和视频链接

请建议我任何可行的解决方案,谢谢

解决方法 当视频位于div中时,您应该在代码中添加以下行：

webVIEw.getSettings().setDomStorageEnabled(true);    webVIEw.getSettings().setAppCacheEnabled(true);    webVIEw.getSettings().setAppCachePath(getApplicationContext().getfilesDir().getabsolutePath() + "/cache");    webVIEw.getSettings().setDatabaseEnabled(true);    webVIEw.getSettings().setDatabasePath(getApplicationContext().getfilesDir().getabsolutePath() + "/databases");
