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
//Add it in your root build.gradle at the end of repositories:
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}
Step 2. Add the dependency
//Add the dependency
dependencies {
implementation 'com.github.tyhjh:AudioRecording:v1.0.0'
}
基本使用
//设置录音保存位置
AudioRecordUtil.init(Environment.getExternalStorageDirectory() + "/audio/");
recordUtil = AudioRecordUtil.getInstance();
//开始录音
recordUtil.startRecord(MainActivity.this);
//取消录音，时间太短须取消
recordUtil.cancelRecord(MainActivity.this);
//结束录音（保存录音文件）
recordUtil.stopRecord(MainActivity.this);
//录音监听
AudioRecordUtil.getInstance().setOnAudioStatusUpdateListener(new AudioRecordUtil.OnAudioStatusUpdateListener() {
@Override
public void onUpdate(double db, long time) {
//根据分贝值来设置录音时话筒图标的上下波动
}
@Override
public void onStop(final String filePath) {
//获取录音文件
}
});
具体实现
录音时候关闭或开启其他声音
public static boolean muteAudioFocus(Context context, boolean bMute) {
if (context == null) {
Log.d("ANDROID_LAB", "context is null.");
return false;
}
boolean bool = false;
AudioManager am = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
//关闭声音
if (bMute) {
int result = am.requestAudioFocus(null, AudioManager.STREAM_MUSIC, AudioManager.AUDIOFOCUS_GAIN_TRANSIENT);
bool = result == AudioManager.AUDIOFOCUS_REQUEST_GRANTED;
} else {
//恢复声音
int result = am.abandonAudioFocus(null);
bool = result == AudioManager.AUDIOFOCUS_REQUEST_GRANTED;
}
Log.d("ANDROID_LAB", "pauseMusic bMute=" + bMute + " result=" + bool);
return bool;
}
一个录音的类

}
调用录音的类并实现其中的方法
//录音回调
mAudioRecoderUtils.setOnAudioStatusUpdateListener(new AudioRecoderUtils.OnAudioStatusUpdateListener() {
//录音中....db为声音分贝，time为录音时长
@Override
public void onUpdate(double db, long time) {
//根据分贝值来设置录音时话筒图标的上下波动，下面有讲解
mImageView.getDrawable().setLevel((int) (3000 + 6000 * db / 100));
mTextView.setText(Defined.getDate(time));
time_Long=(int)(time/1000);
}
//录音结束，filePath为保存路径
@Override
public void onStop(String filePath) {
//发送语音
JSONObject json = null;
Defined.muteAudioFocus(SendMessage.this,false);
try {
json = new JSONObject(getJson.getMsg("null", 2, time_Long, getString(R.string.singleTalk), linkMan.getId()));
Messge messge = new Messge(json);
messge.setSoundPath(filePath);
updateView(messge);
sendVoice(filePath,messges.size()-1);
} catch (JSONException e) {
e.printStackTrace();
}
mTextView.setText("00:00");
}
});
//录音
Defined.muteAudioFocus(SendMessage.this,true);
switch (event.getAction()){
case MotionEvent.ACTION_DOWN:
y=event.getRawY();
time = System.currentTimeMillis();
mPop.showAtLocation(ll_bg, Gravity.CENTER,0,0);
try {
mAudioRecoderUtils.startRecord();
}catch (RuntimeException e){
e.printStackTrace();
Snackbar.make(iv_sound,"先允许调用系统录音权限",Snackbar.LENGTH_SHORT).show();
}
iv_sound.startAnimation(expend);
break;
case MotionEvent.ACTION_UP:
if(System.currentTimeMillis()-time<1000){
Snackbar.make(iv_sound,"录音时间过短，请重试",Snackbar.LENGTH_SHORT).show();
mAudioRecoderUtils.cancelRecord();
mPop.dismiss();
iv_sound.startAnimation(noexpend);
break;
}else if(y-event.getRawY()>300){
Snackbar.make(iv_sound,"已取消发送语音",Snackbar.LENGTH_SHORT).show();
mAudioRecoderUtils.cancelRecord();
mPop.dismiss();
iv_sound.startAnimation(noexpend);
break;
}else {
try{
mAudioRecoderUtils.stopRecord(); //结束录音（保存录音文件）
}catch (Exception e){
e.printStackTrace();
Snackbar.make(iv_sound,"先允许调用系统录音权限",Snackbar.LENGTH_SHORT).show();
}
mPop.dismiss();
iv_sound.startAnimation(noexpend);
break;
}
case MotionEvent.ACTION_CANCEL:
mAudioRecoderUtils.cancelRecord(); //取消录音（不保存录音文件）
mPop.dismiss();
iv_sound.startAnimation(noexpend);
break;
}
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
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。
-
//录音中....db为声音分贝，time为录音时长
@Override
public void onUpdate(double db, long time) {
//根据分贝值来设置录音时话筒图标的上下波动
mImageView.getDrawable().setLevel((int) (3000 + 6000 * db / 100));
mTextView.setText(Defined.getDate(time));
time_Long=(int)(time/1000);
}
