Android程序开发之使用Design包实现QQ动画侧滑效果和滑动菜单导航

google在2015的io大会上，给我们带来了更加详细的material design设计规范，同时，也给我们带来了全新的android design support library，在这个support库里面，google给我们提供了更加规范的md设计风格的控件。最重要的是，android design support library的兼容性更广，直接可以向下兼容到android 2.2。这不得不说是一个良心之作。

使用方法很简单，只需要添加一句依赖

compile 'com.android.support:design:24.0.0'

先用tablayout和snackbar以及navigation实现qq侧滑动画效果和滑动

项目已经同步至：https://github.com/nanchen2251/designnavigation-and-tablayout

上个整体效果图

首先带来的是tablayout

tab滑动切换view并不是一个新的概念，但是google却是第一次在support库中提供了完整的支持，
而且，design library的tablayout 既实现了固定的选项卡 - view的宽度平均分配，
也实现了可滚动的选项卡 - view宽度不固定同时可以横向滚动。选项卡可以在程序中动态添加,
但大部分时间我们都不会这样用，通常滑动布局都会和viewpager配合起来使用，所以，我们需要viewpager来帮忙：
通过一句话setupwithviewpager，我们就把viewpager和tablayout结合了起来。

上个运行图：

看代码

首先是主页面的xml文件

<?xml version="1.0" encoding="utf-8"?>
<linearlayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="com.example.nanchen.designtablayoutdemo.mainactivity">
<android.support.design.widget.tablayout
android:layout_width="match_parent"
app:tabbackground="@color/colorprimarydark"
app:tabtextcolor="@android:color/white"
app:tabselectedtextcolor="#04b4ae"
android:layout_height="wrap_content"
android:id="@+id/main_tab_layout"/>
<android.support.v4.view.viewpager
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:id="@+id/main_vp"/>
</linearlayout>

　　其中由于必须tablayout控件是design包下的，所以必须加上

xmlns:app="http://schemas.android.com/apk/res-auto"<br><br>这样才可以使用自定义它的属性。它的属性有很多，这样简单使用几个，更多的大家可以去尝试。<br>这里，我只滚动了三个，若是你的app tab标签多的话，

app:tabmode="scrollable" 必须指定这个属性，不然你会发现看不到，如果标签数少，还是建议设置为固定的，那样才会等分。

<br><br>其次是fragment的xml文件<br><br>

<framelayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.nanchen.designtablayoutdemo.blankfragment">
<!-- todo: update blank fragment layout -->
<textview
android:layout_width="match_parent"
android:layout_height="match_parent"
android:textsize="30sp"
android:gravity="center"
android:id="@+id/fg_text"
android:text="@string/hello_blank_fragment"/>
</framelayout>

mainactivity.java

package com.example.nanchen.designtablayoutdemo;
import android.os.bundle;
import android.support.design.widget.tablayout;
import android.support.v4.view.viewpager;
import android.support.v7.app.appcompatactivity;
import java.util.arraylist;
import java.util.list;
public class mainactivity extends appcompatactivity {
@override
protected void oncreate(bundle savedinstancestate) {
super.oncreate(savedinstancestate);
setcontentview(r.layout.activity_main);
viewpager vp = (viewpager) findviewbyid(r.id.main_vp);
tablayout tablayout = (tablayout) findviewbyid(r.id.main_tab_layout);
list<string> list = new arraylist<>();
for (int i = 1; i < 4; i++) {
// list.add(string.format(locale.china,"第02d%页",i));
list.add("第"+i+"页");
}
vp.setadapter(new myadapter(getsupportfragmentmanager(),list));
tablayout.setupwithviewpager(vp);
}
}

　　fragment用于存放下面的数据

package com.example.nanchen.designtablayoutdemo;
import android.os.bundle;
import android.support.annotation.nullable;
import android.support.v4.app.fragment;
import android.view.layoutinflater;
import android.view.view;
import android.view.viewgroup;
import android.widget.textview;
/**
* a simple {@link fragment} subclass.
*/
public class blankfragment extends fragment {
public blankfragment() {
// required empty public constructor
}
public static blankfragment newinstance(string text) {
bundle args = new bundle();
args.putstring("text",text);
blankfragment fragment = new blankfragment();
fragment.setarguments(args);
return fragment;
}
@override
public view oncreateview(layoutinflater inflater, viewgroup container,
bundle savedinstancestate) {
// inflate the layout for this fragment
return inflater.inflate(r.layout.fragment_blank, container, false);
}
@override
public void onviewcreated(view view, @nullable bundle savedinstancestate) {
super.onviewcreated(view, savedinstancestate);
textview text = (textview) view.findviewbyid(r.id.fg_text);
string str = getarguments().getstring("text");
text.settext(str);
}
}

需要一个pageradapter

自定义一个。

package com.example.nanchen.designtablayoutdemo;
import android.support.v4.app.fragment;
import android.support.v4.app.fragmentmanager;
import android.support.v4.app.fragmentpageradapter;
import java.util.list;
/**
* created by 南尘 on 2016/7/12.
*/
public class myadapter extends fragmentpageradapter {
private list<string> list;
public myadapter(fragmentmanager fm, list<string> list) {
super(fm);
this.list = list;
}
@override
public fragment getitem(int position) {
return blankfragment.newinstance(list.get(position));
}
@override
public int getcount() {
return list.size();
}
@override
public charsequence getpagetitle(int position) {
return list.get(position);
}
} 

2）再来看看如何使用navigation和drawerlayout实现侧滑功能的动画演示

前面讲解了design包下的tablayout的使用，下面将带来navagationview和drawlayout以及toolbar的联动。

navigationview 通过提供抽屉导航所需的框架让实现更简单，同时它还能够直接通过菜单资源文件直接生成导航元素。把navigationview作为drawerlayout的内容视图来使用。navigationview处理好了和状态栏的关系，可以确保navigationview在api21+设备上正确的和状态栏交互。

以下代码在前面代码的基础上修改。

mainactivity.java

package com.example.nanchen.designtablayoutdemo;
import android.os.bundle;
import android.support.design.widget.navigationview;
import android.support.design.widget.tablayout;
import android.support.v4.view.gravitycompat;
import android.support.v4.view.viewpager;
import android.support.v4.widget.drawerlayout;
import android.support.v7.app.actionbardrawertoggle;
import android.support.v7.app.appcompatactivity;
import android.support.v7.widget.toolbar;
import android.view.menuitem;
import android.widget.toast;
import java.util.arraylist;
import java.util.list;
public class mainactivity extends appcompatactivity implements navigationview.onnavigationitemselectedlistener {
private drawerlayout drawerlayout;
@override
protected void oncreate(bundle savedinstancestate) {
super.oncreate(savedinstancestate);
setcontentview(r.layout.activity_main);
viewpager vp = (viewpager) findviewbyid(r.id.main_vp);
tablayout tablayout = (tablayout) findviewbyid(r.id.main_tab_layout);
toolbar toolbar = (toolbar) findviewbyid(r.id.main_toolbar);
drawerlayout = (drawerlayout) findviewbyid(r.id.main_drawerlayout);
//设置toolbar和drawerlayout实现动画和联动
this.setsupportactionbar(toolbar);
actionbardrawertoggle toggle = new actionbardrawertoggle(this,drawerlayout,toolbar,0,0);
drawerlayout.adddrawerlistener(toggle);//设置监听
toggle.syncstate();//加上同步
getsupportactionbar().setdefaultdisplayhomeasupenabled(true);
list<string> list = new arraylist<>();
for (int i = 1; i < 5; i++) {
// list.add(string.format(locale.china,"第02d%页",i));
list.add("第"+i+"页");
}
vp.setadapter(new myadapter(getsupportfragmentmanager(),list));
tablayout.setupwithviewpager(vp);
navigationview navigationview = (navigationview) findviewbyid(r.id.main_navigation);
navigationview.setnavigationitemselectedlistener(this);
}
@override
public boolean onnavigationitemselected(menuitem item) {
switch (item.getitemid()) {
case r.id.menu_item1:
toast.maketext(this,"你点击了菜单1",toast.length_short).show();
break;
case r.id.menu_item2:
toast.maketext(this,"你点击了菜单2",toast.length_short).show();
break;
case r.id.menu_item3:
toast.maketext(this,"你点击了菜单3",toast.length_short).show();
break;
case r.id.menu_item4:
toast.maketext(this,"你点击了菜单4",toast.length_short).show();
break;
}
drawerlayout.closedrawer(gravitycompat.start);
return true;
}
}
