html 高度 100% 被 webview 忽略

Question

webview 不理解什么 html 高度 100% 意味着它只是显示一个空白页面。但是，在移动浏览器中它工作得非常好。谁能帮我？我已经提出了很多建议，但都没有奏效。正如您在代码中看到的，我特意将 html 背景颜色设置为红色，以便我可以查看 html 文档是否确实在我的 webview 上。我根本看不到任何红色，它只是纯白色。

只有当我硬设置高度并且我不想那样做时它才有效。我的代码如下：

Answer 1

确保您的 webview 布局配置正确：

android:layout_height="ma​​tch_parent"

如果您使用 wrap_content，webview 本身将缩小到零，因此只显示空白页面。

Answer 2

在 IE 和 chrome 中显示为红色，我建议使用 height:100vh; 代替 height: 100%;，因为这会将 div 设置为视口高度的 100%。 div 标签不会自动获取视口的高度，您必须告诉它这样做。还删除了以下代码作为位置：相对；是用于 Tgas 而不是 .还从行标签中删除了高度样式。您可以在 css 中设置，但高度应为每一行自行设置。

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>

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

    <div class="row" >
        <div class="col-xs-12 txt-center"></div>
    </div>

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

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

    <div class="row" >
        <div class="col-xs-12 txt-center full-height">
            <button type="button" class="btn btn-login btn-md" data-toggle="modal" data-target="#loginModal">LOG IN</button>

Answer 3

我在这里遇到了同样的问题：

Android WebView: how to let the css use the entire height w/ position absolute?

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

我希望这就是你的问题。

无论如何，尝试为您的 WebView 设置一些边框，以查看它实际停止的位置。
