React native 在react navigation选项卡Navigator中，如何设置参数

当我点击电影列表时，我想传递一个参数。如何使用setParams？

在呈现应用选项卡时，可以通过以下方式传递参数：

const AppTabs = TabNavigator({
Home: {
  screen: FilmList,
},
FilmCinemaList: {
  screen: FilmCinemaList,
  path: 'cart',
},
FilmGoodsList: {
    screen: FilmGoodsList,
},
FilmMe: {
    screen: FilmMe,
},
})

.

通过navigationOptions，您要做的是在将屏幕传递到选项卡Navigator之前设置屏幕的navigationOptions，如下所示：

this.props.screenProps.FilmCinemaList

然后你就可以访问它了

FilmCinemaList.navigationOptions = {
 'param1':'value1';
};
const AppTabs = TabNavigator({
Home: {
  screen: FilmList,
},
FilmCinemaList: {
  screen: FilmCinemaList,
  path: 'cart',
},
FilmGoodsList: {
    screen: FilmGoodsList,
},
FilmMe: {
    screen: FilmMe,
},
})

当你需要的时候。

对我有用！，谢谢

FilmCinemaList.navigationOptions = {
 'param1':'value1';
};
const AppTabs = TabNavigator({
Home: {
  screen: FilmList,
},
FilmCinemaList: {
  screen: FilmCinemaList,
  path: 'cart',
},
FilmGoodsList: {
    screen: FilmGoodsList,
},
FilmMe: {
    screen: FilmMe,
},
})

FilmCinemaList.navigationOptions.param1
