react实现汉堡_reactjs – 所有顶级屏幕标题(使用抽屉)标题中的react-navigation汉堡包图标？...
我可以为某些内容设置“通用”标题选项,例如将标题颜色设置为白色：
// example screens
const SettingsScreen = () => SettingsScreen...
const List = () => List...
const Item = () => Item...
// create an object to pass on to relevant screens
const navigationOptions = {
header: {
style: {
backgroundColor: '#fff'
}
},
}
// MAIN SCREEN : a screen showing a list with ability to click on an list item and go to a detail page
// ============================
const ListScreens = StackNavigator({
List: { screen: List, navigationOptions: navigationOptions }, //show a hamburger menu
Item: { screen: Item, navigationOptions: navigationOptions }, // this is a detail page, so don not show a hamburger menu, rather show a back button
});
const SettingsContainer = StackNavigator({
Settings: { screen: SettingsScreen },
});
// LOGGED IN DRAWER VIEW : top-level component is a drawer with two menu items (main and settings)
// ============================
const LoggedIn = DrawerNavigator({
Main: { screen: ListScreens },
Settings: { screen: SettingsContainer },
});
//... do stuff for root component
在DrawerNavigation菜单级别为所有路线添加汉堡菜单的最佳做法是什么？我想让这个流行音乐打开抽屉.没有访问props.navigation,除非我在每个组件内部……只是状态和参数.我是否需要复制每个文件中的代码？
static navigationOptions = {
title: ({ state }) => {
if (state.params.mode === 'info') {
return `${state.params.user}'s Contact Info`;
}
return `Chat with ${state.params.user}`;
},
header: ({ state, setParams }) => {
// The navigation prop has functions like setParams, goBack, and navigate.
let right = (
title={`${state.params.user}'s info`}
onPress={() => setParams({ mode: 'info' })}
/>
);
if (state.params.mode === 'info') {
right = (
title="Done"
onPress={() => setParams({ mode: 'none' })}
/>
);
}
return { right };
},
..
相关问题(可能)：
最佳答案 我创建了自己的标题：
{this._drawer.openDrawer()}}>
{'TITLE'}
如上所述,我正在使用openDrawer()事件,我在组件中引用了该事件：
ref={(drawer) => {this._drawer = drawer}}

我不得不删除默认标头：
export default class HomeScreen extends Component {
static navigationOptions = {
header: null
};
