根据屏幕尺寸确定方向 [英] Have a fixed orientation based on screen size

问题描述

我有一个基于手机的Android应用程序，现在我将对其进行更新以支持平板电脑大小的屏幕(尤其是Galaxy Tab 10.1).我弄清楚了整个res/layout的内容，这很好.但是，我构建的应用在AndroidManifest.xml中具有固定的屏幕方向，设置为android:screenOrientation="portrait".

I have an Android app built on a phone that I am going to update now to also support tablet-sized screens (in particular Galaxy Tab 10.1). I figured out the whole res/layout thing, so that's fine. However, I built my app to have a fixed screen orientation in AndroidManifest.xml, set as android:screenOrientation="portrait".

现在，我要进行以下操作:对于每种屏幕尺寸，都必须具有 fixed (固定)方向，一种是纵向固定(布局较小)，另一种是横向固定.

Now, I want to have the following: have a fixed orientation for each screen size, the one fixed in portrait (layout-small) and the other as landscape.

使用res/layout-small-land和res/layout-large-port并没有达到我想要的效果，因为它仍然从纵向切换为横向并返回.更糟糕的是，当res/layout-small-land不存在时，当我将手机旋转到横向时，应用程序崩溃.

Using res/layout-small-land and res/layout-large-port doesn't do what I want, because it still switches from portrait to landscape and back. Worse even, the app crashes when I rotate my phone to landscape, because the res/layout-small-land doesn't exist.

我可以仅通过定义XML文件来执行此操作，还是必须添加代码?

Can I do this by just defining XML files, or do I have to add code?

推荐答案

您可以使用

Instead of fixing the orientation on the manifest, you could use setRequestedOrientation. On the onCreate method of each activity, check if you are on a tablet or smartphone and set the desired orientation.

另一个选项可以是为不同的屏幕尺寸创建多个APK ，根据您的需求.

Another option could be Creating Multiple APKs for Different Screen Sizes, depending on your needs.
