Android - Get keyboard key press

For handling hardware keys and Back key you could use dispatchKeyEvent(KeyEvent event) in your Activity

@Overridepublic boolean dispatchKeyEvent(KeyEvent event) {    Log.i("key pressed", String.valueOf(event.getKeyCode()));    return super.dispatchKeyEvent(event);}

UPD: unfortunately you can't handle soft keyboard events (see Handle single key events), unless you develop your own custom keyboard (follow the link to learn how Creating input method).

With the hint of vasart i can get the KeyPress event. To make the keycode printable i have used the function getUnicodeChar passing it the meta button state then just a char cast solve the problem.

This is the working code:

@Overridepublic boolean dispatchKeyEvent(KeyEvent KEvent) {    int keyaction = KEvent.getAction();    if(keyaction == KeyEvent.ACTION_DOWN)    {        int keycode = KEvent.getKeyCode();        int keyunicode = KEvent.getUnicodeChar(KEvent.getMetaState() );        char character = (char) keyunicode;        System.out.println("DEBUG MESSAGE KEY=" + character + " KEYCODE=" +  keycode);    }    return super.dispatchKeyEvent(KEvent);}

Of course this work only with ASCII character.

There are no option to handling key press events on soft keyboard (an on-screen keyboard) only from a hardware keyboard.

Note: When handling keyboard events with the KeyEvent class and related APIs, you should expect that such keyboard events come only from a hardware keyboard. You should never rely on receiving key events for any key on a soft input method (an on-screen keyboard).
