React Native，如果从项目列表中选择了一个项目详细信息，该如何显示一个项目详细信息

Question

我是新来的人，对当地人有反应。我有一个组件，使用带有宁静API的axios显示来自sqlite数据库的进度，我也使用redux。

我想从预付款列表中选择一个预付款记录，以便转到该预付款详细信息页面。但是，目前我不知道如何实现它。

**advanceActions.js**

import axios from "axios";
import {
  GET_ADVANCES,
  DETAIL_ADVANCE,

} from "./types";

//FETCH ADVANCES

export const getAdvances = () => dispatch => {
  axios
    .get("http://localhost:8000/api/advance/")
    .then(res => {
      dispatch({
        type: GET_ADVANCES,
        payload: res.data
      });
    })
    .catch(err => console.log(err));
};

    // GET ONE ADVANCE
export const detailAdvance = id => dispatch => {
  axios
    .get(`http://localhost:8000/api/advance/${id}/`)
    .then(res => {
      dispatch({
        type: DETAIL_ADVANCE,
        payload: res.data
      });
    })
    .catch(err => console.log("Axios not able to fetch single advance", err));
};

advanceReducers.js

import {
  GET_ADVANCES,
  DETAIL_ADVANCE,
} from "../actions/types";

const initialState = {
  items: [],
  item: {}
};


export default function(state = initialState, action) {
  switch (action.type) {
    case GET_ADVANCES:
      return {
        ...state,
        items: action.payload

      };
    case DETAIL_ADVANCE:
      return {
        ...state,
        item: action.payload
      };
    default:
      return state;
  }
}
