Question

我正在制作一个应用程序，我需要在Facebook时间轴上与文本共享图像。然而，使用我的代码，我可以共享Facebook墙的链接，但不能共享图像。我已经尝试了大部分堆栈溢出代码。但还没有成功。这是我的代码。

MainActivity.java

 package com.example.test2;



import com.facebook.android.Facebook;

import android.net.Uri;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.content.SharedPreferences;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.AdapterView.OnItemSelectedListener;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.Spinner;
import android.widget.Toast;

公共类MainActivity扩展了Activity {

String[] ShareOption;
Spinner ShareOptionList;
int driverStarScore = 1; //2 or 3 ...
Facebook facebookClient;    
SharedPreferences mPrefs;

ListView list;

 String[] ShareItemName ={

 "Dropbox",
 "Email",

与Facebook分享内容的推荐且更简单的方法是使用Android Facebook SDK。您可以在Facebook Developer网站上找到有关如何integrate it with your app和how to share的文档。

注意：直接调用共享对话框虽然可以，但是不受支持，并且可以随时中断，所以绝对不建议这样做。
