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"?><LinearLayoutxmlns: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.TabLayoutandroid: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.ViewPagerandroid: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 --><TextViewandroid: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 {@Overrideprotected 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;}@Overridepublic View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {// Inflate the layout for this fragmentreturn inflater.inflate(R.layout.fragment_blank, container, false);}@Overridepublic 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;}@Overridepublic Fragment getItem(int position) {return BlankFragment.newInstance(list.get(position));}@Overridepublic int getCount() {return list.size();}@Overridepublic 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;@Overrideprotected 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);}@Overridepublic 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;}}
