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() {
		
	}
	
	@Override
	protected 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));

		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);  
    }  
  
	
	
}

<?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:layout_height="match_parent" >
        </FrameLayout>
    </RelativeLayout>

</TabHost>

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;

	@Override
	protected 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())
		{
			@Override
			public int getCount()
			{
				return mFragments.size();
			}

			@Override

			{

			}
		};

		mViewPager.setAdapter(mAdapter);
		
		/**

		 */
		mViewPager.setOnPageChangeListener(new OnPageChangeListener()
		{

			@Override
			public void onPageSelected(int position)
			{
				//重置所有TextView的字体颜色
				resetTextView();
				switch (position)
				{
				case 0:
				
					mTabLiaotian.removeView(mBadgeViewforLiaotian);

					break;
				}

				currentIndex = position;
			}

			@Override
			public 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
				{

				{

							* (screenWidth / 3));
					mTabLine.setLayoutParams(lp);

				}

			}

			@Override
			public 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));

}
