Java 安卓：从相机重命名图像

目前，我在应用程序中使用此代码允许用户捕获照片。但是如何更改代码，以便在用户捕获照片后，将其重命名为名称，如“xxxx01.jpg”

试试这个

//camera stuff
Intent imageIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());

//folder stuff
File imagesFolder = new File(Environment.getExternalStorageDirectory(), "MyImages");
imagesFolder.mkdirs();

filePath = "/MyImages/QR_" + timeStamp + ".png" ;
File image = new File(imagesFolder, "QR_" + timeStamp + ".png");
Uri uriSavedImage = Uri.fromFile(image);

imageIntent.putExtra(MediaStore.EXTRA_OUTPUT, uriSavedImage);
startActivityForResult(imageIntent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);

//camera stuff
