dynamically adding two views one below other

I want to add two views one after the other, I used this way but I am getting an error. This is my XML.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"

 >
<ScrollView 
 android:layout_width="fill_parent"
android:layout_height="fill_parent"

>
        <RelativeLayout 
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:id="@+id/parent"


      >

              <RelativeLayout 
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:id="@+id/rel1"
                android:layout_alignParentTop="true"

              ></RelativeLayout>

                <RelativeLayout 
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:id="@+id/rel2"
                android:layout_below="@+id/rel1"                  
              ></RelativeLayout>

      </RelativeLayout>
   </ScrollView>
</RelativeLayout>

In the two Relative layouts rel1,and rel2 I will add my custom views which are going to be drawn dynamically.

my code:

setContentView(R.layout.main);
        RelativeLayout rlstat1=(RelativeLayout)findViewById(R.id.rel1);
        RelativeLayout rlstat2=(RelativeLayout)findViewById(R.id.rel2);
        RelativeLayout.LayoutParams para1 = new       RelativeLayout.LayoutParams(
                viewWidth, viewHeight);
         RelativeLayout.LayoutParams para2 = new       RelativeLayout.LayoutParams(
                viewWidth, viewHeight);

        rlstat1.setLayoutParams(para1);
        rlstat1.addView(mView);

        para2.addRule(RelativeLayout.BELOW, R.id.rel1);
        rlstat2.addView(mView2);

Here mView and mView2 are two view type which I want to set in the two relative layouts. ViewWidth and ViewHeight are the width and height of the screen it is running.

The problem: If only one view is added i.e. mView or mView2 it's showing but if both the views are added(like in above) then only one relative layout is shown. I want that both of my views get set one below other.
Hope I am clear in my question.Can you please tell me the appropriate way to do this.

you are setting layout params to views dynamically in activity and these are new layout params objects, so your rule to add rel2 to below of rel1 gets cleared, instead try:

setContentView(R.layout.main);
        RelativeLayout rlstat1=(RelativeLayout)findViewById(R.id.rel1);
        RelativeLayout rlstat2=(RelativeLayout)findViewById(R.id.rel2);
        RelativeLayout.LayoutParams para1 = rlStat1.getLayoutParams();

        para1.width=LayoutParams.FILL_PARENT;
        para1.height=LayoutParams.FILL_PARENT;
         RelativeLayout.LayoutParams para2 = rlStat2.getLayoutParams();

        para2.width=LayoutParams.FILL_PARENT;
        para2.height=LayoutParams.FILL_PARENT;
        rlstat1.setLayoutParams(para1);
        rlstat1.addView(mView);

        para2.addRule(RelativeLayout.BELOW, R.id.rel1);
        rlstat2.addView(mView2);
