Could not implement in imageview

[ajay1295]

I'm currently working on Document scanner app. My app will first open opencv camera, it will detect document in camera screen and captured image will display in next screen in imageview. I want to apply this scanLibrary on this imageview. But i cannot. Can somebody help me to that?

    ` public class CameraButton extends CameraScreen  {
     private FloatingActionButton btnCamera;
     private ImageView imgview;
     private static final int REQUEST_CODE = 99;
     @Override
     protected void onCreate(Bundle savedInstanceState) {
    super.onCreate( savedInstanceState );
    setContentView( R.layout.activity_camera_button );

    btnCamera = (FloatingActionButton) findViewById( R.id.btnCamera );
    imgview = (ImageView) findViewById( R.id.imgview );
    byte[] byteArray = getIntent().getByteArrayExtra( "image" );
    Bitmap bitmap = BitmapFactory.decodeByteArray( byteArray, 0, byteArray.length );
    Bitmap b = Bitmap.createScaledBitmap( bitmap, 600, 600, true );

    imgview.setImageBitmap( b );

    Intent intent = new Intent(this, ScanActivity.class);
    intent.putExtra( ScanConstants.SELECTED_BITMAP, byteArray );
    startActivityForResult(intent, REQUEST_CODE);

    btnCamera = (FloatingActionButton) findViewById( R.id.btnCamera );
    btnCamera.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            startActivity(new Intent(CameraButton.this, CameraScreen.class));
        }
    });
     }
       @Override
      protected void onActivityResult(int requestCode, int resultCode, Intent data) {
      super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == REQUEST_CODE && resultCode == Activity.RESULT_OK) {
        Uri uri = data.getExtras().getParcelable(ScanConstants.SCANNED_RESULT);
        Bitmap bitmap = null;
        try {
            bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), uri);
            getContentResolver().delete(uri, null, null);
            imgview.setImageBitmap(bitmap);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
