}

catch（JSONException e）{

e.printStackTrace（）;

}

}



}

大胆的声明我得到了例外。需要帮助来解决这个问题

推荐答案

结果是一个JSONObject，它可能包含string，int，JSONArray。

The result is a JSONObject which may contain string, int, JSONArray.

jar = new JSONArray(result);

应该是

should be

JSONObject jar  = new JSONObject(result);
