我在我的应用程序中使用了一个共享按钮，它使用 twitter 如下：
public class TwitterApp {
private Twitter mTwitter;
private TwitterSession mSession;
private AccessToken mAccessToken;
private CommonsHttpOAuthConsumer mHttpOauthConsumer;
private OAuthProvider mHttpOauthprovider;
private String mConsumerKey;
private String mSecretKey;
private ProgressDialog mProgressDlg;
private TwDialogListener mListener;
private Context context;
public static final String CALLBACK_URL = "http://www.rommanapps.com";
private static final String TAG = "TwitterApp";
public TwitterApp(Context context, String consumerKey, String secretKey) {
this.context = context;
mTwitter = new TwitterFactory().getInstance();
mSession = new TwitterSession(context);
mProgressDlg = new ProgressDialog(context);
mProgressDlg.requestWindowFeature(Window.FEATURE_NO_TITLE);
mConsumerKey = consumerKey;
mSecretKey = secretKey;
mTwitter.setOAuthConsumer(consumerKey, secretKey);
mHttpOauthConsumer = new CommonsHttpOAuthConsumer(mConsumerKey, mSecretKey);
mHttpOauthprovider = new DefaultOAuthProvider("https://api.twitter.com/oauth/request_token",
"https://api.twitter.com/oauth/access_token",
"https://api.twitter.com/oauth/authorize");
mAccessToken = mSession.getAccessToken();
configureToken();
}
public void setListener(TwDialogListener listener) {
mListener = listener;
}
@SuppressWarnings("deprecation")
private void configureToken() {
if (mAccessToken != null) {
mTwitter.setOAuthConsumer(mConsumerKey, mSecretKey);
mTwitter.setOAuthAccessToken(mAccessToken);
}
}
public boolean hasAccessToken() {
return (mAccessToken == null) ? false : true;
}
public void resetAccessToken() {
if (mAccessToken != null) {
mSession.resetAccessToken();
mAccessToken = null;
}
}
public String getUsername() {
return mSession.getUsername();
}
public void updateStatus(String status) throws Exception {
try {
mTwitter.updateStatus(status);
} catch (TwitterException e) {
throw e;
}
}
public void authorize() {
mProgressDlg.setMessage("Initializing ...");
mProgressDlg.show();
new Thread() {
@Override
public void run() {
String authUrl = "";
int what = 1;
try {
authUrl = mHttpOauthprovider.retrieveRequestToken(mHttpOauthConsumer, CALLBACK_URL);
what = 0;
Log.d(TAG, "Request token url " + authUrl);
} catch (Exception e) {
Log.d(TAG, "Failed to get request token");
e.printStackTrace();
}
mHandler.sendMessage(mHandler.obtainMessage(what, 1, 0, authUrl));
}
}.start();
}
public void processToken(String callbackUrl) {
mProgressDlg.setMessage("Finalizing ...");
mProgressDlg.show();
final String verifier = getVerifier(callbackUrl);
new Thread() {
@Override
public void run() {
int what = 1;
try {
mHttpOauthprovider.retrieveAccessToken(mHttpOauthConsumer, verifier);
mAccessToken = new AccessToken(mHttpOauthConsumer.getToken(), mHttpOauthConsumer.getTokenSecret());
configureToken();
User user = mTwitter.verifyCredentials();
mSession.storeAccessToken(mAccessToken, user.getName());
what = 0;
} catch (Exception e){
Log.d(TAG, "Error getting access token");
e.printStackTrace();
}
mHandler.sendMessage(mHandler.obtainMessage(what, 2, 0));
}
}.start();
}
private String getVerifier(String callbackUrl) {
String verifier = "";
try {
callbackUrl = callbackUrl.replace("twitterapp", "http");
URL url = new URL(callbackUrl);
String query = url.getQuery();
String array[] = query.split("&");
for (String parameter : array) {
String v[] = parameter.split("=");
if (URLDecoder.decode(v[0]).equals(oauth.signpost.OAuth.OAUTH_VERIFIER)) {
verifier = URLDecoder.decode(v[1]);
break;
}
}
} catch (MalformedURLException e) {
e.printStackTrace();
}
return verifier;
}
private void showLoginDialog(String url) {
final TwDialogListener listener = new TwDialogListener() {
@Override
public void onComplete(String value) {
processToken(value);
}
@Override
public void onError(String value) {
mListener.onError("Failed opening authorization page");
}
};
new TwitterDialog(context, url, listener).show();
}
private Handler mHandler = new Handler() {
@Override
public void handleMessage(Message msg) {
mProgressDlg.dismiss();
if (msg.what == 1) {
if (msg.arg1 == 1)
mListener.onError("Error getting request token");
else
mListener.onError("Error getting access token");
} else {
if (msg.arg1 == 1)
showLoginDialog((String) msg.obj);
else
mListener.onComplete("");
}
}
};
public interface TwDialogListener {
public void onComplete(String value);
public void onError(String value);
}
}
我对这个陈述有误
mHttpOauthprovider = new DefaultOAuthProvider("https://api.twitter.com/oauth/request_token", "https://api.twitter.com/oauth/access_token", "https://api.twitter.com/oauth/授权”）;
它说构造函数 DefaultOAuthProvider(String, String, String) 未定义
mAccessToken = mSession.getAccessToken();
上面写着Type mismatch: cannot convert from twitter4j.auth.AccessToken to twitter4j.http.AccessToken
而且我不知道问题出在哪里！请帮忙
