从资源可绘制文件夹在 Facebook 上分享图片 (post)

Question

我正在制作一个应用程序，我需要在 Facebook 时间轴上共享带有文本的图像。但是，使用我的代码，我可以将 link 共享到 facebook 墙上，但不能共享图像。我已经尝试了大部分堆栈溢出的代码。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;

public class 主要Activity 扩展 Activity {

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

ListView list;

 String[] ShareItemName ={

 "Dropbox",
 "Email",
 "Facebook",
 "Google Plus",
 "Twitter",
 "Whatsapp",

 };

 Integer[] ShareImageId={

         R.drawable.ic_dropbox,
         R.drawable.ic_email,
         R.drawable.ic_facebook,
         R.drawable.ic_googleplus,
         R.drawable.ic_twitter,
         R.drawable.ic_whatsapp,

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






    ShareOptionList=(Spinner) findViewById(R.id.spinner_ShareScore);
    ShareOption=getResources().getStringArray(R.array.ShareChooseOption);
    ArrayAdapter<String> adapter1=new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item,ShareOption);
    ShareOptionList.setAdapter(adapter1);

    ShareOptionList.setOnItemSelectedListener(new OnItemSelectedListener(){

        @Override
        public void onItemSelected(AdapterView<?> arg0, View arg1,
                int arg2, long arg3) {
            // TODO Auto-generated method stub
            int index=arg0.getSelectedItemPosition();
            Toast.makeText(getBaseContext(), "You select "+ ShareOption[index],Toast.LENGTH_LONG).show();
        }

        @Override
        public void onNothingSelected(AdapterView<?> parent) {
            // TODO Auto-generated method stub

        }



    });




    ShareListAdapter adapter=new ShareListAdapter(this, ShareItemName, ShareImageId);
    list=(ListView)findViewById(R.id.listview_share);
    list.setAdapter(adapter);

    list.setOnItemClickListener(new OnItemClickListener() {

        @Override
         public void onItemClick(AdapterView<?> parent, View view,
         int position, long id) {
         // TODO Auto-generated method stub
         String Selecteditem= ShareItemName[+position];

         Toast.makeText(MainActivity.this, Selecteditem, Toast.LENGTH_SHORT).show();

         if(Selecteditem=="Facebook"){  


            // if (driverStarScore == 1){
                 //Uri pngUri = Uri.parse("file//res/drawable/star_1.png");

                    facebook1.setClassName("com.facebook.katana", "com.facebook.katana.activity.composer.ImplicitShareIntentHandler");
                    facebook1.setAction("android.intent.action.SEND");
                    facebook1.setType("image/png");
                    facebook1.putExtra("android.intent.extra.TEXT", urlToShare);
                    startActivity(facebook1);

             } catch (Exception e) {
                    // If we failed (not native FB app installed), try share through SEND
                    Intent facebook = new Intent(Intent.ACTION_SEND);

            email.setType("message/rfc822");
            email.putExtra(Intent.EXTRA_EMAIL  , new String[]{"recipient@example.com"}); // if you want to add email address also.
            email.putExtra(android.content.Intent.EXTRA_TEXT, "Sample Text");
            email.putExtra(Intent.EXTRA_SUBJECT, "Driving Score Email");

            try {

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 开发者网站上找到有关如何 integrate it with your app and how to share 的文档。

注意：直接调用分享对话框，虽然可以，但不支持，随时可能中断，所以绝对不推荐。
