Android现在实现Tab类型的界面方式越来越多,今天就把常见的实现方式给大家来个总结。目前写了:

1、传统的ViewPager实现

2、FragmentManager+Fragment实现

3、ViewPager+FragmentPagerAdapter实现

4、TabPageIndicator+ViewPager+FragmentPagerAdapter

1、传统的ViewPager实现

主要就是ViewPager+ViewAdapter这个还是比较常见的,就不多说了

效果图:

代码:

package com.example.mainframework02;  import javautilArrayList; import javautilList;  import androidappActivity; import androidosBundle; import androidsupportvviewPagerAdapter; import androidsupportvviewViewPager; import androidsupportvviewViewPagerOnPageChangeListener; import androidviewLayoutInflater; import androidviewView; import androidviewViewGroup; import androidwidgetImageButton; import androidwidgetImageView; import androidwidgetLinearLayout;  public class TraditionalViewPagerAcvitity extends Activity {    /**    * ViewPager    */   private ViewPager mViewPager;   /**    * ViewPager的适配器    */   private PagerAdapter mAdapter;   private List<View> mViews;   private LayoutInflater mInflater;      private int currentIndex;    /**    * 底部四个按钮    */   private LinearLayout mTabBtnWeixin;   private LinearLayout mTabBtnFrd;   private LinearLayout mTabBtnAddress;   private LinearLayout mTabBtnSettings;    @Override   protected void onCreate(Bundle savedInstanceState)   {     superonCreate(savedInstanceState);     setContentView(Rlayoutactivity_main);     mInflater = LayoutInflaterfrom(this);     mViewPager = (ViewPager) findViewById(Ridid_viewpager);          /**      * 初始化View      */     initView();          mViewPagersetAdapter(mAdapter);      mViewPagersetOnPageChangeListener(new OnPageChangeListener()     {        @Override       public void onPageSelected(int position)       {         resetTabBtn();         switch (position)         {         case 0:           ((ImageButton) mTabBtnWeixinfindViewById(Ridbtn_tab_bottom_weixin))               setImageResource(Rdrawabletab_weixin_pressed);           break;         case 1:           ((ImageButton) mTabBtnFrdfindViewById(Ridbtn_tab_bottom_friend))               setImageResource(Rdrawabletab_find_frd_pressed);           break;         case 2:           ((ImageButton) mTabBtnAddressfindViewById(Ridbtn_tab_bottom_contact))               setImageResource(Rdrawabletab_address_pressed);           break;         case 3:           ((ImageButton) mTabBtnSettingsfindViewById(Ridbtn_tab_bottom_setting))               setImageResource(Rdrawabletab_settings_pressed);           break;         }          currentIndex = position;       }        @Override       public void onPageScrolled(int arg0, float arg1, int arg2)       {        }        @Override       public void onPageScrollStateChanged(int arg0)       {       }     });    }    protected void resetTabBtn()   {     ((ImageButton) mTabBtnWeixinfindViewById(Ridbtn_tab_bottom_weixin))         setImageResource(Rdrawabletab_weixin_normal);     ((ImageButton) mTabBtnFrdfindViewById(Ridbtn_tab_bottom_friend))         setImageResource(Rdrawabletab_find_frd_normal);     ((ImageButton) mTabBtnAddressfindViewById(Ridbtn_tab_bottom_contact))         setImageResource(Rdrawabletab_address_normal);     ((ImageButton) mTabBtnSettingsfindViewById(Ridbtn_tab_bottom_setting))         setImageResource(Rdrawabletab_settings_normal);   }    private void initView()   {      mTabBtnWeixin = (LinearLayout) findViewById(Ridid_tab_bottom_weixin);     mTabBtnFrd = (LinearLayout) findViewById(Ridid_tab_bottom_friend);     mTabBtnAddress = (LinearLayout) findViewById(Ridid_tab_bottom_contact);     mTabBtnSettings = (LinearLayout) findViewById(Ridid_tab_bottom_setting);      mViews = new ArrayList<View>();     View first = mInflaterinflate(Rlayoutmain_tab_01, null);     View second = mInflaterinflate(Rlayoutmain_tab_02, null);     View third = mInflaterinflate(Rlayoutmain_tab_03, null);     View fourth = mInflaterinflate(Rlayoutmain_tab_04, null);     mViewsadd(first);     mViewsadd(second);     mViewsadd(third);     mViewsadd(fourth);      mAdapter = new PagerAdapter()     {       @Override       public void destroyItem(ViewGroup container, int position, Object object)       {         containerremoveView(mViewsget(position));       }        @Override       public Object instantiateItem(ViewGroup container, int position)       {         View view = mViewsget(position);         containeraddView(view);         return view;       }        @Override       public boolean isViewFromObject(View arg0, Object arg1)       {         return arg0 == arg1;       }        @Override       public int getCount()       {         return mViewssize();       }     };   }  } 

评价:所有的代码都集中在一个Activity中,显得代码比较乱。

2、FragmentManager+Fragment实现

主要利用了Fragment在主内容界面对Fragment的add,hide等事务操作。

效果图:

代码:

主Activity

package com.example.mainframework02.fragment;  import androidannotationSuppressLint; import androidappActivity; import androidappFragmentManager; import androidappFragmentTransaction; import androidosBundle; import androidviewView; import androidviewViewOnClickListener; import androidwidgetImageButton; import androidwidgetLinearLayout;  import comexamplemainframeworkR;  public class FragmentMainActivity extends Activity implements OnClickListener {   private MainTab02 mTab02;   private MainTab01 mTab01;   private MainTab03 mTab03;   private MainTab04 mTab04;    /**    * 底部四个按钮    */   private LinearLayout mTabBtnWeixin;   private LinearLayout mTabBtnFrd;   private LinearLayout mTabBtnAddress;   private LinearLayout mTabBtnSettings;   /**    * 用于对Fragment进行管理    */   private FragmentManager fragmentManager;    @SuppressLint("NewApi")   @Override   protected void onCreate(Bundle savedInstanceState)   {     superonCreate(savedInstanceState);     setContentView(Rlayoutfragment_main);     initViews();     fragmentManager = getFragmentManager();     setTabSelection(0);   }        private void initViews()   {      mTabBtnWeixin = (LinearLayout) findViewById(Ridid_tab_bottom_weixin);     mTabBtnFrd = (LinearLayout) findViewById(Ridid_tab_bottom_friend);     mTabBtnAddress = (LinearLayout) findViewById(Ridid_tab_bottom_contact);     mTabBtnSettings = (LinearLayout) findViewById(Ridid_tab_bottom_setting);      mTabBtnWeixinsetOnClickListener(this);     mTabBtnFrdsetOnClickListener(this);     mTabBtnAddresssetOnClickListener(this);     mTabBtnSettingssetOnClickListener(this);   }    @Override   public void onClick(View v)   {     switch (vgetId())     {     case Ridid_tab_bottom_weixin:       setTabSelection(0);       break;     case Ridid_tab_bottom_friend:       setTabSelection(1);       break;     case Ridid_tab_bottom_contact:       setTabSelection(2);       break;     case Ridid_tab_bottom_setting:       setTabSelection(3);       break;      default:       break;     }   }    /**    * 根据传入的index参数来设置选中的tab页。    *    */   @SuppressLint("NewApi")   private void setTabSelection(int index)   {     // 重置按钮     resetBtn();     // 开启一个Fragment事务     FragmentTransaction transaction = fragmentManagerbeginTransaction();     // 先隐藏掉所有的Fragment,以防止有多个Fragment显示在界面上的情况     hideFragments(transaction);     switch (index)     {     case 0:       // 当点击了消息tab时,改变控件的图片和文字颜色       ((ImageButton) mTabBtnWeixinfindViewById(Ridbtn_tab_bottom_weixin))           setImageResource(Rdrawabletab_weixin_pressed);       if (mTab01 == null)       {         // 如果MessageFragment为空,则创建一个并添加到界面上         mTab01 = new MainTab01();         transactionadd(Ridid_content, mTab01);       } else       {         // 如果MessageFragment不为空,则直接将它显示出来         transactionshow(mTab01);       }       break;     case 1:       // 当点击了消息tab时,改变控件的图片和文字颜色       ((ImageButton) mTabBtnFrdfindViewById(Ridbtn_tab_bottom_friend))           setImageResource(Rdrawabletab_find_frd_pressed);       if (mTab02 == null)       {         // 如果MessageFragment为空,则创建一个并添加到界面上         mTab02 = new MainTab02();         transactionadd(Ridid_content, mTab02);       } else       {         // 如果MessageFragment不为空,则直接将它显示出来         transactionshow(mTab02);       }       break;     case 2:       // 当点击了动态tab时,改变控件的图片和文字颜色       ((ImageButton) mTabBtnAddressfindViewById(Ridbtn_tab_bottom_contact))           setImageResource(Rdrawabletab_address_pressed);       if (mTab03 == null)       {         // 如果NewsFragment为空,则创建一个并添加到界面上         mTab03 = new MainTab03();         transactionadd(Ridid_content, mTab03);       } else       {         // 如果NewsFragment不为空,则直接将它显示出来         transactionshow(mTab03);       }       break;     case 3:       // 当点击了设置tab时,改变控件的图片和文字颜色       ((ImageButton) mTabBtnSettingsfindViewById(Ridbtn_tab_bottom_setting))           setImageResource(Rdrawabletab_settings_pressed);       if (mTab04 == null)       {         // 如果SettingFragment为空,则创建一个并添加到界面上         mTab04 = new MainTab04();         transactionadd(Ridid_content, mTab04);       } else       {         // 如果SettingFragment不为空,则直接将它显示出来         transactionshow(mTab04);       }       break;     }     transactioncommit();   }    /**    * 清除掉所有的选中状态。    */   private void resetBtn()   {     ((ImageButton) mTabBtnWeixinfindViewById(Ridbtn_tab_bottom_weixin))         setImageResource(Rdrawabletab_weixin_normal);     ((ImageButton) mTabBtnFrdfindViewById(Ridbtn_tab_bottom_friend))         setImageResource(Rdrawabletab_find_frd_normal);     ((ImageButton) mTabBtnAddressfindViewById(Ridbtn_tab_bottom_contact))         setImageResource(Rdrawabletab_address_normal);     ((ImageButton) mTabBtnSettingsfindViewById(Ridbtn_tab_bottom_setting))         setImageResource(Rdrawabletab_settings_normal);   }    /**    * 将所有的Fragment都置为隐藏状态。    *    * @param transaction    *      用于对Fragment执行操作的事务    */   @SuppressLint("NewApi")   private void hideFragments(FragmentTransaction transaction)   {     if (mTab01 != null)     {       transactionhide(mTab01);     }     if (mTab02 != null)     {       transactionhide(mTab02);     }     if (mTab03 != null)     {       transactionhide(mTab03);     }     if (mTab04 != null)     {       transactionhide(mTab04);     }        }  } 

各个TabFragment,一共四个TabFragment,下面贴出两个,基本都一样。

package com.example.mainframework02.fragment;  import androidannotationSuppressLint; import androidappFragment; import androidosBundle; import androidviewLayoutInflater; import androidviewView; import androidviewViewGroup;  @SuppressLint("NewApi") public class MainTab01 extends Fragment {    @Override   public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)   {     return inflaterinflate(comexamplemainframeworkRlayoutmain_tab_01, container, false);    }  } package com.example.mainframework02.fragment;  import androidannotationSuppressLint; import androidappFragment; import androidosBundle; import androidviewLayoutInflater; import androidviewView; import androidviewViewGroup;  import comexamplemainframeworkR;  @SuppressLint("NewApi") public class MainTab02 extends Fragment {    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)   {     return inflaterinflate(Rlayoutmain_tab_02, container, false);    }  } 

评价:每个Fragment中的控件的处理,都是独立到各自的类中,相对来说主Activity简化了不少,可惜没有左右滑动的效果了。

3、ViewPager+Fragment实现

主要通过ViewPager和FragmentPagerAdapter一起来实现。

效果图:

代码:

主Activity

package com.example.mainframework03;  import javautilArrayList; import javautilList;  import androidosBundle; import androidsupportvappFragment; import androidsupportvappFragmentActivity; import androidsupportvappFragmentPagerAdapter; import androidsupportvviewViewPager; import androidsupportvviewViewPagerOnPageChangeListener; import androidwidgetImageButton; import androidwidgetLinearLayout;  public class MainActivity extends FragmentActivity {    private ViewPager mViewPager;   private FragmentPagerAdapter mAdapter;   private List<Fragment> mFragments = new ArrayList<Fragment>();         /**    * 底部四个按钮    */   private LinearLayout mTabBtnWeixin;   private LinearLayout mTabBtnFrd;   private LinearLayout mTabBtnAddress;   private LinearLayout mTabBtnSettings;     @Override   protected void onCreate(Bundle savedInstanceState)   {     superonCreate(savedInstanceState);     setContentView(Rlayoutactivity_main);     mViewPager = (ViewPager) findViewById(Ridid_viewpager);           initView();                mAdapter = new FragmentPagerAdapter(getSupportFragmentManager())     {        @Override       public int getCount()       {         return mFragmentssize();       }        @Override       public Fragment getItem(int arg0)       {         return mFragmentsget(arg0);       }     };          mViewPagersetAdapter(mAdapter);               mViewPagersetOnPageChangeListener(new OnPageChangeListener()     {        private int currentIndex;        @Override       public void onPageSelected(int position)       {         resetTabBtn();         switch (position)         {         case 0:           ((ImageButton) mTabBtnWeixinfindViewById(Ridbtn_tab_bottom_weixin))               setImageResource(Rdrawabletab_weixin_pressed);           break;         case 1:           ((ImageButton) mTabBtnFrdfindViewById(Ridbtn_tab_bottom_friend))               setImageResource(Rdrawabletab_find_frd_pressed);           break;         case 2:           ((ImageButton) mTabBtnAddressfindViewById(Ridbtn_tab_bottom_contact))               setImageResource(Rdrawabletab_address_pressed);           break;         case 3:           ((ImageButton) mTabBtnSettingsfindViewById(Ridbtn_tab_bottom_setting))               setImageResource(Rdrawabletab_settings_pressed);           break;         }          currentIndex = position;       }        @Override       public void onPageScrolled(int arg0, float arg1, int arg2)       {        }        @Override       public void onPageScrollStateChanged(int arg0)       {       }     });    }      protected void resetTabBtn()   {     ((ImageButton) mTabBtnWeixinfindViewById(Ridbtn_tab_bottom_weixin))         setImageResource(Rdrawabletab_weixin_normal);     ((ImageButton) mTabBtnFrdfindViewById(Ridbtn_tab_bottom_friend))         setImageResource(Rdrawabletab_find_frd_normal);     ((ImageButton) mTabBtnAddressfindViewById(Ridbtn_tab_bottom_contact))         setImageResource(Rdrawabletab_address_normal);     ((ImageButton) mTabBtnSettingsfindViewById(Ridbtn_tab_bottom_setting))         setImageResource(Rdrawabletab_settings_normal);   }    private void initView()   {      mTabBtnWeixin = (LinearLayout) findViewById(Ridid_tab_bottom_weixin);     mTabBtnFrd = (LinearLayout) findViewById(Ridid_tab_bottom_friend);     mTabBtnAddress = (LinearLayout) findViewById(Ridid_tab_bottom_contact);     mTabBtnSettings = (LinearLayout) findViewById(Ridid_tab_bottom_setting);      MainTab01 tab01 = new MainTab01();     MainTab02 tab02 = new MainTab02();     MainTab03 tab03 = new MainTab03();     MainTab04 tab04 = new MainTab04();     mFragmentsadd(tab01);     mFragmentsadd(tab02);     mFragmentsadd(tab03);     mFragmentsadd(tab04);   } } 

还有4个TabFragment,下面贴一个,四个基本一样

package com.example.mainframework03;  import androidosBundle; import androidsupportvappFragment; import androidviewLayoutInflater; import androidviewView; import androidviewViewGroup;  public class MainTab01 extends Fragment {    @Override   public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)   {     return inflaterinflate(Rlayoutmain_tab_01, container, false);      }  } 

评价:实现效果和第一种效果一模一样,每个Fragment独自处理自己内部的逻辑,代码整洁很多,并且支持左右滑动。感觉是第一种和第二种的结合版本。

4、TabPageIndicator+ViewPager+FragmentPagerAdapter

实现方式和3是一致的,但是使用了TabPageIndicator作为tab的指示器,效果还是不错的,这个之前写过,就不再贴代码了。

效果图:

好了,就总结了这么多,肯定还有很多别的实现方式,大家可以留言,有时间会继续完善这篇总结的。
