Use this method:
public byte[] convertImageViewToByteArray(ImageView image){
Bitmap bitmap = ((BitmapDrawable)image.getDrawable()).getBitmap();
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);
return stream.toByteArray();
}
Note: The method assumes that the image was assigned to Imageview with android:src.
If it was with android:background instead of
image.getDrawable()
use
image.getBackground()

In case I’m taking an image of the device and setting in Imageview, the process will be the same?

What do you mean? Explain it better.

I have an Imageview and when I click on it I take an image from the device’s gallery and press it from there by clicking on the save button it sends to the database

I still don’t understand. If you want to convert the image that is in Imageview to Byte[] use the answer method. If you have another question create a new one with the necessary details .
