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 AUTHORIZE_URL     = "https://open.t.qq.com/cgi-bin/authorize";
    
    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;
    }

}
