Answer 1

This deletes all paddings (all sides) for your imgLinkdinUrl ImageView :

ImageView linkedInUrlImage = (ImageView) findViewById(R.id.imgLinkdinUrl);
linkedInUrlImage.setPadding(0, 0, 0, 0);

Answer 2

public void setPadding (int left, int top, int right, int bottom)

Sets the padding. The view may add on the space required to display the scrollbars, depending on the style and visibility of the scrollbars. So the values returned from getPaddingLeft(), getPaddingTop(), getPaddingRight() and getPaddingBottom() may be different from the values set in this call.

Finally

ImageView ImageViewObj = (ImageView) findViewById(R.id.imgLinkdinUrl);
ImageViewObj.setPadding(0, 0, 0, 0);
