java获取位图图像的路径并将其转换为Base64
我试着选择一个图像的路径,比如: "content://media/external/images/media/3"
并将其转换为base64字符串
以下是我现在掌握的代码:
public String ConvertandSetImagetoBase64(String imagePath) {
String base64 = null;
byte[] input = null;
try{
FileInputStream fd = new FileInputStream(imagePath);
Bitmap bmt = BitmapFactory.decodeFileDescriptor(fd.getFD());
try{
ByteArrayOutputStream stream = new ByteArrayOutputStream();
Bitmap tmp = ProfileActivity.scaleDownBitmap(bmt, 10, this);
tmp.compress(Bitmap.CompressFormat.JPEG, 10, stream);
input = stream.toByteArray();
base64 = Base64.encodeToString(input, Base64.DEFAULT);
//LocalProfileActivity.input = input;
}catch(Exception e){
Log.e(LOG_TAG,"[ONACTIVITYRESULT] Could not bind input to the bytearray: " + e.getMessage());
}
}
catch (Exception e){
Log.e("LocalProfile", "ConvertandSetImagetoBase64: Could not load selected profile image");
}
return base64;
}
content://media/external/images/media/3这就是我要传递给方法的东西。有人能帮我吗

由于要将位置指定为URI,因此可以尝试以下操作:
