React Native：react-native-popup-dialog不起作用

Question

当我长按要显示弹出对话框以输入备注的flatlist数据时，我正在使用flatlist来显示数据

这是onlongpress功能

saveGroup (){
      console.log("Long Press");
      this.setState({
        visibleGroup: "true",
      });
    }    

这是渲染行，当我长按数据以显示弹出对话框以输入备注

renderRow = (item) => {
        if(item.type=="D"){
            this.state.typetext="Dent"
        }
        if(item.type=="S"){
            this.state.typetext="Scratch"
        }
        if(item.type=="C"){
            this.state.typetext="Crack"
        }
        return (
            <ScrollView>
                 <View style={customStyles.listViewContainer} > 
                 <View style={{ flex: 1 }}>
                 <TouchableOpacity
                 underlayColor='#dddddd' onLongPress={() => this.saveGroup()}
                 >

                   {
