Code example for PointF

 
 
	private void move() { 
		scaleInc = (targetScale - startScale) / duration;
		final PointF frictionAcc = new PointF(transInc.x, transInc.y);
		frictionAcc.x *= -friction/transInc.length()/2;
		frictionAcc.y *= -friction/transInc.length()/2;
		if(friction != 0) {
			motionEndTime = motionStartTime + (long)(transInc.length() / friction);
		} 
 
		mHandler.post(new Runnable() { 
				public void run() { 
					long t = System.currentTimeMillis();
					if(t > motionEndTime)
						t = motionEndTime;
					 
					long spent = t - motionStartTime;
 
					double phase = Math.PI * spent / (motionEndTime - motionStartTime) ;
