判断listview是否已经滑动到底部

lv.setOnScrollListener(new AbsListView.OnScrollListener() {
@Override
public void onScrollStateChanged(AbsListView view, int scrollState) {

}
@Override
public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {
if ((firstVisibleItem + visibleItemCount) == totalItemCount) {
View lastVisibleItemView = lv.getChildAt(lv.getChildCount() - 1);
if (lastVisibleItemView != null && lastVisibleItemView.getBottom() == lv.getHeight()) {
Toast.makeText(BaseActivity.this,"到达底部",Toast.LENGTH_SHORT).show();

}
}
}
});
