Question

怎么判断android中ScrollView滑动到了最底部

Answer 1

1、判断是否已经滚动到顶部或底部，代码如下：

private void doOnBorderListener() {
if (contentView != null && contentView.getMeasuredHeight() <= getScrollY() + getHeight()) {
if (onBorderListener != null) {
onBorderListener.onBottom();
}
} else if (getScrollY() == 0) {
if (onBorderListener != null) {
onBorderListener.onTop();
}
}
}

滚动到顶部判断：getScrollY() == 0
滚动到底部判断
View contentView = getChildAt(0);
contentView.getMeasuredHeight() <= getScrollY() + getHeight();
