Question

我在我的应用上有这个方法：

@SuppressWarnings("deprecation")
void displayTimeLine(String token, String secret) {
    if (null != token && null != secret) {
        List<Status> statuses = null;
        try {
            twitter.setOAuthAccessToken(token, secret);
            statuses = twitter.getUserTimeline();
            Toast.makeText(this, statuses.get(0).getText(), Toast.LENGTH_LONG)
                .show();
        } catch (Exception ex) {
            Toast.makeText(this, "Error:" + ex.getMessage(),
                    Toast.LENGTH_LONG).show();
            Log.d("Main.displayTimeline",""+ex.getMessage());
        }

    } else {
        Toast.makeText(this, "Not Verified", Toast.LENGTH_LONG).show();
    }
}

它抛出了这个错误：

Error:(106, 12) error: method setOAuthAccessToken in interface   OAuthSupport cannot be applied to given types;
required: AccessToken
found: String,String
reason: actual and formal argument lists differ in length

我正在导入基于eclipse的项目（旧的twitter4j示例），我不得不更改这些导入：

import twitter4j.http.AccessToken;
import twitter4j.http.RequestToken;

要：

import twitter4j.auth.AccessToken;
import twitter4j.auth.RequestToken;

这是完整的课程：

您可能希望尝试使用更新的库（我不确定您的版本）。

注意：在公共站点中发布时，应始终删除您的消费者和消费者密钥。（：

在on onCreate方法上，添加

    twitter = new TwitterFactory().getInstance();

    twitter.setOAuthConsumer("Consumer Key", "Consumer Secret");

要调用我的tokenGet类，

  new TokenGet().execute();

以及tokenGet方法

    private class TokenGet extends AsyncTask<String, String, String> {

    @Override
    protected String doInBackground(String... args) {

        try {
            requestToken = twitter.getOAuthRequestToken();
            oauth_url = requestToken.getAuthorizationURL();
        } catch (TwitterException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        return oauth_url;
    }
    @Override
    protected void onPostExecute(String oauth_url) {
        if(oauth_url != null){
            Log.e("URL", oauth_url);
            auth_dialog = new Dialog(getActivity());
            auth_dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);

            auth_dialog.setContentView(R.layout.auth_dialog);
            web = (WebView)auth_dialog.findViewById(R.id.webv);
            web.getSettings().setJavaScriptEnabled(true);
            web.loadUrl(oauth_url);
            web.setWebViewClient(new WebViewClient() {
                boolean authComplete = false;
                @Override
                public void onPageStarted(WebView view, String url, Bitmap favicon){
                    super.onPageStarted(view, url, favicon);
                }

                @Override
                public void onPageFinished(WebView view, String url) {
                    super.onPageFinished(view, url);
                    if (url.contains("oauth_verifier") && authComplete == false){
                        authComplete = true;
                        Log.e("Url",url);
                        Uri uri = Uri.parse(url);
                        oauth_verifier = uri.getQueryParameter("oauth_verifier");

                        auth_dialog.dismiss();
                        new AccessTokenGet().execute();
                    }else if(url.contains("denied")){
                        auth_dialog.dismiss();
                        Toast.makeText(getActivity(), "Sorry !, Permission Denied", Toast.LENGTH_SHORT).show();


                    }
                }
            });
            auth_dialog.show();
            auth_dialog.setCancelable(true);



        }else{

            Toast.makeText(getActivity(), "Sorry !, Network Error or Invalid Credentials", Toast.LENGTH_SHORT).show();


        }
    }
}

private class AccessTokenGet extends AsyncTask<String, String, Boolean> {


    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        progress = new ProgressDialog(getActivity());
        progress.setMessage("Fetching Data ...");
        progress.setProgressStyle(ProgressDialog.STYLE_SPINNER);
        progress.setIndeterminate(true);
        progress.show();

    }


    @Override
    protected Boolean doInBackground(String... args) {

        try {


            accessToken = twitter.getOAuthAccessToken(requestToken, oauth_verifier);
            SharedPreferences.Editor edit = pref.edit();
            edit.putString("ACCESS_TOKEN", accessToken.getToken());
            edit.putString("ACCESS_TOKEN_SECRET", accessToken.getTokenSecret());

            edit.commit();


        } catch (TwitterException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();


        }

        return true;
    }
    @Override
    protected void onPostExecute(Boolean response) {
        if(response){
            Intent i = new Intent(getActivity(),MainMenu.class);

在此处获取您的访问令牌

            i.putExtra("ACCESS_TOKEN", accessToken.getToken());
            i.putExtra("ACCESS_TOKEN_SECRET", accessToken.getTokenSecret());
            startActivity(i);
        }
    }


}

我使用的是twitter4j的4.0.3版本。这适用于我的情况。我从一些教程网站上拿了一些东西，但是我现在还记不起网址了。
