DialogFragment width shrink after specifying FEATURE_NO_TITLE

Question

So here is my onCreateView method:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
  getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE);
  View view = inflater.inflate(R.layout.my_view, container, false);
  ...
  return view;
}

And the layout itself is a LinearLayout with

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

For some reason, after adding the line getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE); the dialog shrunk to wrap the contents; in fact, one of the TextViews is forced to wrap its one line into two lines. I want the Dialog to fill the width of the screen, save some margin that I specify.

Answer 1

Use this line in and it will be full width, regardless of the children:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setStyle(DialogFragment.STYLE_NO_TITLE,
            android.R.style.Theme_Holo_Light_Dialog_NoActionBar_MinWidth);
}

The key is NoActionBar_MinWidth in the theme declaration.

Answer 2

I solve the problem, but I don't like the cause of the problem or the solution.

The problem was this, one of the children views was

<LinearLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"

changing it to

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"

did the trick.
