Material Design實戰

Material Design簡介

Material Design是谷歌設計師基於傳統的設計原則，結合豐富的創意和科學技術所發明的一套全新的介面設計語言，包含了視覺、運動、互動效果等特性

Toolbar

建立專案時，預設顯示ActionBar。我們用Toolbar來代替ActionBar，因此需要指定一個不帶ActionBar的主題

有兩種：

• Theme.AppCompat.NoActionBar:深色主題，將介面主體顏色設成深色，陪襯顏色設為淡色
• Theme.AppCompat.Light.NoActionBar:淡色主體，將介面主體顏色設成淡色，陪襯顏色設為深色

DrawerLayout

DrawerLayout是一個佈局，可以直接放入兩個直接子控制元件，第一個是主螢幕的內容，第二個是滑動選單中的內容

AppBarLayout

AppBarLayout實際上是一個線性佈局，內部封裝了很多的滾動事件

將Toolbal放在了AppBarLayout裡面，然後在RecycleView對應的下拉重新整理控制元件中使用了 app:layout_behavior="@string/appbar_scrolling_view_behavior"這個屬性，appbar_scrolling_view_behavior這個字串是由Design庫提供的。

當AppBarLayout接收到滾動事件時，它內部的子控制元件可以指定如何去影響這些事件，通過app:layout_scrollFlags屬性就能實現。
app:layout_scrollFlags="scroll|enterAlways|snap"

scroll：表示當RecycleView向上滾動的時候，Toolbar會隨著一起向上滾動並實現隱藏

enterAlways：表示當RecycleView向下滾動的時候，Toolbar會隨著一起向下滾動並重新顯示

snap：表示當Toolbar還沒有完全隱藏或顯示的時候，會根據當前滾動的距離，自動選擇隱藏還是顯示。

CollapsingToolbarLayout

CollapsingToolbarLayout是一個作用於Toolbar基礎之上的佈局，CollapsingToolbarLayout是不能獨立存在的，只能作為AppBarLayout的直接子佈局來使用，AppBarLayout又必須是CoordinatorLayout的子佈局
