            if (null!=mOnCompleteClickListen){
                mOnCompleteClickListen.onComplete(cacheFilePath);
            }
        });
    }
 
 
    boolean isRecording = false;
    public void startRecord(){
        if(mr==null){
            mr = new MediaRecorder();
            File  savePath= null;
            try {

            } catch (Exception e) {
                e.printStackTrace();
            }
            mr.setAudioSource(MediaRecorder.AudioSource.MIC);      // 设置录音的输入源

        }
    }
 
    private OnCompleteClickListen listener;
    public void setOnCompleteClickListen(OnCompleteClickListen onCompleteClickListen){
        listener=onCompleteClickListen;
    }
 
 
    /**
     * 设置确定取消按钮的回调
     */
    public interface OnCompleteClickListen {
        void onComplete(String path);
    }
 
    @Override
    public void onDetachedFromWindow() {
        super.onDetachedFromWindow();
        stopRecord();
    }
}

2.调用及销毁

    SoundRecordDialog mSrd;
    private void showSoundRecordDialog(){
        if (null!=mSrd && mSrd.isShowing()){
            return;
        }
         mSrd=new SoundRecordDialog(this, new SoundRecordDialog.OnCompleteClickListen() {
            @Override
            public void onComplete(String path) {
                mSrd.dismiss();
                if (null==path || TextUtils.isEmpty(path)){
                    return;
                }
//                Log.e("点击完成",path);
                file=new File(path);
                uploadFileToServer(AUDIO);
            }
        });
        mSrd.show();
    }
 
 
 
 
    @Override
    protected void onDestroy() {
        if (null!=mSrd){
            mSrd.dismiss();
            mSrd=null;
        }
    }

3.布局文件

"1.0" encoding="utf-8"?>
<androidx.appcompat.widget.LinearLayoutCompat
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="250dp"
    android:layout_height="250dp"
    android:gravity="center"
    android:background="@drawable/shape_rec_c15all"
    android:orientation="vertical">
 
 
    <ImageView
        android:id="@+id/iv_sound_record"
        android:layout_width="100dp"
        android:layout_height="100dp"
        android:background="@mipmap/icon_sound_record_green"/>
 
    <TextView
        android:id="@+id/tv_status"
        android:layout_marginTop="10dp"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="按住说话"/>
 
    <TextView
        android:id="@+id/tv_finish"
        android:layout_marginTop="30dp"
        android:layout_width="180dp"
        android:layout_height="45dp"
        android:background="@color/main_color"
        android:gravity="center"
        android:textColor="@color/white"
        android:text="完成"/>
 
androidx.appcompat.widget.LinearLayoutCompat>
