javascript - React-native，react-native-router-flux && 抽屉上的自定义图标不起作用

Question

直到现在它呈现但没有打开抽屉。

我相信是与参考相关的东西，但我不确定。

如果有人可以帮助我，那就太棒了。

我所做的是以nativebase及其示例为基础的。

添加 Redux

抽屉动作.js

import type { Action } from './types';

const OPEN_DRAWER = 'open_drawer';
const CLOSE_DRAWER = 'close_drawer';

export function openDrawer():Action {
  return {
    type: OPEN_DRAWER,
  };
}

export function closeDrawer():Action {
  return {
    type: CLOSE_DRAWER,
  };
}

抽屉减速器.js

import type { Action } from '../actions/types';

export const OPEN_DRAWER = 'open_drawer';
export const CLOSE_DRAWER = 'close_drawer';

export type State = {
    drawerState: string,
    drawerDisabled: boolean
}

const initialState = {
  drawerState: 'closed',
  drawerDisabled: true,
};

export default function (state:State = initialState, action:Action): State {
  if (action.type === OPEN_DRAWER) {
    return {
      ...state,
      drawerState: 'opened',
    };
  }

  if (action.type === CLOSE_DRAWER) {
    return {
      ...state,
      drawerState: 'closed',
    };
  }

  return state;
}

使用 react-redux 我连接了sideDrawer.js组件 import React, { Component, PropTypes } from 'react'; 从'react-redux'导入{连接}；

import {
  BackAndroid,
  StyleSheet,
  Text,
  View,
} from 'react-native';
import { Drawer } from 'native-base';

import { DefaultRenderer, Actions } from 'react-native-router-flux';
import SideBar from './sidebar';
import { closeDrawer } from '../actions';

const propTypes = {
  navigationState: PropTypes.object,
};

class SideDrawer extends Component {
  static propTypes = {
    closeDrawer: React.PropTypes.func,
    drawerState: React.PropTypes.string,
  }

  constructor(props) {
    super(props);
    this.state = {
      animatingLoadingSpinner: false,
      url: 'polls',
    };
  }

  componentDidMount() {
    BackAndroid.addEventListener('hardwareBackPress', () => {
      Actions.pollCreation();
    });
    Actions.refresh({ key: 'drawer', ref: this.refs.navigation });
  }

  componentDidUpdate() {
    if (this.props.drawerState === 'opened') {
      this.openDrawer();
    }

    if (this.props.drawerState === 'closed') {
      this.refs.navigation.close();
    }
  }

  openDrawer() {
    this.refs.navigation.open();
  }

  closeDrawer() {
    console.log(`onClose: ${this.props.drawerState}`);

    if (this.props.drawerState === 'opened') {
      this.props.closeDrawer();
    }
  }

  finishSpinnerAnimation() {
    this.setState({
      animatingLoadingSpinner: false
    });
  }

  startSpinnerAnimation() {
    this.setState({
      animatingLoadingSpinner: true
    });
  }


  noServerConnection() {
    return (
      <View style={styles.errorBody} >
        <Text > No es posible la conexión con Nuestros servidores </Text>
      </View>
    );
  }

  render() {
    const state = this.props.navigationState;
    const children = state.children;
    return (
      <View style={styles.container} >
        <Drawer
          ref='navigation'
          type="overlay"
          tweenDuration={150}
          content={
            <SideBar
              closeDrawer={() => this.closeDrawer()}
            />
          }
          tapToClose
          acceptPan={false}
          openDrawerOffset={0.2}
          panCloseMask={0.2}
          styles={{
            drawer: {
              shadowColor: '#000000',
              shadowOpacity: 0.8,
              shadowRadius: 3,
            },
          }}
          tweenHandler={(ratio) => {  // eslint-disable-line
            return {
              drawer: { shadowRadius: ratio < 0.2 ? ratio * 5 * 5 : 5 },
              main: {
                opacity: (2 - ratio) / 2,
              },
            };
          }}
          negotiatePan
          onCloseStart={this.closeDrawer.bind(this)}
        >
          <DefaultRenderer navigationState={children[0]} onNavigate={this.props.onNavigate} />
        </Drawer>
      </View>
    );
  }

}

const BGWASH = '#F6F6F6';

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: BGWASH,
  },
  addressBarRow: {
    flexDirection: 'row',
    height: 10,
  },
  errorBody: {
    alignItems: 'center',
    justifyContent: 'center',
  },
  navButton: {
    alignItems: 'flex-end',
    flex: 1,
  },
  navText: {
    fontSize: 18,
  },
  navTextContainer: {
    alignItems: 'center',
    flex: 8,
    justifyContent: 'center',
  },
});

SideDrawer.propTypes = propTypes;
const mapStateToProps = (state) => {
  const { url } = state.polls;
  const drawerState = state.drawer.drawerState;
  return { drawerState, url };
};
const mapDispatchToProps = dispatch => ({
  closeDrawer: () => dispatch(closeDrawer()),
});

export default connect(mapStateToProps, mapDispatchToProps)(SideDrawer);

也连接tabIcon.js，它会负责在点击时打开抽屉。

import React, {
  Component,
  PropTypes,
  StyleSheet
} from 'react';

import {
  Text,
} from 'react-native';

import MaterialIcons from 'react-native-vector-icons/MaterialIcons';
import { Button } from 'native-base';
import { Actions } from 'react-native-router-flux';
import { connect } from 'react-redux';
import { openDrawer } from '../actions';

const propTypes = {
  selected: PropTypes.bool,
  title: PropTypes.string,
};

class TabIcon extends Component {
  openDrawer = () => {
    this.props.openDrawer();
    // Actions.refresh({ key: 'drawer', open: value => !value });
  };
  render() {
    return (
      <Button
        transparent
        onPress={this.openDrawer.bind(this)} style={styles.navButton}
        style={{ backgroundColor: 'rgba(0,0,0,0)' }}
      >
        <Text>
          <MaterialIcons name="menu" size={30} />
        </Text>
      </Button>
    );
  }
}
TabIcon.propTypes = propTypes;

const styles = {
  navButton: {
    alignItems: 'flex-end',
    flex: 1,
  }
};

export default connect(null, { openDrawer })(TabIcon);
