我正在使用stack navigator中的tab navigator。当在tab navigator中移动到下一个选项卡时,会有一点暂停,然后移动到下一个选项卡…索引文件的代码是

import HomeButton from './HomeButton'
import ProfileScreen from './ProfileScreen'
import Granjur from './granjur'
const background=require("./flag/1.jpg");

export default class TabViewExample extends Component {
render(){
const { navigation } = this.props;
return(

    <App navigation={ navigation }/>

);
}
}
const MyApp = TabNavigator({
  Home: {
    screen: HomeButton,

    screen: ProfileScreen,
  },

},

 {
   swipeEnabled:false,
   initialRouteName: 'Home',

  tabBarOptions: {
    activeTintColor: '#e91e63',
  },
});

const Simple = StackNavigator({
  Login: {
    screen: Login,
  },
  signup: {
    screen: SignUp,
  },
  forget:{
    screen:forget
  },
  dashbord:{

  }
});
AppRegistry.registerComponent('TabNavigator', () => Simple);

}
const MyApp=TabNavigator({

},
{
swipeabled:false,
initialRouteName:“主页”,
选项卡选项:{

注册表组件('TabNavigator',()=>Simple);
我在那个选项卡视图中也使用了可滚动的选项卡视图,也出现了问题。在第二个选项卡中,我有一个可滑动的列表视图,可能是由于这个错误,我是如何解决这个问题的?配置文件屏幕的代码是什么
