        android:layout_height="140dp"
        app:bvIsShowPointer="true"
        app:bvPageChangeDuration="800"
        app:bvPointerPlayInterval="2000"
        app:bvPointerAutoPlayAble="true"
        app:bvPointerContainerHeight="20dp"
        app:bvPointerGravity="right|bottom"
        app:bvPointerSpacing="8dp"/>

3.在 Activity 或者 Fragment

 bannerView.setAdapter(new BannerView.Adapter() {

            @Override
            public View initView(Context context) {
                ImageView imageView = new ImageView(context);
                return imageView;
            }

            @Override
            public int getCount() {
                return picUrls.size();
            }

            @Override
            public void bindView(View view, final int pos) {
                ImageView imageView = (ImageView) view;
                String url = picUrls.get(pos);
                Glide
                        .with(MainActivity.this)
                        .load(url)
                        .centerCrop()
                        .placeholder(R.mipmap.ic_launcher)
                        .crossFade()
                        .into(imageView);
                imageView.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        Log.w("@@@@ L63", "MainActivity:onClick() -> " + "pos = " + pos);
                    }
                });
            }

            @Override
            public boolean isSameType() {
                return true;
            }
        });
