How to display an `Image` in the `ImageView`?

Question

I have an ImageView object acquired from the .xml file:

mCameraView = (ImageView) findViewById(R.id.camera_view);

I record an image taken from the camera many times a second. For each new image frame the following method gets called.

@Override
public void onImageAvailable(ImageReader reader) {
    Image image = reader.acquireLatestImage();
    mCameraView.somehowDisplay(image); // HOW?
}

I want place the image into the image view: How to do that?

more details please....where is the 'image' located? In the apps context? In the gallery? — letsCode, Aug 28 '17 at 15:15

ByteBuffer buffer = image.getPlanes()[0].getBuffer();
byte[] bytes = new byte[buffer.remaining()];
buffer.get(bytes);
Bitmap myBitmap = BitmapFactory.decodeByteArray(bytes,0,bytes.length,null);
mCameraView.setImageBitmap(myBitmap);

This should work.

Hmm, this does successfully convert the Image object into the Bitmap object, but the image is not shown on the screen. – mercury0114 Aug 28 '17 at 15:55
I think you are going to need to override a method onActivityResult. Look into it. – letsCode Aug 28 '17 at 18:04
