要实现Android屏幕共享并使用surface参数，可以按照以下步骤进行操作：

1. 在AndroidManifest.xml文件中添加必要的权限：

2. 创建一个MediaProjectionManager实例：

MediaProjectionManager mediaProjectionManager = (MediaProjectionManager) getSystemService(Context.MEDIA_PROJECTION_SERVICE);

3. 请求屏幕捕获权限：

Intent captureIntent = mediaProjectionManager.createScreenCaptureIntent();
startActivityForResult(captureIntent, REQUEST_CODE_CAPTURE);

4. 在onActivityResult方法中处理屏幕捕获权限的结果：

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == REQUEST_CODE_CAPTURE && resultCode == RESULT_OK) {
        MediaProjection mediaProjection = mediaProjectionManager.getMediaProjection(resultCode, data);
        if (mediaProjection != null) {
            // 开始屏幕共享
            startScreenSharing(mediaProjection);
        }
    }
}

5. 在startScreenSharing方法中开始屏幕共享：

private void startScreenSharing(MediaProjection mediaProjection) {
    DisplayMetrics metrics = getResources().getDisplayMetrics();
    int screenWidth = metrics.widthPixels;
    int screenHeight = metrics.heightPixels;

    MediaRecorder mediaRecorder = new MediaRecorder();
    mediaRecorder.setVideoSource(MediaRecorder.VideoSource.SURFACE);
    mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
    mediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.H264);
    mediaRecorder.setVideoEncodingBitRate(512 * 1000);
    mediaRecorder.setVideoFrameRate(30);
    mediaRecorder.setVideoSize(screenWidth, screenHeight);

    // 设置输出文件路径
    String outputPath = Environment.getExternalStorageDirectory().getPath() + "/screen_record.mp4";
    mediaRecorder.setOutputFile(outputPath);

    try {
        mediaRecorder.prepare();
    } catch (IOException e) {
        e.printStackTrace();
    }

    Surface surface = mediaRecorder.getSurface();
    VirtualDisplay virtualDisplay = mediaProjection.createVirtualDisplay("ScreenSharing",
            screenWidth, screenHeight, metrics.densityDpi,
            DisplayManager.VIRTUAL_DISPLAY_FLAG_AUTO_MIRROR,
            surface, null, null);

    mediaRecorder.start();

    // 停止屏幕共享
    // mediaRecorder.stop();
    // mediaRecorder.release();
    // virtualDisplay.release();
}

这是一个简单的示例，它会将屏幕共享的内容录制为一个MP4文件。你可以根据自己的需求调整参数和处理方式。
