Giving java.lang.NullPointerException at MLRoundedImageView.onDraw(MLRoundedImageView.java:56)
I added one more button, when the button was clicked, it open the gallery, let user select the picture and inflate into your CircleImageView. everything was OK.
but, somehow, Some pictures auto rotated in CircleImageView.
I'm a newbie in Android, so, Could you please help me, how do I disable the auto rotation?
Thanks.
hi ,
the code is running on my side but issue is pixels of the image are too bad how to fix it ?
Please change 27-28 lines to:
Bitmap b;
try {
b = ((BitmapDrawable) drawable).getBitmap();
} catch (ClassCastException e) {
Log.e(TAG, String.format("You can't use %s!", drawable.getClass().getSimpleName()), e);
return;
}
Bitmap bitmap = b.copy(Bitmap.Config.ARGB_8888, true);`
for cases if somebody trying to use LayerDrawable, for example.
Nice solution.. how can i create border for this rounded image view??
Many thanks <3
Scale Type 😭
thanks @Megamzero . It worked for me. (Y)
Thanks! Worked for me
how to add source image in this?
for those who wants a center crop
create a Rect like this
and draw the bitmap like this
canvas.drawBitmap(sbmp, rectSrc, rect, paint);
