代码是从聊天类项目中抽出来的，播放类中含有本地播放和网络播放，做法仿微信，先将网络路径中的.amr文件下载下来，然后存到本地播放。
一、录音类
import java.io.File;import java.io.IOException;import android.media.MediaRecorder;public class ChatRecorder { private String mOutputFileName = ""; private MediaRecorder mRecorder = null; private long mStartTime = 0L; private static ChatRecorder mChatRecorder = null; private ChatRecorder() {} public static ChatRecorder getInstance() { if (mChatRecorder == null) { synchronized (ChatRecorder.class) { if (mChatRecorder == null) { mChatRecorder = new ChatRecorder(); } } } return mChatRecorder; } public void initRecorder() { mRecorder = new MediaRecorder(); } public void startRecord(String outputFileName) { if (mRecorder == null) { return; } this.mOutputFileName = outputFileName; File parentFile = new File(outputFileName).getParentFile(); if (!parentFile.exists()) { parentFile.mkdirs(); } mRecorder.setAudioSource(MediaRecorder.AudioSource.MIC); mRecorder.setOutputFormat(MediaRecorder.OutputFormat.AMR_NB); mRecorder.setOutputFile(mOutputFileName); mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB); try { mRecorder.prepare(); } catch (IOException e) { e.printStackTrace(); } mRecorder.start(); mStartTime = System.currentTimeMillis(); } public long stopRecord() { if (mRecorder != null) { mRecorder.stop(); return System.currentTimeMillis() - mStartTime; } return 0L; } public void exitRecorder() { if (mRecorder != null) { mRecorder.release(); mRecorder = null; } } public String getOutputFileName() { return mOutputFileName; } public double getAmplitude() { if (mRecorder != null) { return (mRecorder.getMaxAmplitude() / 2700.0); } else { return 0; } }}二、播放类
