java - React Native-如何在Android中将可读数组从React Native映射到Native Module？

我在React Native中有一个代码。我用它将数组传递给本机模块，我想在本机模块上处理它，

ReadableArray的示例：

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

我想获取密钥的每个值-我该怎么做？

我已经尝试过this article，但我不太了解。

我只是现在这样硬编码：

@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readarray value获取每个key？

最佳答案

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
}
