我有一个注册表单,我想在用户将其聚焦并弹出键盘时清除文本输入。
此行为在iOS上工作正常,但是在android上,首先是clearTextOnFocus无法正常工作,其次我无法在地址文本输入中输入任何内容,我想知道这里出了什么问题,因为这在iOS上非常完美
export default class SignupScreen extends Component {
static navigationOptions = {
title: strings.signup,
headerTintColor:'black'
};
constructor(props) {
super(props);
this.state = { loading:true,loginText:strings.username,pwdText:strings.password,nameText:strings.name,phoneNoText:strings.phone,addressText:strings.address,lineIdText:strings.line,loading:false };
}
render() {
const { navigate } = this.props.navigation;
return (
<ImageBackground
source={require('./images/marble.jpg')}
style={styles.backgroundImage}>
<KeyboardAwareScrollView>
<View style={styles.container}>
<Spinner visible={this.state.loading} textContent={"Loading..."} textStyle={{color: '#FFF'}} />
<Image style = {styles.logoFit} resizeMode="contain" source={require('./images/Logo1.png')}/>
<View>
<TextInput clearTextOnFocus={true} style={styles.textInput} value={this.state.loginText }
onChangeText={(textInputValue1) => this.setState({loginText:textInputValue1})} keyboardType='email-address' ></TextInput>
<TextInput clearTextOnFocus={true} style={styles.textInput} value={this.state.pwdText}
onChangeText={(textInputValue2) => this.setState({pwdText:textInputValue2})}></TextInput>
<TextInput clearTextOnFocus={true} style={styles.textInput} value={this.state.phoneNoText}
onChangeText={(textInputValue) => this.setState({phoneNoText:textInputValue})}></TextInput>
<TextInput clearTextOnFocus={true} style={styles.textInput} value={this.state.nameText}
onChangeText={(textInputValue) => this.setState({nameText:textInputValue})}></TextInput>
<TextInput clearTextOnFocus={true} style={styles.textInput} value={this.state.addressText}
onChangeText={(textInputValue) => this.setState({adressText:textInputValue})}></TextInput>
<TextInput clearTextOnFocus={true} style={styles.textInput} value={this.state.lineIdText}
onChangeText={(textInputValue) => this.setState({lineIdText:textInputValue})}></TextInput>
</View>
<View style={styles.buttonSection}>
<TouchableOpacity onPress = {this.onSignup}>
<View style = { styles.donebutton}>
<Text style = {{color: 'white'}}>{strings.signup}</Text>
</View>
</TouchableOpacity>
</View>
</View>
</KeyboardAwareScrollView>
</ImageBackground>
);
}
}
任何朝着这个方向的帮助都会很棒。

问题可能是您设置了value
的{{1}}属性。如果设置了TextInput
,它将覆盖您尝试在其中编写的所有内容。您应该改用value
属性。
