Android PathDashPathEffect: path shape does not work for straight line

I'm trying to create a custom view that draws a line with diagonal stripes pattern. It should look something like this:

I think using PathDashPathEffect should do, but when I set the shape of the path to be a direct path, the view draws nothing. If I add some segments to the path to close it, for example make it a triangle, then a view appears.

Here's my path form:

    Path pathShape = new Path();
    pathShape.moveTo(0, 10);
    pathShape.lineTo(10, 0);

      

        
        
        
      

    

The above doesn't work, the view doesn't show anything. The following works and shows triangles as a pattern on a line:

    Path pathShape = new Path();
    pathShape.moveTo(0, 0);
    pathShape.lineTo(10, 10);
    pathShape.lineTo(10, 0);

      

        
        
        
      

    

My whole custom view:

private final Paint paint;
private final Path path;

public MyView(Context context, AttributeSet attrs) {
    super(context, attrs);
    paint = new Paint();
    paint.setStyle(Paint.Style.STROKE);
    paint.setStrokeWidth(20);
    paint.setColor(Color.RED);
    Path pathShape = new Path();
    pathShape.moveTo(0, 0);
    pathShape.lineTo(10, 10);
    pathShape.lineTo(10, 0);
    PathDashPathEffect pathEffect = new PathDashPathEffect(pathShape, 30, 30, PathDashPathEffect.Style.ROTATE);
    paint.setPathEffect(pathEffect);
    path = new Path();
}

@Override
protected void onDraw(Canvas canvas) {
    path.reset();
    path.moveTo(0, getHeight() / 2);
    path.lineTo(getWidth(), getHeight() / 2);
    canvas.drawPath(path, paint);
}

      

        
        
        
      

    

Does anyone know how to achieve this?

Many thanks!
