问题描述

我是android studio的新手，我想在android studio中显示来自SQL serverimage数据类型的图像。我的网站已经在生产中运行，并且在asp.net中工作正常，因此转换其他数据类型的图像是不可行的，因为它需要大量测试。请帮助。

推荐答案

图像以字节数组的形式发送。你可以使用从sql server到你的android应用程序的RestFUll api来访问它们。

图像将在json中检索，然后从bytes数组转换为图像。

Images are sent in the form of bytes array. you can access them by using a RestFUll api from sql server to your android application.
image will be retrieved in json and then converted to image from bytes array.

JSONArray jsonArray = new JSONArray(jsonString);
for (int i = 0; i < jsonArray.length(); i++) {
    JSONObject jsonObject = (JSONObject) jsonArray.get(i);


    byte[] byteArray =  Base64.decode(jsonObject.getString("image"), Base64.DEFAULT) ;
    Bitmap bmp1 = BitmapFactory.decodeByteArray(byteArray, 0, byteArray.length);

   
}

bmp1是图片，您可以根据需要使用

bmp1 is the image, you can use it according to your needs
