keyboard

问题 I'm trying to write my own "keyboard driver" (without actually writing a kernel module), by grabbing the keyboard at what I assume is the lowest level of abstraction in userland: /dev/input/event* . The following code does the grabbing, provided you change the first ocurrence of ioctl(fd, EVIOCGRAB, UNGRAB) to ioctl(fd, EVIOCGRAB, GRAB) . // gcc main.c -o main #include <stdio.h> #include <unistd.h> #include <string.h> #include <linux/input.h> #include <fcntl.h> #include <errno.h> #define EXIT

问题 I'm trying to provide a modified view for a custom Android keyboard in fullscreen mode. Therefor I'm trying to replace the extract view. In the documentation I found the following method: setExtractView(View view) - so I assume it's a public API call. However, as you can see from the Android OS source code (snipped pasted below) it lets me only access a view that has view items with id's within the com.android.internal.* space. Otherwise I will, of course, get a NullPointerException. public

问题 This question is a possible duplicate of this and this thread. But since none of them have provided a clear solution for my problem, I'm asking it again. My required task is to connect 2 Keyboards via USB and then manage the inputs of each Keyboard separately through a Java Application. This requirement has been answered into some progress in the first thread I have mentioned above by @nan but his solution did not work accurately for me. You can find his blog post on his solution for this

问题 This is a question in the C programming language. How do I directly read the data in the keyboard buffer? I want to directly access the data and store it in a variable. Of what data type should the variable be? I need it for an operating system our institute is currently developing. It's called ICS-OS and I am not quite sure about the specifics. It runs on x86, 32-bit machines (we run it on QEMU in a Linux box). Here is the link for the Google Code http://code.google.com/p/ics-os/. I hope

问题 In iOS 8, Apple has given developers the ability to create custom keyboards. In the documentation, Apple states that you should create a new keyboard if you want to support a language that iOS does not currently support. Therefore, if you are able to support new languages, are you able to create a keyboard that contains new emoji characters? I would assume that by Apple stating that you can support a new language, they would expect there to be custom characters involved. If including custom

问题 I just tested Cordova 3.1 with a sample iOS app and experienced several keyboard issues. App settings: Xcode 5 Status bar is hidden Landscape mode config.xml Issues: All versions: when focus on an input field then whole view is pushed up including navbar. iOS5/6: tap on an input field to open keyboard, then a black gap is briefly displayed at top of screen before keyboard pushes whole view up (is it status bar?) iOS7: there is no black gap like #2 issue, but there are other issues: I still
