我想在Linkedin上分享我使用下面代码的文字

    public class ShareWithLinkedIn extends Activity {
public static final String CONSUMER_KEY = "YOUR_COUSUMER_KEY";
public static final String CONSUMER_SECRET = "YOUR_SECRET_KEY";

final LinkedInOAuthService oAuthService = LinkedInOAuthServiceFactory.getInstance().createLinkedInOAuthService(CONSUMER_KEY, CONSUMER_SECRET);
final LinkedInApiClientFactory factory = LinkedInApiClientFactory.newInstance(CONSUMER_KEY, CONSUMER_SECRET);

LinkedInApiClient client;

}// end method

@Override
protected void onNewIntent(Intent intent) {
    finishAuthenticate(intent.getData());
}// end method

} //结束课

它显示我登录和允许屏幕，当我再次单击该按钮时，将显示相同的屏幕，但我想要的时候（我点击该按钮它应该与图像网址共享文本）...

任何人都可以帮我解决这个问题

通过以下代码我已经完成了

    public class ShareInLinkedIn extends Activity implements OnClickListener {

private LinkedInOAuthService oAuthService;
private LinkedInApiClientFactory factory;
private LinkedInRequestToken liToken;
private LinkedInApiClient client;
public static final String LINKEDIN_PREF = "GamePrefs";

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.linkedin);

    if (android.os.Build.VERSION.SDK_INT > 9) {
        StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
        StrictMode.setThreadPolicy(policy);
    }

    oAuthService = LinkedInOAuthServiceFactory.getInstance().createLinkedInOAuthService(Constants.CONSUMER_KEY, Constants.CONSUMER_SECRET, Constants.SCOPE_PARAMS);
    System.out.println("oAuthService : " + oAuthService);

    factory = LinkedInApiClientFactory.newInstance(Constants.CONSUMER_KEY, Constants.CONSUMER_SECRET);

    liToken = oAuthService.getOAuthRequestToken(Constants.OAUTH_CALLBACK_URL);
    System.out.println("onCreate:linktoURL : " + liToken.getAuthorizationUrl());
    Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse(liToken.getAuthorizationUrl()));
    startActivity(i);

    client = factory.createLinkedInApiClient(accessToken);

    // client.postNetworkUpdate("LinkedIn Android app test");

    Person profile = client.getProfileForCurrentUser(EnumSet.of(ProfileField.ID, ProfileField.FIRST_NAME, ProfileField.LAST_NAME, ProfileField.HEADLINE));

    System.out.println("First Name :: " + profile.getFirstName());

    OAuthConsumer consumer = new CommonsHttpOAuthConsumer(Constants.CONSUMER_KEY, Constants.CONSUMER_SECRET);
    consumer.setTokenWithSecret(accessToken.getToken(), accessToken.getTokenSecret());

    DefaultHttpClient httpclient = new DefaultHttpClient();

        StringBuffer strBfr = new StringBuffer();   
        String line = "";

    } catch (Exception e) {

}

@Override

}

}
