listview - react native : ListView item does not scale full width

Question

我用一个简单的文本项创建了一个简单的 ListView 组件。

import React from "react";
import { StyleSheet, Text, View, ListView } from "react-native";

export default class NoteList extends React.Component {
  constructor(props) {
    super(props);
    this.ds = new ListView.DataSource({
      rowHasChanged: (r1, r2) => {
        r1 !== r2;
      }
    });
  }

  render() {
    return (
      <ListView
        dataSource={this.ds.cloneWithRows([
          { title: "Note 1", body: "Body 1", id: 1 },
          { title: "Note 2", body: "Body 2", id: 2 }
        ])}
        renderRow={rowData => {
          return (
            <View style={styles.itemContainer}>
              <Text style={styles.itemText}>
                {rowData.title}
              </Text>
            </View>
          );
        }}
      />
    );
  }
}

const styles = StyleSheet.create({
  itemContainer: {
    flex: 1,
    flexDirection: "row",
    justifyContent: "flex-start",
    borderColor: "red",
    borderWidth: 1
  },

  itemText: {
    padding: 16,
    borderColor: "blue",
    borderWidth: 1
  }
});

我为文本使用包装 View 。然后使用 FlexBox 将文本缩放到全宽并将其内容左对齐。但是当文本居中对齐并包装内容(包装 View 也包装内容)时，结果并不像预期的那样。如何解决这个问题？

您也可以使用 Dimensions 获取屏幕宽度并分配给 text

从 react-native 导入维度

import { StyleSheet, Text, View, ListView, Dimensions } from "react-native";

将宽度分配给文本:

itemText: {
    padding: 16,
    borderColor: "blue",
    borderWidth: 1,
    width: (Dimensions.get('window').width)
  }
