Here i want to set the layoutMarginBottom of the scrollview.Please help me.Thanks in advance.

Do you want to just set the layoutMarginBottom of scrollview through activity class? — Jivan, Sep 23 '12 at 06:27
You may need to set margins through linearlayout adding into scrollview. — Jivan, Sep 23 '12 at 06:57
you should edit this question instead of asking multiple same question... http://stackoverflow.com/questions/12550325/getting-exception-while-setting-layoutparams-of-scrollview-programmatically — nKandel, Sep 23 '12 at 07:28

I made it done in this way:

sv = (ScrollView)findViewById(R.id.scrollView);
sv.setBackgroundColor(Color.TRANSPARENT);

RelativeLayout.LayoutParams layoutParams = (RelativeLayout.LayoutParams) sv
    .getLayoutParams();

layoutParams.setMargins(0, 0, 0, 100);
sv.setLayoutParams(layoutParams);

Why are you setting bottomMargin twice? – Jivan Sep 23 '12 at 07:18
yes @Zane is right delete this line layoutParams.bottomMargin = 100; or this line layoutParams.setMargins(0, 0, 0, 100); and your answers is gonna be absolutely correct. – Stoycho Andreev Jul 06 '16 at 23:15

In case if you are getting

java.lang.ClassCastException: android.widget.FrameLayout$LayoutParams cannot be cast to android.widget.RelativeLayout$LayoutParams

with above solution then try:

 ScrollView sv = (ScrollView)findViewById(R.id.scrollView);    
 FrameLayout.LayoutParams lp = (FrameLayout.LayoutParams)sv.getLayoutParams();

 lp.bottomMargin = 100;
 sv.setLayoutParams(lp);

I got this error:

Blockquote java.lang.ClassCastException: androidx.coordinatorlayout.widget.CoordinatorLayout$LayoutParams cannot be cast to ...

then as I want to change Top Margin for NestedScrollView I try the above solution with some modifications:

CoordinatorLayout.LayoutParams layoutParams = (CoordinatorLayout.LayoutParams) nestedScrollView.getLayoutParams();

layoutParams.topMargin = 56;

nestedScrollView.setLayoutParams(layoutParams);
