Android 如何在朋友'；安卓的Facebook墙

我制作了一个应用程序，其中我制作了一个EditText和一个按钮。我想在点击按钮后在Facebook好友墙上的EditText上发布这条消息。请告诉我如何使用Facebook sdk执行此任务

代码如下：

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        this.setContentView(R.layout.post_wall);

        share = (Button) findViewById(R.id.share);
        friend_name = (TextView) findViewById(R.id.wall_to);
        wall = (EditText) findViewById(R.id.wall);

        savedInstanceState = new Bundle();
        savedInstanceState.getString("to");

        onComplete(savedInstanceState);

    }

@Override public void onComplete(Bundle values)
    {

        Utility.currentPermissions.clear();


        if (values.isEmpty())
        {
            //"skip" clicked ?
            return;
        }

        // if facebookClient.authorize(...) was successful, this runs
        // this also runs after successful post
        // after posting, "to"(which is the id of friend) is added to the values bundle
        // I use that to differentiate between a call from
        // faceBook.authorize(...) and a call from a successful post
        // is there a better way of doing this?
        if (!values.containsKey("to"))
        {
            try
            {
                Log.d("Wall try", "Click successfully");

                for (String key : parameters.keySet()) {
                    if (parameters.getByteArray(key) != null) {
                        parameters.putByteArray(key, parameters.getByteArray(key));

                        Log.d("key", parameters.getByteArray(key).toString());
                    }
                }

                mHandler.post(new Runnable() {
                    @Override
                    public void run() {
                        performActivityInfo();
                    }
                });


            }
            catch (Exception e)
            {
                // TODO: handle exception
                System.out.println(e.getMessage());
            }
        }
    }



protected void performActivityInfo() {

        Log.d("perform wall", "Perform Activity");
        mHandler.sendEmptyMessage(FRIEND_WALL);


        parameters.putString("message", wall.getText().toString());
        facebookClient.dialog(this, "stream.publish", parameters, this);// "stream.publish" is an API call
        Log.d("Wall post", "Click successfully");

    }

    public Handler mHandler = new Handler() {
        @Override
        public void handleMessage(Message msg) {
            switch (msg.what) {
            case FRIEND_WALL:
                Log.d("Handler WALL", "Handler");
                postOnWall(wall.getText().toString());
                break;
            }
            super.handleMessage(msg);
        }
    };



 @Override
    public void onError(DialogError e)
    {
        System.out.println("Error: " + e.getMessage());
    }

    @Override
    public void onFacebookError(FacebookError e)
    {
        System.out.println("Error: " + e.getMessage());
    }

    @Override
    public void onCancel()
    {
    }

    @Override
    public void onClick(View v)
    {
            facebookClient = new Facebook(APP_ID);
            // replace APP_API_ID with your own
            Log.d("Wall click", "Click successfully");
            facebookClient.authorize(this,
                new String[] {"publish_stream", "read_stream", "offline_access"}, this);
    }

    public void postOnWall(String msg) {
        Log.d("Tests", "Testing graph API wall post");
         try {
                String response = facebookClient.request("me");
                Bundle parameters = new Bundle();
                parameters.putString("message", msg);
                parameters.putString("description", "test test test");
                response = facebookClient.request("me/feed", parameters, 
                        "POST");
                Log.d("Tests", "got response: " + response);
                if (response == null || response.equals("") || 
                        response.equals("false")) {
                   Log.v("Error", "Blank response");
                }
         } catch(Exception e) {
             e.printStackTrace();
         }
    }

提前感谢。

要从编辑文本中获取值，只需使用：

编辑文本编辑文本

edittext.getEditableText().toString();

里面的按钮点击监听器，然后使用这个代码

button.setOnClickListener(new OnClickListener(){

        @Override
        public void onClick(View arg0) {
            String entered_value=edittext.getEditableText().toString();
            try{
                parameters.putString("message", entered_value);
                parameters.putString("target_id", "XXXXX"); // target Id in which you need to Post 
                parameters.putString("method", "stream.publish");
                String  response = authenticatedFacebook.request(parameters);       
                Log.v("response", response);
            }
            catch(Exception e){}
        }
    });

其中按钮是您的按钮对象。

如果您在该代码中遇到任何问题，请提供一些示例代码。我需要这个密码。
