android - Rotate Frame layout which contains dynamic buttons -
i have framelayout add 4 imageview @ runtime in center contains main image user can perform different action face problem rotate layout view
currently on touch of rotate button i'm doing this
public void setrotatelistener() { mrotateimage.setontouchlistener(new ontouchlistener() { @override public boolean ontouch(view v, motionevent event) { float x = event.getx(0); float y = event.gety(0); float theta = gettheta(x, y); switch (event.getaction() & motionevent.action_mask) { case motionevent.action_pointer_down: theta_old = theta; break; case motionevent.action_move: float delta_theta = theta - theta_old; theta_old = theta; int direction = (delta_theta > 0) ? 1 : -1; angle += 3 * direction; log.d("tag", "rotate angle : " + obj.getheight()); obj.setrotation(angle); notifylistener(direction); break; } return true; } }); } private float gettheta(float x, float y) { float sx = x - (obj.getwidth() / 2.0f); float sy = y - (obj.getheight() / 2.0f); float length = (float) math.sqrt(sx * sx + sy * sy); float nx = sx / length; float ny = sy / length; float theta = (float) math.atan2(ny, nx); final float rad2deg = (float) (180.0 / math.pi); float thetadeg = theta * rad2deg; return (thetadeg < 0) ? thetadeg + 360.0f : thetadeg; } but can't expected result refer link https://github.com/rprouse/xkcdclock try rotate gesture , animation seems not working per move on screen
i have design layout may work need. download demo here
