DialogFragment太宽，无法居中

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.dialog_fragment_layout, container, false);
    
    // 设置对话框样式
    getDialog().getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
    getDialog().getWindow().setLayout(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
    
    return view;
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setStyle(DialogFragment.STYLE_NORMAL, R.style.CustomDialogStyle);
}

<!-- res/values/styles.xml -->
<style name="CustomDialogStyle" parent="Theme.AppCompat.Dialog">
    <item name="android:windowIsFloating">true</item>
    <item name="android:windowBackground">@android:color/transparent</item>
    <item name="android:windowMinWidthMajor">@dimen/dialog_width</item>
    <item name="android:windowMinWidthMinor">@dimen/dialog_width</item>
</style>

@Override
public void onStart() {
    super.onStart();
    
    // 设置对话框的位置
    Dialog dialog = getDialog();
    if (dialog != null) {
        Window window = dialog.getWindow();
        WindowManager.LayoutParams params = window.getAttributes();
        params.gravity = Gravity.CENTER;
        window.setAttributes(params);
    }
}
