2.java
(1)OAuth01Activity.java

 package org.marsdroid.oauth01;
 
 import android.app.Activity;
 import android.content.Intent;
 import android.os.Bundle;
 
 public class OAuth01Activity extends Activity {
 
     /** Called when the activity is first created. */
     @Override
     public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.main);
         startActivity(new Intent(this,PrepareRequestTokenActivity.class));
     }
 
 }

(2)Constants.java

 package org.marsdroid.oauth01;
 
 public class Constants {
 
     public static final String CONSUMER_KEY     = "99e9494ff07e42489f4ace16b63e1f47";
     public static final String CONSUMER_SECRET     = "154f6f9ab4c1cf527f8ad8ab1f8e1ec9";
 
     public static final String REQUEST_URL         = "https://open.t.qq.com/cgi-bin/request_token";
     public static final String ACCESS_URL         = "https://open.t.qq.com/cgi-bin/access_token";

     public static final String ENCODING         = "UTF-8";
 
 }

(3)PrepareRequestTokenActivity.java

 package org.marsdroid.oauth01;
 
 import oauth.signpost.OAuthConsumer;
 import oauth.signpost.OAuthProvider;
 import oauth.signpost.commonshttp.CommonsHttpOAuthConsumer;
 import oauth.signpost.commonshttp.CommonsHttpOAuthProvider;
 import android.app.Activity;
 import android.os.Bundle;
 
 public class PrepareRequestTokenActivity extends Activity {
 
     private OAuthConsumer consumer;
     private OAuthProvider provider;
     @Override
     protected void onCreate(Bundle savedInstanceState) {
         // TODO Auto-generated method stub
         super.onCreate(savedInstanceState);
 
         consumer = new CommonsHttpOAuthConsumer(Constants.CONSUMER_KEY, Constants.CONSUMER_SECRET);
         provider = new CommonsHttpOAuthProvider(Constants.REQUEST_URL, Constants.ACCESS_URL, Constants.AUTHORIZE_URL);
 
         new OAuthRequestTokenTask(this, consumer, provider).execute();
     }
 
 }

(4)OAuthRequestTokenTask.java

用异步任务

 package org.marsdroid.oauth01;
 
 import oauth.signpost.OAuthConsumer;
 import oauth.signpost.OAuthProvider;
 import android.content.Context;
 import android.os.AsyncTask;
 
 public class OAuthRequestTokenTask extends AsyncTask<Void, Void, Void>{
 
     private Context context;
     private OAuthConsumer consumer;
     private OAuthProvider provider;
 
     public OAuthRequestTokenTask(Context context, OAuthConsumer consumer,
             OAuthProvider provider) {
         super();
         this.context = context;
         this.consumer = consumer;
         this.provider = provider;
     }
 
     @Override
     protected Void doInBackground(Void... params) {
         // TODO Auto-generated method stub
         try {
             System.out.println("请求Request Token之前" + consumer.getToken());
             //用户授权要用此url
             final String url = provider.retrieveRequestToken(consumer, "null");
             System.out.println("请求Request Toker之后" + consumer.getToken());
             System.out.println("url---->" + url);
         } catch(Exception e) {
             // TODO Auto-generated catch block
             e.printStackTrace();
         }
         return null;
     }
 
 }
