android - Converting string to data -
i getting duration of audio file , convert int , convert int string , string 00:32 . converted string correct, problem convert string data
here code:
file file = new file(environment.getexternalstoragedirectory()+"/myimages/.audio1.wav"); mediaplayer mp = new mediaplayer(); fileinputstream fs = null; filedescriptor fd = null; try { fs = new fileinputstream(file); } catch (filenotfoundexception e) { // todo auto-generated catch block e.printstacktrace(); } try { fd = fs.getfd(); } catch (ioexception e) { // todo auto-generated catch block e.printstacktrace(); } try { mp.setdatasource(fd); } catch (illegalargumentexception e) { // todo auto-generated catch block e.printstacktrace(); } catch (illegalstateexception e) { // todo auto-generated catch block e.printstacktrace(); } catch (ioexception e) { // todo auto-generated catch block e.printstacktrace(); } try { mp.prepare(); } catch (illegalstateexception e) { // todo auto-generated catch block e.printstacktrace(); } catch (ioexception e) { // todo auto-generated catch block e.printstacktrace(); } int length = mp.getduration()/1000; mp.release(); string audiotime = string.valueof(length); simpledateformat sdf = new simpledateformat("mmss"); try { date d = sdf.parse(audiotime); textview1.settext(audiotime); } catch (parseexception ex) { }
two things, important, use original string text textview. should textview1.settext(d.tostring());
secondly, should use "mm:ss" format, instead of "mmss".
note use format function of simpledateformat. return stringbuffer, might more appropriate since need string representation
