获取视图边距 [英] Get margin of a View

问题描述

如何从活动"中获取视图的边距值?视图可以是任何类型.

How can I get the margin value of a View from an Activity? The View can be of any type.

经过一些搜索，我找到了获取视图填充的方法，但是在Margin上找不到任何内容.有人可以帮忙吗?

After a bit of searching I found out ways to get padding of a view, but couldn't find anything on Margin. Can anyone help?

我尝试过类似的事情

ViewGroup.LayoutParams vlp = view.getLayoutParams();
int marginBottom = ((LinearLayout.LayoutParams) vlp).bottomMargin;

这有效，但是在上面的代码中，我假定视图为LinearLayout.但是，即使我不知道视图类型，也需要获取margin属性.

This works, but in the above code I have assumed the view to be a LinearLayout. But I need to get the margin attribute even when I don't know the view type.

推荐答案

尝试一下:

View view = findViewById(...) //or however you need it
LayoutParams lp = (LayoutParams) view.getLayoutParams();

边距可通过

lp.leftMargin;
lp.rightMargin;
lp.topMargin;
lp.bottomMargin;

修改: 也许ViewGroup.MarginLayoutParams将为您工作.这是其他LayoutParams的基类.

edit: perhaps ViewGroup.MarginLayoutParams will work for you. It's a base class for other LayoutParams.

ViewGroup.MarginLayoutParams lp = (ViewGroup.MarginLayoutParams) view.getLayoutParams();
