Android Banner自动轮播

上图

核心类:

public class BannerLayout extends RelativeLayout {

    private ViewPager pager;
    //指示器容器
    private LinearLayout indicatorContainer;

    private Drawable unSelectedDrawable;
    private Drawable selectedDrawable;

    private int WHAT_AUTO_PLAY = 1000;

    private boolean isAutoPlay = true;

    private int itemCount;

    private int selectedIndicatorColor = 0xffff0000;
    private int unSelectedIndicatorColor = 0x88888888;
    private Shape indicatorShape = Shape.oval;
    private int selectedIndicatorHeight = 6;
    private int selectedIndicatorWidth = 6;
    private int unSelectedIndicatorHeight = 6;
    private int unSelectedIndicatorWidth = 6;
    private Position indicatorPosition = Position.centerBottom;
    private int autoPlayDuration = 4000;
    private int scrollDuration = 900;
    private int indicatorSpace = 3;
    private int indicatorMargin = 10;
    private int currentPosition;
    private ImageLoader imageLoader;

    private enum Shape {
        rect, oval
    }
    private enum Position {
        centerBottom,
        rightBottom,
        leftBottom,
        centerTop,
        rightTop,
        leftTop
    }

    @Override
    protected void onAttachedToWindow() {
        super.onAttachedToWindow();
        startAutoPlay();
    }

    @Override
    protected void onDetachedFromWindow() {
        super.onDetachedFromWindow();
        stopAutoPlay();
    }

    private OnBannerItemClickListener onBannerItemClickListener;

    private Handler handler = new Handler(new Handler.Callback() {
        @Override
        public boolean handleMessage(Message msg) {
            if (msg.what == WHAT_AUTO_PLAY) {
                if (pager != null && isAutoPlay) {
                    pager.setCurrentItem(pager.getCurrentItem() + 1, true);
                    handler.sendEmptyMessageDelayed(WHAT_AUTO_PLAY, autoPlayDuration);
                }
            }
            return false;
        }
    });

    public BannerLayout(Context context) {
        this(context, null);
    }

完全封装框架一句话搞定
