我有一个带有主题的TextView，ActionButtonBlue。如何在运行时将TextView的import React, { Component } from 'react';
import LocalesProvider from './Providers/LocalesProvider.js';
import { NavLink, HashRouter } from "react-router-dom";
class Sidebar extends Component
{
constructor(props) {
super(props);
}
buildLocaleLinks (locales, uri) {
if (!this.props.isReady) {
return 'Loading...';
}
if (!locales.length) {
return null;
}
return locales.map(function (locale) {
return (
<li key={'navigation.translate.' + locale.props.key}>
<NavLink replace to={'/' + uri + '/' + locale.props.key}>
{locale.props.key}
</NavLink>
</li>
);
})
}
render () {
return (
<HashRouter>
<aside className="menu">
<p className="menu-label">
Menu
</p>
<ul className="menu-list">
<li>Translate</li>
<li>
<ul>
<LocalesProvider.Consumer>
{locales => (
this.buildLocaleLinks(locales, 'translate')
)}
</LocalesProvider.Consumer>
</ul>
</li>
<li>Validate</li>
<li>
<ul>
<LocalesProvider.Consumer>
{locales => (
this.buildLocaleLinks(locales, 'validate')
)}
</LocalesProvider.Consumer>
</ul>
</li>
</ul>
</aside>
</HashRouter>
);
}
}
export default Sidebar;
从ActionButtonBlue更改为ActionButtonYellow？方法theme适用于setTextAppearance()属性，但不适用于style属性。
themestyles.xml：
<TextView
android:id="@+id/blueTV"
android:theme="@style/ActionButtonBlue"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
答案 0 :(得分：0)
尝试以下代码：
blueTV = (TextView) findViewById(R.id.blueTV);
blueTV = new TextView(getApplicationContext(), null, R.style.ActionButtonBlue);
