android中怎么实现轮播图,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;

ListviewList;

PagerTabStrip pts;

ArrayListarrayList_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();

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= newPagerAdapter() {

@Overridepublic intgetCount() {

returnviewList.size();}

@Overridepublic booleanisViewFromObject(Viewview,Objectobject) {

returnview == object;}

@OverridepublicObjectinstantiateItem(ViewGroupcontainer,intposition) {

container.addView(viewList.get(position));returnviewList.get(position);

}

@Override

public void

destroyItem(

ViewGroupcontainer

,

intposition

,

Objectobject) {

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
