OK a better example would be:
boolean mInLayout = false;
in AdapterView, this has no get or set function so it can only be
accessed by classes in the same package such as Gallery with it's
onLayout function:
protected void onLayout(boolean changed, int l, int t, int r, int
b) {
super.onLayout(changed, l, t, r, b);
/*
* Remember that we are in layout to prevent more layout
request from
* being generated.
*/
mInLayout = true;
layout(0, false);
mInLayout = false;
}
I want to create a similar class to Gallery, but because my classes
are not in the same package i cannot access mInLayout. even though I
extend AbsSpinner and hence AdapterView,
so should mInLayout be protected? If it was i could then access it
and write a similar custom class to Gallery..
