上一篇博客我们学习了Android Design Support Library库中的 是个简单的组件,不了解的童鞋可以参考之前的博客
Android M新控件之FloatingActionButton,TextInputLayout,Snackbar,TabLayout的使用。
这篇博客我们继续学习Design库中的其他四个组件,分别是AppBarLayout,NavigationView,CoordinatorLayout,CollapsingToolbarLayout。
同样,你需要在你的工程中引入
<code class="hljs bash has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">compile <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">'com.android.support:design:22.2.0'</span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>
效果图是这样的
AppBarLayout 是继承LinerLayout实现的一个ViewGroup容器组件,它是为了Material Design设计的App Bar,支持手势滑动操作。
默认的AppBarLayout是垂直方向的,它的作用是把AppBarLayout包裹的内容都作为AppBar。类似上面图片贴出来的效果,代码布局如下:

此处将Toolbar 和Tablayout的组合部分共同构成 AppBar的效果。
注意: AppBarLayout必须作为Toolbar的父布局容器
AppBarLayout是支持手势滑动效果的,不过的跟CoordinatorLayout配合使用,接下来学习一下CoordinatorLayout组件怎么使用?
从开发文档中可以了解到,CoordinatorLayout是一个增强型的FrameLayout。它的作用有两个

从上面布局看到,CoordinatorLayout协调布局中包裹了两个布局,一个是NestedScrollView,一个是AppBarLayout,以及FAB按钮。
我们来看看CoordinatorLayout是怎么来协调这两个子视图手势操作的。
1.由于CoordinatorLayout是FrameLayout布局,我们可以通过
<code class="hljs avrasm has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-label" style="box-sizing: border-box;">android:</span>layout_gravity=<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"bottom|end"</span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>
属性来控制组件在整个布局中的位置,比如上面效果中的FAB就是通过android:layout_gravity=”bottom|end”来确定 FAB的位置在底端的最右边的位置。
2.为了达到上面效果图的手势动画效果,我们必须做如下设置,通过app:layout_scrollFlags=”scroll|enterAlways” 属性来确定哪个组件是可滑动的
设置的layout_scrollFlags有如下几种选项:
我们上面的布局中 给Toolbar设置了app:layout_scrollFlags属性,因此,Toolbar是可以滚动出屏幕,且向下滚动有可以出现。
3.为了使得Toolbar可以滑动,我们必须还得有个条件,就是CoordinatorLayout布局下包裹一个可以滑动的布局,比如 RecyclerView,NestedScrollView(经过测试,ListView,ScrollView不支持)具有滑动效果的组件。并且给这些组件设置如下属性来告诉CoordinatorLayout,该组件是带有滑动行为的组件,然后CoordinatorLayout在接受到滑动时会通知AppBarLayout 中可滑动的Toolbar可以滑出屏幕了。
<code class="hljs perl has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">app:layout_behavior=<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"<span class="hljs-variable" style="color: rgb(102, 0, 102); box-sizing: border-box;">@string</span>/appbar_scrolling_view_behavior"</span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>
总结: 为了使得Toolbar有滑动效果,必须做到如下三点:
<code class="hljs perl has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"> app:layout_behavior=<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"<span class="hljs-variable" style="color: rgb(102, 0, 102); box-sizing: border-box;">@string</span>/appbar_scrolling_view_behavior"</span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>
CollapsingToolbarLayout包裹 Toolbar 的时候提供一个可折叠的 Toolbar,一般作为AppbarLayout的子视图使用。
CollapsingToolbarLayout 提供以下属性和方法是用:
布局代码如下:
<code class="hljs avrasm has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><?xml version=<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"1.0"</span> encoding=<span class="hljs-string" style="color: rgb(0, 136, 0);

总结: CollapsingToolbarLayout主要是提供一个可折叠的Toolbar容器,对容器中的不同视图设置layout_collapseMode折叠模式,来达到不同的折叠效果。
1.Toolbar 的高度layout_height必须固定,不能 “wrap_content”,否则Toolbar不会滑动,也没有折叠效果。
2.为了能让FloatingActionButton也能折叠且消失出现,我们必须给FAB设置锚点属性
<code class="hljs perl has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">app:layout_anchor=<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"<span class="hljs-variable" style="color: rgb(102, 0, 102); box-sizing: border-box;">@id</span>/appbar"</span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>
意思是FAB浮动按钮显示在哪个布局区域。
且设置当前锚点的位置
app:layout_anchorGravity=”bottom|end|right”
意思FAB浮动按钮在这个布局区域的具体位置。
两个属性共同作用才是的FAB 浮动按钮也能折叠消失,出现。
3.给需要有折叠效果的组件设置 layout_collapseMode属性。

其实这次谷歌只是将上面的ListView布局替换成NavigationView了。简化了之前ListView写适配器的繁琐。
先如今布局改成如下:

其中NavigationView 中的 android:layout_gravity=”start” 属性来控制抽屉菜单从哪边滑出,一般“start ”从左边滑出,“end”从右边滑出。
这里最主要的两个属性分别是:
1.app:headerLayout: 给NavigationView添加头部布局
2.app:menu:给NavigationView添加menu菜单布局
app:headerLayout布局如下:
