问题
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?
回答1:
Yes, you can.
Fetch the Configuration object using
Configuration config = getResources().getConfiguration();
...and then look at the keyboard field.
If they value of keyboard is not KEYBOARD_NOKEYS, the user has a hardware keyboard.
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.
