ViewPager讲解以及ViewFlipper

1.加入ViewPager最好导入兼容低版本

2.将布局转换为View的方法

 

3.适配器类型

PagerAdapter数据适配器,以View（4个View配置文件）作为数据对象填充 
课程Demo
public class MyPagerAdapter extends PagerAdapter {
  private List viewlist;
  private Listtitle;
  public  MyPagerAdapter(List viewlist,Listtitle){
  this.viewlist=viewlist;
  this.title=title;
    }
    @Override

    public int getCount() {
        return viewlist.size();
    }
    @Override
    public boolean isViewFromObject(View view, Object object) {
        return view==object;
    }
    @Override
    public Object instantiateItem(ViewGroup container, int position) {
         container.addView(viewlist.get(position));
        return viewlist.get(position);
    }
    @Override
    public void destroyItem(ViewGroup container, int position, Object object) {
       container.removeView(viewlist.get(position));
    }
    @Override
    public CharSequence getPageTitle(int position) {
        return title.get(position);
    }
FragmentPagerAdapter，以Fragment（四个Fragment类）作为填充的数据适配器
课程Demo    //开发复杂的经常用到
public class MyFragmentPagerAdapter extends FragmentPagerAdapter{

   private ListfragList;
   private ListtitleList;
   public MyFragmentPagerAdapter(FragmentManager fm,List fragList,ListtitleList) {
      super(fm);
      this.fragList=fragList;
      this.titleList=titleList;
   }
   @Override
   public Fragment getItem(int arg0) {

      return fragList.get(arg0);
   }
   @Override
   public int getCount() {
      return fragList.size();
   }
   @Override
   public CharSequence getPageTitle(int position) {
      return titleList.get(position);
   }
}

FragmentStatePagerAdapter适配器多了一个创建和销毁的过程

public void destroyItem(ViewGroup container, int position, Object object) {
   super.destroyItem(container, position, object);
}

@Override
public Object instantiateItem(ViewGroup arg0, int arg1) {
   return super.instantiateItem(arg0, arg1);
}
4.设置监听器
 public class MainActivity extends FragmentActivity implements OnPageChangeListener{
 private ViewPager pager;private ListviewList;
 private ListtitleList;
 private PagerTabStrip tab;
 private ListfragList;

   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.main);
        View view1 = View.inflate(this, R.layout.view1, null);
        View view2 = View.inflate(this, R.layout.view2, null);
        View view3 = View.inflate(this, R.layout.view3, null);
        View view4 = View.inflate(this, R.layout.view4, null);
      viewList=new ArrayList();
      viewList.add(view1);
      viewList.add(view2);
      viewList.add(view3);
      viewList.add(view4);
      titleList=new ArrayList();
      titleList.add("第一页");
      titleList.add("第二页");
      titleList.add("第三页");
      titleList.add("第四页");
      tab=(PagerTabStrip) findViewById(R.id.tab);
      //设置背景颜色
      tab.setBackgroundColor(Color.YELLOW);
      //设置短下划线颜色
      tab.setTabIndicatorColor(Color.BLUE);
     //设置是否隐藏下划细线
      tab.setDrawFullUnderline(false);
     //设置字体颜色
      tab.setTextColor(Color.RED);
      pager=(ViewPager) findViewById(R.id.pager);
      MyViewPagerAdapter adapter=new MyViewPagerAdapter(viewList, titleList);
      pager.setAdapter(adapter);
      fragList=new ArrayList();
      fragList.add(new Fragment1());
      fragList.add(new Fragment2());
      fragList.add(new Fragment3());
      fragList.add(new Fragment4());
//    MyFragmentPagerAdapter adapter2=new MyFragmentPagerAdapter(getSupportFragmentManager(), fragList, titleList);
//    pager.setAdapter(adapter2);
//    MyFragmentPagerAdapter2 adapter3=new MyFragmentPagerAdapter2(getSupportFragmentManager(), fragList, titleList);
//    pager.setAdapter(adapter3);    
      pager.setOnPageChangeListener(this);
   }
   @Override
   public void onPageScrollStateChanged(int arg0) {
      // TODO Auto-generated method stub
   }
   @Override
   public void onPageScrolled(int arg0, float arg1, int arg2) {
      // TODO Auto-generated method stub
   }
   @Override
   public void onPageSelected(int arg0) {
      // TODO Auto-generated method stub
      Toast.makeText(this, "这是第"+(arg0+1)+"个界面", Toast.LENGTH_SHORT).show();
   }
}

ViewFlipper用法：
加载的资源一般为ImageView
