Hi-- I am not very experienced with Java, and I am confused about overriding
a method. I am trying to override the OnBufferDraw() method by extending
KeyboardView, like this:
public class PhoneticKeyboardView extends KeyboardView {
@Override
private void onBufferDraw() {
if (mBuffer == null || mKeyboardChanged) { ...
But when I compile it I get an error:
cannot find symbol
[javac] symbol : variable mBuffer
[javac] location: class
com.tabcomputing.android.zenboard.PhoneticKeyboardView
[javac] if (mBuffer == null || mKeyboardChanged) {
[javac] ^
Which I don't understand b/c mBuffer is defined in KeyboardView. What am I
doing wrong. Surely I do not have to redefine every class variable of the
superclass?
