很多网友不知道怎么获取图片路径，这里贴出来：

String path = Bimp.tempSelectBitmap.get(position).getImagePath();

补充：

通过GridView仿微信动态添加本地图片

此篇文章主要讲述GridView控件实现添加本地图片并显示.主要是关于GridView控件的基本操作,通常可以通过自定义继承BaseAdapter的适配器加载图片,而下面讲述的不是自定义的适配器,而是调用SimpleAdapter实现的.至于上传发布与网络交互此处不讲述,后面文章会讲!

一. 实现效果

    主要是通过点击+从本地相册中添加图片,同时显示图片至GridView.点击图片可以进行删除操作,同时界面中的发布EditView控件也很好看,不足之处在于+好没有移动至最后,但原理相同.

      

二. 项目工程结构

三. 界面布局详细代码
