提要：需求是开发类似微信发语音的功能，没有语音转文字。网上看了一些代码，不能拿来直接用，部分代码逻辑有问题，所以想把自己的代码贴出来，仅供参考。

功能：

a、设置最大录音时长和录音倒计时（为了方便测试，最大时长设置为15秒，开始倒计时设置为7秒）

b、在录音之前检查录音和存储权限

源码：

1、录音对话框管理类DialogManager：

/** * 功能：录音对话框管理类 */public class DialogManager {  private AlertDialog.Builder builder;  private AlertDialog dialog;  private ImageVIEw mIcon;  private ImageVIEw mVoice;  private TextVIEw mLabel;  private Context context;  /**   * 构造方法   *   * @param context Activity级别的Context   */  public DialogManager(Context context) {    this.context = context;  }  /**   * 显示录音的对话框   */  public voID showRecordingDialog() {    builder = new AlertDialog.Builder(context,R.style.AudioRecorderDialogStyle);    LayoutInflater inflater = LayoutInflater.from(context);    VIEw vIEw = inflater.inflate(R.layout.audio_recorder_dialog,null);    mIcon = vIEw.findVIEwByID(R.ID.iv_dialog_icon);    mVoice = vIEw.findVIEwByID(R.ID.iv_dialog_voice);    mLabel = vIEw.findVIEwByID(R.ID.tv_dialog_label);    builder.setVIEw(vIEw);    dialog = builder.create();    dialog.show();    dialog.setCanceledOntouchOutsIDe(false);  }  /**   * 正在播放时的状态   */  public voID recording() {    if (dialog != null && dialog.isShowing()) { //显示状态      mIcon.setVisibility(VIEw.VISIBLE);      mVoice.setVisibility(VIEw.VISIBLE);      mLabel.setVisibility(VIEw.VISIBLE);      mIcon.setimageResource(R.drawable.ic_audio_recorder);      mVoice.setimageResource(R.drawable.ic_audio_v1);      mLabel.setText(R.string.audio_record_dialog_up_to_cancel);    }  }  /**   * 显示想取消的对话框   */  public voID wantToCancel() {    if (dialog != null && dialog.isShowing()) { //显示状态      mIcon.setVisibility(VIEw.VISIBLE);      mVoice.setVisibility(VIEw.GONE);      mLabel.setVisibility(VIEw.VISIBLE);      mIcon.setimageResource(R.drawable.ic_audio_cancel);      mLabel.setText(R.string.audio_record_dialog_release_to_cancel);    }  }  /**   * 显示时间过短的对话框   */  public voID tooShort() {    if (dialog != null && dialog.isShowing()) { //显示状态      mIcon.setVisibility(VIEw.VISIBLE);      mVoice.setVisibility(VIEw.GONE);      mLabel.setVisibility(VIEw.VISIBLE);      mLabel.setText(R.string.audio_record_dialog_too_short);    }  }  // 显示取消的对话框  public voID dismissDialog() {    if (dialog != null && dialog.isShowing()) { //显示状态      dialog.dismiss();      dialog = null;    }  }  /**   * 显示更新音量级别的对话框   *   * @param level 1-7   */  public voID updateVoiceLevel(int level) {    if (dialog != null && dialog.isShowing()) { //显示状态      mIcon.setVisibility(VIEw.VISIBLE);      mVoice.setVisibility(VIEw.VISIBLE);      mLabel.setVisibility(VIEw.VISIBLE);      int resID = context.getResources().getIDentifIEr("ic_audio_v" + level,"drawable",context.getPackagename());      mVoice.setimageResource(resID);    }  }  public voID updateTime(int time) {    if (dialog != null && dialog.isShowing()) { //显示状态      mIcon.setVisibility(VIEw.VISIBLE);      mVoice.setVisibility(VIEw.VISIBLE);      mLabel.setVisibility(VIEw.VISIBLE);      mLabel.setText(time + "s");    }  }}

2、录音管理类AudioManager

 /** * 功能：录音管理类 */public class AudioManager {  private MediaRecorder mMediaRecorder;  private String mDir;  private String mCurrentfilePath;  private static AudioManager mInstance;  private boolean isPrepared;  private AudioManager(String dir) {    this.mDir = dir;  }  //单例模式：在这里实例化AudioManager并传入录音文件地址  public static AudioManager getInstance(String dir) {    if (mInstance == null) {      synchronized (AudioManager.class) {        if (mInstance == null) {          mInstance = new AudioManager(dir);        }      }    }    return mInstance;  }  /**   * 回调准备完毕   */  public interface AudioStateListener {    voID wellPrepared();  }  public AudioStateListener mListener;  /**   * 回调方法   */  public voID setonAudioStateListener(AudioStateListener Listener) {    mListener = Listener;  }  /**   * 准备   */  public voID prepareAudio() {    try {      isPrepared = false;      file dir = fileUtils.createNewfile(mDir);      String filename = generatefilename();      file file = new file(dir,filename);      mCurrentfilePath = file.getabsolutePath();      Logger.t("AudioManager").i("audio file name :" + mCurrentfilePath);      mMediaRecorder = new MediaRecorder();      //设置输出文件      mMediaRecorder.setoutputfile(mCurrentfilePath);      //设置MediaRecorder的音频源为麦克风      mMediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);      //设置音频格式      mMediaRecorder.setoutputFormat(MediaRecorder.OutputFormat.MPEG_4);      //设置音频的格式为AAC      mMediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AAC);      //准备录音      mMediaRecorder.prepare();      //开始      mMediaRecorder.start();      //准备结束      isPrepared = true;      if (mListener != null) {        mListener.wellPrepared();      }    } catch (Exception e) {      e.printstacktrace();    }  }  /**   * 随机生成文件的名称   */  private String generatefilename() {    return UUID.randomUUID().toString() + ".m4a";  }  public int getVoiceLevel(int maxLevel) {    if (isPrepared) {      try {        //获得最大的振幅getMaxAmplitude() 1-32767        return maxLevel * mMediaRecorder.getMaxAmplitude() / 32768 + 1;      } catch (Exception e) {      }    }    return 1;  }  /**   * 释放资源   */  public voID release() {    if (mMediaRecorder != null) {      mMediaRecorder.stop();      mMediaRecorder.release();      mMediaRecorder = null;    }  }  public voID cancel() {    release();    if (mCurrentfilePath != null) {      file file = new file(mCurrentfilePath);      fileUtils.deletefile(file);      mCurrentfilePath = null;    }  }  public String getCurrentfilePath() {    return mCurrentfilePath;  }}

3、自定义录音按钮AudioRecorderbutton

/** * 功能：录音按钮 */public class AudioRecorderbutton extends AppCompatbutton {  private Context mContext;  //取消录音Y轴位移  private static final int disTANCE_Y_CANCEL = 80;  //录音最大时长限制  private static final int AUdio_RECORDER_MAX_TIME = 15;

 public AudioRecorderbutton(Context context) {    this(context,null);  }  public AudioRecorderbutton(Context context,AttributeSet attrs) {    super(context,attrs);    this.mContext = context;    mDialogManager = new DialogManager(context);    audioManager = (androID.media.AudioManager) context.getSystemService(Context.AUdio_SERVICE);    String dir = SdUtils.getCustomFolder("Audios");//创建文件夹    mAudioManager = AudioManager.getInstance(dir);    mAudioManager.setonAudioStateListener(new AudioManager.AudioStateListener() {      @OverrIDe      public voID wellPrepared() {        mHandler.sendEmptyMessage(MSG_AUdio_PREPARED);      }    });    //按钮长按 准备录音 包括start    setonLongClickListener(new OnLongClickListener() {      @OverrIDe      public boolean onLongClick(VIEw v) {        //先判断有没有录音和存储权限，有则开始录音，没有就申请权限        int hasAudioPermission = ContextCompat.checkSelfPermission(mContext,Manifest.permission.RECORD_AUdio);

         break;      }    }  }}

4、DialogStyle

<!--App Base theme--><style name="AppthemeParent" parent="theme.AppCompat.light.NoActionbar">  <!--不显示状态栏：22之前-->  <item name="androID:windowNoTitle">true</item>  <item name="androID:windowAnimationStyle">@style/ActivityAnimtheme</item><!--Activity动画-->  <item name="actionOverflowMenuStyle">@style/MenuStyle</item><!--toolbar菜单样式--></style><!--Dialog式的Activity--><style name="ActivityDialogStyle" parent="AppthemeParent">  <item name="androID:windowBackground">@androID:color/transparent</item>  <!-- 浮于Activity之上 -->  <item name="androID:windowIsfloating">true</item>  <!-- 边框 -->  <item name="androID:windowFrame">@null</item>  <!-- Dialog以外的区域模糊效果 -->  <item name="androID:backgroundDimEnabled">true</item>  <!-- 半透明 -->  <item name="androID:windowIsTranslucent">true</item>  <!-- Dialog进入及退出动画 -->  <item name="androID:windowAnimationStyle">@style/ActivityDialogAnimation</item></style><!--Audio Recorder Dialog--><style name="AudioRecorderDialogStyle" parent="ActivityDialogStyle">  <!-- Dialog以外的区域模糊效果 -->  <item name="androID:backgroundDimEnabled">false</item></style><!-- Dialog动画：渐入渐出--><style name="ActivityDialogAnimation" parent="@androID:style/Animation.Dialog">  <item name="androID:windowEnteranimation">@anim/fade_in</item>  <item name="androID:windowExitAnimation">@anim/fade_out</item></style>

5、DialogLayout

<?xml version="1.0" enCoding="utf-8"?><linearLayout xmlns:androID="http://schemas.androID.com/apk/res/androID"  androID:layout_wIDth="wrap_content"  androID:layout_height="wrap_content"  androID:background="@drawable/audio_recorder_dialog_bg"  androID:gravity="center"  androID:orIEntation="vertical"  androID:padding="20dp">  <linearLayout    androID:layout_wIDth="wrap_content"    androID:layout_height="wrap_content"    androID:orIEntation="horizontal">    <ImageVIEw      androID:ID="@+ID/iv_dialog_icon"      androID:layout_wIDth="wrap_content"      androID:layout_height="wrap_content"      androID:src="@drawable/ic_audio_recorder" />    <ImageVIEw      androID:ID="@+ID/iv_dialog_voice"      androID:layout_wIDth="wrap_content"      androID:layout_height="wrap_content"      androID:src="@drawable/ic_audio_v1" />  </linearLayout>  <TextVIEw    androID:ID="@+ID/tv_dialog_label"    androID:layout_wIDth="wrap_content"    androID:layout_height="wrap_content"    androID:layout_margintop="15dp"    androID:text="@string/audio_record_dialog_up_to_cancel"    androID:textcolor="@color/white"    androID:textSize="15dp" /></linearLayout>

6、用到的字符串

<!--AudioRecord--><string name="audio_record_button_normal">按住 说话</string><string name="audio_record_button_recording">松开 结束</string><string name="audio_record_button_cancel">松开手指 取消发送</string><string name="audio_record_dialog_up_to_cancel">手指上划，取消发送</string><string name="audio_record_dialog_release_to_cancel">松开手指，取消发送</string><string name="audio_record_dialog_too_short">录音时间过短</string>

7、使用：按钮的样式不需要写在自定义button中，方便使用

<com.kIDney.base_library.vIEw.audioRecorder.AudioRecorderbutton  androID:ID="@+ID/btn_audio_recorder"  androID:layout_wIDth="match_parent"  androID:layout_height="wrap_content"  androID:text="@string/audio_record_button_normal" /> AudioRecorderbutton audioRecorderbutton = findVIEwByID(R.ID.btn_audio_recorder); audioRecorderbutton.setAudioFinishRecorderListener(new AudioRecorderbutton.AudioFinishRecorderListener() {   @OverrIDe   public voID onFinish(float seconds,String filePath) {     Logger.i(seconds + "秒：" + filePath);   } });
