Android录制声音文件（音频），并播放

readme：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;/** * 录音工具类 */public class MediaRecorderUtils {    private static MediaRecorder recorder;    static MediaRecorderUtils mediaRecorderUtils;    static ImageView mimageView;    private String path;    /**     * 获得单例对象，传入一个显示音量大小的imageview对象，如不需要显示可以传null     */    public static MediaRecorderUtils getInstence(ImageView imageView) {        if (mediaRecorderUtils == null) {            mediaRecorderUtils = new MediaRecorderUtils();        }        mimageView = imageView;        return mediaRecorderUtils;    }    /**     * 获得音频路径     */    public String getPath() {        return path;    }    /**     * 初始化     */    private void init() {        recorder = new MediaRecorder();// new出MediaRecorder对象        recorder.setAudioSource(MediaRecorder.AudioSource.MIC);        // 设置MediaRecorder的音频源为麦克风          recorder.setOutputFormat(MediaRecorder.OutputFormat.RAW_AMR);        // 设置MediaRecorder录制的音频格式          recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);        // 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();        }    }    /**     * 开始录音     */    public void MediaRecorderStart() {        init();        try {            recorder.start();            flag = true;            if (mimageView != null) {                updateMicStatus();            }        } catch (Exception e) {            e.printStackTrace();            Log.e("chen", "录制失败");        }    }    /**     * 停止录音     */    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;import android.annotation.SuppressLint;import android.content.Context;import android.os.Handler;import android.os.Message;import android.os.SystemClock;import android.util.AttributeSet;import android.view.accessibility.AccessibilityEvent;import android.view.accessibility.AccessibilityNodeInfo;import android.widget.TextView;public class MyChronometer extends TextView {    private static final String TAG = "MyChronometer";    /**     * A callback that notifies when the MyChronometer has incremented on its     * own.     */    public interface OnMyChronometerTickListener {        /**         * Notification that the MyChronometer has changed.         */        void onMyChronometerTick(int time);    }    public interface OnMyChronometerTimeListener {        /**         * Notification that the MyChronometer has changed.         */        void OnMyChronometerTimeListener(int time);    }    private OnMyChronometerTimeListener OnMyChronometerTimeListener;    private long mBase;    private boolean mVisible;    private boolean mStarted;    private boolean mRunning;    private OnMyChronometerTickListener mOnMyChronometerTickListener;    private long now_time;    private static final int TICK_WHAT = 2;    /**     * Initialize this MyChronometer object.

This does not affect the base as set from     * {@link #setBase}, just the view display.     * <p/>     * This stops the messages to the handler, effectively releasing resources     * that would be held as the MyChronometer is running, via {@link #start}.     */    public void stop() {        mStarted = false;        updateRunning();        now_time /= 10;        if (OnMyChronometerTimeListener != null) {            OnMyChronometerTimeListener.OnMyChronometerTimeListener((int) now_time);        }    }    @Override    protected void onDetachedFromWindow() {        super.onDetachedFromWindow();        mVisible = false;        updateRunning();    }    @Override    protected void onWindowVisibilityChanged(int visibility) {        super.onWindowVisibilityChanged(visibility);        mVisible = visibility == VISIBLE;        updateRunning();    }    private synchronized void updateText(long now) {        long seconds = now - mBase;        seconds /= 10;        now_time = seconds;        int time_m = (int) (seconds / 100);        if (mOnMyChronometerTickListener != null) {            mOnMyChronometerTickListener.onMyChronometerTick(time_m);        }        int time_s = (int) (seconds % 100);        setText(time_m + "");    }    private void updateRunning() {        boolean running = mVisible && mStarted;        if (running != mRunning) {            if (running) {                updateText(SystemClock.elapsedRealtime());                mHandler.sendMessageDelayed(Message.obtain(mHandler, TICK_WHAT), 1000);            } else {                mHandler.removeMessages(TICK_WHAT);            }            mRunning = running;        }    }    private Handler mHandler = new Handler() {        public void handleMessage(Message m) {            if (mRunning) {                updateText(SystemClock.elapsedRealtime());                sendMessageDelayed(Message.obtain(this, TICK_WHAT), 1000);            }        }    };    @SuppressLint("NewApi")    @Override    public void onInitializeAccessibilityEvent(AccessibilityEvent event) {        super.onInitializeAccessibilityEvent(event);        event.setClassName(MyChronometer.class.getName());    }    @SuppressLint("NewApi")    @Override    public void onInitializeAccessibilityNodeInfo(AccessibilityNodeInfo info) {        super.onInitializeAccessibilityNodeInfo(info);        info.setClassName(MyChronometer.class.getName());    }}

4、创建工具类

package com.chen.voicedemo;import android.Manifest;import android.content.Context;import android.content.pm.PackageManager;import android.os.Environment;import android.support.v4.content.ContextCompat;import android.widget.Toast;import java.io.File;import java.text.SimpleDateFormat;import java.util.ArrayList;/** * 工具 */public class Utils {    /**     * SD卡下语音目录     */    public static final String IMAGE_SDCARD_MADER = Environment            .getExternalStorageDirectory()            + "/chen/voice/";    /**     * 检查录音权限6.0     */    public static boolean checkVoice(Context context) {        try {            if (ContextCompat.checkSelfPermission(context, Manifest.permission.RECORD_AUDIO) != PackageManager.PERMISSION_GRANTED) {                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     * @return 指定文件夹下的所有文件     */    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;    }    /**     * 获取声音文件名字     *     * @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;    }}

5、MainActivity

package com.chen.voicedemo;import android.app.Activity;import android.graphics.drawable.AnimationDrawable;import android.graphics.drawable.ColorDrawable;import android.media.MediaPlayer;import android.os.Bundle;import android.os.SystemClock;import android.util.Log;import android.view.LayoutInflater;import android.view.MotionEvent;import android.view.View;import android.view.ViewGroup;import android.view.Window;import android.view.WindowManager;import android.widget.AdapterView;import android.widget.BaseAdapter;import android.widget.ImageView;import android.widget.ListView;import android.widget.PopupWindow;import android.widget.TextView;import java.io.File;import java.util.ArrayList;import java.util.List;public class MainActivity extends Activity implements View.OnTouchListener, AdapterView.OnItemClickListener {    /**     * 开始录音按钮     */    private TextView voice;

           }        } else {            Utils.showToast(this, "录音时间太短");        }    }}

6、activity_main布局

<?xml version="1.0" encoding="utf-8"?><LinearLayout    xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical"    >    <TextView        android:id="@+id/voice_popup"        android:layout_width="match_parent"        android:layout_height="1dip"/>    <ListView        android:id="@+id/show_voices"        android:layout_width="match_parent"        android:layout_height="0dp"        android:layout_weight="1"/>    <RelativeLayout        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:orientation="horizontal">        <ImageView            android:id="@+id/voice_anim"            android:layout_width="60dp"            android:layout_height="30dp"            android:layout_centerVertical="true"            android:layout_marginLeft="30dp"            android:background="#00ff00"/>        <TextView            android:id="@+id/stop_show_voice"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_alignParentRight="true"            android:layout_centerVertical="true"            android:layout_gravity="center_horizontal"            android:layout_marginBottom="20dp"            android:layout_marginRight="20dp"            android:background="#00ff00"            android:padding="10dp"            android:text="停止播放"            android:textColor="#000000"            android:textSize="20sp"            />        <TextView            android:id="@+id/show_voice_list"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_centerVertical="true"            android:layout_gravity="center_horizontal"            android:layout_marginBottom="20dp"            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>
