Android DownloadManager获取文件名

我想您想在

if

块中放入类似的内容。替换

YOUR_DM

为您的DownloadManager实例。

Bundle extras = intent.getExtras();DownloadManager.Query q = new DownloadManager.Query();q.setFilterById(extras.getLong(DownloadManager.EXTRA_DOWNLOAD_ID));Cursor c = YOUR_DM.query(q);if (c.moveToFirst()) {    int status = c.getInt(c.getColumnIndex(DownloadManager.COLUMN_STATUS));    if (status == DownloadManager.STATUS_SUCCESSFUL) {        // process download        title = c.getString(c.getColumnIndex(DownloadManager.COLUMN_TITLE));        // get other required data by changing the constant passed to getColumnIndex    }}
