Keep a reference to MyView in the activity, just like you would normally
do with:
findViewById(... buttonSomethingOrOther ... )
Add methods to MyView to do what you need.
Call those methods as necessary, just like you can call
"mButton.setEnabled(false);" or whatever.

Hello,
Using the example from the API FingerPaint as a basis, I have
something similar to the following structure:
public class FingerPaint extends GraphicsActivity
implements ColorPickerDialog.OnColorChangedListener {
[...]
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(new MyView(this));
[...]
}
The class that has been set as contentView (MyView) contains a Canvas:
public class MyView extends View {
[..]
public Canvas mCanvas;
[..]
}
How could I access this mCanvas in order to redraw it when an external
event is triggered (i.e., clicking a button from the menu). Obviously
I can access them from FingerPaint, since the attributes from MyView
are not inherited, but I can't neither access MyView directly, since
it is "absorbed" by the class FingerPrint.
Any idea, before redesigning the classes?
Thanks!
