Answer 1

ImageView will not redraw if "new" URI is the same like old one. "View.invalidate()" will not work. To "force" update you can do:

public void onResume() {
  super.onResume();
  ImageView myImageView = (ImageView)findViewById(R.id.contact_image);
  if (hasImage) {
    myImageView.setImageDrawable(null); // <--- added to force redraw of ImageView
    myImageView.setImageURI(Uri.fromFile(getFileStreamPath(TEMP_PHOTO_FILE)));
  }
}

I had a similar problem where I was using the devices camera to take a picture and then wanting the imageView in the original screen to refresh when I returned to it. The solution was to call View.invalidate() in onResume().

I would suggest this thing solution. After trying lot of solutions i found this one worked for me.

final Handler handler = new Handler();
                    handler.postDelayed(new Runnable() {
                        @Override
                        public void run() {
                            //Do something after 1000ms
                            ivProfilePic.setImageBitmap(bitImage);

                        }
                    }, 1000);

Answer 4

invalidate() not worked. Try hack :

    imageView.setImageURI(null);
    imageView.setImageURI(newUri);

Answer 5

To force redrawing your widget/View just call View.invalidate();

        })

Use this func in your view controller
