keyboard

问题 I've developed custom keyboard on android, and I want to add a button to enable my keyboard and redirect the user to the page of virtual keyboards or to page manage keyboards so that the user can just turn on my keyboard from there, for example similar to the one in "a.i.typekeyboard", kindly see the screenshot. 回答1: Just open input method settings activity using Intent . Intent enableIntent = new Intent(Settings.ACTION_INPUT_METHOD_SETTINGS); enableIntent.setFlags(Intent.FLAG_ACTIVITY_NEW

问题 I am writing a Key board emulator program in Linux, As a start I was able to render key strokes into X11 window but this is not working in virtual terminals and try out a different way. I referred to http://thiemonge.org/getting-started-with-uinput and tried with uinput kernel module. According to the tutorial key strokes can be injected as a uinput event and I wrote below code accordingly. #include <stdio.h> #include <stdlib.h> #include <string.h> #include <unistd.h> #include <fcntl.h>

问题 I need to detect a keypress in a console application, without prompting the user. Basically, my app is normally a daemon that listens to a special input device, but i need to simulate it on a dev box using the keyboard in interactive mode. How can I do this? - Im on a Linux system. 回答1: If you can't block while waiting for input, then you can use e.g. select to check if the STDIN_FILENO file descriptor is ready for reading, and if it is then you can use normal input functions ( scanf , fgets

问题 I'm working with WPF KeyDown event (KeyEventArgs from Windows.Input). I need to recognize when user pressed F1 alone and Ctrl+F1. private void Window_KeyDown(object sender, KeyEventArgs e) { if (e.Key==Key.F1 && Keyboard.IsKeyDown(Key.LeftCtrl)) { MessageBox.Show("ctrlF1"); } if (e.Key == Key.F1 && !Keyboard.IsKeyDown(Key.LeftCtrl)) { MessageBox.Show("F1"); } } My problem is that when I press Ctrl+F1 plain F1 messagebox would fire too. I tried to add e.Handled to Ctrl+F1 case, but it doesn't

问题 Although I've searched, I'm confused about how best to approach this. I have a tableView where the bottom cell is an input to the list, in the same way apple reminders work. When there are too many items on the list, the keyboard covers the list and I can't see what I'm typing. My thought it I need to change the physical size of the table view and ensure it is scrolled to the bottom when the keyboard shows. Some have said keyboard observers but the majority of code I've found for this is out
