我尝试过使用twitter4j让用户在twitter上发帖，但遗憾的是我不断收到401错误。我已经三次检查了我的凭据，并要求提供新密钥，但这没有结果。这是我的代码：
public class LoginFragment extends Fragment {
ImageView login;
Twitter twitter;
RequestToken requestToken = null;
AccessToken accessToken;
String oauth_url,oauth_verifier,profile_url;
Dialog auth_dialog;
WebView web;
SharedPreferences pref;
ProgressDialog progress;
Bitmap bitmap;
String TAG = LoginFragment.class.getSimpleName();
@Override
public View onCreateView(LayoutInflater inflater,ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.login_fragment, container, false);
login = (ImageView)view.findViewById(R.id.login);
pref = getActivity().getPreferences(0);
ConfigurationBuilder builder = new ConfigurationBuilder();
builder.setDebugEnabled(true);
builder.setOAuthConsumerKey(pref.getString("CONSUMER_KEY", ""));
builder.setOAuthConsumerSecret(pref.getString("CONSUMER_SECRET",""));
builder.setOAuthAccessToken(null);
builder.setOAuthAccessTokenSecret(null);
TwitterFactory factory = new TwitterFactory(builder.build());
twitter = factory.getInstance();
// twitter = new TwitterFactory().getInstance();
// Toast.makeText(getActivity(),"Key is " + pref.getString("CONSUMER_KEY","") + "Secret is " + pref.getString("CONSUMER_SECRET",""),Toast.LENGTH_LONG).show();
// twitter.setOAuthConsumer(pref.getString("CONSUMER_KEY", ""), pref.getString("CONSUMER_SECRET", ""));
login.setOnClickListener(new LoginProcess());
return view;
}
private class LoginProcess implements OnClickListener {
@Override
public void onClick(View v) {
Toast.makeText(getActivity(),"Pressed",Toast.LENGTH_LONG).show();
// TODO Auto-generated method stub
new TokenGet().execute();
}}

// Log.d(TAG, "Sheldon the RequestToken is " + requestToken);
// oauth_url = requestToken.getAuthorizationURL();
requestToken = twitter.getOAuthRequestToken("http://tweetie.com");
Log.d(TAG, "Sheldon the RequestToken is " + requestToken);
oauth_url = requestToken.getAuthorizationURL();
//End
} catch (TwitterException e) {

}
Log.d(TAG,"Sheldon the OAUTH URL is " + oauth_url);

auth_dialog.dismiss();
new AccessTokenGet().execute();
}else if(url.contains("denied")){

}
});
auth_dialog.show();

答案 0 :(得分：0)
在Twitter设置开发帐户中填写“回拨网址”字段和“组织网址”。 但是不要启用回调锁定， 这对我来说就像一块宝石！
