自定义类SimpleImageBanner继承BaseIndicatorBanner

public class SimpleImageBanner extends BaseIndicatorBanner {
    private ColorDrawable colorDrawable;

    public SimpleImageBanner(Context context) {

        this(context,null,0);
    }

    public SimpleImageBanner(Context context, AttributeSet attrs) {
        this(context, attrs, 0);
    }

    public SimpleImageBanner(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        colorDrawable = new ColorDrawable(Color.parseColor("#555555"));
    }

    @Override
    public void onTitleSlect(TextView tv, int position) {
        BannerItem bannerItem=mDatas.get(position);
        tv.setText(bannerItem.title);
    }

    @Override
    public View onCreateItemView(int position) {
        View inflate = View.inflate(mContext, R.layout.layout_banner, null);
        ImageView imageView = ViewFindUtils.find(inflate, R.id.iv);
        Log.i("bannerItem.title", "bannerItem.title: "+imageView);
        BannerItem bannerItem=mDatas.get(position);
        int itemWidth=mDisplayMetrics.widthPixels;
        int itemHight=(int) (itemWidth * 360 * 1.0f / 640);
        imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
        imageView.setLayoutParams(new LinearLayout.LayoutParams(itemWidth,itemHight));
        String imgUrl=bannerItem.imgUrl;
        if (!TextUtils.isEmpty(imgUrl)){         Glide.with(mContext).load(imgUrl).override(itemWidth,itemHight).centerCrop().placeholder(R.mipmap.ic_launcher).into(imageView);
        }else {
            imageView.setImageDrawable(colorDrawable);
        }

        return inflate;
    }
}

资源类DataProvider:

public class DataProvider {
    public static String[] titles = new String[]{
            "欢乐颂:五美破案总动员",
            "无心法师:生死离别!月牙遭虐杀",
            "花千骨:尊上沦为花千骨",
            "综艺饭:胖轩偷看夏天洗澡掀波澜",
            "碟中谍4:阿汤哥高塔命悬一线,超越不可能",
    };
    public static String[] urls = new String[]{//640*360 360/640=0.5625
            "http://r2.ykimg.com/050C0000571EB4F867BC3D14E908D907",//"欢乐颂:五美破案总动员"
            "http://photocdn.sohu.com/tvmobilemvms/20150907/144158380433341332.jpg",//无心法师:生死离别!月牙遭虐杀
            "http://photocdn.sohu.com/tvmobilemvms/20150907/144160286644953923.jpg",//花千骨:尊上沦为花千骨
            "http://photocdn.sohu.com/tvmobilemvms/20150902/144115156939164801.jpg",//综艺饭:胖轩偷看夏天洗澡掀波澜
            "http://photocdn.sohu.com/tvmobilemvms/20150907/144159406950245847.jpg",//碟中谍4:阿汤哥高塔命悬一线,超越不可能
    };
    public static ArrayList getList() {
        ArrayList list = new ArrayList<>();
        for (int i = 0; i < urls.length; i++) {
            BannerItem item = new BannerItem();
            item.imgUrl = urls[i];
            item.title = titles[i];
            list.add(item);
        }
        return list;
    }
}

findViewById帮助类ViewFindUtils:

public class ViewFindUtils
{
    /**
     * ViewHolder简洁写法,避免适配器中重复定义ViewHolder,减少代码量 用法:
     * 
     * 
     * if (convertView == null)
     * {
     *  convertView = View.inflate(context, R.layout.ad_demo, null);
     * }
     * TextView tv_demo = ViewHolderUtils.get(convertView, R.id.tv_demo);
     * ImageView iv_demo = ViewHolderUtils.get(convertView, R.id.iv_demo);
     * 
*/ public static T hold(View view, int id) { SparseArray viewHolder = (SparseArray) view.getTag(); if (viewHolder == null) { viewHolder = new SparseArray<>(); view.setTag(viewHolder); } View childView = viewHolder.get(id); if (childView == null) { childView = view.findViewById(id); viewHolder.put(id, childView); } return (T) childView; } /** * 替代findviewById方法 */ public static T find(View view, int id) { return (T) view.findViewById(id); } }

实体BannerItem:

public class BannerItem {
    public String imgUrl;
    public String title;
}

MainActivity:

public class MainActivity extends AppCompatActivity {
private ImageView imageView;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main_layout);
        SimpleImageBanner simpleImageBanner= (SimpleImageBanner) findViewById(R.id.ban);
        simpleImageBanner.setSource(DataProvider.getList()).startScroll();
        simpleImageBanner.setOnItemClickL(new BaseBanner.OnItemClickL() {
            @Override
            public void onItemClick(int position) {
                Toast.makeText(MainActivity.this,"position->"+position,Toast.LENGTH_SHORT).show();
            }
        });
    }
}
