How to Add Divider to an Android Layout Programmatically
Create a View
1 or 2 pixels tall and width match_parent
and set the background color to whatever color you want the divider to be.
Separate the divider from the items above and below with margin
settings.
Example:
ImageView divider = new ImageView(this);
LinearLayout.LayoutParams lp =
new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
lp.setMargins(left, top, right, bottom);
divider.setLayoutParams(lp);
divider.setBackgroundColor(Color.WHITE);
