如何在canvas android中绘制弯曲箭头

public class CurvedArrowView extends View {
    private Paint paint;

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

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

    public CurvedArrowView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        init();
    }

    private void init() {
        paint = new Paint();
        paint.setColor(Color.BLACK);
        paint.setStrokeWidth(5);
        paint.setStyle(Paint.Style.STROKE);
    }

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

        int width = getWidth();
        int height = getHeight();

        Path path = new Path();
        path.moveTo(width / 4, height / 2);
        path.quadTo(width / 2, height / 4, width * 3 / 4, height / 2);
        path.lineTo(width * 3 / 4 - 20, height / 2 - 10);
        path.lineTo(width * 3 / 4, height / 2);
        path.lineTo(width * 3 / 4 - 20, height / 2 + 10);
        path.close();

        canvas.drawPath(path, paint);
    }
}

<com.example.myapplication.CurvedArrowView
    android:layout_width="match_parent"
    android:layout_height="match_parent" />
