March 7, Dangdang announced the latest issue of earnings, data show when the fourth quarter of the total revenue of 1.6 billion yuan, 31% year-on-year, at the same time, Dangdang continued to net losses, the loss degree of about 120 million yuan, but slightly narrowed. On the whole, Dangdang's performance in the fourth quarter of 2012 was pretty good from the data. But these figures are not amenable to scrutiny, because from 2012 the overall development of the electric business industry, everyon
0) OverviewShortly before listening to an accomplished old gentleman, he told a lecture about simulation, which involved reductionism and holism. Therefore, through the wisdom of the gentleman, said to carry out the entire complex network analysis process (including the construction of complex networks, the same below) reductionism and holism.This paper first exp

Here, even if the form is very complex, you actually need to expand it to be easy:
1. Encapsulate a observable for each edittext
2. Rewrite this phrase to add new logic:
return isemailvalid (email) ispasswordvalid (password);
Think for each edittext package a observable to write a lot of duplicate code? Don
