我工作的机器人。如何录制可通过麦克风音频文件，以及如何保存录音文件中的模拟器？

I am working in android. How can I record an audio file through microphone, and how can I save the recorded file in the emulator?

推荐答案

这是很容易录制音频的机器人。 什么，你需要做的是：

It is easy to record audio in android. What you need to do is :

1）创建介质记录类对象：MediaRecorder记录=新MediaRecorder（）; 2）在模拟器中，你无法保存记录的数据在内存中，所以你必须将其存储在SD卡。对于SD卡的可用性因此，首先检查：然后开始录制

1) Create the object for media record class : MediaRecorder recorder = new MediaRecorder(); 2) In the emulator, you're unable to store the recorded data in memory, so you have to store it on the sdcard. So first check for the SD Card availability:then start recording

String status = Environment.getExternalStorageState();
if(status.equals("mounted")){
   String path = your path;
}

recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile(path);
recorder.prepare();
recorder.start();

3） 要停止，活动覆盖停止方法

3) To stop, override stop method of activity

 recorder.stop();
 recorder.release();
