react导航的DrawerNavigator在drawer close上调用什么函数

Question

我想在抽屉时派发一个动作close.But我不知道我需要写什么功能，你能帮我吗

Answer 1

您需要自定义导航操作才能知道 DrawerClose 事件 fired.Here 是一个简单的示例：

const MyAppDrawerNavigator = DrawerNavigator({
    //...
});

const defaultGetStateForAction = MyAppDrawerNavigator.router.getStateForAction;

MyAppDrawerNavigator.router.getStateForAction = (action, state) => {

    if (state && action.type === 'Navigation/NAVIGATE' && action.routeName === 'DrawerClose') {
        console.log('DrawerClose');
        //dispatch whatever action you want
    }
    return defaultGetStateForAction(action, state);
};
