1.m指model，在項(xiàng)目中主要是指實(shí)體類和業(yè)務(wù)邏輯處理類
2.v指view，因?yàn)閙vp框架中把model和view進(jìn)行解耦，所以view功能點(diǎn)僅在于布局交互和生命周期的一些應(yīng)用。
3.p指presenter，主要以接口的方式在view和model中進(jìn)行兩者間的信息交互。

下面是我寫(xiě)的一個(gè)簡(jiǎn)單的用戶登錄demo簡(jiǎn)單來(lái)說(shuō)明一下，

其中個(gè)項(xiàng)目中model中的model主要負(fù)責(zé)bean類和邏輯處理類，還有與presenter交互的接口ILogin。
