私は最初の Android プロジェクト/最初の Java プロジェクトを構築しています。ユーザーがクリックできる複数のボタンが上にある画像を描画しようとしています。ただし、ボタンをズームインすると、希望どおりに拡大され、背景の画像との相対位置が維持されますが、onClickListener に応答しなくなります。

XML コード

    android:id="@+id/DeckLayout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:clickable="true"
    android:gravity="center_horizontal" >

    <!-- <CustomDrawableView android:layout_height="fill_parent"
               android:layout_width="fill_parent"
              />  -->

    <ImageView
