基于Android的拍照上传程序开发

大家好，我是PETER(cfwdl)。写这篇文章是为了帮助以前没有没有接触过anroid或是刚刚入门并没有摸过手机的硬件设备监测、使用等功能的朋友，给大家一个我自己的写的心得和经验，我也是新手，所以大家互相交换一下经验吧。当然每个程序都会有问题，因为我不是最终用户，软件的测试工作没有好好测试过，大家凑合看看吧~！

程序介绍：

本程序主要完成一个煎蛋的android手机拍照程序(本程序的拍照功能比较简单，没有添加处理图像、手机自动对焦等功能，如果有需要的朋友可以自行参考一下相关linstener或action的资料)

主功能：手机拍照、拍照预览、图片的存储、图片资料编辑、图像上传等功能

其他相关需求：监测手机网络状态、监测手机GPS状态、获取GPS位置、获取基站位置等。

需求分析：

(程序流程)

正如上图所示，我大致的画了一下这个程序的简单的工作流程。

那么，各位看官们，现在开始我们的程序开发之旅吧。

程序设计：

PS:本人不是美工，所以界面肯定灰常粗糙，不过不影响我们展示功能~！大家权且凑合继续看

主界面(camera_surface.xml)：

本界面使用AbsoluteLayout布局来设计该界面，

下面的代码中我定义了一个全屏的SurfaceView用来在我们进入程序的第一个界面(就是拍照界面),

一个ID为nowLocality的TextView，来动态的刷新用户手机当前获取到的位置信息。

三个Button 分别是：拍照、上传、退出这个大概不用我再啰嗦了。

<?xml version="1.0" encoding="utf-8"?><AbsoluteLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="horizontal"><SurfaceView android:id="@+id/surface_camera" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="1"> </SurfaceView><TextView android:id="@+id/nowLocality"android:layout_x="10px"android:layout_y="25px"android:textColor="@color/red"android:textSize="14px"android:layout_width="wrap_content"android:layout_height="wrap_content"android:text="正在获取当前位置"/><Button android:text="拍照"android:layout_x="360px"android:layout_y="20px"android:drawableLeft="@drawable/ic_menu_camera"android:layout_width="wrap_content"android:layout_height="wrap_content"android:id="@+id/paizhao"/><Button android:text="上传"android:drawableLeft="@drawable/ic_menu_upload_mini"android:textSize="16px"android:layout_x="360px"android:layout_y="70px"android:layout_width="wrap_content"android:layout_height="wrap_content"android:id="@+id/uploadPhoto"/> <Button android:text="退出"android:textSize="16px"android:drawableLeft="@drawable/ic_menu_revert_mini"android:layout_x="360px"android:layout_y="120px"android:layout_width="wrap_content"android:layout_height="wrap_content"android:id="@+id/exitPro" /></AbsoluteLayout>

对应本界面的程序代码(MainPage.java)：

程序的相关部分我都已经添加了注释，大概的功能各位应该都可以看明白，流程就是按onCreate()里的顺序执行下来。
