Android 导航条效果实现 TabLayout+ViewPager+Fragment

书史足自悦,安用勤与劬。这篇文章主要讲述Android 导航条效果实现 TabLayout+ViewPager+Fragment相关的知识,希望能为你提供帮助。
TabLayout一、继承结构

public class TabLayoutextends HorizontalScrollView

java.lang.Object
        ?android.view.View
                ?android.view.ViewGroup
                        ?android.widget.FrameLayout
                                ?android.widget.HorizontalScrollView
                                        ?android.support.design.widget.TabLayout
二、TabLayout的使用1、TabLayout简单使用
  • TabLayout来自design兼容包,使用需要添加依赖。android studio 添加依赖如下:
dependencies { ~~~ compile ‘com.android.support:appcompat-v7:23.4.0‘ compile ‘com.android.support:design:24.2.0‘ }



  • TabLayout可以水平放置一些tab标签


  • 标签的展示通过 TabLayout.Tab的实例来实现,通过 newTab()方法可以创建这些示例,并且可以通过 setText(int)setIcon(int)方法分别设置标签的文本的图标。 另外,需要通过layout的setTab(Tab)方法把一个标签展示出来。例如:
tabLayout = (TabLayout)findViewById(R.id.tablayout); tabLayout.addTab(tabLayout.newTab().setText("Tab 1")); tabLayout.addTab(tabLayout.newTab().setText("Tab 2")); tabLayout.addTab(tabLayout.newTab().setText("Tab 3"));

  • 你需要通过setOnTabSelectedListener(OnTabSelectedListener)方法,来给标签的选择改变设定一个监听器。当选择状态改变的时候,会通知你的监听器。
  • 你在布局中也可以通过使用TabItem标签给TabLayout设置子标签,例如:
< android.support.design.widget.TabLayout android:layout_width="match_parent" android:layout_height="wrap_content"> < android.support.design.widget.TabItem android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="标签" /> < android.support.design.widget.TabItem android:layout_width="wrap_content" android:layout_height="wrap_content" android:icon="@mipmap/ic_launcher" /> < /android.support.design.widget.TabLayout>

效果如下:

方法一:如果你将TabLayout与ViewPager一起使用,你可以通过调用setupWithViewPager(ViewPager)方法来绑定绑定两个控件。TabLayout将自动出现在ViewPager的标题位置。
方法如下:
MainActivity.java
package com.noonecode.tablayoutdemo; import android.support.design.widget.TabLayout; import android.support.v4.app.Fragment; import android.support.v4.app.FragmentManager; import android.support.v4.app.FragmentPagerAdapter; import android.support.v4.view.ViewPager; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import java.util.ArrayList; import java.util.List; public class MainActivity extends AppCompatActivity {private TabLayout tabLayout; private ViewPager viewPager; private List< Fragment> list; private MyAdapter adapter; private String[] titles = {"页面1", "页面2", "页面3"}; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); //实例化 viewPager = (ViewPager) findViewById(R.id.viewpager); tabLayout = (TabLayout) findViewById(R.id.tablayout); //页面,数据源 list = new ArrayList< > (); list.add(new Tab1Fragment()); list.add(new Tab2Fragment()); list.add(new Tab3Fragment()); //ViewPager的适配器 adapter = new MyAdapter(getSupportFragmentManager()); viewPager.setAdapter(adapter); //绑定 tabLayout.setupWithViewPager(viewPager); }class MyAdapter extends FragmentPagerAdapter {public MyAdapter(FragmentManager fm) { super(fm); } @Override public Fragment getItem(int position) { return list.get(position); }@Override public int getCount() { return list.size(); }//重写这个方法,将设置每个Tab的标题 @Override public CharSequence getPageTitle(int position) { return titles[position]; } } }

activity_main.java
< ?xml version="1.0" encoding="utf-8"?> < LinearLayout 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" android:orientation="vertical" tools:context="com.noonecode.tablayoutdemo.MainActivity"> < android.support.design.widget.TabLayout android:id="@+id/tablayout" android:layout_width="match_parent" android:layout_height="wrap_content" /> < android.support.v4.view.ViewPager android:id="@+id/viewpager" android:layout_width="match_parent" android:layout_height="0dp" android:layout_weight="1"> < /android.support.v4.view.ViewPager> < /LinearLayout>




方法二:TabLayout也支持当作ViewPager的装饰来使用,通过在布局中直接把它添加到ViewPager的内部(将自动将ViewPager的标题作为TabLayout的Tab)
如下方式使用:
MainActivity.java
package com.noonecode.tablayoutdemo; import android.support.design.widget.TabLayout; import android.support.v4.app.Fragment; import android.support.v4.app.FragmentManager; import android.support.v4.app.FragmentPagerAdapter; import android.support.v4.view.ViewPager; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import java.util.ArrayList; import java.util.List; public class MainActivity extends AppCompatActivity {private ViewPager viewPager; private List< Fragment> list; private MyAdapter adapter; private String[] titles = {"页面1", "页面2", "页面3"}; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); //实例化 viewPager = (ViewPager) findViewById(R.id.viewpager); //页面,数据源 list = new ArrayList< > (); list.add(new Tab1Fragment()); list.add(new Tab2Fragment()); list.add(new Tab3Fragment()); //ViewPager的适配器 adapter = new MyAdapter(getSupportFragmentManager()); viewPager.setAdapter(adapter); }class MyAdapter extends FragmentPagerAdapter {...//重写这个方法,将设置每个Tab的标题 @Override public CharSequence getPageTitle(int position) { return titles[position]; } } }

activity_main.java
< ?xml version="1.0" encoding="utf-8"?> < LinearLayout 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" android:orientation="vertical" tools:context="com.noonecode.tablayoutdemo.MainActivity"> < android.support.v4.view.ViewPager android:id="@+id/viewpager" android:layout_width="match_parent" android:layout_height="match_parent"> < android.support.design.widget.TabLayout android:id="@+id/tablayout" android:layout_width="match_parent" android:layout_height="wrap_content" /> < /android.support.v4.view.ViewPager> < /LinearLayout>

实现方法:
TabLayout默认可以实现图示的效果的,比较简单,这里讲述,如何自定义效果。
可以自定义每个Tab的的布局样式,实现丰富的效果。如下:
tab_custom.xml
< ?xml version="1.0" encoding="utf-8"?> < LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:gravity="center" android:orientation="vertical"> < ImageView android:id="@+id/iv_icon" android:layout_width="30dp" android:layout_height="30dp" /> < TextView android:id="@+id/tv_title" android:layout_width="wrap_content" android:layout_height="wrap_content" /> < /LinearLayout>

activity_main.xml
这里需要把指示条隐藏掉:tabIndicatorHeight="0dp"
< ?xml version="1.0" encoding="utf-8"?> < LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" tools:context="com.noonecode.tablayoutdemo.MainActivity"> < android.support.v4.view.ViewPager android:id="@+id/viewpager" android:layout_width="match_parent" android:layout_height="0dp" android:layout_weight="1"/> < android.support.design.widget.TabLayout android:id="@+id/tablayout" android:layout_width="match_parent" android:layout_height="60dp" app:tabSelectedTextColor="#59D" app:tabTextColor="#999" app:tabIndicatorHeight="0dp" /> < /LinearLayout>

MainActivity.java
package com.noonecode.tablayoutdemo; import android.content.Context; import android.support.design.widget.TabLayout; import android.support.v4.app.Fragment; import android.support.v4.app.FragmentManager; import android.support.v4.app.FragmentPagerAdapter; import android.support.v4.view.ViewPager; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.view.LayoutInflater; import android.view.View; import android.widget.ImageView; import android.widget.TextView; import java.util.ArrayList; import java.util.List; public class MainActivity extends AppCompatActivity {private TabLayout tabLayout; private ViewPager viewPager; private List< Fragment> list; private MyAdapter adapter; private String[] titles = {"主页", "群组", "搜索", "消息", "更多"}; private int images[] = {R.drawable.home_selector, R.drawable.group_selector, R.drawable.square_selector, R.drawable.message_selector, R.drawable.more_selector}; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); //实例化 viewPager = (ViewPager) findViewById(R.id.viewpager); tabLayout = (TabLayout) findViewById(R.id.tablayout); //页面,数据源 list = new ArrayList< > (); list.add(new Tab1Fragment()); list.add(new Tab2Fragment()); list.add(new Tab3Fragment()); list.add(new Tab4Fragment()); list.add(new Tab5Fragment()); //ViewPager的适配器 adapter = new MyAdapter(getSupportFragmentManager(), this); viewPager.setAdapter(adapter); //绑定 tabLayout.setupWithViewPager(viewPager); //设置自定义视图 for (int i = 0; i < tabLayout.getTabCount(); i++) { TabLayout.Tab tab = tabLayout.getTabAt(i); tab.setCustomView(adapter.getTabView(i)); } }class MyAdapter extends FragmentPagerAdapter {private Context context; public MyAdapter(FragmentManager fm, Context context) { super(fm); this.context = context; }@Override public Fragment getItem(int position) { return list.get(position); }@Override public int getCount() { return list.size(); }/** * 自定义方法,提供自定义Tab * * @param position 位置 * @return 返回Tab的View */ public View getTabView(int position) { View v = LayoutInflater.from(context).inflate(R.layout.tab_custom, null); TextView textView = (TextView) v.findViewById(R.id.tv_title); ImageView imageView = (ImageView) v.findViewById(R.id.iv_icon); textView.setText(titles[position]); imageView.setImageResource(images[position]); //添加一行,设置颜色 textView.setTextColor(tabLayout.getTabTextColors()); // return v; } } }

home_selector.xml,其他的类似
< ?xml version="1.0" encoding="utf-8"?> < selector xmlns:android="http://schemas.android.com/apk/res/android"> < item android:drawable="@mipmap/icon_home_sel" android:state_selected="true" /> < item android:drawable="@mipmap/icon_home_nor" /> < /selector>

注意
  • TabLayout是5.0出来后的design兼容包内的,如要使用,请手动添加依赖。
  • 本例使用Android Studio导包只需要添加添加依赖,将自动下载项目。
  • 绑定ViewPager之后,将自动将ViewPager的标题作为Tab标签,需要重写适配器的getPageTitle方法给其设置标题。这时,通过addTab添加的Tab将是无效的。
  • AppCompatActivity继承自FragmentActivity,小伙伴们继承自FragmentActivity也是一样使用的。
  • 如有问题请留言。
