如何用颜色填充android中行之间的区域？

有一段代码可以创建两条从左侧延伸到顶部的曲线。考虑到线条可以移动的事实，如何用正确的颜色填充它们之间形成的区域？

public class DrawView extends View {

Paint paint;
Path path1 = new Path();
Path path2 = new Path();

public DrawView(Context context) {
    super(context);
    init();
}

public DrawView(Context context, AttributeSet attrs) {
    super(context, attrs);
    init();
}

public DrawView(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
    init();
}

private void init() {
    paint = new Paint();
    paint.setStyle(Paint.Style.STROKE);
}

@Override
protected void onDraw(Canvas canvas) {
    super.onDraw(canvas);
    path1.reset();
    path2.reset();

    paint.setColor(Color.RED);
    paint.setStrokeWidth(3);

    path1.moveTo(0, 750);
    path2.moveTo(0, 900);

    path1.cubicTo(185, 250, 599, 177, 585, 0);
    path2.cubicTo(350, 250, 750, 177, 900, 0);

    canvas.drawPath(path1, paint);
    canvas.drawPath(path2, paint);

 }
}
