推荐答案

对不起，迟到的答案，但这里是一个工作code.It将棒棒堂工作，上述

Sorry for late answer but here is a working code.It will work on Lollipop and above

  private VirtualDisplay mVirtualDisplay;
  private MediaRecorder mMediaRecorder;
  private MediaProjection mMediaProjection;
  private MediaProjectionCallback callback;
     @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    MediaProjectionManager projectionManager = (MediaProjectionManager) 
    context.getSystemService(Context.MEDIA_PROJECTION_SERVICE);
        mMediaProjection.registerCallback(callback, null);
        initRecorder();
        mMediaRecorder.prepare();
        mVirtualDisplay = createVirtualDisplay();
        mMediaRecorder.start();
}

public void initRecorder() {
        path = "/sdcard/Record/video + ".mp4";
        recId = "capture-" + System.currentTimeMillis() + ".mp4";
        File myDirectory = new File(Environment.getExternalStorageDirectory(), "Record");

            mMediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
            mMediaRecorder.setVideoSource(MediaRecorder.VideoSource.SURFACE);
            mMediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
            mMediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.H264);
            mMediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
            mMediaRecorder.setVideoEncodingBitRate(MainFragment.bitRate);          
            mMediaRecorder.setVideoFrameRate(30);
            mMediaRecorder.setVideoSize(MainFragment.DISPLAY_WIDTH,
            MainFragment.DISPLAY_HEIGHT);
            mMediaRecorder.setOutputFile(path);
    }


    private VirtualDisplay createVirtualDisplay() {
        return mMediaProjection.createVirtualDisplay("MainActivity",
                MainFragment.DISPLAY_WIDTH, MainFragment.DISPLAY_HEIGHT, MainFragment.screenDensity,
                DisplayManager.VIRTUAL_DISPLAY_FLAG_AUTO_MIRROR,
                mMediaRecorder.getSurface(), null /*Callbacks*/, null /*Handler*/);
    }

public class MediaProjectionCallback extends MediaProjection.Callback {
        @Override
        public void onStop() {
            mMediaRecorder.stop();
            // mMediaRecorder.reset();
            mMediaRecorder.release();
            mMediaProjection.unregisterCallback(callback);
            mMediaProjection = null;
            mMediaRecorder = null;
        }
