How to set the title of DialogFragment?

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;
    }
    // ...
}
