如何在Camera2 API中将已处理的帧绘制回屏幕

Question

I'm attempting to grab frames of video from the Camera2 API in Android Studio and do some simple image processing on each frame.

The issue I am having is in drawing the processed frame back to the screen.

I am using code from the camera2raw example.

I'm modifying the pixel value in the buffer which stores all the frames.

Right now I'm just adding a constant value to each pixel to see if the image on the screen is modified or not.

The image on the screen is not changed by adding even a very large value to each pixel.

Therefore, I'm fairly confident I'm not writing the modified pixel values back to the screen.

Here is a code snippets from relevant portions of the program:

ImageReader.OnImageAvailableListener imageAvailableListener = new ImageReader.OnImageAvailableListener() {
    @Override
    public void onImageAvailable(ImageReader reader) {
        Image image = null;
        try {
            image = reader.acquireLatestImage();

            ByteBuffer Y = image.getPlanes()[0].getBuffer();
            ByteBuffer U = image.getPlanes()[1].getBuffer();
            ByteBuffer V = image.getPlanes()[2].getBuffer();

            int Yb = Y.remaining();
            int Ub = U.remaining();
            int Vb = V.remaining();

            byte[] data = new byte[Yb + Ub + Vb ];
            //your data length should be this byte array length.

            for (int i = 0; i < 512; i++)
            {
                for (int j = 0; j < 512; j++)
                {
                    int idx = i * 512 + j;
                    data[idx] += 255;
                }
            }
            // Screen should now show some distortion.
            Y.get(data, 0, Yb);
            U.get(data, Yb, Ub);
            V.get(data, Yb+ Ub, Vb);

        } catch (Exception ee) {
        } finally {
            if (image != null)
                image.close();
        }
    }

    //void save(byte[] bytes) {
        File file12 = getOutputMediaFile();
        OutputStream outputStream = null;
        try {
            outputStream = new FileOutputStream(file12);
            outputStream.write(bytes);
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            try {
                if (outputStream != null)
                    outputStream.close();
            } catch (Exception e) {
            }
        }
   // }
};

Please let me know if providing further explanation or sections of code will help make my question more clear.

Can someone please tell me how I write back to the screen the modified frame?

I have also tried doing this:

// Convert bytes data into a Bitmap
Bitmap bmp = BitmapFactory.decodeByteArray(data, 0, data.length);
ImageView imageView = new ImageView(MainActivity.this);
// Set the Bitmap data to the ImageView
imageView.setImageBitmap(bmp);
// Get the Root View of the layout
ViewGroup layout = (ViewGroup) findViewById(android.R.id.content);
// Add the ImageView to the Layout
layout.addView(imageView);

There are posts related to this issue but none has an exact solution. Can anyone provide me with a link to detailed step by step instructions of how to achieve what I described?
