2 years ago 这是react native的版本问题。你说反了，0.60之前是数字，0.60后rn已经弃用数字改为字符串了。详见这个方法
/**

* for a {@link ScrollView} instance.
*
* <p>This method is deprecated use {@link #receiveCommand(View, String, ReadableArray)} instead.
*
* @param root View instance that should receive the command
* @param commandId code of the command
* @param args optional arguments for the command

@Deprecated
public void receiveCommand(@NonNull T root, int commandId, @Nullable ReadableArray args) {}
/**

public void receiveCommand(@NonNull T root, String commandId, @Nullable ReadableArray args) {}而且在我的SpringScrollView中也明确写了0.60以下不推荐使用最新版本,只是largelist文档上忘记写了:
React Native版本推荐：
react-native@0.50以下：不确定是否支持，请自行解决原生端问题。
react-native@0.50-0.59：推荐使用react-native-spring-scrollview@2.0.* (最后一位版本号可自行去npm官方查询最新发布的版本)
react-native@0.60+：推荐使用react-native-spring-scrollview@3.0+
1 、Mac, Android, Simulator and real device, rn0.59.9, "react-native-spring-scrollview": "version": "3.0.1-rc.5",
2、安卓端使用官方largelist demo，点击某一行后调用scrollTo方法报红屏错误。错误见图片。导致问题的原因是SpringScrollView.js中scrollTo方法调用UIManager.dispatchViewManagerCommand第二个参数“10002”是字符串，rn 0.59.9及之后的版本中（0.59.9之前的版本没有确认）原生类中该方法的第二个参数是int类型，所以出现了红屏错误，手动修改成int数字后就没问题了。出现了该红屏错误后，demo中左边的按钮无法再点击。
