I have added a linearlayout in a linearlayout dynamically using this code. 

LinearLayout root = (LinearLayout) findViewById(R.id.root);
View child = inflater.inflate(R.layout.childrow, null);
root.addView(child , index++);

I want to add bottom margin in childview. Can I do this dynamically?

View child = inflater.inflate(R.layout.childrow, null);
LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT); 
layoutParams.setMargins(leftMargin, topMargin,rightMargin, bottomMargin);
child.setLayoutParams(layoutParams);
root.addView(child , index++);

    @rAviNder It probably says "NullPointerException". Sorry, I had to. – Lo-Tan Jul 23 '14 at 03:36

    Posting wrong, not tested code makes no point, sorry. Instead of: //LinearLayout.LayoutParams params = (LinearLayout.LayoutParams) child.getLayoutParams(); Add: LinearLayout.LayoutParams layParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT); – Yar Dec 09 '14 at 07:40

LayoutParams params=(LayoutParams) child.getLayoutParams();
    params.setMargins(0, 0, 0, 5);
child.setLayoutParams(params);

The params.setMargins(0, 0, 0, 5); allows to set margins for left, top, right and bottom respectively. So to set a margin to the bottom of your child view, replace 5 with a number of your choice.

Hope this will help.. :)
