从加载的ImageView获取图像

Question

I had a problem where some of my images are loaded inside imageview rotated. I solved the problem by loading an image using Glide.

The image is loaded inside 100 x 100 imageview. Can I retrieve the image which is stored inside that imageview as 100 x 100 and upload it to the server instead of sending the original image?

Yes you can

public byte[] getImageFromImageView(ImageView imageView,String filePath) {
    Drawable imageDrawable = imageView.getDrawable();
    Bitmap imageBitmap = ((BitmapDrawable)imageDrawable).getBitmap();
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    imageBitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);
    byte[] byteArray = stream.toByteArray();
    return byteArray;
}

Then upload file to server or you can create RequestBody and send it to server if you using Retrofit.
