Question

How can I dynamically load an image into a dialog box in android

public Dialog onCreateDialog(Bundle savedInstanceState) {
        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());       
        LayoutInflater inflater = getActivity().getLayoutInflater();
        builder.setView(inflater.inflate(R.layout.popup, null));
}

I can only link static buttons and images into the view.

If I try to link images dynamically like

ImageView image = (ImageView) getActivity().findViewById(R.id.image);
image.setImageResource(R.drawable.icon);

image is being returned as a null object

Here is the solution

public Dialog onCreateDialog(Bundle savedInstanceState) {
        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());       
        LayoutInflater inflater = getActivity().getLayoutInflater();
        ViewGroup vg = (ViewGroup)inflater.inflate(R.layout.popup, null);
        ImageView image = (ImageView) vg.findViewById(R.id.image);
        image.setImageResource(R.drawable.icon);
        builder.setView(vg);
}

hope this helps!
