react-native - React-native-gesture-handler 有问题（找不到符号字符串溢出 = ((ReactViewGroup) view).getOverflow();)

问题描述

我有一个问题react-native-gesture-handler。每当我将我的项目链接react-native-gesture-handler到我的项目时，它就会停止工作并显示此错误。但是react-native-gesture-handler从我的项目中取消链接后，应用程序工作正常。但由于我需要从多个屏幕导航，我需要手势处理程序。

首先，我认为这是react-native版本的问题，因为我使用react-native的是 0.57.0 版本，但它也不适用于 0.58.0 和 0.55.4。

package com.swmansion.gesturehandler.react;

import android.os.Build;
import android.view.View;
import android.view.ViewGroup;

import com.facebook.react.uimanager.PointerEvents;
import com.facebook.react.uimanager.ReactPointerEventsView;
import com.facebook.react.views.view.ReactViewGroup;
import com.swmansion.gesturehandler.PointerEventsConfig;
import com.swmansion.gesturehandler.ViewConfigurationHelper;

public class RNViewConfigurationHelper implements ViewConfigurationHelper {

  @Override
  public PointerEventsConfig getPointerEventsConfigForView(View view) {
    PointerEvents pointerEvents;
    pointerEvents = view instanceof ReactPointerEventsView ?
            ((ReactPointerEventsView) view).getPointerEvents() :
            PointerEvents.AUTO;

    // Views that are disabled should never be the target of pointer events. However, their children
    // can be because some views (SwipeRefreshLayout) use enabled but still have children that can
    // be valid targets.
    if (!view.isEnabled()) {
      if (pointerEvents == PointerEvents.AUTO) {
        return PointerEventsConfig.BOX_NONE;
      } else if (pointerEvents == PointerEvents.BOX_ONLY) {
        return PointerEventsConfig.NONE;
      }
    }

    switch (pointerEvents) {
      case BOX_ONLY: return PointerEventsConfig.BOX_ONLY;
      case BOX_NONE: return PointerEventsConfig.BOX_NONE;
      case NONE: return PointerEventsConfig.NONE;
    }

    return PointerEventsConfig.AUTO;
  }

  @Override
  public View getChildInDrawingOrderAtIndex(ViewGroup parent, int index) {
    if (parent instanceof ReactViewGroup) {
      return parent.getChildAt(((ReactViewGroup) parent).getZIndexMappedChildIndex(index));
    }
    return parent.getChildAt(index);
  }

  @Override
  public boolean isViewClippingChildren(ViewGroup view) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR2 && !view.getClipChildren()) {
        if (view instanceof ReactViewGroup) {
            String overflow = ((ReactViewGroup) view).getOverflow();
            return "hidden".equals(overflow);
        }
        return false;
      }
    return true;
  }
}
