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!
