最近在做播放器的时候遇到一个问题,在屏幕方向改变之后需要切换播放器全屏/非全屏的时候,在重写了onConfigurationChanged方法并在manifest.xml配置文件中添加 android:screenOrientation="sensor" android:configChanges="orientation|screenSize|smallestScreenSize|keyboard|keyboardHidden|navigation" 之后,在屏幕方向改变之后确实切换了播放器的方向,但是在我的程序中,需要一个播放器控制按钮,当用户点击按钮时手动切换播放器方向(即播放器全屏/小屏状态切换)和屏幕方向改变时自动切换两个功能并存;最开始想的是直接使用setRequestedOrientation()设置屏幕方向应该就OK了,但是发现这样做是行不通的.之后了解到因为setRequestedOrientation设置屏幕方向之后,比如说setRequestedOrientation(portrait)方法,就设定了屏幕方向是portrait,和在清单文件中配置android:screenOrientation="portrait"是同等的效果;也即不再响应屏幕方向改变,只支持portrait方向; 　　言归正转,说我的处理方法

Hi there i created a responsive mobile website using this: max-width(480px) {etc..} + <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no"> For every mobile device the website looks the same => great. But when i change to landscape there is more than 480px and the website-variation of the desktop displays. Is there any possibility to disable the auto-rotate or to show the portrait-mode on mobile-device even if there is more than 480px? Greetings You can try and target specific orientation with your media query: @media max-width(600px) and
