在 Android 中解析 JSON（编码 base 64）字符串

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);**

以上是 PHP 代码，它运行良好并返回 JSON 字符串，现在我很困惑如何在 android 中解析图像（解码 base64）？

Answer 1

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

Answer 2

你应该一个一个地做：

• 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)
