Java 如何解码Base64中编码的png图像并在ImageView上查看？

我的android设备向服务器请求png图像。服务器用Base64编码图像并将其发送到我的设备。之后，我将Base64字符串解码为字节数组，并使用BitmapFactory.decodeByteArray（）为其生成位图图像。在ImageView中添加图像时，我看不到该图像

请参见下面的代码：

JSONObject params = resultObject.getJSONObject("params");
byte[] decodedImageInBytes = Base64.decode(params.getString("image_one"), Base64.DEFAULT);

Bitmap myImage = BitmapFactory.decodeByteArray(decodedImageInBytes, 0, decodedImageInBytes.length);
ImageView imageViewOne = (ImageView) findViewById(R.id.imageViewOne);
imageViewOne.setImageBitmap(myImage);

编辑：

JSONObject params = resultObject.getJSONObject("params");
byte[] decodedImageInBytes = Base64.decode(params.getString("image_one"), Base64.DEFAULT);

Bitmap myImage = BitmapFactory.decodeByteArray(decodedImageInBytes, 0, decodedImageInBytes.length);
ImageView imageViewOne = (ImageView) findViewById(R.id.imageViewOne);
imageViewOne.setImageBitmap(myImage);

看来我的代码还可以，我的服务器有一些问题。谢谢大家

我已经为您解码了您的字符串。它不是位图数据

params.getString（“image_one”）的示例，请？这是base64中编码图像的字符串。我理解。您可以发布这样一个base64字符串的示例吗？解码后是否有有效的高度和宽度位图？我解码base64图像与您完全一样，没有任何问题。同意@Renard。您的代码看起来很好（根据和）所以我猜数据已经损坏或者不是预期的格式。是的，我也看到了。：D谢谢你的帮助！
