1. RotateAnimation, pivoting about the center

ok, i found it.

animation stuff works OK: it rotates tho whole view (not image
bounds), run hierarchyviewer and
you'll see that pivot is ok.

if you try to rotate image itself, try this

ImageView iv = (ImageView) findViewById(R.id.iv);
Matrix matrix = iv.getImageMatrix();
RectF dst = new RectF();
matrix.mapRect(dst, new RectF(iv.getDrawable().getBounds()));
Log.d("Test", "Dst " + dst);
RotateAnimation a = new RotateAnimation(0, 360, iv.getPaddingLeft() +
dst.centerX(), iv.getPaddingTop() + dst.centerY());


2. totally confused about how to change the layout of a button at runtime


You have to use the LayoutParams that correspond the your Button's
parent. In this case, you need to use LinearLayout.LayoutParams.
