Rails 3，国际化（I18n） - 将数字转换为值(Rails 3, Internationalization (I18n) - Translate number to value)

 好的，我找到了一个很好的解决方案：OnScrollListener提供了我所需要的一切，而这里不需要OnGlobalLayoutListener。 
 
public class ArrayListAdapter extends ArrayAdapter<String>
    implements AbsListView.OnScrollListener

...

@Override
public void onScrollStateChanged(AbsListView view, int scrollState) {}

@Override
public synchronized void onScroll(final AbsListView listView, int firstVisibleItem,
                                  int visibleItemCount, int totalItemCount) {
    List<Integer>yList = new ArrayList<>();
    int checkedPosition = listView.getCheckedItemPosition();
    double yChecked = 0;

    for (int pos = 0; pos < totalItemCount; pos++) {
        CheckedTextView tv = (CheckedTextView) this
                .getViewByPosition(pos, listView, firstVisibleItem,
                        firstVisibleItem + visibleItemCount - 1);
        if (pos == checkedPosition) {
            yChecked = tv.getY();
        }
        yList.add(pos, tv.getY());
    }        
    // Here I pass the fresh y-values to the fragment holding the 
    // two ListViews. After some further calculations the fragment
    // passes the data to the TextView where it is stored and
    // this.invalidate is called to eventually trigger the onDraw method.
    originalFragment.setScrollData(yList, yChecked);
}

private View getViewByPosition(int pos, AbsListView listView, int firstVisibleItem,
                               int lastVisibleItem) {
    if (pos < firstVisibleItem || pos > lastVisibleItem) {
        // The next line is the only downside of this solution I have
        // found so far. If the convertView of the getView(int
        // position, View convertView, ViewGroup parent) method is null
        // the holder pattern I applied in my adapter becomes useless.
        // In my case the recreation of the CheckedTextViews is fast
        // enough though.
        return listView.getAdapter().getView(pos, null, listView);
    } else {
        return listView.getChildAt(pos - firstVisibleItem);
    }
}

Okay, I found a good solution: the OnScrollListener provides all I need, while the OnGlobalLayoutListener is not needed here.
 
public class ArrayListAdapter extends ArrayAdapter<String>
    implements AbsListView.OnScrollListener

...

@Override
public void onScrollStateChanged(AbsListView view, int scrollState) {}

@Override
public synchronized void onScroll(final AbsListView listView, int firstVisibleItem,
                                  int visibleItemCount, int totalItemCount) {
    List<Integer>yList = new ArrayList<>();
    int checkedPosition = listView.getCheckedItemPosition();
    double yChecked = 0;

    for (int pos = 0; pos < totalItemCount; pos++) {
        CheckedTextView tv = (CheckedTextView) this
                .getViewByPosition(pos, listView, firstVisibleItem,
                        firstVisibleItem + visibleItemCount - 1);
        if (pos == checkedPosition) {
            yChecked = tv.getY();
        }
        yList.add(pos, tv.getY());
    }        
    // Here I pass the fresh y-values to the fragment holding the 
    // two ListViews. After some further calculations the fragment
    // passes the data to the TextView where it is stored and
    // this.invalidate is called to eventually trigger the onDraw method.
    originalFragment.setScrollData(yList, yChecked);
}

private View getViewByPosition(int pos, AbsListView listView, int firstVisibleItem,
                               int lastVisibleItem) {
    if (pos < firstVisibleItem || pos > lastVisibleItem) {
        // The next line is the only downside of this solution I have
        // found so far. If the convertView of the getView(int
        // position, View convertView, ViewGroup parent) method is null
        // the holder pattern I applied in my adapter becomes useless.
        // In my case the recreation of the CheckedTextViews is fast
        // enough though.
        return listView.getAdapter().getView(pos, null, listView);
    } else {
        return listView.getChildAt(pos - firstVisibleItem);
    }
}
