[android-developers] onDraw canvas within a ScrollView?

How can I construct this scenario?

I want to build a game where the game board is a canvas controlled by
a custom View but within a ScrollView. The game board is potentially
much bigger than the screen and I want to scale, scroll around the
game. However, I want all the advantages of the UI outside the game
board to include Buttons, TextViews, ImageViews, etc.

Here's the outline code of what I imagine should work. Am I wrong in
thinking I can use both
my own onDraw and expect buttons and other widgets to be managed by
Android? Must I implement
all my own UI ?

Just trying to deal with a Button (see below) fails me

Here's the XML where I want my custom view surrounded by other UI
elements
------------------------------
// game.xml <snippet>
<ScrollView
android:layout_width="240dp"
android:layout_height="600dp"

<com.android.example.game.DrawBoardView
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</ScrollView>
<TextView
android:id="@+id/sometext
android:layout_width="120dp"
android:layout_height= "wrap_content"
android:layout_weight="1"
android:visibility="gone"/>
<Button
android:id="@+id/editname"
android:text="DoIt"
android:layout_height="wrap_content"
android:layout_width="wrap_content">
</Button>

My main activity
----------------------
// Activity
public class gameStartActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

setContentView(R.layout.game);
}
}

// gameView.java
public class gameView extends View {

public gameView(Context context) {
super(context);
setFocusable(true); //necessary for getting the touch events
InitBoardView();
}

private void InitBoardView(){
Button myButton = (Button)findViewById(R.id.editname);

-----> fails at this point as myButton is null
myButton.setOnClickListener(doSomething);
}
@Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
canvas.drawBitmap(face, getPaddingLeft(), getPaddingTop(),paint);
}

@Override
protected void onMeasure(int widthMeasureSpec,int heightMeasureSpec)
{
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
final int widthMode = MeasureSpec.getMode(widthMeasureSpec);
final int heightMode = MeasureSpec.getMode(heightMeasureSpec);
setMeasuredDimension(xSize, ySize);

}
}
