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

      

二. 项目工程结构

三. 界面布局详细代码

    1.主界面activity_main.xml
    主要通过相对布局实现,第一部分是底部的TextView,中间是EditView和GridView相对布局,下面是两个按钮.同时EditView调用res/drawable-hdpi中的editview_shape.xml,GridView显示的每张图片通过griditem_addpic.xml实现.

173.         builder.create().show();  
174.     }  
175.   
176. }  

    同时需要在AndroidMainfest.xml中添加权限操作SD卡和网络上传至服务器.

[html] view plaincopy

 

 

1. <!-- 申明网络权限  -->  
2. <uses-permission android:name="android.permission.INTERNET" />  
3. <!-- 申明权限 操作SD卡 -->    
4. <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />  

五. 总结

    

    该文章需要注意一个地方：在使用SimpleAdapter适配器加载bmp图片时,可能在GridView中不显示.即HashMap中map.put("itemImage",bmp)不显示图片,而使用put装入R.drawable.img却能显示.
    这时有两种解决方法,一种是自定义继承BaseAdapter的适配器实现;另一种方法则是如上所示通过ViewBinder()接口实现,感谢博主dmin_提供的方法.

Android图片上传，可以选择多张图片，缩放预览，拍照上传等
