我看不出爲什麼佔位符不會出現在<TextInput>
的兩個位置上。另外,當用戶鍵入內容時,在<TextInput>
框中沒有任何內容顯示。我想知道爲什麼會發生這種情況。爲什麼我的佔位符不會顯示在TextInput中
這裏是App.js
:
import React, {Component} from 'react';
import {View, StyleSheet} from 'react-native';
import BackGround from './components/BackGround';
export default class App extends Component {
render() {
return(
<View style={styles.back}>
<BackGround/>
</View>
);
}
}
const styles = StyleSheet.create({
back: {
flex: 1
}
});
這裏是Login.js
:
import React, {Component} from 'react';
import {StyleSheet, TextInput, View, Text, TouchableOpacity} from 'react-native';
class Login extends Component {
render() {
return(
<View>
<TextInput
placeholder={"Email"}
placeholderTextColor={"#E365F4"}
style={styles.input}
/>
<TextInput
placeholder={"Password"}
placeholderTextColor={"#f44242"}
style={styles.input}
/>
<TouchableOpacity>
<Text style={styles.loginAndCA}>Login</Text>
</TouchableOpacity>
<TouchableOpacity>
<Text style={styles.loginAndCA}>Create Account</Text>
</TouchableOpacity>
</View>
);
}
}
const styles = StyleSheet.create({
input: {
backgroundColor: 'green',
paddingBottom: 20,
padding: 20,
paddingHorizontal: 150,
marginBottom: 10
},
loginAndCA: {
fontSize: 40,
textAlign: 'center',
color: 'white',
fontFamily: 'Bodoni 72 Smallcaps'
}
});
export default Login;
這裏是BackGround.js
:這裏
import React, {Component} from 'react';
import {StyleSheet, Image, View} from 'react-native';
import Login from './Login';
export default class BackGround extends Component {
render() {
return(
<View style={styles.first}>
<Image style={styles.container} source={require('../pictures/smoke.jpg')}>
<View style={styles.second}>
<Login/>
</View>
</Image>
</View>
);
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
width: null,
height: null,
backgroundColor: 'rgba(0,0,0,0)',
resizeMode: 'cover'
// resizeMode: 'contain' // Shows image completely.
},
first: {
flex: 1
},
second: {
paddingTop: 290 // Moves both <TextInput> boxes down.
}
});`
