@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    Dialog dialog = super.onCreateDialog(savedInstanceState);
    dialog.setOnShowListener(dialogInterface -> {
        // 隐藏键盘
        InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(dialog.getWindow().getDecorView().getWindowToken(), 0);
    });
    return dialog;
}
