如何让我的应用适合整个屏幕

Question

我正在不同的电视屏幕上开发一个应用程序，除 LG 32LJ57 WebOS 外，在每个平台上一切正常，布局由于某种原因不适合整个屏幕，我尝试了不同的东西， 1) 添加元标记以适合屏幕，2) 增加分辨率（注意默认分辨率为 1920x1080），但没有任何变化，而且，当我在 LG webOS 模拟器上测试时，一切都非常适合但不适合实际屏幕，感谢您协助

Answer 1

这是我用于我的应用程序的元标记，请尝试添加 viewport-fit=cover

<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, minimum-scale=1, user-scalable=no, minimal-ui, viewport-fit=cover">

Answer 2

请添加您的 CSS，包含的行 div 是否有宽度？使用 container-fluid 包含 bootstrap 中的行：

https://getbootstrap.com/docs/4.0/layout/overview/ - 尝试使用 class 容器流体将行包装在 div 中：

<div class="container-fluid">
    <div class="row h-100 align-items-center text-center">
        <div class="col-xl-5 offset-xl-6">
            <div class="row row1">
                <div class="col-xl-4">
                    <a id="0" class="logo" onclick="playMedia(0)"><img 
                           src="./img/Kids.png" class="img-fluid"></a>
                </div>
                <div class="col-xl-4">
                    <a id="1" class="logo" onclick="playMedia(1)"><img 
                           src="./img/sport.png" class="img-fluid"></a>
                </div>
                <div class="col-xl-4">

Answer 3

可能电视无法处理1080分辨率的应用程序(http://webostv.developer.lge.com/discover/specifications/webos-tv-platform/supported-app-resolution/)

我猜你已经用 'resolution': '1920x1080' 配置了 appinfo.json，但你还设置了设备宽度为 1280 (content ="width=device-width") 的 HTML 应用程序，所以基本上电视正在尝试使用两种不同的尺寸

要支持这些电视，您必须发布两个具有两个不同 appinfo.json 的应用程序，一个用于 1080 ("resolution": "1920x1080")，另一个用于 720 ("resolution": "1280x720")
