<h2>Material Design简介</h2> <p>Material Design是谷歌设计师基于传统的设计原则，结合丰富的创意和科学技术所发明的一套全新的界面设计语言，包含了视觉、运动、互动效果等特性</p> <h2>Toolbar</h2> <p>创建项目时，默认显示ActionBar。我们用Toolbar来代替ActionBar，因此需要指定一个不带ActionBar的主题</p> <p>有两种：</p> <ul> <li>Theme.AppCompat.NoActionBar:深色主题，将界面主体颜色设成深色，陪衬颜色设为淡色</li> <li>Theme.AppCompat.Light.NoActionBar:淡色主体，将界面主体颜色设成淡色，陪衬颜色设为深色</li> </ul> <p>activity_main.xml</p> <pre> <code

app:layout_behavior="@string/appbar_scrolling_view_behavior"这个属性，appbar_scrolling_view_behavior这个字符串是由Design库提供的。</p> <p>当AppBarLayout接收到滚动事件时，它内部的子控件可以指定如何去影响这些事件，通过app:layout_scrollFlags属性就能实现。</p> <p>app:layout_scrollFlags="scroll|enterAlways|snap"</p> <p>scroll：表示当RecycleView向上滚动的时候，Toolbar会随着一起向上滚动并实现隐藏</p> <p>enterAlways：表示当RecycleView向下滚动的时候，Toolbar会随着一起向下滚动并重新显示</p> <p>snap：表示当Toolbar还没有完全隐藏或显示的时候，会根据当前滚动的距离，自动选择隐藏还是显示。</p> <p style="text-align:center"><img src="https://simg.open-open.com/show/90c0790056ba228ea6cd80a521ac04c7.gif"></p>
