ユーザーが選択できるボタンがいくつかあり、画像が表示されますが、前の画像を削除せずに、画像を積み重ねているようです。ここで同様の質問を見つけましたが、それでも機能しないようです。

これが私の完全なコードです：

およびxmlの場合：

                    android:layout_marginTop="20dp"
                    android:layout_below="@+id/samplea"
                    android:background="@drawable/samplebbutton" 
                    android:longClickable="true"/>

他のすべてのボタンに対して繰り返されます。

このimageViewのxmlに背景を設定しましたか？backgroundとsrc（imageResource）が異なるため、xmlで画像の背景を設定し、Javaコードでそのリソースを設定している場合は、複数の画像が表示されることがあります。
