ReactNative地址挑选器功能实现方法

产品经理：“你明白吧，这里向右划可以出菜单，然后需要一个闪烁的动画，还有，我想这个tab可以拉下来，你懂吧？

设计师：“别废话，把你要抄的产品给我看下。”

…

接下来，我们仿一下别人家的地址挑选器

import React, { Component, PropTypes } from 'react';
import {
 ViewPropTypes,
 StyleSheet,
 View,
 TouchableOpacity,
 TouchableNativeFeedback,
 Platform,
 Animated,
 Text
} from 'react-native';

export default class SelectCityTabBar extends Component {
 //属性声名
 static propTypes = {
  goToPage: PropTypes.func,
  activeTab: PropTypes.number,
  tabs: PropTypes.array,
  backgroundColor: PropTypes.string,
  activeTextColor: PropTypes.string,
  inactiveTextColor: PropTypes.string,
  textStyle: Text.propTypes.style,
  tabStyle: ViewPropTypes.style,
  renderTab: PropTypes.func,
  underlineStyle: ViewPropTypes.style,
 };
 //默认属性
 static defaultProps = {
  activeTextColor: '#FA3D4F',
  inactiveTextColor: 'black',
  backgroundColor: null,
 }

 renderTab(name, page, isTabActive, onPressHandler) {
  const { activeTextColor, inactiveTextColor, textStyle, } = this.props;
  const textColor = isTabActive ? activeTextColor : inactiveTextColor;
  const fontWeight = isTabActive ? 'bold' : 'normal';
  const viewStyle = isTabActive ? [styles.tab, { borderBottomWidth: Constant.sizepiderLarge, borderColor: Constant.colorPrimary }] : styles.tab;

  if (Platform.OS !== 'ios') {
   return <TouchableNativeFeedback
    delayPressIn={0}
    background={TouchableNativeFeedback.SelectableBackground()}
    key={name + page}
    accessible={true}
    accessibilityLabel={name}
    accessibilityTraits='button'
    onPress={() => onPressHandler(page)}
   >
    <View style={viewStyle}>
     <Text style={[{ color: textColor, fontWeight, }, textStyle,]}>
      {name}
     </Text>
    </View>
   </TouchableNativeFeedback>
  }

  return <TouchableOpacity
   key={name + page}
   accessible={true}
   accessibilityLabel={name}
   accessibilityTraits='button'
   onPress={() => onPressHandler(page)}
  >
   <View style={viewStyle}>
    <Text style={[{ color: textColor, fontWeight, }, textStyle,]}>
     {name}
    </Text>
   </View>
  </TouchableOpacity>;
 }

 render() {
  return (
   <View style={{ flexDirection: 'row', borderBottomWidth: Constant.sizepiderNormal, borderColor: Constant.colorpider }}>
    {this.props.tabs.map((name, page) => {
     const isTabActive = this.props.activeTab === page;
     const renderTab = this.props.renderTab || this.renderTab;
     return this.renderTab(name, page, isTabActive, this.props.goToPage);
    })}
   </View>
  );
 }
}



const styles = StyleSheet.create({
 tab: {
  alignItems: 'center',
  justifyContent: 'center',
  paddingBottom: 10,
  marginLeft: 10,
 },
 tabs: {
  height: 50,
  flexDirection: 'row',
  justifyContent: 'space-around',
  borderWidth: 1,
  borderTopWidth: 0,
  borderLeftWidth: 0,
  borderRightWidth: 0,
  borderColor: '#ccc',
 },
});

npm react-native-scrollable-tab-view 组件

使用方法：

import React, {Component} from 'react';
import {
 StyleSheet,
 View,
 TouchableOpacity,
 Alert,
 ScrollView,
 ART,
 TouchableHighlight,
 ListView,
 Dimensions,
 Text
} from 'react-native';

import {ReactNavComponent, Widget} from 'rn-yunxi';
import AddressSelect from '../../app-widget/address-select/index'

export default class extends React.Component {

 render() {
  return (
   <TouchableOpacity style={{flex:1, justifyContent:'center', alignItems:'center'}} onPress={() => this.openAddressSelect()}>
    <Text >地址选择</Text>
   </TouchableOpacity>
  );

 }

 openAddressSelect() {

  Widget.Popup.show( // 这边使用自己封装的modal嵌套地址选择器
   <AddressSelect
    commitFun={(area) => this.onSelectArea(area)}
    dissmissFun={() => Widget.Popup.hide()}
   />,
   {
    animationType: 'slide-up', backgroundColor: '#00000000', onMaskClose: () => {
    Widget.Popup.hide()
   }
   })
 }

 onSelectArea = (area) => {
  Log(area)
 }
};
