如何制作六边形类型的图像视图

Question

您好，在此先感谢，我想制作 imageview 六边形或五边形，我参考了本教程，但我无法修改点。将六边形旋转 90 度或任何其他方式所需的任何更改也是如此。我对六边形使用了以下代码，但这段代码给了我六边形，但我想要旋转 90 度的相同输出。

public static Bitmap getRoundedCroppedBitmap(Bitmap bitmap, int radius) {
        Bitmap finalBitmap;
        if (bitmap.getWidth() != radius || bitmap.getHeight() != radius)
               finalBitmap = Bitmap.createScaledBitmap(bitmap, radius, radius,
                            false);
        else
               finalBitmap = bitmap;
        Bitmap output = Bitmap.createBitmap(finalBitmap.getWidth(),finalBitmap.getHeight(),Config.ARGB_8888);
        Canvas canvas = new Canvas(output);

        Paint paint = new Paint();
        final Rect rect = new Rect(0, 0, finalBitmap.getWidth(),
                     finalBitmap.getHeight());

        Point point1_draw = new Point(75, 0);
        Point point2_draw = new Point(0, 50);
        Point point3_draw = new Point(0, 100);
        Point point4_draw = new Point(75, 150);
        Point point5_draw = new Point(150, 100);
        Point point6_draw = new Point(150, 50);

        Path path = new Path();
        path.moveTo(point1_draw.x, point1_draw.y);
        path.lineTo(point2_draw.x, point2_draw.y);
        path.lineTo(point3_draw.x, point3_draw.y);
        path.lineTo(point4_draw.x, point4_draw.y);
        path.lineTo(point5_draw.x, point5_draw.y);
        path.lineTo(point6_draw.x, point6_draw.y);

        path.close();
        canvas.drawARGB(0, 0, 0, 0);
        paint.setColor(Color.parseColor("#BAB399"));
        canvas.drawPath(path, paint);
        paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
        canvas.drawBitmap(finalBitmap, rect, rect, paint);

        return output;
 }

希望对您有所帮助。 :)

Answer 2

您可以在绘制前将canvas旋转90度，绘制后恢复原状。

canvas.save(Canvas.MATRIX_SAVE_FLAG);
canvas.rotate(90);//or -90
//Do drawing here
//canvas.drawPath(...)
canvas.restore();

Answer 3

canvas.save();

canvas.rotate(90, 90, 90);

//绘制canvas
canvas.drawPath（路径，绘画）；

canvas.restore();
