将bitmap转为File文件

public void saveBitmapFile(Bitmap bitmap) {    File file = new File("storage/emulated/legacy/s.jpg");//将要保存图片的路径    try {        BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(file));        bitmap.compress(Bitmap.CompressFormat.JPEG, 100, bos);        uploadPic(file);        bos.flush();        bos.close();    } catch (IOException e) {        e.printStackTrace();    }}
