Dynamic DialogFragment - Android

This is frustrating... I've been playing with this stupid DialogFragment for half a day, trying all sort of pieces of code, Questions from StackOverFlow, just to realize, that they are all useless!!

It is as simple as the fact that when using the DialogFragment the LayoutParams of the parent view are not been set, thus renders the dialog badly.

After some thinking about it I've came up with this:

In res/values/stylex.xml:

<resources>
    ...
    <style name="AlertDialogStyle" >
        <item name="android:cacheColorHint">@android:color/transparent</item>
        <item name="android:windowBackground">@android:color/transparent</item>
    </style>
   ...
</resources>

In res/layout/alert_dialog_body.xml:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/tools"
    android:id="@+id/xx"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:background="@android:drawable/alert_dark_frame"
        android:orientation="vertical" >

        <TextView
            android:id="@+id/Title"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginLeft="15dp"
            android:layout_marginTop="10dp"
            android:text="Large Text"
            android:textAppearance="?android:attr/textAppearanceLarge" />

        <ImageView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginLeft="2dp"
            android:layout_marginRight="2dp"
            android:layout_marginTop="5dp"
            android:contentDescription="Separator"
            android:scaleType="fitXY"
            android:src="@drawable/settings_separator"
            app:ignore="HardcodedText" />

        <TextView
            android:id="@+id/AlertBody"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="center_horizontal"
            android:layout_marginBottom="5dp"
            android:layout_marginLeft="10dp"
            android:layout_marginRight="10dp"
            android:layout_marginTop="5dp"
            android:text="TextView"
            android:textAppearance="?android:attr/textAppearanceMedium" />

        <Button
            android:id="@+id/DialogButton"
            style="?android:attr/buttonStyleSmall"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center_horizontal"
            android:layout_marginBottom="10dp"
            android:layout_marginLeft="20dp"
            android:layout_marginRight="20dp"
            android:layout_marginTop="15dp"
            android:text="Button" />
    </LinearLayout>

</RelativeLayout>

(The RelativeLayout is the trick...)

and the Dialog fragment:

public class MyDialogFragment
  extends DialogFragment {
 
 protected final String TAG = getClass().getSimpleName();
 
 private int titleId;
 
 private int bodyId;
 
 private int buttonId;
 
 public MyDialogFragment(int titleId, int bodyId, int buttonId) {
  super();
  this.titleId = titleId;
  this.bodyId = bodyId;
  this.buttonId = buttonId;
 }
 
 @Override
 public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
  
  View view = inflater.inflate(R.layout.alert_dialog_body, container);
  TextView title = (TextView) view.findViewById(R.id.Title);
  TextView body = (TextView) view.findViewById(R.id.AlertBody);
  Button button = (Button) view.findViewById(R.id.DialogButton);
  
  button.setOnClickListener(new OnClickListener() {
   
   @Override
   public void onClick(View v) {
    getDialog().dismiss();
   }
  });

  button.setText(buttonId);
  title.setText(titleId);
  body.setText(bodyId);
  return view;
 }
 
 @Override
 public void onAttach(android.app.Activity activity) {
  super.onAttach(activity);
 }
 
 @Override
 public void onCreate(android.os.Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setStyle(DialogFragment.STYLE_NO_FRAME, R.style.AlertDialogStyle);
 }
 
}

And Just in case you would actually want to use this:

MyDialogFragment dialogFragment = new MyDialogFragment(R.string.title,R.string.body,R.string.button_label);
dialogFragment .setCancelable(false);
dialogFragment .show(getSupportFragmentManager(), "Dialog Fragment");
