java - 将 Base 64 图像解码为位图 Android

Question

我有这张来自服务器的 base64 图像

我正在测试在位图中显示图像，

byte [] byteArray = android.util.Base64.decode(input, android.util.Base64.DEFAULT);
Bitmap bitmap = BitmapFactory.decodeByteArray(byteArray, 0, byteArray.length);

但位图总是为空，知道吗？谢谢

您的 Base64 字符序列中有换行符。尝试摆脱它们。我说的是这个：\r\n。试试这个：（因为我不知道你是如何格式化字符串的）：

input = input.replace("\r\n", "").replace("\\r\\n", "");
