今天,我着重讲解下如下三个内容:希望对大家能有帮助。--分析版本基于Android2.3。1、WRAP_CONTENT、MATCH_PARENT/FILL_PARENT初入Android殿堂的同学们,对这三个属性一定又爱又恨。爱的是使用起来挺爽地---照葫芦画瓢即可,恨的却是时常混淆这几个属性地意义,需要三思而后行。在带着大家重温下这几个属性的用法吧(希望我没有啰嗦)。这三个属性都用来适应视图的水平或垂直大小,一个以视图的内容或尺寸为基础的布局比精确地指定视图范围更加方便。①fill_parent设置一个视图的布局为fill_parent将强制性地使视图扩展至父元素大小。②match_pare

This paper takes the p-adic representation of integers as the research object to realize the distance measurement of integers in the p-adic metric space. The authors firstly apply the Euclidean algorithm to infer the coefficients of a positive integer in polynomial representation, whose corresponding negative integer can be obtained with the help of the similar solution method of binary complement; secondly, the coefficients are respectively mapped into from mod p to mod the n-th power of p laye
