Android: How to create a Dialog without a title?

Previous version of this answer, which is overcomplicated:

You need to use an AlertDialog. There's a good explanation on the Android Developer's site about custom dialogs.

In very short summary, you do this with code like copied below from the official website. That takes a custom layot file, inflates it, gives it some basic text and icon, then creates it. You'd show it then with alertDialog.show().

AlertDialog.Builder builder;
AlertDialog alertDialog;

Context mContext = getApplicationContext();
LayoutInflater inflater = (LayoutInflater)
        mContext.getSystemService(LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.custom_dialog,
        (ViewGroup) findViewById(R.id.layout_root));

TextView text = (TextView) layout.findViewById(R.id.text);
text.setText("Hello, this is a custom dialog!");
ImageView image = (ImageView) layout.findViewById(R.id.image);
image.setImageResource(R.drawable.android);

builder = new AlertDialog.Builder(mContext);
builder.setView(layout);
alertDialog = builder.create();

In response to comment:

I assume that TextView with the id nr is in the View you are inflating with View view = inflater..... If so, then you need to change just one bit: instead of dialog.findView... make it view.findView.... Then once you've done that, remember to use dialog.show(), or even builder.show() without bothering to do builder.create().

Removing title of a DialogFragment

Create your dialog normally, and add a line like this before showing:

myDialog.getDialog().requestWindowFeature(Window.FEATURE_NO_TITLE);

Edit:
added the .getDialog() call

Edit 2: Tested with the link of your example

I have tested this code now and it works:

public class HelpDialog extends DialogFragment {

    public HelpDialog() {
        // Empty constructor required for DialogFragment
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        //Inflate the XML view for the help dialog fragment
        View view = inflater.inflate(R.my_layout, container);

        HelpDialog.this.getDialog().requestWindowFeature(Window.FEATURE_NO_TITLE);

        return view;
    }

}

and i called the Dialog like that :

HelpDialog dialog = new HelpDialog();
dialog.show(getFragmentManager(),"test");

how to remove title from DialogFragment?

you must override onCreateDialog method in your dialogfragment class.

@Override
   public Dialog onCreateDialog(final Bundle savedInstanceState) {
      RelativeLayout root = new RelativeLayout(getActivity());
      root.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
      final Dialog dialog = new Dialog(getActivity());
      dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
      dialog.setContentView(root);
      dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.WHITE));
      dialog.getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);

      return dialog;
   }
