Get margin of a View

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();

Try

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

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

This returned the correct margains for my view atleast.

http://developer.android.com/reference/android/view/ViewGroup.MarginLayoutParams.html

now use this edited code. this will help you

FrameLayout.LayoutParams lp=(FrameLayout.LayoutParams)mainLayout.getLayoutParams();

lp.leftMargin  // for left margin
lp.rightMargin   // for right margin

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)
