关闭全屏视图后的WebView，Webview会自动滚动到顶部 [英] WebView after closing fullscreen view, webview auto scrolls to top

问题描述

我有webveiw (具有全屏支持)分段. 问题是，当我关闭全屏时，webview会将其位置滚动到顶部. 注意:

I have webveiw (with fullscreen support) on the fragment. The issue is when i close fullscreen the webview scrolls it position to top. Noticed:

• 仅当应用FLAG_FULLSCREEN标志时，问题才会出现(但我需要将其应用为真正的全屏显示)
• 找到了可能的解决方案使用Java脚本，但没有答案.另外我也找不到用scrollTo和ect
之类的webview函数解决此问题的方法
• 当我添加小尺寸(高度100dp)的(全屏视图的安装)视图时，我看到Webview内容消失了.它在某处缓存了吗?可以禁用此功能吗?

• the issue appears only if apply FLAG_FULLSCREEN flag (but i need to apply it to have real fullscreen)
• found possible solution is to use java script, but there is no answer. Also i'm not found the way to resolve this with webview functions like scrollTo and ect
• when i add (instesad of fullscreen-view) view with small size (100dp height) i see that webview content is gone. Is it cached somwhere? Is it possible to disable this?

推荐答案

对我来说，问题是webview的高度为match_perent or wrap_content，并且在应用FLAG_FULLSCREEN webview之后失去了高度. 解决方案是先设置layoutParams.height = height，再设置FLAG_FULLSCREEN

For me the issue was that webview have match_perent or wrap_content in height and after applying FLAG_FULLSCREEN webview lose it height. solution was to set layoutParams.height = height before set FLAG_FULLSCREEN

因此，在这种情况下，"layoutParams.height"-布局高度设置，"height"-当前视图高度

so, in this case "layoutParams.height" - layout height settings, "height" - current view height
