As the title says, I want to bring up the keyboard when I click/tap on the EditText. I've looked at other questions asking for the same thing but the answers just aren't working for me. I don't think the other questions are trying to do this in the onCreate() method and I don't think that they're using this answer for not focusing on the EditText when the app begins. I've added a list of code segments of what I tried and didn't work to avoid redundant answers.

P.S. I'm trying to bring up the keyboard with numbers only, and figure out how how to close it and execute it too.
You are not seeing the inputEditText because the AutoCompleteTextView control is
overlapping it. Try putting the inputEditText before the autotext and you will see the keyboard with numbers only. I also added android:orientation="vertical" to your XML.
