实现录音，播放，以及Socket的上传和下载。。【处女作】

近期因为工作的原因，写了一个如题的测试例子，本人从事android时间有限，请各位慢点拍砖、、

主程序如下:

其中用到的一个辅助类：

package com.kingtone.www.record.util;import java.io.File;import android.app.Activity;import android.os.Environment;import android.widget.Toast;/*** * @author YuanLiangFeng 袁良锋* at 2011-03-1** 该类为 硬件检测的 公共类*/public class EnvironmentShare {// 存放录音文件夹的名称static String AUDIO_RECORD = "/AudioRecord";// 存放下载而来的录音文件夹名称static String DOWNLOAD_AUDIO_RECORD = "/AudioRecord/downLoad";/*** 检测当前设备SD是否可用* * @return 返回"true"表示可用，否则不可用*/public static boolean haveSdCard(){return Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED) ;}/*** 获得SD卡根目录路径 * * @return String类型 SD卡根目录路径*/public static String getSdCardAbsolutePath(){return Environment.getExternalStorageDirectory().getAbsolutePath();}/*** 获得存储 录音文件的文件夹* * @return File类型 * 存储 录音文件的文件夹*/public static File getAudioRecordDir(){File audioRecordFile = new File(EnvironmentShare.getSdCardAbsolutePath() + AUDIO_RECORD);if (!audioRecordFile.exists()) {// 此处可能会创建失败，暂不考虑audioRecordFile.mkdir();}return audioRecordFile;}/*** 获得存储 下载而来的录音文件的文件夹* * @return File类型 * 存储 下载而来的 录音文件的文件夹*/public static File getDownAudioRecordDir(){File audioRecordFile = new File(EnvironmentShare.getSdCardAbsolutePath() + DOWNLOAD_AUDIO_RECORD);if (!audioRecordFile.exists()) {// 此处可能会创建失败，暂不考虑audioRecordFile.mkdir();}return audioRecordFile;}/*** 用Toast显示指定信息* * @param activity Activity类型 要显示提示信息的页面上下文* @param message String类型 将显示的提示信息内容* @param isLong boolean类型 如果为"true"表示长时间显示，否则为短时间显示*/public static void showToast(Activity activity,String message,boolean isLong){if (message == null ||message.equals("")) return ;int showTime = Toast.LENGTH_SHORT;if (isLong) {showTime = Toast.LENGTH_LONG;}Toast.makeText(activity, message, showTime).show();}/*** 用Toast显示指定信息 并设置标题显示 信息* * @param activity Activity类型 要显示提示信息的页面上下文* @param message String类型 将显示的提示信息内容* @param isLong boolean类型 如果为"true"表示长时间显示，否则为短时间显示*/public static void showToastAndTitle(Activity activity,String message,boolean isLong){activity.setTitle(message);showToast(activity, message, isLong);}}

main.xml 配置如下:

<?xml version="1.0" encoding="utf-8"?>

AndroidManifest.xml 配置如下：

<?xml version="1.0" encoding="utf-8"?>

服务端的代码放到附件里吧，要不然文章太长了、
