问题
I need to place a custom title to my DialogFragment
.
getDialog().setTitle("My Title");
is not enough for me because I want to change the title text and background colors.
As you can see from the image below, with getDialog().setTitle("My Title");
I've no customization (as far as I know), ie, the text color is black and the background is white.
My objective is to have My Title
customized as seen by Custom Title
. I've been looking around the API and I couldn't find any method to load a view into the title section.
Anyone knows how can I customize or set/inject a view into the FragmentDialog
?

You have to create a custom dialog by overiding onCreateDialog like so:
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
LayoutInflater inflater = getActivity().getLayoutInflater();
dialogView = inflater.inflate(R.layout.dialog_change_password, null);
/* Anything that needs to be done to the view, ie.
on click listeners, postivie/negative buttons,
values being changed etc */
builder.setView(dialogView);
return builder.create();
}
and the dialog_change_password.xml:
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="@color/white_grey">
<TextView
android:text="@string/change_password"
android:id="@+id/title"
style="@style/dialogHeading" />
<LinearLayout
android:layout_marginTop="10dp"
style="@style/dialogSection">
<LinearLayout
style="@style/PasswordChangeRow">
<TextView
style="@style/PasswordChangeLabel"
android:text="@string/new_password"/>
<EditText
style="@style/PasswordChangeField"
android:id="@+id/password"
android:inputType="textPassword"/>
</LinearLayout>
<LinearLayout
style="@style/PasswordChangeRow">
<TextView
style="@style/PasswordChangeLabel"
android:text="@string/confirm_password"/>
<EditText
style="@style/PasswordChangeField"
android:id="@+id/confirmPassword"
android:inputType="textPassword"/>
</LinearLayout>
</LinearLayout>
<TextView
android:text="@string/password_conditions_message"
style="@style/dialogMessage" />
</LinearLayout>
Obviously that xml is a bit more complex that what is needed but is just an example of what can be done, it looks like this

You can use setCustomTitle
method, where you can inflate your own fully customized layout
Example
import android.support.v4.app.DialogFragment;
public class PromoDetailDialogFragment extends DialogFragment {
public Dialog onCreateDialog(Bundle savedInstanceState) {
View titleView = getActivity().getLayoutInflater().inflate(R.layout.my_title, null);
TextView tv = (TextView) titleView.findViewById(R.id.my_title_textView);
tv.setText("title");
AlertDialog dialog = new AlertDialog.Builder(getContext())
.setCustomTitle(titleView)
.setMessage("message")
.setCancelable(true)
.create();
return dialog;
}
}
This way is cleaner and much more powerful
