RelativeLayout alignment rules do not work in DialogFragment

Question

I have a dialogue with RelativeLayout. It works correctly in normal activities, but when I decided to move it to DialogFragment, most of the alignment rules stopped working. Here is the layout:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:minHeight="250dp" >

    <TextView
        android:id="@+id/label_copyright"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:layout_marginTop="20dp"
        android:text="Copyright (c) 2013 Copyright"
        android:textSize="8dp" />

    <TextView
        android:id="@+id/label_version"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_above="@+id/label_copyright"
        android:layout_marginTop="2dp"
        android:text="@null" />

    <TextView
        android:id="@+id/label_app_name"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_above="@+id/label_version"
        android:layout_centerHorizontal="true"
        android:layout_marginBottom="2dp"
        android:text="Application Name"
        android:textSize="25dp" />


    <ImageView
        android:id="@+id/image_app_logo"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_above="@+id/label_app_name"
        android:layout_centerHorizontal="true"
        android:layout_marginBottom="16dp"
        android:src="@drawable/field_public_required" />


    <TextView
        android:id="@+id/label_description"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_below="@+id/label_copyright"
        android:layout_marginTop="30dp"
        android:gravity="center"
        android:autoLink="web"
        android:text="application description with more details" />


</RelativeLayout>

Here's how it should work, and it really works like that when in action (screenshot of the Eclipse graphic layout):

And here is what it looks like when running the application with fragments:

Apparently, only the first view is centered, as expected, and all the rest are simply pushed to the top. No matter what minHeightI indicate in the layout, the behavior is always the same.

The code for creating the dialog box is very simple:

@Override
public Dialog onCreateDialog(Bundle savedInstanceState)
{
    LayoutInflater inflater = getActivity().getLayoutInflater();
    View view = inflater.inflate(R.layout.about, null);

    try
    {
      TextView t = (TextView)view.findViewById(R.id.label_version);
      t.setText(getActivity().getPackageManager().getPackageInfo(getActivity().getPackageName(), 0).versionName);
    }
    catch(NameNotFoundException e)
    {
    }

    return new AlertDialog.Builder(getActivity())
    .setView(view)
    .setTitle(R.string.about)
    .setPositiveButton(R.string.ok,
    new DialogInterface.OnClickListener()
    {
      public void onClick(DialogInterface dialog, int whichButton)
      {
      }
    }
    )
    .create();
}

What is wrong with this and how to fix it?

. - hacky, :

<LinearLayout android:layout_width="fill_parent"
              android:layout_height="fill_parent">
  <RelativeLayout android:layout_width="fill_parent"
                  android:layout_height="fill_parent">
    <EditText android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:layout_centerVertical="true"
              android:layout_centerHorizontal="true"
              android:id="@+id/layout_form_field">
    <Button android:layout_below="@id/layout_form_field"/>

XML- :

 <?xml version="1.0" encoding="utf-8" ?>
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:orientation="vertical"
     android:layout_height="match_parent"
     android:layout_width="match_parent"
     android:gravity="center">
     <ImageView
          android:id="@+id/imageViewApplicationImage"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"/>
     <TextView
          android:id="@+id/textViewApplicationName"
          android:layout_width="match_parent"
          android:layout_height="wrap_content"/>
     <TextView
          android:id="@+id/textViewApplicationDescription"
          android:layout_width="match_parent"
          android:layout_height="wrap_content"/>
     <TextView
          android:id="@+id/textViewApplicationCopyright"
          android:layout_width="match_parent"
          android:layout_height="wrap_content"/>

</LinearLayout>
