You can do it by saving the bitmap of image in cache followed by sharing it.

//To get the bitmap from Imageview
imageView.setDrawingCacheEnabled(true);
Bitmap bitmap = imageView.getDrawingCache();

//To share it via Intent**
try {
    File file = new File(getContext().getCacheDir(), fileName + ".png");
    FileOutputStream fOut = new FileOutputStream(file);
    bitmap.compress(CompressFormat.PNG, 100, fOut);
    fOut.flush();
    fOut.close();
    file.setReadable(true, false);
    final Intent intent = new Intent(android.content.Intent.ACTION_SEND);
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file));
    intent.setType("image/png");
    startActivity(intent);
} catch (Exception e) {
    e.printStackTrace();
}
