Use below code. It may helps you -
使用下面的代码。它可能会帮助你——
public static Bitmap getRoundedCornerBitmap(Bitmap bitmap) {
Bitmap output = Bitmap.createBitmap(bitmap.getWidth(),
bitmap.getHeight(), Config.ARGB_8888);
Canvas canvas = new Canvas(output);
final int color = 0xff424242;
final Paint paint = new Paint();
final Rect rect = new Rect(0, 0, bitmap.getWidth(), bitmap.getHeight());
final RectF rectF = new RectF(rect);
final float roundPx = 12;
paint.setAntiAlias(true);
canvas.drawARGB(0, 0, 0, 0);
paint.setColor(color);
canvas.drawRoundRect(rectF, roundPx, roundPx, paint);
paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
canvas.drawBitmap(bitmap, rect, rect, paint);
return output;
}
Pass your Bitmap image into this method and get that as rounded corner.
将您的位图图像传递到此方法中并将其作为圆角。

What if you try to set a background to your ImageView, defining a Shape in xml that would only contain a "corner" Attribute? Something like that:
如果您尝试为 ImageView 设置背景，在 xml 中定义一个只包含“角”属性的 Shape，该怎么办？类似的东西：
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<corners android:radius="20dip" />
</shape>
