描述

嘿！我不确定这是否算作一个bug,但我在触摸事件处理中可能遗漏了一些功能。目前，在Android touchMove 中，当原生手势被识别并在子组件中拦截时，事件似乎会被取消。在查看您的源代码后，我注意到这是故意在JSTouchDispatcher.java中完成的：

public void onChildStartedNativeGesture(
      MotionEvent androidEvent, EventDispatcher eventDispatcher) {
    if (mChildIsHandlingNativeGesture) {
      // This means we previously had another child start handling this native gesture and now a
      // different native parent of that child has decided to intercept the touch stream and handle
      // the gesture itself. Example where this can happen: HorizontalScrollView in a ScrollView.
      return;
    }

    dispatchCancelEvent(androidEvent, eventDispatcher);
    mChildIsHandlingNativeGesture = true;
    mTargetTag = -1;
  }

我仍然希望在手势开始和结束时接收touchMove和特定的touchEnd事件。但是，现在我只会遇到几个touchMove事件和touchCancelled。实现起来似乎并不困难，但也许有原因为什么选择这种方法？

重现步骤

1. 简单初始化应用程序 npx react-native@latest init AwesomeProject22
2. 在顶层视图上添加一个简单的onTouchMove onTouchMove={()=>console.log("moving")}
3. 用 npx react-native run-android运行应用程序
4. 尝试触发touch move事件。当向两边移动时，一切似乎都正常。当你开始拖动到顶部或底部时，只会触发几个touchMove事件，然后在下一个touchStart事件之前被取消。
