Android 轮番播放广告图片

项目中有很多需求是显示网络图片的，然后进行轮番播放，下面先贴上效果图片，看一下效果

有两种方式进行加载，一种是从网上直接下载图片并进行显示，另一种是加载res下的图片，直接进行显示，可以根据需求进行选择，下面上项目结构图片，是自定义的FrameLayout，然后直接在MainActivity中进行调用，

下面是代码，xml文件的代码就不上传了，很简单，稍后会把代码直接上传至网上，有需要的话可以直接下载即可

在MainActivity之中直接金鼎调用：：

<span style="font-size:18px;">myFrame.setImageRes(new int[] { R.drawable.image01, R.drawable.image02,R.drawable.image03, R.drawable.image04 });：</span>

或者：：：

<span style="font-size:18px;"> myFrame.setImageUrl(new String[] { "http://e.hiphotos.baidu.com/image/pic/item/b2de9c82d158ccbf0881c1d01dd8bc3eb135411e.jpg", "http://c.hiphotos.baidu.com/image/pic/item/0ff41bd5ad6eddc4c3dbc0113ddbb6fd5266331f.jpg", "http://h.hiphotos.baidu.com/image/pic/item/d058ccbf6c81800a7e38fce4b53533fa838b477e.jpg", "http://f.hiphotos.baidu.com/image/pic/item/adaf2edda3cc7cd9b87b41333d01213fb90e9181.jpg" });</span>
