How to set the title of DialogFragment?

问题

This should be a simple task, but for some reason I can find a way to set the title of a DialogFragment. (I am setting the dialog contents using onCreateView overload).

The default style leaves a place for the title, but I can't find any method on the DialogFragment class to set it.

The title is somehow magically set when the onCreateDialog method is used to set the contents, so I wonder if this is by design, or there is a special trick to set it when using the onCreateView overload.

回答1:

You can use getDialog().setTitle("My Dialog Title")

Just like this:

public static class MyDialogFragment extends DialogFragment {
    ...
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        // Set title for this dialog
        getDialog().setTitle("My Dialog Title");

        View v = inflater.inflate(R.layout.mydialog, container, false);
        // ...
        return v;
    }
    // ...
}

Does overriding onCreateDialog and setting the title directly on the Dialog work? Like this:

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    Dialog dialog = super.onCreateDialog(savedInstanceState);
    dialog.setTitle("My Title");
    return dialog;
}

Jason's answer used to work for me, but now it needs the following additions to get the title to show.

Firstly, in your MyDialogFragment's onCreate() method, add:

setStyle(DialogFragment.STYLE_NORMAL, R.style.MyDialogFragmentStyle);

Then, in your styles.xml file, add:

<style name="MyDialogFragmentStyle" parent="Theme.AppCompat.Light.Dialog.Alert">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">false</item>
    <item name="android:windowActionBar">false</item>
    <item name="android:windowNoTitle">false</item>
</style>

After hours of trying different things, this is the only one that has done the trick for me.

NB - You may need to change the Theme.AppCompat.Light.Dialog.Alert to something else in order to match the style of your theme.

DialogFragment could be represented as dialog and as Activity. Use code below that would work properly for both

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    if (getShowsDialog()) {
        getDialog().setTitle(marketName);
    } else {
        getActivity().setTitle(marketName);
    }
}

You can take a look at the official docs. The way i did is like this:

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity())
            .setTitle("My Title");
    LayoutInflater inflater = getActivity().getLayoutInflater();
    View view = inflater.inflate(R.layout.my_layout, null);
    builder.setView(view);

    return builder.create();
}
