  我能够确定应用程序是通过后退按钮返回还是使用路由器的getStateForAction函数向后滑动 . 如果需要，可以检查动作和状态变量以进一步微调 .

  export const ScreensStack = StackNavigator(
  {
      Login: {screen: LoginScreen},
      Schedule: {screen: ScheduleScreen},
  }
  
  /**
   * Intercept actions occuring in the screen stack.
   */
  const getStateForActionScreensStack = ScreensStack.router.getStateForAction;
  
  ScreensStack.router = {
      ...ScreensStack.router,
      getStateForAction(action, state) {
        if action.type == 'Navigation/BACK') {
          console.log('We are going back...');
        }
        return getStateForActionScreensStack(action, state);
      },
  };
