示例1: registerListener
import android.view.ViewTreeObserver; //導入方法依賴的package包/類
private void registerListener(View anchor) {
// Don't do anything if we haven't managed to patch the super listener.
// And don't bother attaching the listener if the anchor view isn't
// attached. This means we'll only have to deal with the real VTO owned
// by the ViewRoot.
if (mSuperScrollListener != null) {
ViewTreeObserver vto = (anchor.getWindowToken() != null) ? anchor.getViewTreeObserver()
: null;
if (vto != mViewTreeObserver) {
if (mViewTreeObserver != null && mViewTreeObserver.isAlive()) {
mViewTreeObserver.removeOnScrollChangedListener(mSuperScrollListener);
}
if ((mViewTreeObserver = vto) != null) {
vto.addOnScrollChangedListener(mSuperScrollListener);
}
}
}
}
