but better idea is what Kostya suggested: custom ViewGroup, like this:
public class ILayout extends FrameLayout {
private Button mButton;
private ImageView mImageView;
public ILayout(Context context, AttributeSet attrs) {
super(context, attrs);
mImageView = new ImageView(context);
mImageView.setImageResource(R.drawable.test);
addView(mImageView);
mButton = new Button(context);
addView(mButton);
}
@Override
protected void onLayout(boolean changed, int left, int top, int
right, int bottom) {
super.onLayout(changed, left, top, right, bottom);
float[] pts = {
1, 1, 4, 4
};
mImageView.getImageMatrix().mapPoints(pts);
mButton.layout((int) pts[0], (int) pts[1], (int) pts[2], (int)
pts[3]);
}
}
here we have an ImageView displaying 5x5 test.png image and a button
which should appear scaled and translated in the centre of ImageView's
image
