onKeyDown in a service? (Global Hot Keys)

由 青春壹個敷衍的年華 提交于 2019-11-27 07:51:55
What I'm basically trying to achieve is custom global hot keys or in other words 'things will happen when I push certain buttons no matter which program is currently on top'. I assume a service is needed. I have a quick and dirty test that just tells me what has been pressed that will work if it is the active window. public boolean onKeyDown(int keyCode, KeyEvent event) { char pop; pop = (char)event.getUnicodeChar(); Toast.makeText(this, Character.toString(pop) , Toast.LENGTH_SHORT).show(); return super.onKeyDown(keyCode, event); } But obviously if I change window or go into a text box it

onKeyListener not working with soft keyboard (Android)

由 做~自己de王妃 提交于 2019-11-27 04:24:42
I am using onKeyListener to get the onKey events. It works fine with the normal keyboard. But it does not work with soft keyboard. I am only able to get onKey events for numerics and not alphabets. Is there any workaround to solve this? Any kind of help will be greatly appreciated. I don't believe an OnKeyListener gets called at all with the software keyboard. It has something to do with the software keyboard being an IME device and IME devices possibly being things other than keyboards. It seems to make onKeyListener pretty much useless though, since it only works on phones with hardware

How to disable facebook hotkeys with Chrome extension?

由 落爺英雄遲暮 提交于 2019-11-27 01:26:30
问题 I have created a Chrome extension that uses the hotkeys [Alt]+[0...9] only to discover facebook uses the same hotkeys. Is there any way possible my extension could disable facebook's hotkeys so that mine fire alone? I'm fairly certain I have identified the code facebook uses to implement their [Alt]+[0...9] hotkeys: document.documentElement.onkeydown=function(a){a=a||window.event;var b=a.target||a.srcElement;var c=a.keyCode==13&&!a.altKey&&!a.ctrlKey&&!a.metaKey&&!a.shiftKey&&CSS.hasClass...

WPF: OnKeyDown() not being called for space key in control derived from WPF TextBox

由 早过忘川 提交于 2019-11-26 21:46:27
问题 In a WPF application, I have a control that I have derived from TextBox like this: public class SelectableTextBlock : TextBox { protected override void OnKeyDown(KeyEventArgs e) { base.OnKeyDown(e); e.Handled = false; } } The OnKeyDown method is not called when entering a space into the TextBox, nor when hitting Backspace, but does fire for other input including normal printable characters (e.g. 'a') and modifier keys (e.g. ). I'm using this control with IsReadOnly set to true so I can

onKeyListener not working on virtual keyboard

由 徘徊边缘 提交于 2019-11-26 18:25:57
问题 I don't understand why this piece of code is not working. Only backspace and return key are detected. Listener doesn't fire for any other key. My device is Nexus One. I tried to override activity's OnKeyDown method and that's even worse. The only detected button was hardware back button. I am seeing around a suggestion to use TextWatcher and onTextChanged, while that might work in some cases, it's not a real work around. For example, if textbox is empty, you won't detect if user press

问题 I have a function that is triggered by the onkeydown event of a textbox. How can I tell if the user has hit either the backspace key or the del key? 回答1: Try this: document.addEventListener("keydown", KeyCheck); //or however you are calling your method function KeyCheck(event) { var KeyID = event.keyCode; switch(KeyID) { case 8: alert("backspace"); break; case 46: alert("delete"); break; default: break; } } 回答2: Nowadays, code to do this should look something like: document.getElementById(
