Material Design实战

Material Design简介

Material
Design是谷歌设计师依据传统的统一筹划基准,结合丰硕的新意和科学和技术所发明的一套全新的界面设计语言,包涵了视觉、运动、互动作效果应等风味

Toolbar

创制项目时,默认彰显ActionBar。我们用Toolbar来代替ActionBar,由此要求内定二个不带ActionBar的宗旨

有两种:

  • Theme.AppCompat.NoActionBar:深色主旨,将界面主体颜色设成深色,陪衬颜色设为淡色
  • 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

每二个item都以3个CardView

AppBarLayout

AppBarLayout实际上是多少个线性布局,内部封装了无数的轮转事件

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_height="match_parent">

        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <android.support.design.widget.AppBarLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content">

            <android.support.v7.widget.Toolbar
                android:id="@+id/toolbar"
                android:layout_width="match_parent"
                android:layout_height="?attr/actionBarSize"
                android:background="?attr/colorPrimary"
                android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
                app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
                app:layout_scrollFlags="scroll|enterAlways|snap" />
        </android.support.design.widget.AppBarLayout>

        <android.support.v4.widget.SwipeRefreshLayout
            android:id="@+id/swipe_refresh"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            app:layout_behavior="@string/appbar_scrolling_view_behavior">

            <android.support.v7.widget.RecyclerView
                android:id="@+id/recycler_view"
                android:layout_width="match_parent"
                android:layout_height="match_parent" />
        </android.support.v4.widget.SwipeRefreshLayout>

        <android.support.design.widget.FloatingActionButton
            android:id="@+id/fab"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="bottom|end"
            android:layout_margin="16dp"
            android:src="@mipmap/ic_done" />
    </android.support.design.widget.CoordinatorLayout>



    <android.support.design.widget.NavigationView
        android:id="@+id/nav_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        app:headerLayout="@layout/nav_header"
        app:menu="@menu/nav_menu" />

</android.support.v4.widget.DrawerLayout>

将Toolbal放在了AppBarLayout里面,然后在RecycleView对应的下拉刷新控件中动用了
app:layout_behavior=”@string/appbar_scrolling_view_behavior”那本天性,appbar_scrolling_view_behavior那个字符串是由Design库提供的。

当AppBarLayout接收到滚动事件时,它当中的子控件能够钦点如何去震慑这么些事件,通过app:layout_scrollFlags属性就能兑现。
app:layout_scrollFlags=”scroll|enterAlways|snap”

scroll:表示当RecycleView向上滚动的时候,Toolbar会随着一起前行滚动并完成隐藏

enterAlways:表示当RecycleView向下滚动的时候,Toolbar会随着一起向下滚动并再度显示

snap:表示当Toolbar还尚未完全隐形或出示的时候,会基于方今滚动的离开,自动选用隐藏依旧显得。

CollapsingToolbarLayout

CollapsingToolbarLayout是1个功用于Toolbar基础之上的布局,CollapsingToolbarLayout是不可能独立存在的,只可以作为AppBarLayout的直接子布局来选取,AppBarLayout又无法不是CoordinatorLayout的子布局
