Get margin of a View

Question

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

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?

I tried something like this,

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

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.

try this:

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

margins are accessible via

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

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

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

Actually I was expecting something like this, but I don't think there is any direct class called `LayoutParams`. There are classes like `FrameLayout.LayoutParams`, `RelativeLayout.LayoutParams`, but nothing like `LayoutParams` in itself. And since I don't know the type of the view, I cannot use any of the former classes. – Arnab Chakraborty Sep 19 '11 at 08:54

what about `ViewGroup.MarginLayoutParams lp = (ViewGroup.MarginLayoutParams) view.getLayoutParams();` then? – Vladimir Sep 19 '11 at 09:23
Should be ViewGroup.MarginLayoutParams lp = (ViewGroup.MarginLayoutParams) view.getLayoutParams(); – rockhammer Oct 12 '16 at 16:27

Try

ViewGroup.MarginLayoutParams vlp = (MarginLayoutParams) view.getLayoutParams()

vlp.rightMargin
vlp.bottomMargin
vlp.leftMargin
vlp.topMargin

This returned the correct margains for my view atleast.

The methods you mentioned give the left, right, top and bottom positions of the view, I need the margins. – Arnab Chakraborty Sep 19 '11 at 08:57
Not necessarily. A view maybe placed in a `LinearLayout` with `horizontal` orientation. If its the second view in the layout the `view.getLeft()` method would give me the the coordinate of its left but the left margin of the view from its adjacent view. – Arnab Chakraborty Sep 19 '11 at 09:04
What if the View is a `LinearLayout`? – Arnab Chakraborty Sep 19 '11 at 10:05

As others suggested, layout_margin# is the space between the parent's # edge and your view.

# replaces "Left", "Right", "Top" or "Bottom"

Getting/setting margins worked for me with:

ViewGroup.MarginLayoutParams params = (ViewGroup.MarginLayoutParams) mView.getLayoutParams();
params.topMargin += 20;
mView.requestLayout();

Of course, my View was indeed a ViewGroup and the parent was a ViewGroup as well. In most cases, you should cast your layout params to the parent's View class LayoutParams (in this case it's ViewGroup and RelativeLayout)
