如何使用Twitter 4j检索Twitter用户的名字

Question

我是android开发的新手(和java一般).我正在构建一个应用程序,要求用户通过登录到他们的基本信息导入和保存的Twitter帐户进行注册.所需的信息将是生日,姓名(全名),用户名,位置,性别等.我正在使用twitter4j来完成此任务.我试过看twitter4j文档,但是作为一个Android新手(和一般的java),文档有点难以理解,所以我似乎无法让它做除了设置状态更新之外的事情.

这是我活动中的代码:

package cc.co.localsquare.app;

import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.widget.Toast;
import oauth.signpost.OAuthProvider;
import oauth.signpost.basic.DefaultOAuthProvider;
import oauth.signpost.commonshttp.CommonsHttpOAuthConsumer;
import oauth.signpost.exception.OAuthCommunicationException;
import oauth.signpost.exception.OAuthExpectationFailedException;
import oauth.signpost.exception.OAuthMessageSignerException;
import oauth.signpost.exception.OAuthNotAuthorizedException;
import twitter4j.Twitter;
import twitter4j.TwitterFactory;
import twitter4j.http.AccessToken;

public class ConnectTwitterActivity extends BaseActivity {

  public final static String CONSUMER_KEY = "valid key";
  public final static String CONSUMER_SECRET = "valid secret";
  public final static String CALLBACK_URL = "localsquare://ConnectTwitterActivity2";

  private CommonsHttpOAuthConsumer commonHttpOAuthConsumer;
  private OAuthProvider authProvider;

  private Twitter twitter;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.connect_twitter);

        commonHttpOAuthConsumer = new CommonsHttpOAuthConsumer(CONSUMER_KEY, CONSUMER_SECRET);
        authProvider = new DefaultOAuthProvider("http://twitter.com/oauth/request_token",
            "http://twitter.com/oauth/access_token", "http://twitter.com/oauth/authorize");
        try {
      String oAuthURL = authProvider.retrieveRequestToken(commonHttpOAuthConsumer, CALLBACK_URL);
      this.startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(oAuthURL)));
    } catch (OAuthMessageSignerException e) {
      Toast.makeText(this, e.getMessage(), Toast.LENGTH_LONG).show();
      e.printStackTrace();
    } catch (OAuthNotAuthorizedException e) {
      Toast.makeText(this, e.getMessage(), Toast.LENGTH_LONG).show();
      e.printStackTrace();
    } catch (OAuthExpectationFailedException e) {
      Toast.makeText(this, e.getMessage(), Toast.LENGTH_LONG).show();
      e.printStackTrace();
    } catch (OAuthCommunicationException e) {
      Toast.makeText(this, e.getMessage(), Toast.LENGTH_LONG).show();
      e.printStackTrace();
    }
    }

    protected void onNewIntent(Intent intent) {
      super.onNewIntent(intent);

      Uri uri = intent.getData();
      if (uri != null && uri.toString().startsWith(CALLBACK_URL)) {
        String verifier = uri.getQueryParameter(oauth.signpost.OAuth.OAUTH_VERIFIER);
        try {
          authProvider.retrieveAccessToken(commonHttpOAuthConsumer, verifier);

          AccessToken accessToken = new AccessToken(commonHttpOAuthConsumer.getToken(),
              commonHttpOAuthConsumer.getTokenSecret());

          twitter = new TwitterFactory().getInstance();
          twitter.setOAuthConsumer(CONSUMER_KEY, CONSUMER_SECRET);

          twitter.setOAuthAccessToken(accessToken);

          // Alternate way:
          // twitter = new TwitterFactory().getOAuthAuthorizedInstance(CONSUMER_KEY, CONSUMER_SECRET,
          //     new AccessToken(commonHttpOAuthConsumer.getToken(), commonHttpOAuthConsumer.getTokenSecret()));

          // Tweet message to be updated.
          String tweet = "Hi there, This was sent from my application - OAuth, Twitter";
          twitter.updateStatus(tweet);

        }
        catch (Exception e) {
          Toast.makeText(getBaseContext(), e.getMessage(), Toast.LENGTH_LONG);
        }
      }
    }

}

我怎样才能解决我的问题？

如果你有一个人,你需要获得细节的Twitter用户的网名,那么你可以使用User user = twitter.showUser(screenName);.现在您可以通过使用对象getter函数访问有关用户的信息user,例如user.getName(),user.getLocation()等等.

记得User在Eclipse中导入该类.通常,您也可以在Eclipse中按Ctrl+ Shift+ O来完成.
