我正在构建数字文本输入矩阵,并且由于数字键盘没有返回或下一步按钮而遇到了很多麻烦。另外,数字键盘没有一个Done
栏,所以我不得不使用TouchableWithoutFeedback
组件来处理它的关闭。
我想知道是否有推荐的方法将许多数字无缝输入到 react-native 矩阵中TextInput
?
下面是我的代码,我为容器着色以帮助布置应用程序。
import React from 'react';
import { StyleSheet, Text, View, TextInput, TouchableWithoutFeedback, Keyboard} from 'react-native';
class InputBox extends React.Component {
render() {
return (
<View style={styles.inputContainer}>
<TextInput
keyboardType="numeric"
style={styles.matrixNumberInput}
/>
</View>
)
}
}
export default class App extends React.Component {
constructor(props) {
super(props);
this.state = {'size': 3};
}
render() {
return (
<View style={styles.rootContainer}>
<TouchableWithoutFeedback onPress={Keyboard.dismiss}>
<View style={styles.appContainer}>
<View style={styles.matrixContainer}>
{ this._renderMatrixInputs() }
</View>
<View style={styles.solutionsContainer}>
{/* solutions here */}
</View>
</View>
</TouchableWithoutFeedback>
</View>
);
}
_renderMatrixInputs() {
// harcoded 3 x 3 matrix for now....
let views = [];
let {size} = this.state;
for (var r = 0; r < size; r++) {
let inputRow = [];
for (var c = 0; c < size; c++) {
inputRow.push(
<InputBox value={'X'} key={r.toString() +c.toString()} />
);
}
views.push(<View style={styles.inputRow} key={r.toString()}>{inputRow}</View>)
}
return views
}
}
const styles = StyleSheet.create({
rootContainer: {
flex:25,
backgroundColor: 'lightyellow',
},
appContainer: {
flex:1,
backgroundColor: 'lightblue'
},
matrixContainer: {
marginTop: 25,
flex: 3, // take up half of screen
backgroundColor: 'ivory',
},
solutionsContainer: {
flex:5, // take up other half of screen
backgroundColor: 'lavenderblush',
},
inputRow: {
flex: 1,
maxHeight: 75,
flexDirection: 'row',
justifyContent: 'center',
alignItems: 'center',
},
inputContainer: {
flex: 1,
margin: 3,
maxHeight: 35,
maxWidth: 75,
borderBottomWidth: 1,
borderBottomColor: 'gray',
},
matrixNumberInput: {
flex:1,
backgroundColor:"azure"
}
});
谢谢!
