将 ContainsFunction的call函数改为以下内容 修复bug

public class ContainsFunction implements FilterFunction { public Object call(ViewImage element, List<SyntaxNode> params) { boolean isContains = false; if (params.get(0).calc(element) != null) { isContains = params.get(0).calc(element).toString().contains(params.get(1).calc(element).toString()); } return isContains; }

public String getName() {
    return "contains";
}

}
