android 怎么接受网址上的json数组，并解析

求个源码

Answer 1

传入网址路径，获取字符串
public static String getHtmlContent(String url) {
String htmlCode = null;
StringBuffer resultBuffer = new StringBuffer();

HttpGet request = new HttpGet(url);
HttpClient httpClient = new DefaultHttpClient();
try {
HttpResponse response = httpClient.execute(request);
if(response.getStatusLine().getStatusCode() == 200)
{
HttpEntity entity = response.getEntity();
BufferedReader io = new BufferedReader(new InputStreamReader(entity.getContent(),"UTF-8"));
String strResult;
while((strResult = io.readLine())!=null){
resultBuffer.append(strResult);
}
htmlCode = new String(resultBuffer);
io.close();
}
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return htmlCode;
}
解析json字符串
private String parseJson(String strResult) {
String temp = null;
try {
JSONObject jsonObj = new JSONObject(strResult).getJSONObject("weatherinfo");
temp = jsonObj.getInt("temp") + "#" +jsonObj.getString("city");
} catch (JSONException e) {
System.out.println("Json parse error");
e.printStackTrace();
}
return temp;
}
注意事项：网络请求要异步操作
