Taking a "screenshot" of a specific layout in Android

I have two main issues which are closely linked. I am looking at these problems from a programmatic point of view.

(1) - I wish to take a screenshot of the contents of a SPECIFIC layout, i.e. a ScrollView nested in a LinearLayout.

(2) - As the ScrollView has content that spills out of the screen (hence scrolling made possible), how can I ensure that the screenshot includes the elements that are not visible on the screen?

This is the current block of code I use. It does the job of taking a screenshot but only for the entire screen. This is even though R.id.boss is the ID of the ScrollView and not the main LinearLayout.

View view = findViewById(R.id.boss);
View v = view.getRootView();// this does not seem to make a difference
v.setDrawingCacheEnabled(true);                                                
v.measure(MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED), 
MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
v.layout(0, 0, v.getMeasuredWidth(), v.getMeasuredHeight());    
v.buildDrawingCache(true);
Bitmap b = Bitmap.createBitmap(u.getDrawingCache());             
v.setDrawingCacheEnabled(false);

Thanks in advance.

EDIT:

I've made a few mistakes. I used R.id.boss which is the wrong resource. I am now able to take a screenshot of the scrollview alone, less the out-of-screen parts.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/boss"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_gravity="top"
android:orientation="vertical" >

    <TextView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="F"
    android:textAppearance="?android:attr/textA
