android - DownloadManager 不将下载的文件存储在下载文件夹中

Question

每当我尝试通过下面的代码下载任何文件时

dm = (DownloadManager) context.getSystemService(context.DOWNLOAD_SERVICE);
request = new Request(
    Uri.parse(finalurl));
enqueue = dm.enqueue(request);

BroadcastReceiver receiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            String action = intent.getAction();
            if (DownloadManager.ACTION_DOWNLOAD_COMPLETE.equals(action)) {
                long downloadId = intent.getLongExtra(
                        DownloadManager.EXTRA_DOWNLOAD_ID, 0);
                Query query = new Query();
                query.setFilterById(enqueue);
                Cursor c = dm.query(query);
                if (c.moveToFirst()) {
                    int columnIndex = c
                            .getColumnIndex(DownloadManager.COLUMN_STATUS);
                    if (DownloadManager.STATUS_SUCCESSFUL == c
                            .getInt(columnIndex)) {

                        Toast.makeText(context, "download finished", Toast.LENGTH_LONG).show();
                    }
                }
            }
        }
    };

    context.registerReceiver(receiver, new IntentFilter(
            DownloadManager.ACTION_DOWNLOAD_COMPLETE));

下载的文件显示在下载管理器应用程序中，可以随时从那里播放，但不会将下载的文件存储在下载文件夹中。

如果我用

.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, "filename.extention"));

我得到了相同的结果。

我的问题是——我的下载要去哪里以及如何将它们带到下载文件夹？

Answer 1

尝试

request.setDestinationInExternalPublicDir("/folder","file.ext");

这会将文件保存到

Environment.getExternalStorageDirectory() + "/folder"
