How to know if the last row of the ListView is displayed fully?

I know how to check if the last row of the ListView is visible. However, being visible doesn't guarantee that the row is displayed fully. How can I check if the last row is displayed fully?

The solution is to compare the height of the ListView to the bottom position of the footer.

public void onScroll(AbsListView arg0, int arg1, int arg2, int arg3)
{
    if(arg1 + arg2 == arg3) //If last row is visible. In this case, the last row is the footer.
    {
        if(footer != null) //footer is a variable referencing the footer view of the ListView. You need to initialize this onCreate
        {
            if(listView.getHeight() == footer.getBottom()) //Check if the whole footer is visible.
                doThisMethod();
        }
    }
}

For the interest of others, the footer is basically a View which I added to the ListView via the addFooterView. R.layout.footer is the layout for the footer. Below is a sample code on how I initialize the footer and added it on the ListView:

View footer; //This is a global variable.
....
//Inside onCreate or any method where you initialize your layouts
footer = getLayoutInflater().inflate(R.layout.footer, null);
listView.addFooterView(footer);

I'd try something like (not tested):

if (listView.getScrollY() == listView.getMaxScrollAmount()) {
    // ...
}
