Android - Dialog Fragment width keeps on matching parent

Question

Good day, apologies if this seems to be a duplicate of a question that's been asked before.

I have and Android App and I am displaying a Dialog Fragment. The problem I have is that the width of the Dialog Fragment is ignored when the base activity is showing it. Here's the code in my onCreateDialog function:

@Override  
public Dialog onCreateDialog(Bundle savedInstanceState) {  

    final Dialog dialog = new Dialog(getActivity());  
    dialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);
    dialog.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,  
            WindowManager.LayoutParams.FLAG_FULLSCREEN);  

    LayoutInflater layoutInflater = (LayoutInflater) getActivity()
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    View layout2 = layoutInflater.inflate(R.layout.fragment_item_dialog, null);

    dialog.setContentView(layout2);  
    setStyle(DialogFragment.STYLE_NORMAL, R.style.MyDialog);

    Window window = dialog.getWindow();
    window.setFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL,
            WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL);
    window.clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);

    window.setGravity(Gravity.TOP|Gravity.LEFT);

    WindowManager.LayoutParams params = window.getAttributes();
    params.x = 20;
    params.y = 470;
    params.width = WindowManager.LayoutParams.WRAP_CONTENT;
    params.height = WindowManager.LayoutParams.WRAP_CONTENT;

    params.copyFrom(window.getAttributes());

    window.setAttributes(params);
    // -- more code here
}

and here is my xml file fragment_item_dialog

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="400dp"
    android:layout_height="wrap_content" >  

    <!--- code here ---!>

</RelativeLayout>

The height is followed properly, but Android keeps on setting the width to match parent even though I told it to wrap content. The components inside my dialog Fragment does not exceed 400dp and I have no clue why Android is forcing my layout to match parent.

Does anyone know how to work around this? Any help is very much appreciated. Thanks.

Made it work, use the same code on onStart()

@Override
public void onResume() {
    // TODO Auto-generated method stub
    super.onResume();

    if (getDialog() == null)
        return;

    int width = 1100;
    int height = getResources().getDisplayMetrics().heightPixels;       
    getDialog().getWindow().setLayout(width, 
            WindowManager.LayoutParams.WRAP_CONTENT);

}
