viewpage轮播

    rg =(RadioGroup)findViewById(R.id.shouye_rg);
    //获取数据源
    init_images();

自定义适配器

public class Shouye_ViewPage_Adapter extends PagerAdapter {
    private List<ImageView> image;

    public Shouye_ViewPage_Adapter(List<ImageView> image) {
        super();
        this.image = image;
    }

    @Override
    public int getCount() {
        return Integer.MAX_VALUE;
    }

    @Override
    public boolean isViewFromObject(View view, Object object) {
        return view==object;
    }

    @Override
    public Object instantiateItem(ViewGroup container, int position) {
        container.addView(image.get(position%image.size()));
        return image.get(position%image.size());
    }

    @Override
    public void destroyItem(ViewGroup container, int position, Object object) {
        container.removeView(image.get(position%image.size()));
    }
}
