Android Animation 드로잉, 왜 항상 두 번 촬영 ​​했나요?

Question

내 코드 :

<?xml version="1.0" encoding="utf-8"?> 
<animation-list xmlns:android="http://schemas.android.com/apk/res/android" 
    android:oneshot="true"> 
    <item android:drawable="@drawable/bubble0" android:duration="500" /> 
    <item android:drawable="@drawable/explode1" android:duration="500" /> 
    <item android:drawable="@drawable/explode2" android:duration="500" /> 
    <item android:drawable="@drawable/explode3" android:duration="500" /> 
    <item android:drawable="@drawable/explode4" android:duration="500" /> 
    <item android:drawable="@drawable/explode5" android:duration="500" /> 
</animation-list>

:이 애니메이션은 두 번 해고,하지만 이벤트가 있는지 확인 시작() 메서드를 한 번만 트리거 될 수 있도록하기 위해 시도했지만 애니메이션이 여전히 두 번 수행됩니다 된 것 같다

Help!

Answer 1

당신에게 조금 늦을 지 모르지만, 같은 문제가 생겼을 때이 질문을 보았습니다.

애니메이션을 두 번 실행하는 이유는보기의 가시성을 VISIBLE로 변경하면 애니메이션이 처음부터 다시 시작되기 때문입니다.

해결 방법은 애니메이션을 시작하거나보기 가시성을 View.VISIBLE로 변경하는 것입니다.
