Как решить: Бинарная строка XML-файла # 8: Ошибка раздувания класса

Question

Мое приложение состоит в перемещении изображения, когда пользователь говорит. Я сделал это, но у меня проблема, когда я пытаюсь установить изображение в качестве фона для своего приложения. Я пытаюсь сделать это с помощью xml-файла, но я получаю класс раздувания Error. Кто-нибудь может мне помочь? Заранее спасибо

Line 8 в классе XML является:

<com.example.prova1.MoveBalloon.DrawBalloon 
     android:id="@+id/drawBalloon1" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:layout_alignParentTop="true" 
     android:layout_centerHorizontal="true" 
     android:layout_marginTop="182dp" /> 

и LogCat сказал:

Это мой новый xml-файл:

    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    tools:context=".MoveBalloon" 
     android:background="#00000000" > 

    <view class="com.example.prova1.MoveBalloon$DrawBalloon" 

     android:id="@+id/drawBalloon1" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:layout_alignParentTop="true" 
     android:layout_centerHorizontal="true" 
     android:layout_marginTop="182dp" 
     /> 

</RelativeLayout> 

Answer 1

вы должны использовать класс attribite

посмотреть Error referencing an inner class View in layout/main.xml
