i test the RIchPathView inside the ZoomLayout
please modify the code in RichPathView:

@OverRide
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {

    //if (vector == null) return;

    int desiredWidth = (int) (vector == null ? 0 : vector.getWidth());
    int desiredHeight = (int) (vector == null ? 0 : vector.getHeight());
