Accessing Margins From Code

Question

I have a Button that uses a Style with the following 2 items:

<item name="android:layout_marginLeft">3dp</item>
<item name="android:layout_marginRight">3dp</item>

In my code, I need to access these values (for reading, I do not need to set them in code). How can I do this? Thanks.

Hello,​

Welcome to our Microsoft Q&A platform!

Try getting the LayoutParameters of the button, and then get the margins from the layout params. The value is in pixels, and you can use density to convert it to dp units.

Here is the sample code, you could refer to it.

   var button = FindViewById<Button>(Resource.Id.btn);  
   button.Click += Button_Click;  
     
   var layoutParams = button.LayoutParameters as Android.Widget.RelativeLayout.LayoutParams;//the LayoutParams type is decided by the button's parent layout  
   var leftMargin = ConvertToDP(layoutParams.LeftMargin);  
   var rightMargin = ConvertToDP(layoutParams.RightMargin);  
     
     
   int ConvertToDP(int pxValue)  
   {  
       var density = Resources.DisplayMetrics.Density;  
       return (int)(pxValue / density);  
   }
