代码：

import React, {Component} from 'react'
import {StyleSheet, View, Text, TouchableOpacity, TextInput} from 'react-native'

class TextInputView extends Component {

    constructor(popps) {
        super(popps);
        this.state = {
            text: ''
        }

    }

    hide(val) {
        this.setState({
            show: false, value: val
        })
    }

    getValue(text) {
        var value = text;
        this.setState({
            show: true, value: value
        })
    }

    render() {

        return (
            <View style={styles.container} accessible={true}>
                <TextInput style={styles.styleInput}
                           returnKeyLabel={"search"}
                           placeholder={"请输入搜索的关键字"}
                           onEndEditing={this.hide.bind(this, this.state.value)}
                           onChangeText={this.getValue.bind(this)}
                />

                <Text style={styles.styleText}>搜索结果</Text>
                {this.state.show ?
                    <View style={[styles.styleResult]}>
                        <Text onPress={this.hide.bind(this, this.state.value + "街")} style={styles.item}
                              numberOfLines={1}>
                            {this.state.value}街
                        </Text>
                        <Text onPress={this.hide.bind(this,this.state.value+"车站")} style={styles.item}
                        numberOfLines={1}>
                            {this.state.value}车站
                        </Text>
                    </View> : null
                }

            </View>
        );
    }

}

const styles = StyleSheet.create({
    container: {
        flex: 1,backgroundColor: '#ffffff',marginTop: 20
    },
    styleInput: {
        height:40,borderWidth: 1,marginLeft: 10,marginRight: 10,paddingLeft: 5,borderColor:'#cccccc',borderRadius:4
    },
    styleResult:{
        marginLeft:15,marginTop:10
    },
    styleText: {
        fontSize: 16,marginTop: 10,marginLeft:15
    },
    styleItem: {
        fontSize:18,padding: 5,paddingTop: 10,paddingBottom: 10,marginLeft: 15,borderColor: '#dddddd',borderTopWidth: 0
    }

});
