新浪微博API如何获取uid，并根据uid获取用户的基本信息，如粉丝，关注等，

下面是根据sdk写的，但是获取不到

public String showUser(Context context, String id)

throws MalformedURLException, IOException, WeiboException {

String rlt = "";

try {

Weibo mWeibo = Weibo.getInstance();

String url = Weibo.SERVER + "users/show.json";

Log.i("Weibo", "Weibo.showUser().url " + url);

WeiboParameters bundle = new WeiboParameters();

bundle.add("source", Weibo.getAppKey());

bundle.add("access_token", mWeibo.getAccessToken().getToken());

//            bundle.add("access_token", Weibo.getInstance().getAccessToken()

//                    .getToken());

bundle.add("uid", id);

rlt = mWeibo.request(context, url, bundle, "GET",

mWeibo.getAccessToken());

Log.i("Weibo", "Weibo.showUser().rlt " + rlt);

} catch (Exception e) {

e.printStackTrace();

}
