[android-developers] Re: Simple Key Event Questions
okay thanks Dianne. You have been great help! One more question(sorry to keep troubling you): Is there any way to have my OWN softkeyboard just for one application. Eg: I have an EditText. I want a custom softkeyboard to show only when I edit this text box only in my app. I dont want it to be used for any other apps. OR is there is way to disable the popping up of the system IME when I click an EditText? Cheers, Earlence On Sep 7, 10:34 am, Dianne Hackborn hack...@android.com wrote: I've told you what there is.

You can use they keyboard class to implement your own IME inside of the app. You can't do this with the IME framework, since that is global.

KeyListener is (generally) only for physical keyboards.

Re: [android-developers] Re: Simple Key Event Questions
You can override EditText to return your own InputConnection. But... if you want KeyEvents, you won't get KeyEvents. Period. There are no KeyEvent objects involved in this ANYWHERE. At all. The user is touching on the screen (that is a touch event). The IME turns that into an edit operation on the TextView (that is a call to InputConnection). No KeyEvent. What you are claiming to want to do simply doesn't make sense. Let's back up here and see what you are actually trying to accomplish? Not timing between two key events. What is the goal you are trying to achieve? On Sat, Sep 4, 2010 at 6:55 AM, Tez earlencefe...@gmail.com wrote: How do I intercept the InputConnection Calls? Would I have to modify the IME or use a custom one? Having text change listeners would not be of use as I need key timing information. This I can only get thru KeyEvents.

When I use the soft keyboard to input text, my listener is not called. How Do I intercept these events? InputConnection is how edit operations are delivered through an IME. These will appear as direct edits of the text in the EditText, so to watch that you either need to intercept the InputConnection calls or have listeners for text changes. 2. How do I measure time interval between KeyEvents. The methods are confusing and documentation is not good. Plz put pseudo-code here. Er... there is nothing really to document here. SystemClock.uptimeMillis() returns the current time in what are probably appropriate units for you. Call it at the points you are interested in. Compare the values.
