simplebanner

原理

在adapter原来的数据的最前面插入最后面的元素，最后面同理，与viewpager那种size设置成无限相比，这样做性能相对更好，更节省内存。而size无限，单它的当前项为一个较大的数值，内部计算也会相应的增加计算压力。

    banner.resumeScroll();//回复
    banner.pauseScroll();//暂停
    
    banner.setInterval(5000);
    banner.setPageChangeDuration(500);
    banner.setBannerDataInit(new Banner.BannerDataInit<String>() {
        @Override
        public ImageView initImageView() {
            //设置图片加载的控件（如：Fresco 这里可以传入SimpleDraweeView）
             return (ImageView) getLayoutInflater().inflate(R.layout.imageview, null);
        }

        @Override
        public void initImgData(ImageView imageView, String imgPath) {
            //可在这里控制图片的加载，
            //ImageLoader.getInstance().displayImage(imgPath, imageView, options);
            //((SimpleDraweeView)imageView).setImageURI(Uri.parse(imgPath));
            }
        });
        banner.setDataSource(drawables);

        //----------------------indicator start------------------------------
        bannerIndicator = (BannerIndicator) findViewById(R.id.indicator);
        bannerIndicator.setIndicatorSource(
                ContextCompat.getDrawable(getBaseContext(), R.drawable.select_bg),//select
                ContextCompat.getDrawable(getBaseContext(), R.drawable.select_bg_no),//unselect
                50//widthAndHeight
        );
        banner.attachIndicator(bannerIndicator);
        //----------------------indicator end------------------------------

        banner.setOnBannerItemClickListener(new Banner.OnBannerItemClickListener() {
            @Override
            public void onItemClick(int position) {
                Toast.makeText(getBaseContext(), "position:" + position, Toast.LENGTH_SHORT).show();
