android - How to display EditText in a TextView after changing it to BigDecimal? -

-

i want precise number edittext change in bigdecimal , show in textview. here's part of code:

bigdecimal rate_string = new bigdecimal(0); edittext rate = (edittext) findviewbyid(r.id.rate_edittext); rate_string = (bigdecimal) rate.gettext(); textview test = (textview) findviewbyid(r.id.textview1); test.settext(rate_string.tostring());

but doesn't work! should do? thanks

bigdecimal rate_string = new bigdecimal(0); edittext rate = (edittext) findviewbyid(r.id.rate_edittext); rate_string = (bigdecimal) rate.gettext(); textview test = (textview) findviewbyid(r.id.textview1); test.settext(rate_string.tostring());

to

bigdecimal rate_string; // p.s here useless creation edittext rate = (edittext) findviewbyid(r.id.rate_edittext); rate_string = new bigdecimal( rate.gettext().tostring() ); textview test = (textview) findviewbyid(r.id.textview1); test.settext(rate_string.tostring());

you cannot convert string bigdeciaml using cast bigdecimal have constructor takes value string.

p.s make sure pass correct number constructor or throw numberformatexception!

i have implement video collection website users of specific isp. site hosted on public web-server movies hosted on local isp server. user of isp + general visitors can see available movies; isp's users able play them. player on site point url of local machine ( http://192.x.x.x/movies/mymovie.mov ) private class (192.x.x.x) accessible isp user. question: possible phpmotion script? or need custom work. if possible, can please suggest available mods? phpmotion require modifications able handle this. uploading, conversion, thumbnail generation, , playback pretty static in phpmotion. really though, rather modding entire upload , conversion process, if created quick custom form add entries phpmotion database (maybe include thumbnail upload), tweaked playback paths, should go on phpmotion side of things. assume had videos in format player handle (such flv or mp4).
