我想不使用twitter4j而使用Twitter Rest Api。面料很好，但是我找不到像getingUserFollowers()这样的方法。我不知道为什么会这样。无论如何，我想使用此服务给我的用户关注者ID。 https://dev.twitter.com/rest/reference/get/followers/ids
我看过面料网站(http://docs.fabric.io/android/twitter/access-rest-api.html#tweets)的教程。有一个用于获取定制服务的类。但是我不明白我怎么称呼它的发送参数。
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);
}
}
我认为当我发送ID时，服务会带来关注者ID。
MyTwitterApiClient aa = new MyTwitterApiClient(session);
aa.getCustomService().show(userId);
但是应用已停止。我怎么了？
LogCat是

最佳答案
实际上，Fabric使用改造来进行REST Api调用，如上所述
在Fabric文档中，为了获取关注者的ID，我们需要传递
user_id作为参数，并作为响应检索列表。
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<Response> cb);
}
现在在MainActivity中，我们将对用户进行身份验证，然后通过
在会话中，我们将检索所有对应的关注者列表
一个用户ID。
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<TwitterSession>() {
@Override
public void success(Result<TwitterSession> 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()

Twitter.getApiClient(session).getAccountService()
.verifyCredentials(true, false, new Callback<User>() {
@Override
public void success(Result<User> 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);

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<ids.length();i++){
System.out.println("Id of user "+(i+1)+" is "+ids.get(i));
}
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
}
@Override
public void failure(TwitterException exception) {
// Do something on failure
}
});
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
// Pass the activity result to the login button.
loginButton.onActivityResult(requestCode, resultCode, data);
}
