將聯繫人圖像加載到位圖中

Question

我用來從手機號獲取聯繫人圖像縮略圖的Uri的功能。 ：

public static Uri getPhotoURIFromAddress(Context activity, String address) { 
    String contactId = getContactIdFromAddress(activity, address); 

    ContentResolver contentResolver = activity.getContentResolver(); 
    try { 
     Cursor cursor = contentResolver 
       .query(ContactsContract.Data.CONTENT_URI, 
         null, 
         ContactsContract.Data.CONTACT_ID 
           + "=" 
           + contactId 
           + " AND " 

           + ContactsContract.Data.MIMETYPE 
           + "='" 
           + ContactsContract.CommonDataKinds.Photo.CONTENT_ITEM_TYPE 
           + "'", null, null); 

     if (cursor != null) { 
      if (!cursor.moveToFirst()) { 
       return null; // no photo 
      } 
     } else { 
      return null; // error in cursor process 
     } 
     cursor.close(); 

    } catch (Exception e) { 
     e.printStackTrace(); 
     return null; 
    } 

    Uri person = ContentUris.withAppendedId(
      ContactsContract.Contacts.CONTENT_URI, Long.valueOf(contactId)); 
    return Uri.withAppendedPath(person, 
      ContactsContract.Contacts.Photo.CONTENT_DIRECTORY); 
} 

將在形式返回一個URI：

content://com.android.contacts/contacts/799/photo 

現在，如果我與setImageUri（URI）功能的ImageView的使用這個開放的，它的工作原理。

但加載位圖是一個問題。我使用的功能是：

public static Bitmap getContactBitmapFromURI(Context context, Uri uri) { 
     InputStream input = ContactsContract.Contacts 
       .openContactPhotoInputStream(context.getContentResolver(), uri); 
     if (input == null) { 
      return null; 
     } 
     return BitmapFactory.decodeStream(input); 
    } 

它總是崩潰。 LogCat是：

請大家幫忙！

我不認爲你應該通過照片的URI來openContactphotoinputstream。你只需要傳遞聯繫人的URI就可以獲得位圖。

Uri uri = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, id); 
    InputStream stream = ContactsContract.Contacts.openContactPhotoInputStream(
      mContext.getContentResolver(), uri); 

或者，如果你要通過聯繫人照片的URI，那麼你可以使用

public static Bitmap getContactBitmapFromURI(Context context, Uri uri) { 
     InputStream input = context.getContentResolver().openInputStream(uri) 
     if (input == null) { 
      return null; 
     } 
     return BitmapFactory.decodeStream(input); 
    }
