如何使用Twitter Fabric Android获取关注者列表？

我想在不使用twitter4j的情况下使用Twitter Rest Api。 Fabric很好但我找不到像gettingUserFollowers（）这样的方法。 我不知道为什么会这样。 无论如何，我想使用此服务呼叫我的用户关注者ID。 https://dev.twitter.com/rest/reference/get/followers/ids

我看过面料网站的教程（ http://docs.fabric.io/android/twitter/access-rest-api.html#tweets ）。 有一个用于获取自定义服务的类。 但我无法理解我如何称之为发送参数。我将其改为如下

import com.twitter.sdk.android.core.TwitterApiClient; import com.twitter.sdk.android.core.TwitterSession; import retrofit.http.GET; import retrofit.http.Query; public class MyTwitterApiClient extends TwitterApiClient { public MyTwitterApiClient(TwitterSession session) { super(session); } public CustomService getCustomService() { return getService(CustomService.class); } interface CustomService { @GET("/1.1/followers/ids.json") void show(@Query("user_id") long id); } } 

我想当我发送身份证时，服务会带来粉丝。

 MyTwitterApiClient aa = new MyTwitterApiClient(session); aa.getCustomService().show(userId); 

但应用程序停止了。我错了什么？

LogCat是

实际上，Fabric使用改进来进行REST Api调用，并且如Fabric文档中所述，为了获取关注者的ID，我们需要将user_id作为参数传递并在响应中检索列表。

MyTwitterApiClient.java

 import com.twitter.sdk.android.core.Callback; import com.twitter.sdk.android.core.TwitterApiClient; import com.twitter.sdk.android.core.TwitterSession; import retrofit.client.Response; import retrofit.http.GET; import retrofit.http.Query; public class MyTwitterApiClient extends TwitterApiClient { public MyTwitterApiClient(TwitterSession session) { super(session); } /** * Provide CustomService with defined endpoints */ public CustomService getCustomService() { return getService(CustomService.class); } } // example users/show service endpoint interface CustomService { @GET("/1.1/followers/ids.json") void list(@Query("user_id") long id, Callback cb); } 

现在，在MainActivity中，我们将对用户进行身份validation，然后通过获取会话，我们将检索与userid相对应的所有关注者的列表。

MainActivity.java

 public class MainActivity extends AppCompatActivity { // Note: Your consumer key and secret should be obfuscated in your source code before shipping. private static final String TWITTER_KEY = "YOUR_TWITTER_KEY"; private static final String TWITTER_SECRET = "YOUR_TWITTER_SECRET"; TwitterLoginButton loginButton; SharedPreferences shared; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); TwitterAuthConfig authConfig = new TwitterAuthConfig(TWITTER_KEY, TWITTER_SECRET); Fabric.with(this, new Twitter(authConfig), new Crashlytics()); setContentView(R.layout.activity_main); shared = getSharedPreferences("demotwitter", Context.MODE_PRIVATE); loginButton = (TwitterLoginButton) findViewById(R.id.login_button); loginButton.setCallback(new Callback() { @Override public void success(Result result) { // Do something with result, which provides a TwitterSession for making API calls TwitterSession session = Twitter.getSessionManager() .getActiveSession(); TwitterAuthToken authToken = session.getAuthToken(); String token = authToken.token; String secret = authToken.secret; //Here we get all the details of user's twitter account System.out.println(result.data.getUserName() + result.data.getUserId()); Twitter.getApiClient(session).getAccountService() .verifyCredentials(true, false, new Callback() { @Override public void success(Result userResult) { User user = userResult.data; //Here we get image url which can be used to set as image wherever required. System.out.println(user.profileImageUrl+" "+user.email+""+user.followersCount); } @Override public void failure(TwitterException e) { } }); shared.edit().putString("tweetToken", token).commit(); shared.edit().putString("tweetSecret", secret).commit(); TwitterAuthClient authClient = new TwitterAuthClient(); authClient.requestEmail(session, new Callback() { @Override public void success(Result result) { // Do something with the result, which provides the // email address System.out.println(result.toString()); Log.d("Result", result.toString()); Toast.makeText(getApplicationContext(), result.data, Toast.LENGTH_LONG).show(); } @Override public void failure(TwitterException exception) { // Do something on failure System.out.println(exception.getMessage()); } }); MyTwitterApiClient apiclients=new MyTwitterApiClient(session); apiclients.getCustomService().list(result.data.getUserId(), new Callback() { @Override public void failure(TwitterException arg0) { // TODO Auto-generated method stub } @Override public void success(Result arg0) { // TODO Auto-generated method stub BufferedReader reader = null; StringBuilder sb = new StringBuilder(); try { reader = new BufferedReader(new InputStreamReader(arg0.response.getBody().in())); String line; try { while ((line = reader.readLine()) != null) { sb.append(line); } } catch (IOException e) { e.printStackTrace(); } } catch (IOException e) { e.printStackTrace(); } String result = sb.toString(); System.out.println("Response is>>>>>>>>>"+result); try { JSONObject obj=new JSONObject(result); JSONArray ids=obj.getJSONArray("ids"); //This is where we get ids of followers for(int i=0;i 

Answer 2

在Retrofit 2.0中，界面 – >

 public interface FollowersService { @GET("/1.1/followers/list.json") Call list(@Query("screen_name") String userId); } 

调用方法 – >

 FollowersService followersService = followersTwitterApiClient.getFollowersService(); Call call = followersService.list(userId); call.enqueue(followerCallback); 

自定义Api客户端 – >

 public class FollowersTwitterApiClient extends TwitterApiClient { public FollowersTwitterApiClient(TwitterSession twitterSession){ super(twitterSession); } public FollowersService getFollowersService(){ return getService(FollowersService.class); } }

您需要对Twitter进行身份validation才能调用API并获得结果。 我没有在这段代码中看到这种情况。 （也许你是在这段代码之外做的？）
