如何分享應用程序到Facebook的特定文本？

Question

我試過這個代碼， 我選擇了Facebook應用程序並轉到了發佈頁面，但所選文字並未顯示。

public void onShareClick(View v){ 
    List<Intent> targetShareIntents=new ArrayList<Intent>(); 
    Intent shareIntent=new Intent(); 
    shareIntent.setAction(Intent.ACTION_SEND); 
    shareIntent.setType("text/plain"); 
    List<ResolveInfo> resInfos=getPackageManager().queryIntentActivities(shareIntent, 0); 
    if(!resInfos.isEmpty()){ 
     System.out.println("Have package"); 
     for(ResolveInfo resInfo : resInfos){ 
      String packageName=resInfo.activityInfo.packageName; 
      Log.i("Package Name", packageName); 
      if(packageName.contains("com.facebook.katana")){ 
       Intent intent=new Intent(); 
       intent.setComponent(new ComponentName(packageName, resInfo.activityInfo.name)); 
       intent.setAction(Intent.ACTION_SEND); 
       intent.setType("text/plain"); 
       intent.putExtra(Intent.EXTRA_TEXT, "Text"); 
       intent.putExtra(Intent.EXTRA_SUBJECT, "Subject"); 
       intent.setPackage(packageName); 
       targetShareIntents.add(intent); 
      } 
     } 
     if(!targetShareIntents.isEmpty()){ 
      System.out.println("Have Intent"); 
      Intent chooserIntent=Intent.createChooser(targetShareIntents.remove(0), "Choose app to share"); 
      chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, targetShareIntents.toArray(new Parcelable[]{})); 
      startActivity(chooserIntent); 
     }else{ 
      System.out.println("Do not Have Intent"); 
      showDialaog(this); 
     } 
    } 
} 

爲什麼選擇的文本不能共享在Facebook上顯示？我閱讀Facebook的政策，他們不允許這樣做，但其他應用程序能夠這樣做。有什麼方法可以實現這一目標嗎？

試試這個：

public void setupFacebookShareIntent() { 

     ShareDialog shareDialog; 

     FacebookSdk.sdkInitialize(getApplicationContext()); 
     shareDialog = new ShareDialog(this); 

     ShareLinkContent linkContent = new ShareLinkContent.Builder() 
       .setContentTitle("YOUR TITLE") 
       .setContentDescription("YOUR DESCRIPTION") 
       .setContentUrl(Uri.parse("http://xxxx.com/")) 
       .setImageUrl(Uri.parse("http://xxxx.com/")) 
       .build(); 

     shareDialog.show(linkContent); 
    }
