答案 0 :(得分：1)
尝试解析json String，以便从中获取stream_url：
JSONObject json = jParser.getJSONFromUrl(uri.toString());
JSONObject jsonstation_list=json.getJSONObject("station_list");
ArrayList<String> urlarray=new ArrayList<String>();
// get all names from json object
JSONArray jsonarray_names=jsonstation_list.names();
for(int i=0;i<jsonarray_names.length();i++){
// get jsonobjects
JSONObject jsonone=jsonstation_list.getJSONObject(
jsonarray_names.getString(i));
// get streams
JSONObject jsonstreams=jsonone.getJSONObject("streams");
// get stream_url
urlarray.add(jsonstreams.getString("stream_url"));
}
}
