问题描述

我想检测，如果当前用户的手机有硬件键盘或仅在屏幕键盘。这可能与SDK？

I would like to detect if the current users phone has a hardware keyboard or only a on-screen keyboard. Is this possible with the SDK?

推荐答案

是，您可以。

取的<一个href="http://developer.android.com/reference/android/content/res/Configuration.html">Configuration使用对象

Configuration config = getResources().getConfiguration();

...然后看看<一href="http://developer.android.com/reference/android/content/res/Configuration.html#keyboard"><$c$c>keyboard领域。

如果他们看重的<一个href="http://developer.android.com/reference/android/content/res/Configuration.html#keyboard"><$c$c>keyboard是不是<一个href="http://developer.android.com/reference/android/content/res/Configuration.html#KEYBOARD_NOKEYS">KEYBOARD_NOKEYS,用户有硬件键盘。

If they value of keyboard is not KEYBOARD_NOKEYS, the user has a hardware keyboard.

请注意，由于 @Carl 说，在他的评论如下，用户可以在同时任何时候连接USB键盘您应用程序正在运行，从而导致键盘的值来改变。

Note that as @Carl says in his comment below, the user may attach a USB keyboard at any point while your app is running, causing the value of keyboard to change.
