# React Native 游戏屏幕开发详解
## 1. InfoScreen 组件分析
### 1.1 样式定义
InfoScreen 组件的样式定义如下:
```javascript
const styles = StyleSheet.create({
outerContainer :
{ justifyContent : "center", marginTop : 50, marginLeft : 20,
marginRight : 20 },
identificationCardContainer : { height : 150, marginBottom : 20 },
currentGameCardContainer : { height : 360 },
headerText : { fontWeight : "bold", fontSize : 20, color : "red" },
fieldContainer : { flexDirection : "row" },
fieldLabel : { width : 100, fontWeight : "bold" },
fieldSpacing : { marginBottom : 12 }
});
```
### 1.2 组件代码
组件代码如下:
```javascript
class InfoScreen extends React.Component {
constructor(inProps) {
super(inProps);
}
render() {
return (
<View style={styles.outerContainer}>
<View style={styles.identificationCardContainer}>
<Card>
<CardItem header>
<Text style={styles.headerText}>Identification</Text>
</CardItem>
<CardItem>
<Body>
<View style={styles.fieldContainer}>
<Text style={styles.fieldLabel}>Player Name</Text>
<Text>{this.props.playerName}</Text>
</View>
<View style={styles.fieldContainer}>
<Text style={styles.fieldLabel}>Player ID</Text>
<Text>{this.props.playerID}</Text>
</View>
</Body>
</CardItem>
</Card>
</View>
<View style={styles.currentGameCardContainer}>
<Card>
<CardItem header>
<Text style={styles.headerText}>Current Game</Text>
</CardItem>
<CardItem>
<Body>
<View style={[ styles.fieldContainer, styles.fieldSpacing ]}>
<Text style={styles.fieldLabel}>Asked</Text>
<Text>{this.props.asked}</Text>
</View>
<View style={[ styles.fieldContainer, styles.fieldSpacing ]}>
<Text style={styles.fieldLabel}>Answered</Text>
<Text>{this.props.answered}</Text>
</View>
<View style={[ styles.fieldContainer, styles.fieldSpacing ]}>
<Text style={styles.fieldLabel}>Points</Text>
<Text>{this.props.points}</Text>
</View>
<View style={[ styles.fieldContainer, styles.fieldSpacing ]}>
<Text style={styles.fieldLabel}>Right</Text>
<Text>{this.props.right}</Text>
</View>
<View style={[ styles.fieldContainer, styles.fieldSpacing ]}>
<Text style={styles.fieldLabel}>Wrong</Text>
<Text>{this.props.wrong}</Text>
</View>
<View style={[ styles.fieldContainer, styles.fieldSpacing ]}>
<Text style={styles.fieldLabel}>Total Time</Text>
<Text>{this.props.totalTime}</Text>
</View>
<View style={[ styles.fieldContainer, styles.fieldSpacing ]}>
<Text style={styles.fieldLabel}>Slowest</Text>
<Text>{this.props.slowest}</Text>
</View>
<View style={[ styles.fieldContainer, styles.fieldSpacing ]}>
<Text style={styles.fieldLabel}>Fastest</Text>
<Text>{this.props.fastest}</Text>
</View>
<View style={ styles.fieldContainer }>
<Text style={styles.fieldLabel}>Average</Text>
<Text>{this.props.average}</Text>
</View>
</Body>
</CardItem>
</Card>
</View>
</View>
);
}
}
```
### 1.3 组件功能
InfoScreen 组件主要包含两个卡片,一个用于显示玩家的身份信息,另一个用于显示当前游戏的相关数据。使用了 NativeBase 的 Card 组件,它是一个灵活且可扩展的内容容器,具有阴影效果和自动间距功能。组件通过 `mapStateToProps()` 函数将 Redux 状态树中的数据映射到组件的 props 上。
### 1.4 数据映射
| 组件属性 | 状态树映射 |
| ---- | ---- |
| playerName | playerInfo.name |
| playerID | playerInfo.id |
| asked | gameData.asked |
| answered | gameData.answered |
| points | gameData.points |
| right | gameData.right |
| wrong | gameData.wrong |
| totalTime | gameData.totalTime |
| slowest | gameData.slowest |
| fastest | gameData.fastest |
| average | gameData.average |
