this old question. came across it. here's take on answer future reference if interested. add:
<key android:codes="-1" android:keyicon="@drawable/sym_keyboard_shift" android:keywidth="12.5%p" android:keyedgeflags="left"/> to add shift key on left side instance. add onkey() method if:
else if (primarycode == -1){ caps = !caps; keyboard.setshifted(caps); mkeyboardview.invalidateallkeys() } where keyboard instance of keyboard inflated using 1 of xmls. instance:
keyboard = new keyboard(this, r.xml.lowercase); caps flag determines whether shift upper case or shift lower case. should shift keyboard when key clicked.
p.s should use switch case statement instead of if else statements.
