새 이미지를 선택한 후 이미지 삭제

Question

사용자가 선택할 수있는 몇 개의 버튼이 있는데 이미지를 표시하지만 이미지를 서로 쌓아 놓고 이전 이미지를 삭제하지는 않습니다. 나는 비슷한 질문을 여기에서 발견했다. 그러나 그것은 아직도 일하는 것처럼 보이지 않는다.

및 XML에 대해 : 그것은 단지 다른 모든 버튼에 대해 반복

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"

</RelativeLayout> 
</ScrollView>

        android:background="@drawable/samplebbutton" 
        android:longClickable="true"/> 

여기 내 전체 코드입니다.

Answer 1

이 imageView의 XML 배경을 설정 했습니까? 배경과 src (imageResource)가 다르기 때문에 ... xml에 이미지의 배경을 설정하고 Java 코드에서 리소스를 설정하는 경우 예 하나 이상을 볼 수 있습니다.
