PARSE JSON（编码基础64）Android中的STRING

Question

**$sql = 'select * from dish_category';
$results =$conn->query($sql);
$spots = array();  //array to parse jason from
while($spot = $results->fetch_assoc()){
     $spots[] = $spot;                                                           
    }

    foreach($spots as $key=>$value){
    $newArrData[$key] =  $spots[$key];
    $newArrData[$key]['Cat_Image'] = base64_encode($spots[$key]['Cat_Image']);
}
header('Content-type: application/json');
echo json_encode($newArrData);**

上面是PHP代码，它工作得很好并返回JSON字符串，现在我很困惑如何解析android中的图像（解码base64）？

Answer 1

你应该逐一做到：

• Get the JSON response as string in android.
• Parse the JSON and get the base64 string only.
• Convert the base64 string to byte array by decoding it.
• Create a new ByteArrayInputStream using the byte array.
• 使用输入流创建位图：BitmapFactory.decodeStream(inputStream)

Answer 2

 byte[] decodedString = Base64.decode(encodedImage, Base64.DEFAULT);
 Bitmap decodedByte = BitmapFactory.decodeByteArray(decodedString, 0, 
 decodedString.length);
