如何获得从视图到手机底部的距离? [英] How to get distance from the View to a phone bottom?

问题描述

如果我在布局上有某个视图(例如ImageView)，是否可以找到从视图底部边框到电话屏幕底部的距离?

If I have a certain View on the layout (ImageView, for example), is it possible to find the distance from the bottom border of the View to the bottom of the phone screen?

谢谢.

推荐答案

// instantiate DisplayMetrics
DisplayMetrics dm = new DisplayMetrics(); 
// fill dm with data from current display        
getActivity().getWindowManager().getDefaultDisplay().getMetrics(dm);
// loc will hold the coordinates of your view
int[] loc = new int[2];
// fill loc with the coordinates of your view (loc[0] = x, looc[1] = y)
yourImageView.getLocationOnScreen(loc);
// calculate the distance from the TOP(its y-coordinate) of your view to the bottom of the screen
int distance = dm.heightPixels - loc[1];
