Android录制声音文件（音频）并播放

本文实例为大家分享了Android录制音频文件的具体代码，供大家参考，具体内容如下

1、这个demo中没有对多次点击同一个声音文件做详细处理，偶尔会有崩溃，用的时候需要注意。

2、按住录音按钮录音过程中，只对竖直方向处理了一下，水平方向没写；

3、没有做删除某个声音文件的操作，但是测试的时候实现了功能，需要用到的话，在MainActivity—>onItemClick中的TODO中有详细说明；

4、这只是个demo，如果要在项目中使用，先写出demo，没问题了，再引入项目，在写成demo后，在真机上运行的时候，如果出现获取录音权限，最好选择“允许”，如果拒绝，可能会崩溃。

记得打开手机运行录音的权限

先来效果图：

目录结构：

1、添加权限：

 <uses-permission android:name="android.permission.RECORD_AUDIO"/>
 <uses-permission android:name="android.permission.WAKE_LOCK"/>
 <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS"/>
 <uses-permission android:name="android.permission.VIBRATE"/>
 <uses-permission android:name="android.permission.WRITE_SETTINGS"/>
 <uses-permission android:name="android.permission.INTERACT_ACROSS_USERS_FULL"/>
 <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>
 <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
 <uses-permission android:name="android.permission.CALL_PHONE"/>
 <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
 <uses-permission android:name="android.permission.INTERNET" />
 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
 <uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" />

2、新建MediaRecorderUtils，复制以下源码：

package com.chen.voicedemo;

import android.media.MediaRecorder;
import android.os.Handler;
import android.util.Log;
import android.widget.ImageView;

import java.io.File;

/**

  */

  if (mediaRecorderUtils == null) {
   mediaRecorderUtils = new MediaRecorderUtils();
  }
  mimageView = imageView;
  return mediaRecorderUtils;
 }

  // 设置MediaRecorder录制音频的编码为amr.
  File file = new File(Utils.IMAGE_SDCARD_MADER);
  if (!file.exists()) {
   file.mkdirs();
  }
  path = Utils.IMAGE_SDCARD_MADER + Utils.getVoiceFileName() + "stock.amr";
  recorder.setOutputFile(path);
  // 设置录制好的音频文件保存路径
  try {
   recorder.prepare();// 准备录制
  } catch (Exception e) {
   e.printStackTrace();
  }
 }

 /**

  */
 public void MediaRecorderStart() {
  init();
  try {

   flag = true;
   if (mimageView != null) {
    updateMicStatus();
   }
  } catch (Exception e) {
   e.printStackTrace();
   Log.e("chen", "录制失败");
  }
 }

 /**

  */
 public void MediaRecorderStop() {
  try {
   recorder.stop();
   recorder.release(); //释放资源
   flag = false;
   mimageView = null;
   recorder = null;
  } catch (Exception e) {
   e.toString();
  }

 }

 /**
  * 删除已录制的音频
  */
 public void MediaRecorderDelete() {
  File file = new File(path);
  if (file.isFile()) {
   file.delete();
  }
  file.exists();
 }

 ;

 private final Handler mHandler = new Handler();
 private Runnable mUpdateMicStatusTimer = new Runnable() {
  public void run() {
   updateMicStatus();
  }
 };
 private int BASE = 1;
 private int SPACE = 1000;// 间隔取样时间
 private boolean flag = true;

 /**
  * 更新话筒状态
  */
 private void updateMicStatus() {
  if (recorder != null) {
   double ratio = (double) recorder.getMaxAmplitude() / BASE;
   double db = 0;// 分贝
   if (ratio > 1) {
    db = 20 * Math.log10(ratio);
   }
   int i = (int) db / 10;
   switch (i) {
    case 1:
     mimageView.setImageResource(R.drawable.rc_ic_volume_1);
     break;
    case 2:
     mimageView.setImageResource(R.drawable.rc_ic_volume_2);
     break;
    case 3:
     mimageView.setImageResource(R.drawable.rc_ic_volume_3);
     break;
    case 4:
     mimageView.setImageResource(R.drawable.rc_ic_volume_4);
     break;
    case 5:
     mimageView.setImageResource(R.drawable.rc_ic_volume_5);
     break;
    case 6:
     mimageView.setImageResource(R.drawable.rc_ic_volume_6);
     break;
    case 7:
     mimageView.setImageResource(R.drawable.rc_ic_volume_7);
     break;
    case 8:
     mimageView.setImageResource(R.drawable.rc_ic_volume_8);
     break;
   }
   if (flag) {
    mHandler.postDelayed(mUpdateMicStatusTimer, SPACE);
   }
  }
 }

}

3、创建MyChronometer，复制以下代码

package com.chen.voicedemo;

  updateText(SystemClock.elapsedRealtime());
 }

 /**

  *
  * @param listener The listener.
  */
 public void setOnMyChronometerTickListener(OnMyChronometerTickListener listener) {
  mOnMyChronometerTickListener = listener;
 }

 public void setOnMyChronometerTimeListener(OnMyChronometerTimeListener listener) {

  */
 public void stop() {
  mStarted = false;
  updateRunning();
  now_time /= 10;
  if (OnMyChronometerTimeListener != null) {

  }
 }

 @Override

4、创建工具类

package com.chen.voicedemo;

import android.Manifest;
import android.content.Context;
import android.content.pm.PackageManager;

  */
 public static boolean checkVoice(Context context) {

    return false;
   } else {
    return true;
   }
  } catch (Exception e) {
   return true;
  }

 }

 private static Toast toast;

 /**
  * 单例吐司
  */
 public static void showToast(Context context, String msg) {
  if (toast == null) {
   toast = Toast.makeText(context, msg, Toast.LENGTH_SHORT);
  }
  toast.setText(msg);
  toast.show();
 }

 /**
  * 获取指定文件夹下的所有文件路径
  *
  * @param root 指定文件夹路径

  */
 public static ArrayList<String> getVideoFiles(String root) {
  if (root == null || root == "")
   return null;

  ArrayList<String> list = new ArrayList<>();
  File file = new File(root);
  File[] fileList = file.listFiles();

  for (File f : fileList) {
   list.add(f.getPath());
  }

  return list;
 }

 /**

  *
  * @return 假如当前录制声音时间是2016年4月29号14点30分30秒。得到的文件名字就是20160429143030.这样保证文件名的唯一性
  */
 public static String getVoiceFileName() {
  long getNowTimeLong = System.currentTimeMillis();
  SimpleDateFormat time = new SimpleDateFormat("yyyyMMddHHmmss");
  String result = time.format(getNowTimeLong);
  return result;
 }

}

6、activity_main布局

   android:layout_marginRight="20dp"
   android:layout_toLeftOf="@id/stop_show_voice"
   android:background="#00ff00"
   android:padding="10dp"
   android:text="列表"
   android:textColor="#000000"
   android:textSize="20sp"
   />

 </RelativeLayout>

 <TextView
  android:id="@+id/voice"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:layout_gravity="center_horizontal"
  android:background="#00ff00"
  android:padding="10dp"
  android:text="开始录音"
  android:textColor="#000000"
  android:textSize="25sp"/>
</LinearLayout>

7、voice_popupwindow布局代码：录音的时候，会出现以下图片中的popupwindow

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

 <LinearLayout
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:layout_centerInParent="true"
  android:background="@android:color/black"
  android:orientation="vertical"
  android:paddingBottom="40dip"
  android:paddingLeft="60dip"
  android:paddingRight="60dip"
  android:paddingTop="40dip">

  <ImageView
   android:id="@+id/voice_shengyin"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:layout_gravity="center_horizontal"
   android:src="@drawable/rc_ic_volume_1"/>

  <com.chen.voicedemo.MyChronometer
   android:id="@+id/mychronometer"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:layout_centerHorizontal="true"
   android:layout_gravity="center_horizontal"
   android:textColor="@android:color/white"/>

 </LinearLayout>
</RelativeLayout>

8、还有一个动画布局，播放声音的时候，有个动画效果

<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/volume_animation"
    android:oneshot="false" >

 <item
  android:drawable="@drawable/rc_ic_voice_receive_play1"
  android:duration="100"/>
 <item
  android:drawable="@drawable/rc_ic_voice_receive_play2"
  android:duration="200"/>
 <item
  android:drawable="@drawable/rc_ic_voice_receive_play3"
  android:duration="300"/>

</animation-list>
