利用AbSlidingPlayView做一個廣告輪播效果

AbSlidingPlayView是AndBase框架中的功能之一，今天就來嘗試用AbSlidingPlayView來做一個好多類新聞app都會涉及到的，廣播輪播效果，能和viewpager一樣實現滑動，並且帶有各種監聽事件

下面先貼出AbSlidingPlayView類的源碼，基本只要復制黏貼到項目中去即可

代碼很長，裡面有各種注釋，就不多說了，可以仔細研究一下裡面的源碼，可以對輪播效果進行各種控制，比如翻頁的快慢，翻頁的時長等等

在這裡還需要用到一些其他的接口類，這裡就不貼出來了，後面會貼出demo的下載地址，

接下來我們寫一個布局文件，很簡單，直接上代碼

就只有一個自定義的控件。
接下來上主Activity的代碼：

                        mSlidingPlayView.clearChildFocus(mSlidingPlayView.getFocusedChild());


                    }
                });
                //mSlidingPlayView的滑動的監聽事件 
                mSlidingPlayView.setOnPageChangeListener(new AbOnChangeListener() {
                    @Override
                    public void onChange(int position) {

                    }
                });
                //對list進行循環
               for(int i=0;i
裡面有各種接口和監聽事件，是不是很簡單！
