HTML高度100%被webview忽略

webview不理解html高度100%意味着什么，它只是显示一个空白页面。然而，在移动浏览器中，它工作得很好。有人能帮我吗?我听了很多建议，但没有一个奏效。正如你在代码中看到的那样，我故意将html背景色设置为红色，这样我就可以看到html文档是否确实在我的webview上。我根本没看到红色，只有纯白色。

它只工作，如果我硬设置高度，我不想这样做。我的代码如下:

<!DOCTYPE html>

确保你的webview布局配置正确:

android: layout_height = " match_parent "

如果你使用wrap_content， webview本身将收缩为零，因此只显示空白页。

在IE和chrome中显示红色，我建议使用height:100vh;代替height: 100%;，因为这会将div设置为视图端口高度的100%。div标签不会自动获取视图端口的高度，您必须告诉它这样做。还删除了以下代码position:relative;是为了Tgas而不是。还从行标签中删除了高度样式。你可以在CSS中设置，但是每一行的高度应该自己设置。

html{
   margin:0;
   padding:0;
    
}
body {
   font-family: 'Titillium Web', sans-serif;
   width: 100%;
   background-color:red; /*#E9E9E9;*/
   
}
.cont-height {
height: 100vh;
}

<div  class="container-fluid login-container cont-height">
    <div class="row" >
        <div class="col-xs-12 txt-center full-height"></div>
    </div>

我在这里遇到了同样的问题:

Android WebView:如何让css使用整个高度w/位置绝对?

我回答了自己的问题，问题是使用alignParent而不是match_parent。

我希望这就是你的问题所在。

无论如何，试着给你的WebView设置一些边框，看看它到底停在哪里
