Android Facebook对话

Question

我已将Facebook集成到我的应用中。 但是，它不会在对话框中显示，而是打开全屏。 我想知道是否有人知道如何将此更改为对话框。

FaceBook处理程序类：

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    /*
     * Get existing access_token if any
     */      
    mPrefs = getPreferences(MODE_PRIVATE);
    String access_token = mPrefs.getString("access_token", null);
    long expires = mPrefs.getLong("access_expires", 0);

    if(access_token != null) 
        facebook.setAccessToken(access_token);

    if(expires != 0) 
        facebook.setAccessExpires(expires);


    if (facebook.isSessionValid()) 
      postFacebookMessage();

    else {
      facebook.authorize(this, new String[] {"publish_stream"}, new Facebook.DialogListener() {

        @Override
        public void onFacebookError(FacebookError e) {
            Toast.makeText(FacebookConnector.this, "Facebook error: " + e.getLocalizedMessage(), Toast.LENGTH_LONG).show();
        }

        @Override
        public void onError(DialogError e) {
            Toast.makeText(FacebookConnector.this, "Facebook dialog error: " + e.getLocalizedMessage(), Toast.LENGTH_LONG).show();
        }

            @Override
        public void onComplete(Bundle values) {
                postFacebookMessage();
            Toast.makeText(FacebookConnector.this, "Thank You For Sharing!", Toast.LENGTH_SHORT).show(); }

        @Override
        public void onCancel() {Toast.makeText(FacebookConnector.this, "Facebook authorization cancelled.", Toast.LENGTH_LONG).show();
        }
    });
    }
} 

private void postFacebookMessage() {

  AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(facebook);
  Bundle params = new Bundle();
  params.putString("message", MSG);
  params.putString("picture", "http://meanwhileinwv.com/meanwhile.png");
  mAsyncRunner.request("me/feed", params, "POST", new FacebookPostListener(), null); }    

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    facebook.authorizeCallback(requestCode, resultCode, data);
}
}

上面的代码产生以下结果：

我希望它是facebook窗口打开的对话框。 我用我的Twitter代码实现了这个目标：

使用附加参数Facebook.FORCE_DIALOG_AUTH调用授权，如下所示：

facebook.authorize(this, new String[] {"publish_stream"}, Facebook.FORCE_DIALOG_AUTH, new Facebook.DialogListener() { ... });
