Question

我试图通过将Android应用程序中的图像转换为Base64来在PHP应用程序上显示Base64图像。它无法在我的浏览器上显示，但它在Android应用程序中很好。

我的Java代码

imgChild.buildDrawingCache();
Bitmap bmap = imgChild.getDrawingCache();
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bmap.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] byteFormat = stream.toByteArray();
String imgString = Base64.encodeToString(byteFormat, Base64.NO_WRAP);

这是从上面的代码

获得的Base64字符串

我尝试使用

以HTML格式显示

<img src="data:image/png;base64,iVBORw0KGgoAAA....." />

如何解决这个问题？

感谢。

Answer 1

您的代码似乎正确，请尝试将BASE64格式替换为：

String imgString = Base64.encodeToString(byteFormat, Base64.DEFAULT);

如果仍无效，请查看此answer

希望这有帮助！
