您好我在我的项目中使用json解析。我有以下响应,我将它设置为微调器。
import React, { Component } from 'react';
import {
StyleSheet,
View,
Image
} from 'react-native';
const playIcon = require('./images/play.png');
const volumeIcon = require('./images/sound.png');
const hdIcon = require('./images/hd-sign.png');
const fullScreenIcon = require('./images/full-screen.png');
const remoteImage = { uri:'https://s3.amazonaws.com/crysfel/public/book/new-york.jpg' };
export default class App extends Component<{}> {
render() {
return (
<Image source={remoteImage} style={styles.fullscreen}>
<View style={styles.container}>
<Image source={playIcon} style={styles.icon} />
<Image source={volumeIcon} style={styles.icon} />
<View style={styles.progress}>
<View style={styles.progressBar} />
</View>
<Image source={hdIcon} style={styles.icon} />
<Image source={fullScreenIcon} style={styles.icon} />
</View>
</Image>
);
}
}
const styles = StyleSheet.create({
fullscreen: {
flex: 1,
},
container: {
position: 'absolute',
backgroundColor: '#202020',
borderRadius: 5,
flexDirection: 'row',
height: 50,
padding: 5,
paddingTop: 16,
bottom: 30,
right: 10,
left: 10,
borderWidth: 1,
borderColor: '#303030',
},
icon: {
tintColor: '#fff',
height: 16,
width: 16,
marginLeft: 5,
marginRight: 5,
},
progress: {
backgroundColor: '#000',
borderRadius: 7,
flex: 1,
height: 14,
margin: 10,
marginTop: 2,
},
progressBar: {
backgroundColor: '#bf161c',
borderRadius: 5,
height: 10,
margin: 2,
width: 80,
},
});
现在的问题是我想添加一个id并命名为static。 id:1,name:All
任何人都可以帮我解决这个问题吗?
{"success":1,"languages":[{"id":"2","name":"telugu"},{"id":"3","name":"English"},{"id":"4","name":"Tamil"}]}

从for循环中取出这一行
LanguageModel alldata = new LanguageModel();
alldata.setLangid(("1"));
alldata.setLangname(("All"));
langList.add(0,alldata);
答案 1 :(得分:1)
这里的问题是你在for循环中添加id : 1, name : All
会导致它被多次添加。这应该只添加一次。
从for
循环
LanguageModel alldata = new LanguageModel();
alldata.setLangid(("1"));
alldata.setLangname(("All"));
langList.add(0,alldata);
并放在for
声明之上。
答案 2 :(得分:0)
您正在从循环和填充以及arraylist
获取数据。只需删除此行即可。
LanguageModel alldata = new LanguageModel();
alldata.setLangid(("1"));
alldata.setLangname(("All"));
langList.add(0,alldata);
