読み込む画像の大きさに合わせてImageViewの大きさを拡大する方法。バナーを画面幅いっぱいに拡大して、その高さに合わせてImageViewの高さを調整したい場合に使えます。(Android 4.4からは scaleType="centerCrop" adjustViewBounds="true" とするだけで良いのですが)

	ImageView view = new ImageView(context) {
	final RectF r = new RectF();

	@Override
	protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
	Drawable d = getDrawable();
	if (d != null) {
	r.set(0, 0, d.getIntrinsicWidth(), d.getIntrinsicHeight());
	getImageMatrix().mapRect(r);
	setMeasuredDimension((int) r.width(), (int) r.height());
