내 활동에 ViewPager가 있습니다. PagerAdapter로 어댑터를 설정했습니다.
어댑터 항목은 VideoViews 및 ImageViews입니다. 다른 활동에서 미리보기 이미지를 클릭하면 ViewPager가 나타납니다.
그러나 이미지 페이지를 선택하면 ViewPager 항목 (3) _left 및 활성 항목의 오른쪽 항목의 기본 인스턴스 수 때문에 비디오가 백그라운드에서 재생 중입니다.
ViewPager에서 이미지를 볼 때 동영상 재생을 처리하는 방법에 대한 아이디어.
내 이미지가 어떻게 표시되는지, 올바른 항목은 videoview 및 MediaController입니다. 
ViewPager와 3 개의 인스턴스를 한 번에 인스턴스화하면 왼쪽 이미지에서 비디오가 재생됩니다.
