Android: How to change CheckBox size?

I found a way to do it without creating your own images. In other words, the system image is being scaled. I don't pretend that the solution is perfect; if anyone knows a way to shorten some of the steps, I'll be happy to find out how.

First, I put the following in the main activity class of the project (WonActivity) . This was taken directly from Stack Overflow -- thank you guys!

/** get the default drawable for the check box */
Drawable getDefaultCheckBoxDrawable()
{
  int resID = 0;

  if (Build.VERSION.SDK_INT <= 10)
  {
    // pre-Honeycomb has a different way of setting the CheckBox button drawable
    resID = Resources.getSystem().getIdentifier("btn_check", "drawable", "android");
  }
  else
  {
    // starting with Honeycomb, retrieve the theme-based indicator as CheckBox button drawable
    TypedValue value = new TypedValue();
    getApplicationContext().getTheme().resolveAttribute(android.R.attr.listChoiceIndicatorMultiple, value, true);
    resID = value.resourceId;
  }

  return getResources().getDrawable(resID);
}

Second, I created a class to "scale a drawable". Please notice that it is completely different from the standard ScaleDrawable.

import android.graphics.drawable.*;

/** The drawable that scales the contained drawable */

public class ScalingDrawable extends LayerDrawable
{
  /** X scale */
  float scaleX;

  /** Y scale */
  float scaleY;

  ScalingDrawable(Drawable d, float scaleX, float scaleY)
  {
    super(new Drawable[] { d });
    setScale(scaleX, scaleY);
  }

  ScalingDrawable(Drawable d, float scale)
  {
    this(d, scale, scale);
  }

  /** set the scales */
  void setScale(float scaleX, float scaleY)
  {
    this.scaleX = scaleX;
    this.scaleY = scaleY;
  }

  /** set the scale -- proportional scaling */
  void setScale(float scale)
  {
    setScale(scale, scale);
  }

  // The following is what I wrote this for!

  @Override
  public int getIntri
