我试图获取下载文件的文件路径,我提供的接收器可以工作,但我怎样才能获得文件名/路径?
内部onReceive
String action = intent.getAction();
if (DownloadManager.ACTION_DOWNLOAD_COMPLETE.equals(action)) {
DownloadManager.Query q = new DownloadManager.Query();
Cursor c = this.query(q); // how to get access to this since there is no instance of DownloadManager
try {
String filePath = c.getString(c.getColumnIndex(DownloadManager.COLUMN_LOCAL_FILENAME));
Log.i("DOWNLOAD LISTENER", filePath);
} catch(Exception e) {
} finally {
c.close();
}
}
无法解析方法查询(...)

df = (pd.read_excel(filename1)
.join(pd.read_excel(filename2, usecols=common_cols),
on=common_cols))
的{{1}}方法查看DownloadManager
