1、继承TabActivity
package com.example.yqqmobilesafe;import android.app.TabActivity;import android.content.Intent;import android.os.Bundle;import android.view.Menu;import android.view.View;import android.view.ViewGroup;import android.widget.BaseAdapter;import android.widget.GridView;import android.widget.ImageView;import android.widget.LinearLayout;import android.widget.TabHost;import android.widget.TextView;public class HomeActivity extends TabActivity { private TabHost mTabHost; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_home); initViews(); } private void initViews() {mTabHost=getTabHost();//获取到最外层的容器.Intent intent1=new Intent(this,OftenUseFunctionActivity.class);mTabHost.addTab(mTabHost.newTabSpec("tab1").setIndicator("常用功能",getResources().getDrawable(R.drawable.accelerate_selector)).setContent(intent1));Intent intent2=new Intent(this,AppManagerActivity.class);mTabHost.addTab(mTabHost.newTabSpec("tab2").setIndicator("软件管理",getResources().getDrawable(R.drawable.soft_manager_selector)).setContent(intent2));Intent intent3=new Intent(this,SafeProtectActivity.class);mTabHost.addTab(mTabHost.newTabSpec("tab3").setIndicator("安全防护",getResources().getDrawable(R.drawable.security_selector)).setContent(intent3));Intent intent4=new Intent(this,PrivateProtectActivity.class);mTabHost.addTab(mTabHost.newTabSpec("tab4").setIndicator("隐私保护",getResources().getDrawable(R.drawable.profile_selector)).setContent(intent4));} @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.home, menu); return true; } } 布局文件：
activity_home.xml
<pre name="code" class="html"><TabHost xmlns:android="http://schemas.android.com/apk/res/android" android:id="@android:id/tabhost" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="#ffffff" > <RelativeLayout android:layout_width="fill_parent" android:layout_height="fill_parent" > <TabWidget android:layout_alignParentBottom="true" android:id="@android:id/tabs" android:layout_width="fill_parent" android:background="#11ff52" android:layout_height="wrap_content" > </TabWidget> <FrameLayout android:layout_marginBottom="60dip" android:id="@android:id/tabcontent" android:layout_width="fill_parent" android:layout_height="fill_parent" > </FrameLayout> </RelativeLayout></TabHost>
效果如下:

2、没有继承TabActivity
/** * 初始化UI组件 */private void initViews() {setContentView(R.layout.activity_home);mTabHost=(TabHost)this.findViewById(R.id.tabhost);mTabHost.setup();mTabHost.addTab(mTabHost.newTabSpec("tab1").setIndicator("第一个",getResources().getDrawable(R.drawable.unresloved_selector)).setContent(R.id.lv_leave_infos));mTabHost.addTab(mTabHost.newTabSpec("tab2").setIndicator("第二个", getResources().getDrawable(R.drawable.leave_apply_selector)).setContent(R.id.ll_tb_leave_apply));mTabHost.addTab(mTabHost.newTabSpec("tab3").setIndicator("第三个", getResources().getDrawable(R.drawable.exception_note_selector)).setContent(R.id.ll_tb_leave_excepiton_note));mTabHost.setCurrentTabByTag("tab1");mleaveInfos=new ArrayList<LeaveInfo>();mLeaveInfosDao=new LeaveInfosDao(HomeActivity.this);mAcceptLeaveInfoDao=new AcceptLeaveInfosDao(HomeActivity.this);mRejectLeaveInfoDao=new RejectLeaveInfosDao(HomeActivity.this);//mLLloading=(View)this.findViewById(R.id.ll_loading);mLVleaveInfos=(ListView)this.findViewById(R.id.lv_leave_infos);fillData();} 该acticity对应的布局文件：
<?xml version="1.0" encoding="utf-8"?><TabHost xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/tabhost" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_marginBottom="1dp" android:background="#ffffff" android:orientation="vertical" > <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <FrameLayout android:id="@android:id/tabcontent" android:layout_width="match_parent" android:layout_height="wrap_content" > <!-- 第一个 --> <LinearLayout android:id="@+id/ll_tb_unresolve" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <RelativeLayout android:layout_width="match_parent" android:layout_height="50dp" android:background="@drawable/tabitem_bgpress" > <TextView android:id="@+id/tv_app_sys" android:layout_width="wrap_content" android:layout_height="45dp" android:layout_marginLeft="5dp" android:gravity="center_vertical" android:text="@string/ehr_manager_system" android:textColor="#ffffff" /> <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:layout_alignParentTop="true" android:clickable="true" android:onClick="addInfo" android:src="@drawable/add_selector" /> </RelativeLayout> <ListView android:id="@+id/lv_leave_infos" android:layout_width="match_parent" android:layout_height="wrap_content" /> </LinearLayout> <!-- 第2个 --> <LinearLayout android:layout_marginTop="45dp" android:id="@+id/ll_tb_leave_apply" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <ListView android:id="@+id/lv_leave_info_accept" android:layout_width="match_parent" android:layout_height="wrap_content" /> </LinearLayout> <!-- 第3个 --> <LinearLayout android:layout_marginTop="45dp" android:id="@+id/ll_tb_leave_excepiton_note" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <!-- 加载数据时候显示 --> <ListView android:id="@+id/lv_leave_info_reject" android:layout_width="match_parent" android:layout_height="wrap_content" /> </LinearLayout> </FrameLayout> </LinearLayout> <TabWidget android:id="@android:id/tabs" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_gravity="bottom" /></TabHost>
给导航设置监听：
/** * 设置监听 */private void setListener(){mTabHost.setOnTabChangedListener(new TabHost.OnTabChangeListener() {@Overridepublic void onTabChanged(String tabId) {if(tabId.equals("tab1")){//mLVleaveInfos=(ListView)findViewById(R.id.lv_leave_infos);fillData();Log.i("导航","第一个");}else if(tabId.equals("tab2")){mLVleaveInfosAccept=(ListView)findViewById(R.id.lv_leave_info_accept);fillDataAccept();showDeleteOrNo();//是否删除记录Log.i("导航","第二个");}else if(tabId.equals("tab3")){mLVleaveInfoReject=(ListView)findViewById(R.id.lv_leave_info_reject);fillDataReject();showDeleteOrNoReject();//是否删除记录Log.i("导航","第三个");}}}); 3、ViewPager实现导航效果
public class MainWeixin extends Activity {public static MainWeixin instance = null; private ViewPager mTabPager;private ImageView mTabImg;// 动画图片private ImageView mTab1,mTab2,mTab3,mTab4;private int zero = 0;// 动画图片偏移量private int currIndex = 0;// 当前页卡编号private int one;//单个水平动画位移private int two;private int three;private LinearLayout mClose; private LinearLayout mCloseBtn; private View layout;private boolean menu_display = false;private PopupWindow menuWindow;private LayoutInflater inflater;//private Button mRightBtn; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main_weixin); //启动activity时不自动弹出软键盘 getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN); instance = this; /* mRightBtn = (Button) findViewById(R.id.right_btn);

main_weixin.xml
<pre name="code" class="html"><?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/mainweixin" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" android:background="#eee" > <RelativeLayout android:id="@+id/main_bottom" android:layout_width="match_parent" android:layout_height="55dp" android:layout_alignParentBottom="true" android:orientation="vertical" android:background="@drawable/bottom_bar" > <ImageView android:id="@+id/img_tab_now" android:layout_width="wrap_content" android:layout_height="wrap_content" android:scaleType="matrix" android:layout_gravity="bottom" android:layout_alignParentBottom="true" android:src="@drawable/tab_bg" /> <LinearLayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:paddingBottom="2dp" > <LinearLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="center_horizontal" android:orientation="vertical" android:layout_weight="1"> <ImageView android:id="@+id/img_weixin" android:layout_width="wrap_content" android:layout_height="wrap_content" android:scaleType="matrix" android:clickable="true" android:src="@drawable/tab_weixin_pressed" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="微信" android:textColor="#fff" android:textSize="12sp" /> </LinearLayout> <LinearLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="center_horizontal" android:orientation="vertical" android:layout_weight="1"> <ImageView android:id="@+id/img_address" android:layout_width="wrap_content" android:layout_height="wrap_content" android:scaleType="matrix" android:clickable="true" android:src="@drawable/tab_address_normal" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="通讯录" android:textColor="#fff" android:textSize="12sp" /> </LinearLayout> <LinearLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="center_horizontal" android:orientation="vertical" android:layout_weight="1"> <ImageView android:id="@+id/img_friends" android:layout_width="wrap_content" android:layout_height="wrap_content" android:scaleType="matrix" android:clickable="true" android:src="@drawable/tab_find_frd_normal" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="朋友们" android:textColor="#fff" android:textSize="12sp" /> </LinearLayout> <LinearLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="center_horizontal" android:orientation="vertical" android:layout_weight="1"> <ImageView android:id="@+id/img_settings" android:layout_width="wrap_content" android:layout_height="wrap_content" android:scaleType="matrix" android:clickable="true" android:src="@drawable/tab_settings_normal" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="设置" android:textColor="#fff" android:textSize="12sp" /> </LinearLayout> </LinearLayout> </RelativeLayout> <LinearLayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:layout_above="@id/main_bottom" android:orientation="vertical" > <android.support.v4.view.ViewPager android:id="@+id/tabpager" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" > </android.support.v4.view.ViewPager> </LinearLayout> </RelativeLayout>
4、实现导航的滑动功能（继承TabActivity）
package com.example.yqqmobilesafe;import android.app.TabActivity;import android.content.Intent;import android.os.Bundle;import android.util.Log;import android.view.GestureDetector;import android.view.GestureDetector.SimpleOnGestureListener;import android.view.MotionEvent;import android.view.View;import android.widget.TabHost;/** * 骚扰拦截 * @author yqq * */public class StopAnonyActivity extends TabActivity {private TabHost mTabHost;private static final int SWIPE_MIN_DISTANCE = 120; private static final int SWIPE_MAX_OFF_PATH = 250; private static final int SWIPE_THRESHOLD_VELOCITY = 200; private GestureDetector gestureDetector; View.OnTouchListener gestureListener; int currentView = 0; private static int maxTabIndex = 2;public StopAnonyActivity() {}@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);init(); gestureDetector = new GestureDetector(new MyGestureDetector()); gestureListener = new View.OnTouchListener() { public boolean onTouch(View v, MotionEvent event) { if (gestureDetector.onTouchEvent(event)) { return true; } return false; } }; }/** * 初始化 */private void init() {setContentView(R.layout.activity_stop_annoy);mTabHost=getTabHost();Intent intent1=new Intent(StopAnonyActivity.this,RubishSmsActivity.class);mTabHost.addTab(mTabHost.newTabSpec("tab1").setIndicator("垃圾短信").setContent(intent1));Intent intent2=new Intent(StopAnonyActivity.this,AnnoyCallActivity.class);mTabHost.addTab(mTabHost.newTabSpec("tab2").setIndicator("骚扰电话").setContent(intent2));Intent intent3=new Intent(StopAnonyActivity.this,StopAnnoySettingActivity.class);mTabHost.addTab(mTabHost.newTabSpec("tab3").setIndicator("拦截设置").setContent(intent3));//从0开始//mTabHost.setCurrentTab(1);} // 左右滑动刚好页面也有滑动效果 class MyGestureDetector extends SimpleOnGestureListener { @Override public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) { TabHost tabHost = getTabHost(); try { if (Math.abs(e1.getY() - e2.getY()) > SWIPE_MAX_OFF_PATH) return false; // right to left swipe if (e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) { Log.i("test", "right"); if (currentView == maxTabIndex) { currentView = 0; } else { currentView++; } tabHost.setCurrentTab(currentView); } else if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) { Log.i("test", "left"); if (currentView == 0) { currentView = maxTabIndex; } else { currentView--; } tabHost.setCurrentTab(currentView); } } catch (Exception e) { } return false; } } public boolean dispatchTouchEvent(MotionEvent event) { if (gestureDetector.onTouchEvent(event)) { event.setAction(MotionEvent.ACTION_CANCEL); } return super.dispatchTouchEvent(event); } } 对应布局文件：
activity_stop_annoy.xml
<?xml version="1.0" encoding="utf-8"?><TabHost xmlns:android="http://schemas.android.com/apk/res/android" android:id="@android:id/tabhost" android:layout_width="match_parent" android:layout_height="match_parent" > <RelativeLayout android:layout_width="match_parent" android:layout_height="match_parent" > <TabWidget android:background="@drawable/light_green" android:id="@android:id/tabs" android:layout_width="match_parent" android:layout_height="50dp" > </TabWidget> <FrameLayout android:id="@android:id/tabcontent" android:layout_width="match_parent" android:layout_height="match_parent" > </FrameLayout> </RelativeLayout></TabHost>
效果图：
5、用FragmentActivity实现导航
public class MainActivity extends FragmentActivity{private ViewPager mViewPager;private FragmentPagerAdapter mAdapter;private List<Fragment> mFragments = new ArrayList<Fragment>();/** * 顶部三个LinearLayout */private LinearLayout mTabLiaotian;private LinearLayout mTabFaxian;private LinearLayout mTabTongxunlun;/** * 顶部的三个TextView */private TextView mLiaotian;private TextView mFaxian;private TextView mTongxunlu;/** * 分别为每个TabIndicator创建一个BadgeView */private BadgeView mBadgeViewforLiaotian;private BadgeView mBadgeViewforFaxian;private BadgeView mBadgeViewforTongxunlu;/** * Tab的那个引导线 */private ImageView mTabLine;/** * ViewPager的当前选中页 */private int currentIndex;/** * 屏幕的宽度 */private int screenWidth;@Overrideprotected void onCreate(Bundle savedInstanceState){super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);mViewPager = (ViewPager) findViewById(R.id.id_viewpager);initView();initTabLine();/** * 初始化Adapter */mAdapter = new FragmentPagerAdapter(getSupportFragmentManager()){@Overridepublic int getCount(){return mFragments.size();}@Overridepublic Fragment getItem(int arg0){return mFragments.get(arg0);}};mViewPager.setAdapter(mAdapter);/** * 设置监听 */mViewPager.setOnPageChangeListener(new OnPageChangeListener(){@Overridepublic void onPageSelected(int position){//重置所有TextView的字体颜色resetTextView();switch (position){case 0:mTabLiaotian.removeView(mBadgeViewforLiaotian);mBadgeViewforLiaotian.setBadgeCount(5);mTabLiaotian.addView(mBadgeViewforLiaotian);mLiaotian.setTextColor(getResources().getColor(R.color.green));break;case 1:mFaxian.setTextColor(getResources().getColor(R.color.green));mTabFaxian.removeView(mBadgeViewforFaxian);mBadgeViewforFaxian.setBadgeCount(15);mTabFaxian.addView(mBadgeViewforFaxian);break;case 2:mTongxunlu.setTextColor(getResources().getColor(R.color.green));break;}currentIndex = position;}@Overridepublic void onPageScrolled(int position, float positionOffset, int positionOffsetPixels){/** * 利用position和currentIndex判断用户的操作是哪一页往哪一页滑动 * 然后改变根据positionOffset动态改变TabLine的leftMargin */if (currentIndex == 0 && position == 0)// 0->1{LinearLayout.LayoutParams lp = (android.widget.LinearLayout.LayoutParams) mTabLine.getLayoutParams();lp.leftMargin = (int) (positionOffset * (screenWidth * 1.0 / 3) + currentIndex * (screenWidth / 3));mTabLine.setLayoutParams(lp);} else if (currentIndex == 1 && position == 0) // 1->0{LinearLayout.LayoutParams lp = (android.widget.LinearLayout.LayoutParams) mTabLine.getLayoutParams();lp.leftMargin = (int) (-(1 - positionOffset) * (screenWidth * 1.0 / 3) + currentIndex* (screenWidth / 3));mTabLine.setLayoutParams(lp);} else if (currentIndex == 1 && position == 1) // 1->2{LinearLayout.LayoutParams lp = (android.widget.LinearLayout.LayoutParams) mTabLine.getLayoutParams();lp.leftMargin = (int) (positionOffset * (screenWidth * 1.0 / 3) + currentIndex * (screenWidth / 3));mTabLine.setLayoutParams(lp);} else if (currentIndex == 2 && position == 1) // 2->1{LinearLayout.LayoutParams lp = (android.widget.LinearLayout.LayoutParams) mTabLine.getLayoutParams();lp.leftMargin = (int) (-(1 - positionOffset) * (screenWidth * 1.0 / 3) + currentIndex* (screenWidth / 3));mTabLine.setLayoutParams(lp);}}@Overridepublic void onPageScrollStateChanged(int state){}});mViewPager.setCurrentItem(1);}/** * 根据屏幕的宽度，初始化引导线的宽度 */private void initTabLine(){mTabLine = (ImageView) findViewById(R.id.id_tab_line);DisplayMetrics outMetrics = new DisplayMetrics();getWindow().getWindowManager().getDefaultDisplay().getMetrics(outMetrics);screenWidth = outMetrics.widthPixels;LinearLayout.LayoutParams lp = (android.widget.LinearLayout.LayoutParams) mTabLine.getLayoutParams();lp.width = screenWidth / 3;mTabLine.setLayoutParams(lp);}/** * 重置颜色 */protected void resetTextView(){mLiaotian.setTextColor(getResources().getColor(R.color.black));mFaxian.setTextColor(getResources().getColor(R.color.black));mTongxunlu.setTextColor(getResources().getColor(R.color.black));}/** * 初始化控件，初始化Fragment */private void initView(){mTabLiaotian = (LinearLayout) findViewById(R.id.id_tab_liaotian_ly);mTabFaxian = (LinearLayout) findViewById(R.id.id_tab_faxian_ly);mTabTongxunlun = (LinearLayout) findViewById(R.id.id_tab_tongxunlu_ly);mLiaotian = (TextView) findViewById(R.id.id_liaotian);mFaxian = (TextView) findViewById(R.id.id_faxian);mTongxunlu = (TextView) findViewById(R.id.id_tongxunlu);MainTab01 tab01 = new MainTab01();MainTab02 tab02 = new MainTab02();MainTab03 tab03 = new MainTab03();mFragments.add(tab01);mFragments.add(tab02);mFragments.add(tab03);mBadgeViewforFaxian = new BadgeView(this);mBadgeViewforLiaotian = new BadgeView(this);mBadgeViewforTongxunlu = new BadgeView(this);}} 对应布局文件：
