如何在Android中获取屏幕的中心坐标? [英] How to get the center coordinates of the screen in android?

问题描述

我正在尝试获取屏幕中心的x和y坐标.这是我尝试过的:

I am trying to get the x and y coordinates of the center of the screen. Here is what i tried:

Display display = getWindowManager().getDefaultDisplay();
final Point size = new Point();
display.getSize(size);
height = size.y;
float centerY=height/2;//i expect this is the y coordinate of center

但是当我说:这不起作用

But this does not work, when i say:

SomeImageView.setY(centerY);

我在屏幕中央看不到它.有人可以帮我吗?

I do not see it at the center of the screen. Can anyone help me with this?

谢谢

推荐答案

我想您已经正确获取了中心坐标，但是 setY 设置了底部边缘的位置ImageView .在我头顶上方，您可以尝试类似

I guess you're correctly getting the center coordinates, but setY is setting the position of the bottom edge of your ImageView. Off the top of my head, you may try something like

SomeImageView.setY(height - SomeImageView.getDrawable().getIntrinsicHeight());
