我已经解析了从 web 服务获得的数据，当我单击需要在 facebook 上共享该项目内容的详细活动页面所需的任何列表项时，它会显示在列表视图中。我尝试使用以下代码，但无法在 facebook 墙上共享数据。有人可以帮我解决这个问题吗？答案将被应用

详细活动

public class Singlemenuitem  extends Activity {
// Your Facebook APP ID
    private static String APP_ID = "308180782571605"; // Replace with your App ID

    // Instance of Facebook Class
    private Facebook facebook = new Facebook(APP_ID);
    private AsyncFacebookRunner mAsyncRunner;
    String FILENAME = "AndroidSSO_data";
    private SharedPreferences mPrefs;


static  String TAG_URL  = "url";






    public String description,title;

// JSON node keys
static final String TAG_TITLE = "title";
static final String TAG_DATE = "date";
static final String TAG_NAME = "name";
static final String TAG_CONTENT = "content";

LinearLayout line1,line2,line3;
   Button btnShare;
   Button btnInvite;


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


 // getting intent data
    Intent in = getIntent();
    final  String url1 = in.getStringExtra(TAG_URL);

    ImageView imgv = (ImageView) findViewById(R.id.imgdesc);
    ImageLoader imageLoader = new  ImageLoader(getApplicationContext());
    imageLoader.DisplayImage(url1, imgv);





   // Get JSON values from previous intent
    final String title = in.getStringExtra(TAG_TITLE);
    String date = in.getStringExtra(TAG_DATE);
    String name = in.getStringExtra(TAG_NAME);
    final String content = in.getStringExtra(TAG_CONTENT);
    System.out.println("bool " +title +" "+date+" "+name +" " +content);
    // Displaying all values on the screen
    TextView lblName = (TextView) findViewById(R.id.name_label);
    TextView lblCost = (TextView) findViewById(R.id.email_label);
    TextView lblDesc = (TextView) findViewById(R.id.mobile_label);
    TextView lblCont = (TextView) findViewById(R.id.content_label);

    lblName.setText(title);
    lblCost.setText(date);
    lblDesc.setText(name);
    lblCont.setText(content);




        //share

    ImageView facebook11=(ImageView) findViewById(R.id.facebook);
    facebook11.setOnClickListener(new View.OnClickListener() {

        //@Override
        public void onClick(View v) {

            Log.d("Image Button", "button Clicked");
            loginToFacebook();

            if (facebook.isSessionValid()) {

              }
        }       

    });


}           







public void loginToFacebook() {

    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);

我已经用Facebook Sdk 3.0
完成了这件事提取该 jar 文件，然后你会找到不同 facebook 功能的示例代码，你只需要输入你的facebook App id。

我在登录时遇到错误，所以我在保存 Facebook 令牌方面做了一些更改： 

@Override
protected void onSaveInstanceState(Bundle outState) 
{
    super.onSaveInstanceState(outState);
    Session session = Session.getActiveSession();
    Session.saveSession(session, outState); // Saving Session
}

在您的活动中更改此内容并让我知道。
