mainActivity如下:

//笔记:
//利用ViewPager来实现一个应用程序的欢迎界面
//1 布局较简单.包含两个东西:ViewPager和几个小圆点的集合
//2 初始化所有用于展示的图片和所有的小圆点
//3 给ViewPager添加适配器并且对其滑动实现监听
//4 参考资料

		mImageView.setOnClickListener(new OnClickListener() {
			public void onClick(View v) {
				Toast.makeText(mContext, ""+mResoureId, Toast.LENGTH_SHORT).show();
			}
		});
	}

}
