java - React Native - 如何将可读数组从 React Native 映射到 Android 中的 native 模块？

Question

我有一个 react native 代码。我用它来将数组传递给 native 模块，并且我想在 native 模块上处理它，

ReadableArray 示例:

{"AuditScheduleDetailID":5525,"AuditAnswerId":33,"LocalFindingID":1,"LocalMediaID":1,"ExtFiles":"jpg"}

我想获取里面键的每个值 - 我该怎么做？

我已经尝试过this article但我不太明白。

我现在只是像这样硬编码它:

@ReactMethod
public void insert(ReadableArray name, String file) {
    DatabaseHandler db = new DatabaseHandler(getReactApplicationContext());
    String a = "path to file";
    for(int i=0 ; i<name.size(); i++){
    //expected result
    int audit  = 5525 //from AuditScheduleDetailID value
    int answer = 33 // from AuditAnswerId value
    int finding = 1 // from LocalFindingID value
    int media = 1 // from LocalMediaID value
    String exten = "jpg" // from ExtFiles value
    db.addContact(new Contact(audit, answer, finding, media, exten));
    }
}

有没有办法从可读数组key中获取每个值？

在 javascript 上，您调用此方法只是作为对象传递

import { NativeModules } from 'react-native';

NativeModules.<<ModuleName>>.insert({"AuditScheduleDetailID":5525,"AuditAnswerId":33,"LocalFindingID":1,"LocalMediaID":1,"ExtFiles":"jpg"}, <<fileName>>);

修改您的 react 方法以接受 ReadableMap 而不是 ReadableArray

@ReactMethod
public void insert(ReadableMap readableMap, String file) {
  String auditScheduleDetailID = readableMap.getString("AuditScheduleDetailID");
  String auditAnswerId = readableMap.getString("AuditAnswerId");
  String localFindingID = readableMap.getString("LocalFindingID");
  String localMediaID = readableMap.getString("LocalMediaID");
  String extFiles = readableMap.getString("ExtFiles");
  //your logic
}
