Android 在片段上第二次膨胀对话框时出错

我使用了这个库：为了在我的应用程序上有一个颜色选择器，在实现它之后，我不能多次使用它，当我第二次尝试打开颜色选择器时，它会出现以下错误：

我在这里发布之前搜索过，但无法以任何方式修复此错误。

是否可能（每次单击时）多次调用

show（）

，而颜色选择器不支持此功能

如果这是问题所在，您可以声明为每次单击创建一个新的颜色选择器。例如：

@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    View RootView = inflater.inflate(R.layout.fragment_addcategory, container, false);

    db = new SQLiteHandler(getApplicationContext());
    categoriesspinner = (Spinner) RootView.findViewById(R.id.spinnercategory);

    Button color = (Button) RootView.findViewById(R.id.color);
    color.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            colorPicker = new ColorPicker(getActivity());
            colorPicker.show();
        }
    });

    return RootView;
}

@Override
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);

    getActivity().setTitle("Adicionar categoria");

    if (colorPicker != null) {
        colorPicker.setOnChooseColorListener(new ColorPicker.OnChooseColorListener() {
            @Override
            public void onChooseColor(int position, int color) {
                Log.d("color:", String.valueOf(color));
                Log.d("color:", String.valueOf(position));
            }

            @Override
            public void onCancel() {
            }
        });
    }

    loadCategoriesSpinner();
}
