Question

我是通过此方法在Dropbox中上传文件：

public void upload() {

        FileInputStream inputStream = null;
        try {
            File file = new File(Environment.getExternalStorageDirectory()
                    .toString() + "/write.txt");
            inputStream = new FileInputStream(file);
            Entry newEntry = mDBApi.putFile("/write.txt", inputStream,
                    file.length(), null, null);
            Log.i("DbExampleLog", "The uploaded file's rev is: " + newEntry.rev);
        } catch (DropboxUnlinkedException e) {
            // User has unlinked, ask them to link again here.
            Log.e("DbExampleLog", "User has unlinked.");
        } catch (DropboxException e) {
            Log.e("DbExampleLog", "Something went wrong while uploading.");
        } catch (FileNotFoundException e) {
            Log.e("DbExampleLog", "File not found.");
        } finally {
            if (inputStream != null) {
                try {
                    inputStream.close();
                } catch (IOException e) {
                }
            }
        }

    }

但是当该文件存在于该文件夹中时，该文件将重命名为write（1）.txt 但我希望如果该文件已经存在于Dropbox共享文件夹中，那么它将被替换。我现在该怎么办？

您可以使用mDBApi.putFileOverwrite代替mDBApi.putFile

如果文件已存在于Dropbox中，如何覆盖？
