+title: 主题配置
+spline: explain
+---
+
+### 使用主题
+
+在根组件外层添加`ThemeProvider`组件，在需要使用主题的组件中使用`useTheme`hook，获取到主题，使用对应token即可。
+
+```js
+import { ThemeProvider } from '@src/theme';
+
+function App() {
+    return (
+        <ThemeProvider>
+            <Root/>
+        </ThemeProvider>
+    )
+}
+
+import { useTheme } from '@src/theme';
+function Root() {
+    const { theme } = useTheme();
+    return <Text style={{color: theme.colors.fontGray1}}>测试</Text>
+}
+```
+
+### 使用className
+
+组件提供类似`Tailwind CSS`的便捷样式功能，需要配合组件库提供的View、Text等组件共同使用。可以查看`tdesign-react-native/src/theme/light/classnames.ts`支持哪些样式。
+
+```js
+import { Text, ScrollView, View, Button } from '@src/components';
+
+function Demo() {
+    return <View className="bg mt12">
+        <Text className="text4">测试</Text>
+    </View>
+}
+
+```
+
+### 自定义样式
+
+`ThemeProvider`组件接收`config`参数可以配置一些自定义样式或覆盖已有样式。
+
+```js
+<ThemeProvider config={{
+    light: {
+        // 覆盖样式
+        colors: {
+            fontGray2: 'red',
+        },
+        classnames: {
+            // 自定义样式
+            testBg: {
+                backgroundColor: 'red',
+            },
+        },
+    },
+    }}
+></ThemeProvider>
+
+function Demo() {
+    return <View className="testBg">
+        <Text className="fontGray2">测试</Text>
+    </View>
+}
+```
