獲取RawContact照片

我知道這是可能使用類似得到聯繫人的照片：獲取RawContact照片

public InputStream getContactPhotoInputStream() throws IOException { 
     Uri uri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_URI, String.valueOf(mContactId)); 
     InputStream is = ContactsContract.Contacts.openContactPhotoInputStream(contentResolver, uri); 

     return is; 
}

但現在我需要訪問所有RawContact的照片（有一個的）。但我不能。從ContactsContract.RawContacts.DisplayPhoto文檔中，照片保存爲文件，縮略圖在Data表中保存爲Blob。我可以通過對數據庫的簡單查詢獲得縮略圖照片並檢索Blob，但現在我需要原始尺寸的照片，並且找不到獲取它的方法。我無法在google上找到有關android文檔的任何信息。

我試過這種方法（改編自保存照片文件）來獲取照片文件，但沒有成功。

public InputStream getRawContactPhotoInputStream() throws IOException 
    { 
     Uri rawContactPhotoUri = Uri.withAppendedPath(
       ContentUris.withAppendedId(RawContacts.CONTENT_URI, Long.parseLong(mRawContactId)), 
       RawContacts.DisplayPhoto.CONTENT_DIRECTORY); 

     AssetFileDescriptor fd = contentResolver.openAssetFileDescriptor(rawContactPhotoUri, "rw"); 
     InputStream is = fd.createInputStream(); 

     fd.close(); 

     return is; 

    }

我得到這個在logcat的：

很多四處，詳盡地尋找Android的源代碼後，我發現了一種從原始取得聯繫的形象。

使用Android的本機代碼來獲取它，我做了我自己的解決方案（我的問題是獲取原始聯繫人的圖像URI，我找不到獲取它的方法）。所以從這裏public static boolean savePhotoFromUriToUr我這樣做：

public InputStream getBitmapFromUri(String rawContactId) throws FileNotFoundException { 

     final Uri photoUri = Uri.withAppendedPath(
       ContentUris.withAppendedId(RawContacts.CONTENT_URI, Long.valueOf(rawContactId)), RawContacts.DisplayPhoto.CONTENT_DIRECTORY); 
     final InputStream imageStream = contentResolver.openInputStream(photoUri); 

     return imageStream; 
}

所以這裏是，如何讓原料接觸的照片。
