QUESTION
I have a question.
I'm making Keystroke dynamics app on android devices.
For now, I make an Activity with measure string and EditText
. I want to catch KeyDown
and KeyUp
events on software keyboard.
My question is, what is the best way to catch KeyUp
and KeyDown
on Android with Java? If EditText
is a good choice? If it have methods to catch any keypresses?
EDIT
I want to detect keys from string above and measure time of pressing it, (start measure on KeyDown
and stop on KeyUp
for example). If its possible, i want to block other keys that is not mentioned in my test string
(its 9RJhl6aH0n
, like in my screen)
EDIT2
What i achieve so far is something like this, but my app crashes on default
, when I coded line: measureText.setText("")
. It works pretty ok, but still it won't trigger on KeyDown
(or KeyPress
). These methods run only on KeyUp
, when user just typed letter. Order is very important!

ANSWER
Answered 2019-Jan-26 at 21:44A null view is usually a result of your layout not containing a view with the id you specified in findViewById(). Therefore findViewById() returns null and the variables are remaining null when onResume() is called. Double check your view ids in main_activity.xml.
It's also possible that the full content view is not available in onCreate() if you are using a more complicated layout. If you find that your views are null in onCreate(), try moving findViewById() to a later point in the lifecycle.
