Android如今實現Tab類型的界面方式愈來愈多,今天就把常見的實現方式給你們來個總結。目前寫了:android
一、傳統的ViewPager實現app
二、FragmentManager+Fragment實現框架
三、ViewPager+FragmentPagerAdapter實現ide
四、TabPageIndicator+ViewPager+FragmentPagerAdapterthis
一、傳統的ViewPager實現
spa
主要就是ViewPager+ViewAdapter這個仍是比較常見的,就很少說了.net

代碼:orm
package com.example.mainframework02; import java.util.ArrayList; import java.util.List; import android.app.Activity; import android.os.Bundle; import android.support.v4.view.PagerAdapter; import android.support.v4.view.ViewPager; import android.support.v4.view.ViewPager.OnPageChangeListener; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.ImageButton; import android.widget.ImageView; import android.widget.LinearLayout; public class TraditionalViewPagerAcvitity extends Activity { /** * ViewPager */ private ViewPager mViewPager; /** * ViewPager的適配器 */ private PagerAdapter mAdapter; private List<View> mViews; private LayoutInflater mInflater; private int currentIndex; /** * 底部四個按鈕 */ private LinearLayout mTabBtnWeixin; private LinearLayout mTabBtnFrd; private LinearLayout mTabBtnAddress; private LinearLayout mTabBtnSettings; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mInflater = LayoutInflater.from(this); mViewPager = (ViewPager) findViewById(R.id.id_viewpager); /** * 初始化View */ initView(); mViewPager.setAdapter(mAdapter); mViewPager.setOnPageChangeListener(new OnPageChangeListener() { @Override public void onPageSelected(int position) { resetTabBtn(); switch (position) { case 0: ((ImageButton) mTabBtnWeixin.findViewById(R.id.btn_tab_bottom_weixin)) .setImageResource(R.drawable.tab_weixin_pressed); break; case 1: ((ImageButton) mTabBtnFrd.findViewById(R.id.btn_tab_bottom_friend)) .setImageResource(R.drawable.tab_find_frd_pressed); break; case 2: ((ImageButton) mTabBtnAddress.findViewById(R.id.btn_tab_bottom_contact)) .setImageResource(R.drawable.tab_address_pressed); break; case 3: ((ImageButton) mTabBtnSettings.findViewById(R.id.btn_tab_bottom_setting)) .setImageResource(R.drawable.tab_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) mTabBtnWeixin.findViewById(R.id.btn_tab_bottom_weixin)) .setImageResource(R.drawable.tab_weixin_normal); ((ImageButton) mTabBtnFrd.findViewById(R.id.btn_tab_bottom_friend)) .setImageResource(R.drawable.tab_find_frd_normal); ((ImageButton) mTabBtnAddress.findViewById(R.id.btn_tab_bottom_contact)) .setImageResource(R.drawable.tab_address_normal); ((ImageButton) mTabBtnSettings.findViewById(R.id.btn_tab_bottom_setting)) .setImageResource(R.drawable.tab_settings_normal); } private void initView() { mTabBtnWeixin = (LinearLayout) findViewById(R.id.id_tab_bottom_weixin); mTabBtnFrd = (LinearLayout) findViewById(R.id.id_tab_bottom_friend); mTabBtnAddress = (LinearLayout) findViewById(R.id.id_tab_bottom_contact); mTabBtnSettings = (LinearLayout) findViewById(R.id.id_tab_bottom_setting); mViews = new ArrayList<View>(); View first = mInflater.inflate(R.layout.main_tab_01, null); View second = mInflater.inflate(R.layout.main_tab_02, null); View third = mInflater.inflate(R.layout.main_tab_03, null); View fourth = mInflater.inflate(R.layout.main_tab_04, null); mViews.add(first); mViews.add(second); mViews.add(third); mViews.add(fourth); mAdapter = new PagerAdapter() { @Override public void destroyItem(ViewGroup container, int position, Object object) { container.removeView(mViews.get(position)); } @Override public Object instantiateItem(ViewGroup container, int position) { View view = mViews.get(position); container.addView(view); return view; } @Override public boolean isViewFromObject(View arg0, Object arg1) { return arg0 == arg1; } @Override public int getCount() { return mViews.size(); } }; } }
評價:全部的代碼都集中在一個Activity中,顯得代碼比較亂。
二、FragmentManager+Fragment實現
主要利用了Fragment在主內容界面對Fragment的add,hide等事務操做。
效果圖:
代碼:
主Activity
package com.example.mainframework02.fragment; import android.annotation.SuppressLint; import android.app.Activity; import android.app.FragmentManager; import android.app.FragmentTransaction; import android.os.Bundle; import android.view.View; import android.view.View.OnClickListener; import android.widget.ImageButton; import android.widget.LinearLayout; import com.example.mainframework02.R; public class FragmentMainActivity extends Activity implements OnClickListener { private MainTab02 mTab02; private MainTab01 mTab01; private MainTab03 mTab03; private MainTab04 mTab04; /** * 底部四個按鈕 */ private LinearLayout mTabBtnWeixin; private LinearLayout mTabBtnFrd; private LinearLayout mTabBtnAddress; private LinearLayout mTabBtnSettings; /** * 用於對Fragment進行管理 */ private FragmentManager fragmentManager; @SuppressLint("NewApi") @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.fragment_main); initViews(); fragmentManager = getFragmentManager(); setTabSelection(0); } private void initViews() { mTabBtnWeixin = (LinearLayout) findViewById(R.id.id_tab_bottom_weixin); mTabBtnFrd = (LinearLayout) findViewById(R.id.id_tab_bottom_friend); mTabBtnAddress = (LinearLayout) findViewById(R.id.id_tab_bottom_contact); mTabBtnSettings = (LinearLayout) findViewById(R.id.id_tab_bottom_setting); mTabBtnWeixin.setOnClickListener(this); mTabBtnFrd.setOnClickListener(this); mTabBtnAddress.setOnClickListener(this); mTabBtnSettings.setOnClickListener(this); } @Override public void onClick(View v) { switch (v.getId()) { case R.id.id_tab_bottom_weixin: setTabSelection(0); break; case R.id.id_tab_bottom_friend: setTabSelection(1); break; case R.id.id_tab_bottom_contact: setTabSelection(2); break; case R.id.id_tab_bottom_setting: setTabSelection(3); break; default: break; } } /** * 根據傳入的index參數來設置選中的tab頁。 * */ @SuppressLint("NewApi") private void setTabSelection(int index) { // 重置按鈕 resetBtn(); // 開啓一個Fragment事務 FragmentTransaction transaction = fragmentManager.beginTransaction(); // 先隱藏掉全部的Fragment,以防止有多個Fragment顯示在界面上的狀況 hideFragments(transaction); switch (index) { case 0: // 當點擊了消息tab時,改變控件的圖片和文字顏色 ((ImageButton) mTabBtnWeixin.findViewById(R.id.btn_tab_bottom_weixin)) .setImageResource(R.drawable.tab_weixin_pressed); if (mTab01 == null) { // 若是MessageFragment爲空,則建立一個並添加到界面上 mTab01 = new MainTab01(); transaction.add(R.id.id_content, mTab01); } else { // 若是MessageFragment不爲空,則直接將它顯示出來 transaction.show(mTab01); } break; case 1: // 當點擊了消息tab時,改變控件的圖片和文字顏色 ((ImageButton) mTabBtnFrd.findViewById(R.id.btn_tab_bottom_friend)) .setImageResource(R.drawable.tab_find_frd_pressed); if (mTab02 == null) { // 若是MessageFragment爲空,則建立一個並添加到界面上 mTab02 = new MainTab02(); transaction.add(R.id.id_content, mTab02); } else { // 若是MessageFragment不爲空,則直接將它顯示出來 transaction.show(mTab02); } break; case 2: // 當點擊了動態tab時,改變控件的圖片和文字顏色 ((ImageButton) mTabBtnAddress.findViewById(R.id.btn_tab_bottom_contact)) .setImageResource(R.drawable.tab_address_pressed); if (mTab03 == null) { // 若是NewsFragment爲空,則建立一個並添加到界面上 mTab03 = new MainTab03(); transaction.add(R.id.id_content, mTab03); } else { // 若是NewsFragment不爲空,則直接將它顯示出來 transaction.show(mTab03); } break; case 3: // 當點擊了設置tab時,改變控件的圖片和文字顏色 ((ImageButton) mTabBtnSettings.findViewById(R.id.btn_tab_bottom_setting)) .setImageResource(R.drawable.tab_settings_pressed); if (mTab04 == null) { // 若是SettingFragment爲空,則建立一個並添加到界面上 mTab04 = new MainTab04(); transaction.add(R.id.id_content, mTab04); } else { // 若是SettingFragment不爲空,則直接將它顯示出來 transaction.show(mTab04); } break; } transaction.commit(); } /** * 清除掉全部的選中狀態。 */ private void resetBtn() { ((ImageButton) mTabBtnWeixin.findViewById(R.id.btn_tab_bottom_weixin)) .setImageResource(R.drawable.tab_weixin_normal); ((ImageButton) mTabBtnFrd.findViewById(R.id.btn_tab_bottom_friend)) .setImageResource(R.drawable.tab_find_frd_normal); ((ImageButton) mTabBtnAddress.findViewById(R.id.btn_tab_bottom_contact)) .setImageResource(R.drawable.tab_address_normal); ((ImageButton) mTabBtnSettings.findViewById(R.id.btn_tab_bottom_setting)) .setImageResource(R.drawable.tab_settings_normal); } /** * 將全部的Fragment都置爲隱藏狀態。 * * @param transaction * 用於對Fragment執行操做的事務 */ @SuppressLint("NewApi") private void hideFragments(FragmentTransaction transaction) { if (mTab01 != null) { transaction.hide(mTab01); } if (mTab02 != null) { transaction.hide(mTab02); } if (mTab03 != null) { transaction.hide(mTab03); } if (mTab04 != null) { transaction.hide(mTab04); } } }
各個TabFragment,一共四個TabFragment,下面貼出兩個,基本都同樣。
package com.example.mainframework02.fragment; import android.annotation.SuppressLint; import android.app.Fragment; import android.os.Bundle; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; @SuppressLint("NewApi") public class MainTab01 extends Fragment { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { return inflater.inflate(com.example.mainframework02.R.layout.main_tab_01, container, false); } }
package com.example.mainframework02.fragment; import android.annotation.SuppressLint; import android.app.Fragment; import android.os.Bundle; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import com.example.mainframework02.R; @SuppressLint("NewApi") public class MainTab02 extends Fragment { public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { return inflater.inflate(R.layout.main_tab_02, container, false); } }
評價:每一個Fragment中的控件的處理,都是獨立到各自的類中,相對來講主Activity簡化了很多,惋惜沒有左右滑動的效果了。
三、ViewPager+Fragment實現
主要經過ViewPager和FragmentPagerAdapter一塊兒來實現。
效果圖:
代碼:
主Activity
package com.example.mainframework03; import java.util.ArrayList; import java.util.List; import android.os.Bundle; import android.support.v4.app.Fragment; import android.support.v4.app.FragmentActivity; import android.support.v4.app.FragmentPagerAdapter; import android.support.v4.view.ViewPager; import android.support.v4.view.ViewPager.OnPageChangeListener; import android.widget.ImageButton; import android.widget.LinearLayout; public class MainActivity extends FragmentActivity { private ViewPager mViewPager; private FragmentPagerAdapter mAdapter; private List<Fragment> mFragments = new ArrayList<Fragment>(); /** * 底部四個按鈕 */ private LinearLayout mTabBtnWeixin; private LinearLayout mTabBtnFrd; private LinearLayout mTabBtnAddress; private LinearLayout mTabBtnSettings; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mViewPager = (ViewPager) findViewById(R.id.id_viewpager); initView(); mAdapter = new FragmentPagerAdapter(getSupportFragmentManager()) { @Override public int getCount() { return mFragments.size(); } @Override public Fragment getItem(int arg0) { return mFragments.get(arg0); } }; mViewPager.setAdapter(mAdapter); mViewPager.setOnPageChangeListener(new OnPageChangeListener() { private int currentIndex; @Override public void onPageSelected(int position) { resetTabBtn(); switch (position) { case 0: ((ImageButton) mTabBtnWeixin.findViewById(R.id.btn_tab_bottom_weixin)) .setImageResource(R.drawable.tab_weixin_pressed); break; case 1: ((ImageButton) mTabBtnFrd.findViewById(R.id.btn_tab_bottom_friend)) .setImageResource(R.drawable.tab_find_frd_pressed); break; case 2: ((ImageButton) mTabBtnAddress.findViewById(R.id.btn_tab_bottom_contact)) .setImageResource(R.drawable.tab_address_pressed); break; case 3: ((ImageButton) mTabBtnSettings.findViewById(R.id.btn_tab_bottom_setting)) .setImageResource(R.drawable.tab_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) mTabBtnWeixin.findViewById(R.id.btn_tab_bottom_weixin)) .setImageResource(R.drawable.tab_weixin_normal); ((ImageButton) mTabBtnFrd.findViewById(R.id.btn_tab_bottom_friend)) .setImageResource(R.drawable.tab_find_frd_normal); ((ImageButton) mTabBtnAddress.findViewById(R.id.btn_tab_bottom_contact)) .setImageResource(R.drawable.tab_address_normal); ((ImageButton) mTabBtnSettings.findViewById(R.id.btn_tab_bottom_setting)) .setImageResource(R.drawable.tab_settings_normal); } private void initView() { mTabBtnWeixin = (LinearLayout) findViewById(R.id.id_tab_bottom_weixin); mTabBtnFrd = (LinearLayout) findViewById(R.id.id_tab_bottom_friend); mTabBtnAddress = (LinearLayout) findViewById(R.id.id_tab_bottom_contact); mTabBtnSettings = (LinearLayout) findViewById(R.id.id_tab_bottom_setting); MainTab01 tab01 = new MainTab01(); MainTab02 tab02 = new MainTab02(); MainTab03 tab03 = new MainTab03(); MainTab04 tab04 = new MainTab04(); mFragments.add(tab01); mFragments.add(tab02); mFragments.add(tab03); mFragments.add(tab04); } }
還有4個TabFragment,下面貼一個,四個基本同樣
package com.example.mainframework03; import android.os.Bundle; import android.support.v4.app.Fragment; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; public class MainTab01 extends Fragment { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { return inflater.inflate(R.layout.main_tab_01, container, false); } }
評價:實現效果和第一種效果如出一轍,每一個Fragment獨自處理本身內部的邏輯,代碼整潔不少,而且支持左右滑動。感受是第一種和第二種的結合版本。
四、TabPageIndicator+ViewPager+FragmentPagerAdapter
實現方式和3是一致的,可是使用了TabPageIndicator做爲tab的指示器,效果仍是不錯的,這個以前寫過,就再也不貼代碼了。
效果圖:
參考:Android 使用Fragment,ViewPagerIndicator 製做csdn app主要框架
好了,就總結了這麼多,確定還有不少別的實現方式,你們能夠留言,有時間會繼續完善這篇總結的。
