问题 I'm doing some edits to an input device driver in an android kernel. This device has a limited range of keybits and evbits enabled. What I want to do is to create a new /dev/input event node that is not related to any physical device, with more keybits and evbits enabled, so that I can send real input signals from the physical driver to the userspace, in the userspace I listen to them and when received I can inject input events to the "virtual" driver writing to its event node.

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,

问题 I have an activity with a form in it. Because the form is quite long, I've used a scrollview. The problem is that the scrollview doesn't change when the keyboard is up.

问题 The idea is to take a user voice input on the press of a button and pass it to the search inside the app. Because of device limitations we are using the SearchViewCompat instead of the useful SearchView. I have been able to grab the voice output using this link, but there is not a simple way to pass the text to the search bar this way. The search view itself shows as a view (so no setText()), but if I can just say "use mic key on keyboard" or something as soon as the searchbar comes up, I

问题 I have a action bar search widget that offers search suggestion too. When the user types in a query and submits it or chooses a search suggestion, the keyboard doesn't disappear. How can I resolve this issue? I haven't been able to figure out how to hide the keyboard upon search submit or suggestion choose. Thank you. 回答1: To hide the input method editor, use InputMethodManager : InputMethodManager imm= (InputMethodManager)getSystemService(INPUT_METHOD_SERVICE); imm.hideSoftInputFromWindow(v
