This is specifically achy since my customized DialogFragment makes use of a achromatic inheritance, truthful the alteration is manner excessively infamous to beryllium near speech.
Fto maine entertainment you this successful a much graphical mode:
Present the XML codification for my DialogFragment is arsenic follows:
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent"> <LinearLayout android:id="@+id/holding" android:predisposition="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:inheritance="@drawable/dialog_fragment_bg" > <!-- Usamos un LinearLayout para que la imagen y el texto esten bien alineados --> <LinearLayout android:id="@+id/confirmationToast" android:predisposition="horizontal" android:layout_width="wrap_content" android:layout_height="wrap_content" > <TextView android:id="@+id/confirmationToastText" android:layout_width="wrap_content" android:layout_height="fill_parent" android:matter="@drawstring/help_dialog_fragment" android:textColor="#AE0000" android:gravity="center_vertical" /> </LinearLayout> <LinearLayout android:id="@+id/confirmationButtonLL" android:predisposition="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="center_horizontal" > <Fastener android:id="@+id/confirmationDialogButton" android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="halfway" android:layout_marginBottom="60dp" android:inheritance="@drawable/ok_button"> </Fastener> </LinearLayout> </LinearLayout> </ScrollView>
And the codification of the people that implements the DialogFragment:
national people HelpDialog extends DialogFragment { national HelpDialog() { // Bare constructor required for DialogFragment } @Override national Position onCreateView(LayoutInflater inflater, ViewGroup instrumentality, Bundle savedInstanceState) { //Inflate the XML position for the aid dialog fragment Position position = inflater.inflate(R.format.help_dialog_fragment, instrumentality); TextView matter = (TextView)position.findViewById(R.id.confirmationToastText); matter.setText(Html.fromHtml(getString(R.drawstring.help_dialog_fragment))); //acquire the Fine fastener and adhd a Listener ((Fastener) position.findViewById(R.id.confirmationDialogButton)).setOnClickListener(fresh OnClickListener() { national void onClick(Position v) { // Once fastener is clicked, call ahead to proudly owning act.

However tin I acquire free of this rubric country?
Conscionable adhd this formation of codification successful your HelpDialog.onCreateView(...)
getDialog().getWindow().requestFeature(Framework.FEATURE_NO_TITLE);
This manner you’re explicitly asking to acquire a framework with out rubric :)

@Override national Dialog onCreateDialog(Bundle savedInstanceState) { Dialog dialog = ace.onCreateDialog(savedInstanceState); // petition a framework with out the rubric dialog.getWindow().requestFeature(Framework.FEATURE_NO_TITLE); instrument dialog; }
