ios – 在React Native中设置ListView的高度

我需要设置ListView的宽度和高度.当设置宽度按预期工作时,设置高度无效,ListView总是伸展到屏幕的几乎底部(屏幕的bootom和ListView的底部之间只有边距).我用这种方式在render方法中创建ListView：

<ListView ref={component => this._stationsListFrom = component} style={styles.stationsList} dataSource={this.state.dataSource} renderRow={(rowData) => <Text>{rowData}</Text>} />

这是它的风格：

stationsList: {
  backgroundColor: 'white',height: 0,}

我还尝试通过此命令在方法中设置其高度：

this._stationsListFrom.setNativeProps({height: 200});

当我尝试使用此命令设置宽度时,它可以工作.但设定高度什么都不做.

如何将ListView的高度(例如,在TextInput的情况下,它不是一个问题)设置为所需的值？我唯一的方法是使用底部边距,但这不是我想要使用的方式.

我只在iOS上测试(因为它在Android上的工作方式不同).

我的代码：

import React,{ Component } from 'react';
import Dimensions from 'Dimensions';
import {
  AppRegistry,StyleSheet,Text,TextInput,ListView,Button,View
} from 'react-native';

const styles = StyleSheet.create({
  container: {
    flex: 1,justifyContent: 'flex-start',alignItems: 'flex-start',backgroundColor: '#D8CD36',padding: 25
  },label: {
    textAlign: 'left',color: '#333333',fontSize: 20,margin: 5,},textInput: {
    height: 40,borderColor: 'black',borderWidth: 2,padding: 7,stationsList: {
    backgroundColor: 'white',separator: {
    flex: 1,height: StyleSheet.hairlinewidth,backgroundColor: '#8E8E8E',menuButton: {
  },);

export default class TestApp extends Component {

  constructor(props) {
    super(props);

    const ds = new ListView.DataSource({rowHasChanged: (r1,r2) => r1 !== r2}); this.state = { dataSource: ds.cloneWithRows(['Žilina','Košice','Vrútky']),};
  }

  render() {
    return (
      <View style={styles.container}>
        <Text style={styles.label}>
            Z
        </Text>
        <TextInput ref={component => this._textInputFrom = component} style={styles.textInput} placeholder="Východzia stanica" onChangeText={this.fromTextChange.bind(this)} onLayout={(event) => { this.correctMenuFromWidth(event.nativeEvent.layout) }} renderSeparator={(sectionId,rowId) => <View key={rowId} style={styles.separator}/>} />
        <Text style={styles.label}>
            Do
        </Text>
        <TextInput style={styles.textInput} placeholder="Cieľová stanica"/>
        <ListView ref={component => this._stationsListFrom = component} style={styles.stationsList} dataSource={this.state.dataSource} renderRow={(rowData) => <Button onPress={this.menuFromButtonpressed} style={styles.menuButton} title={rowData} />} />
      </View>
    );
  }

  correctMenuFromWidth(layout) {
    const {x,y,width,height} = layout;
    this._stationsListFrom.setNativeProps({marginTop: -74,width: width});
  }

  menuFromButtonpressed() {
  };

  fromTextChange() {
    this._textInputFrom.setNativeProps({text: 'Kraľovany'});
    this._stationsListFrom.setNativeProps({height: 200});
  };

}

AppRegistry.registerComponent('TestApp',() => TestApp);

<View style={{height: 200}}>
  <ListView .../>
</View>
