"If all you are wanting to do is change the color of one key, why don't you
just subclass KeyboardView and override the following methods:"
Hmm... that's a possibility. If I can change mKeyBackground. I tried:
@Override
public void invalidateKey(int keyIndex) {
mKeyBackground = getResources().getDrawable(R.drawable.key_space);
super(keyIndex);
}
But I get:
[javac] Compiling 2 source files to
/home/trans/workspace/microboard/bin/classes
[javac]
/home/trans/workspace/microboard/src/com/tabcomputing/android/microboard/PhoneticKeyboardView.java:45:
cannot find symbol
[javac] symbol : variable mKeyBackground
[javac] location: class
com.tabcomputing.android.zenboard.PhoneticKeyboardView
[javac] mKeyBackground =
getResources().getDrawable(R.drawable.key_space);
[javac] ^
Am I wrong that protected variables should be accessible in the subclass?
