正确的做法是使用 MediaScannerConnection.scanFile () .scanFile () . 见

简言之:

Instantiate the MediaScannerConnection with a callback.
Connect to it using connect().
In the onMediaScannerConnected() callback, invoke scanFile(path, mimeType) to have the media scanner scan it. Note that the path is absolute and the mime type is optional (may be null).
When you re done, disconnect the MediaScannerConnection, for instance when the onScanCompleted() callback is executed.
