Android 如何在网络视图中内联播放html5视频?
我需要在网络视图中内联播放html5视频。我发现了一种本应有效的技术,但它只能偶尔有效(见问题的结尾)。当它不工作时,不会调用onShowCustomView。有没有人能找到这样做不起作用的原因或提出替代方案Android 如何在网络视图中内联播放html5视频?,android,html,video,webview,Android,Html,Video,Webview,我需要在网络视图中内联播放html5视频。我发现了一种本应有效的技术,但它只能偶尔有效(见问题的结尾)。当它不工作时,不会调用onShowCustomView。有没有人能找到这样做不起作用的原因或提出替代方案 package com.richcollins.VideoView; import java.io.ByteArrayOutputStream; import java.io.InputStream; import android.app.Activity; import androi

请参阅ICS应用程序的示例,该应用程序在webview中使用HTML5来显示视频,希望它能解决您的问题
如果要“伪造”自动播放(在webview中被阻止),则需要从page onload事件触发.play()。如果您想浏览播放列表,则需要捕获并响应OneDed事件。您签出了吗?我的答案如下:
