Apps SoftKeyboard without any EditText causes strange behavior

[Jonas Oliveir]

I had an activity that opens already with the keyboard opened because I use the attribute android:windowSoftInputMode="stateAlwaysVisible" at AndroidManifest. But in this activity I don't have any Edit Text (only one button) and I need to read each character typed (once per time) by user, but I really just need one character and my app will auto complete the word. So I had overridden the dispatchKeyEvent to read each character.

The problem is that since the keyboard is being showed and there is no one Edit Text, when click in any character Android OS kind selects the button (or any other view) on screen. This selection is kind I was using a D-pad. And if the back button is pressed it will "select" any other view from back activity.

I think that since there is no Edit Text to works with keyboard the activity does not know how to handle the characters typed.

I had attached the project on thread and at Tiny server a simple project with two activities that can be used as sample to reproduce the issue: http://s000.tinyupload.com/download.php?file_id=70317553185010262971&t=7031755318501026297148955

Also had attached a screenshot at TinyPic:
