• 结队编程study


    ##今天针对study进行结队编程,我和搭档张佳慧刚开始误认为SystemBarTintManager,baseActivity是personalActivity跳转的下一个界面,因为这个代码个人中心运行时候是一个空的界面,并且里面默认代码。##

    ##后经过验证SystemBarTintManager,baseActivity是一个沉浸式通知栏,它的运行就相当于美观界面运行,一直运行在程序上方,类似搜索小图层那样。后面我们就开始对personalActivity进行一个优化程序编程,并且对相对的XML进行设计。##

    ##下面是沉浸式通知栏的代码和调用##
