检测PopupWindow是否通过ScrollView

ScrollView scrollView = findViewById(R.id.scrollView); // 获取ScrollView实例
View popupView = getLayoutInflater().inflate(R.layout.popup_layout, null); // 获取PopupWindow的内容视图

PopupWindow popupWindow = new PopupWindow(popupView, ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
popupWindow.setOutsideTouchable(true); // 设置点击外部区域可以关闭PopupWindow

// 在PopupWindow显示之前获取ScrollView的高度和PopupWindow的高度
int scrollViewHeight = scrollView.getHeight();
int popupWindowHeight = popupView.getHeight();

// 在PopupWindow显示之后获取ScrollView的滚动位置和PopupWindow的位置
int scrollViewScrollY = scrollView.getScrollY();
int popupWindowY = popupView.getY();

// 判断PopupWindow是否完全通过ScrollView
boolean isPopupWindowPassed = (popupWindowY + popupWindowHeight) <= (scrollViewScrollY + scrollViewHeight);

if (isPopupWindowPassed) {
    // PopupWindow完全通过ScrollView
    // 进行相应的操作
} else {
    // PopupWindow未完全通过ScrollView
    // 进行相应的操作
}
