Android中轮播图的实现

在Android中想要实现轮播图，会用到ViewPager和其子控件PagerTabStrip（标题栏）

怎么样一步一步的去做到:

1.将View视图添加到集合中

public class MyActivity extends Activity{    ViewPager viewPager;    View view_a,view_b,view_c;    List<View> viewList;    PagerTabStrip pts;    ArrayList<String>arrayList_pts;    Button button;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity);        pts = (PagerTabStrip) findViewById(R.id.pts);        pts.setBackgroundColor(Color.parseColor("#FF8EFF"));        pts.setTabIndicatorColor(Color.parseColor("#00FFFF"));        viewPager = (ViewPager) findViewById(R.id.vp_activity);        LayoutInflater inflater = LayoutInflater.from(this);viewList = new ArrayList<View>();viewList.add(view_a);viewList.add(view_b);viewList.add(view_c);arrayList_pts = new ArrayList<>();arrayList_pts.add("第一页");arrayList_pts.add("第二页");arrayList_pts.add("第三页");        view_a = inflater.inflate(R.layout.activity_one,null);        view_b = inflater.inflate(R.layout.activity_two,null);        view_c = inflater.inflate(R.layout.activity_three,null);

2.创建数据源Adapter，传入到集合，并且要实现其中的四个方法 

a. getCount() 获取数据源的大小 b. isViewFromObject()判断当前的View是否是对对象返回c. instantiateItem() 初始换页面  d. destroyItem()销毁页面

PagerAdapter pagerAdapter = new PagerAdapter() {    @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));   

 }

虽然很是粗糙，但是将就看看吧！ 下面是具体的实现效果
