keyboard

问题 Good afternoon. I have an EditText that may contain numbers and letters. By deploying the keyboard, is there any way to deploy it in numerical form?. If I put the EditText as numeric I do, but that's not my case. Thank you very much. 回答1: Try this: EditText myEditText = (EditText)findViewById(R.id.myEditText); myEditText.setInputType(InputType.TYPE_NUMBER_FLAG_DECIMAL); Then set it back to alphanumeric when you are done with numeric.. 回答2: You can: Hide/Show different EditTexts that have

问题 I am looking for a solution to programmatically hold a keyboard key down during some time (I don't know how many time). I think that if I send a WM_KEYDOWN message the key will be held down until WM_KEYUP is send, but I am not sure. I would test it. But I need to go and I don't have much time. I want to see if someone already tested this. Here is an other question I posted, related to this one. I want to make a virtual keyboard. Do I need to send WM_KEYDOWN to the current active window or

问题 Found bug Java Bug "CAPS" doesn't update. I want it to be actively checking the locking state but it only checks it once and stores true/false in "CAPS" but if you hit caps lock it doesn't change the boolean stored in CAPS.

问题 i want to get a cursor position from UITextview, i have implement the code in How to find a pixel-positon of a cursor in UITextView? post, the algorithm is based on algorithm in Pixel-Position of Cursor in UITextView. my problem is, i can't get the selectedRange.location value after keyboard appear in the 2nd time, cause it always tell that the value of location is 2147483647, which means not found.

问题 Is there any way to prevent a key like F1 from being pressed? After a short search, I found this website: http://www.cambiaresearch.com/c4/789d4357-60e9-4dbd-8e8c-affb2ebd6960/How-Do-I-Suppress-a-Keystroke-in-a-Browser-Input-Box-Using-Javascript.aspx This way one can suppress keys like 'a' being pressed (it does not get put in the textbox), but keys like 'tab', 'F1' etc. are still working, i.e. the focus does change and, as I'm using Google Chrome, the Chrome help website does pop up. I'm

问题 Given a UIViewController , I would like to receive text input only from the external keyboard. Think UIKeyCommand but for any character (not just 'modified' ones). However, when I try to implement that using UIKeyInput , it seems that iOS desperately wants to display a keyboard if there is no external one connected. Is there any way to circumvent that? Specifically, to have the options to receive keystrokes from the keyboard if, and only if, one is connected? 回答1: After fiddling with a iPad
