怎么让imageview变成圆形

Answer 1

方法咐穗：public static Bitmap toOvalBitmap(Bitmap bitmap, float pix) {
try {
Bitmap output = Bitmap.createBitmap(bitmap.getHeight(),
bitmap.getWidth(), Config.ARGB_8888);
Canvas canvas = new Canvas(output);
Paint paint = new Paint();
Rect rect = new Rect(0, 0, bitmap.getWidth(), bitmap.getWidth());
RectF rectF = new RectF(rect);
float roundPx = pix;
paint.setAntiAlias(true);
canvas.drawARGB(0, 0, 0, 0);
int color = 0xff424242;
paint.setColor(color);
canvas.drawOval(rectF, paint);
canvas.drawRoundRect(rectF, roundPx, roundPx, paint);
paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
canvas.drawBitmap(bitmap, rect, rect, paint);
return output;
} catch (Exception e) {
/迅正/ TODO: handle exception
return null;
}
}
