我正在使用tcomb-form-native(https://github.com/gcanti/tcomb-form-native)模块在React Native中创建表单。此模块提供布尔类型的输入,它呈现Switch组件(https://facebook.github.io/react-native/docs/switch.html)。
我不确定实现这一目标的最佳方法是什么?使用开关组件?使用一个触发真正开关的假组件(会被隐藏)?
答案 0 :(得分:1)
我认为一个好方法是制作一个自定义工厂我做了一次自定义开关,我会在这里发布。我没有修改Switch的外观,但我相信你可以创建一个看起来像你的图像的组件,然后在你的工厂中使用它。在我的情况下,我将一些文本与交换机对齐,并带有可点击的链接,依此类推。我没有尝试过,但我想你可以用你自己的替换Switch组件。
import React from 'react';
import { View, Text, Switch, TouchableOpacity } from 'react-native';
import t from 'tcomb-form-native';
import Strings from '../config/strings.js';
var Component = t.form.Component;
class TermsSwitch extends Component {
constructor (props) {
super(props);
var locals = super.getLocals();
}
getLocals () {
var locals = super.getLocals();
return locals;
}
getTemplate () {
return function (locals) {
var stylesheet = locals.stylesheet;
var formGroupStyle = stylesheet.formGroup.normal;
var controlLabelStyle = stylesheet.controlLabel.normal;
var checkboxStyle = stylesheet.checkbox.normal;
var helpBlockStyle = stylesheet.helpBlock.normal;
var errorBlockStyle = stylesheet.errorBlock;
if (locals.hasError) {
formGroupStyle = stylesheet.formGroup.error;
controlLabelStyle = stylesheet.controlLabel.error;
checkboxStyle = stylesheet.checkbox.error;
helpBlockStyle = stylesheet.helpBlock.error;
}
var label = locals.label ? <Text style={controlLabelStyle}>{locals.label}</Text> : null;
var help = locals.help ? <Text style={helpBlockStyle}>{locals.help}</Text> : null;
var error = locals.hasError && locals.error ? <Text accessibilityLiveRegion="polite" style={[errorBlockStyle, {marginTop: 2}]}>{locals.error}</Text> : null;
return (
<View style={formGroupStyle}>
{label}
<View style={{flexDirection: 'row', alignItems: 'center'}}>
<View style={{flexDirection: 'row', flexWrap: 'wrap', alignItems: 'center'}}>
<Text style={{fontSize: 14}}>Jag har läst och accepterar </Text>
<TouchableOpacity onPress={() => locals.config.onPressTerms()}>
<Text style={{fontStyle: 'italic', fontSize: 14, textDecorationLine: 'underline'}}>villkoren</Text>
</TouchableOpacity>
</View>
<View style={{flex: 1, flexDirection: 'column', justifyContent: 'center', paddingTop: 6}}>
<Switch
accessibilityLabel={locals.label}
ref="input"
disabled={locals.disabled}
onTintColor={locals.onTintColor}
thumbTintColor={locals.thumbTintColor}
tintColor={locals.tintColor}
style={checkboxStyle}
onValueChange={(value) => locals.onChange(value)}
value={locals.value} />
</View>
</View>
{help}
{error}
</View>
);
}
}
}
export default TermsSwitch
然后使用你的工厂:
const options = {
fields: {
your_switch: {
config: {
onPressTerms: () => {
...
},
},
factory: TermsSwitch,
stylesheet: stylesheet,
},
...
},
}
我希望这可以帮到你!
祝你好运!
