求android获取网页数据

Question

假设http：//10.10.10.10/test.php的代码是<?php
echo "helloworld"
?>怎样用android代码获取这个字符串？初学，请提供代码。。

Answer 1

晕死，太简单，已经自己解决了，问题改成怎么解析以下字符串到android程序接收{"fjxname":"p1","j":"113.591019","w":"24.810411"}
{"fjxname":"p2","j":"114.591019","w":"24.810411"}
{"fjxname":"p3","j":"115.591019","w":"24.810411"}
{"fjxname":"p4","j":"116.591019","w":"24.810411"}

Answer 2

这不就是json数据么，用JsonObject android自带的啊

Answer 3

我直接写个给你看看：
String resData="你返回的JSON字符串";
JSONOArray jarry = new JSONOArray(resData);
for(int i=0;i<jarry.length;i++){
   System.out.println(jarry.getJSONObject(i).getString("fjxname"));
}你的数据格式有问题，应该这样的才对：
[{"fjxname":"p1","j":"113.591019","w":"24.810411"},
{"fjxname":"p2","j":"114.591019","w":"24.810411"},
{"fjxname":"p3","j":"115.591019","w":"24.810411"},
{"fjxname":"p4","j":"116.591019","w":"24.810411"}]

Answer 4

不知我这代码哪里错了            String strResult = EntityUtils.toString(httpResponse.getEntity()); 
            JSONArray jarry = new JSONArray(strResult);
            for(int i=0;i<jarry.length();i++){
gjx1 = jarry.getJSONObject(i).getString("gjxname");
j1 = jarry.getJSONObject(i).getString("j");
w1 = jarry.getJSONObject(i).getString("w");
              //System.out.println(jarry.getJSONObject(i).getString("fjxname"));
            }运行时老是程序出错，工具里却没提示错误

Answer 6

你是不是数据格式不正确呀
应该这样的才对：
[{"fjxname":"p1","j":"113.591019","w":"24.810411"},
{"fjxname":"p2","j":"114.591019","w":"24.810411"},
{"fjxname":"p3","j":"115.591019","w":"24.810411"},
{"fjxname":"p4","j":"116.591019","w":"24.810411"}]

Answer 7

数据格式我已经改成
[{"fjxname":"p1","j":"113.591019","w":"24.810411"},
{"fjxname":"p2","j":"114.591019","w":"24.810411"},
{"fjxname":"p3","j":"115.591019","w":"24.810411"},
{"fjxname":"p4","j":"116.591019","w":"24.810411"}]了
返回空值。。所以程序出错，eclipse没有提示错误的。。

Answer 8

这是我test.php上的代码[{"fjxname":"p1","j":"113.591019","w":"24.810411"},
{"fjxname":"p2","j":"114.591019","w":"24.810411"},
{"fjxname":"p3","j":"115.591019","w":"24.810411"},
{"fjxname":"p4","j":"116.591019","w":"24.810411"}]

Answer 9

问题解决了，那就散分吧
你可以先学习一下JSON的格式
