如何从Android imageview获取图像并存储到db中

Question

如何从android图像视图获取图像以及如何将该值存储到数据库中？

Answer 1

you first get drawble from imageview

Drawable d = yourimageview.getDrawable();

and then convert into byte array to store into database

BitmapDrawable bitmapDrawable = ((BitmapDrawable) drawable);
Bitmap bmp = bitmapDrawable .getBitmap();
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(bmp.CompressFormat.JPEG, 100, stream);
byte[] arr = stream.toByteArray();

now you can easily store byte array ie arr into database as blob.
