Android录制语音

Android

录音两个需要注意的地方，一是录音过短的时候会失败，所以要监听录音时间长短，小于一秒的时候就显示失败；二是录音的时候关闭其他声音

集成方法：

Step 1. Add the JitPack repository to your build file

  1. //Add it in your root build.gradle at the end of repositories:
  2. allprojects {
  3.         repositories {
  4.             ...
  5.             maven { url 'https://jitpack.io' }
  6.         }
  7.     }

Step 2. Add the dependency

  1. //Add the dependency
  2. dependencies {
  3.     implementation 'com.github.tyhjh:AudioRecording:v1.0.0'
  4. }

基本使用

  1. //设置录音保存位置
  2. AudioRecordUtil.init(Environment.getExternalStorageDirectory() + "/audio/");
  3. recordUtil = AudioRecordUtil.getInstance();
  4. //开始录音
  5. recordUtil.startRecord(MainActivity.this);
  6. //取消录音，时间太短须取消
  7. recordUtil.cancelRecord(MainActivity.this);
  8. //结束录音（保存录音文件）
  9. recordUtil.stopRecord(MainActivity.this);  
  10. //录音监听
  11.         AudioRecordUtil.getInstance().setOnAudioStatusUpdateListener(new AudioRecordUtil.OnAudioStatusUpdateListener() {
  12.             @Override
  13.             public void onUpdate(double db, long time) {
  14.                 //根据分贝值来设置录音时话筒图标的上下波动
  15.             }
  17.             @Override
  18.             public void onStop(final String filePath) {
  19.                 //获取录音文件
  20.             }
  21.         });

具体实现

录音时候关闭或开启其他声音

  1.     public static boolean muteAudioFocus(Context context, boolean bMute) {
  2.         if (context == null) {
  3.             Log.d("ANDROID_LAB", "context is null.");
  4.             return false;
  5.         }
  6.         boolean bool = false;
  7.         AudioManager am = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
  8.         //关闭声音
  9.         if (bMute) {
  10.             int result = am.requestAudioFocus(null, AudioManager.STREAM_MUSIC, AudioManager.AUDIOFOCUS_GAIN_TRANSIENT);
  11.             bool = result == AudioManager.AUDIOFOCUS_REQUEST_GRANTED;
  12.         } else {
  13.                 //恢复声音
  14.             int result = am.abandonAudioFocus(null);
  15.             bool = result == AudioManager.AUDIOFOCUS_REQUEST_GRANTED;
  16.         }
  17.         Log.d("ANDROID_LAB", "pauseMusic bMute=" + bMute + " result=" + bool);
  18.         return bool;
  19.     }

调用录音的类并实现其中的方法

关于录音的时候显示语音声音大小动画
一个ImageView，设置背景，显示动画

  2. <ImageView
  3.         android:id="@+id/zeffect_recordbutton_dialog_imageview"
  4.         android:layout_width="30dp"
  5.         android:layout_height="30dp"
  6.         android:src="@drawable/zeffect_recordbutton_micrphone" />

其中src也是一个xml文件,xml里面的drawable是两张颜色不一样形状一样的图片，我用的是矢量图片。

  1. <?xml version="1.0" encoding="utf-8"?>
  2. <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
  3.     <item
  4.         android:id="@android:id/background"
  5.         android:drawable="@drawable/ic_voice_null" />
  6.     <item android:id="@android:id/progress">
  7.         <clip
  8.             android:clipOrientation="vertical"
  9.             android:drawable="@drawable/ic_voice_full"
  10.             android:gravity="bottom" />
  11.     </item>
  12. </layer-list>
  1. //录音中....db为声音分贝，time为录音时长
  2.             @Override
  3.             public void onUpdate(double db, long time) {
  4.                 //根据分贝值来设置录音时话筒图标的上下波动
  5.                 mImageView.getDrawable().setLevel((int) (3000 + 6000 * db / 100));
  6.                 mTextView.setText(Defined.getDate(time));
  7.                 time_Long=(int)(time/1000);
  8.             }
