ViewPager를 사용하여 간단한 앱을 개발 중입니다. 웹 뷰에는 내용과 이미지가 있습니다. ViewPager에는 여러 페이지가 있으며 모든 페이지에는 동일한 데이터가 있습니다.이미지가 webview에로드되지 않습니다. ViewPager

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

HTML ...는 동일한 구조의 콘텐츠 (텍스트 + 이미지)의 다른 유형을 갖는
문제점 : 액티비티가 시작될 때, 영상이 표시되지 않는다. 확대/축소를 가볍게 두 드릴 때 이미지가 표시됩니다. 축소를 누르면 이미지가 표시되지 않습니다.
