轮播图简单实现方式RollPagerView

android图片轮播效果，RollViewPager的简单使用

 <com.jude.rollviewpager.RollPagerView
            android:id="@+id/mViewPager"
            android:layout_width="match_parent"
            android:layout_height="170dp"
            app:rollviewpager_play_delay="3000" />

 

 

   在build.gradle（app）加载包

compile 'com.jude:rollviewpager:1.2.9'  

 实现代码：

 //广告轮播
 mViewPager = (RollPagerView) ItemView.findViewById(R.id.mViewPager);       
 mViewPager.setAdapter(new ImageLoopAdapter(getActivity(), mViewPager));

 ImageLoopAdapter.java

public class ImageLoopAdapter extends LoopPagerAdapter {

    String[] imgs = new String[0];
    private Context mContext;
    public ImageLoopAdapter(Context mContext,RollPagerView viewPager) {
        super(viewPager);

        this.mContext = mContext;
    }

    @Override
    public View getView(ViewGroup container, int position) {
        ImageView view = new ImageView(container.getContext());
        view.setScaleType(ImageView.ScaleType.CENTER_CROP);
        view.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
        Glide.with(mContext).load(Constants.URL[position]).into(view);

        return view;
    }

    @Override
    public int getRealCount() {
        return Constants.URL.length;
    }
}

 添加图片数据源：

这里可以自己设定

public class   Constants {

    public static String[] URL = {
            "http://cdn-l.llsapp.com/connett/c3115411-3669-466d-8ef2-e6c42c690303",
            "http://7xjww9.com1.z0.glb.clouddn.com/Hopetoun_falls.jpg",
            "http://cdn.llsapp.com/crm_test_1449051526097.jpg",
    };
