焦点功能正常。
<View style={{flexDirection: 'row'}}>
<Text style={{flex: 1}}>Enter Name: </Text>
<TextInput ref="name" onChangeText={(name) => this.setState({name})} style={{flex: 1}}
onSubmitEditing={() => this.refs.age.focus()}/>
</View>
<View style={{flexDirection: 'row'}}>
<Text style={{flex: 1}}>Enter Age: </Text>
<TextInput ref="age" keyboardType="numeric" onChangeText={(age) => this.setState({age})} style={{flex: 1}}
onSubmitEditing={() => this.refs.sport.focus()}/>
</View>
<View style={{flexDirection: 'row'}}>
<Text style={{flex: 1}}>Enter Favourite Sport: </Text>
<TextInput ref="sport" onChangeText={(sport) => this.setState({sport})} style={{flex: 1}}/>
</View>
希望这会有所帮助。这是为了安卓。

您必须在您想要关注的输入上使用用户参考:
<Input
ref={(node) => { this.myInput = node }}
value={this.state.myInput.toString()}
onSubmitEditing={() => { this.myOtherInput.focus() }}/>
<Input
ref={(node) => { this.myOtherInput = node }}
value={this.state.myOtherInput.toString()}/>
您可以看到,当您在第一个输入上提交编辑时,您将专注于第二个输入。你可以在任何地方使用this.MY_CUSTOM_REF.focus()。

为我工作:
<Input
blurOnSubmit={false}
returnKeyType="next"
onSubmitEditing={() => {
this.passwordInput.wrappedInstance.focus();
}}
/>
<Input
secureTextEntry
ref={(input) => {
this.passwordInput = input;
}}
/>

我在自定义组件中插入了该函数。
public focus(){
this.input.focus()
}

看看这篇文章,这可能很方便react-native inputs
//Helper function
focusNextField(nextField) {
this.refs[nextField].focus();
}
<TextInput
ref='1'
style={styles.otpInputStyle}
keyboardType='numeric'
secureTextEntry
value={this.props.otp1}
maxLength={1}
onChangeText={(num) => {
this.props.otpCode1(num); //action call
if (num && num.length === 1) {
this.focusNextField('2'); //function call. '2' ref to next input ref
}
}}
/>

import React, { useRef } from 'react';
...
export default function YourFuctionalComponent() {
const input1 = useRef(null);
const imput2 = useRef(null);
const doSomething = () => {}
return(
<>
<TextInput
autoFocus
ref={input1}
onSubmitEditing={() => { imput2.current.focus(); }}
returnKeyType="next"
/>
<TextInput
ref={input2}
onSubmitEditing={() => doSomething()}
returnKeyType="done"
/>
</>
);
}
