You need to set a class level variable and determine what click has transpired. The difficulty in this approach is defining when to reset the value.

private int _clicks = 0;

k = (Button)findViewById(R.id.button1);
k.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View v) {
        int count = ++_clicks;

        if(count == 1)
             //do whatever
        if(count == 2)
             //do whatever
        if(count == 3)
             //do whatever
    }
});

A better approach would to simply assign multiple handlers to multiple buttons and perform the action needed for the button. This would allow you to define a 1:1 relationship and will make your code much more manageable down the road.

EDIT: To record sound there are plenty of examples on the web.

  public class AudioRecorder {

  final MediaRecorder recorder = new MediaRecorder();
  final String path;

  /**
   * Creates a new audio recording at the given path (relative to root of SD card).
   */
  public AudioRecorder(String path) {
    this.path = sanitizePath(path);
  }

  private String sanitizePath(String path) {
    if (!path.startsWith("/")) {
      path = "/" + path;
    }
    if (!path.contains(".")) {
      path += ".3gp";
    }
    return Environment.getExternalStorageDirectory().getAbsolutePath() + path;
  }

  /**
   * Starts a new recording.
   */
  public void start() throws IOException {
    String state = android.os.Environment.getExternalStorageState();
    if(!state.equals(android.os.Environment.MEDIA_MOUNTED))  {
        throw new IOException("SD Card is not mounted.  It is " + state + ".");
    }

    // make sure the directory we plan to store the recording in exists
    File directory = new File(path).getParentFile();
    if (!directory.exists() && !directory.mkdirs()) {
      throw new IOException("Path to file could not be created.");
    }

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

  /**
   * Stops a recording that has been previously started.
   */
  public void stop() throws IOException {
    recorder.stop();
    recorder.release();
  }

}
