Android subpixel rendering

Question

I have a line that should get thinner the longer it gets. The problem is, that you can clearly see a jump when it gets a pixel thinner. Is there a way to do subpixel rendering/a

Answer 1

This seems to do a better job:

@Override
protected void onDraw(Canvas canvas) {
    float width = getMeasuredWidth() / (float) getMeasuredHeight()  * getMinimumHeight();
    float left = (getMeasuredWidth() - width) / 2.0f;
    paint.setStrokeWidth(width * getResources().getDisplayMetrics().density);
    canvas.drawLine(left, 0, left, getMeasuredHeight(), paint);
    super.onDraw(canvas);
}
