如果你的TextInput在另一个组件中，要让这个被接受的解决方案工作，你需要从ref“弹出”到父容器的引用。

// MyComponent
render() {
    <View>
        <TextInput ref={(r) => this.props.onRef(r)} { ...this.props }/>
    </View>
}

// MyView
render() {
    <MyComponent onSubmitEditing={(evt) => this.myField2.focus()}/>
    <MyComponent onRef={(r) => this.myField2 = r}/>
}

我的场景是< CustomBoladonesTextInput />包装一个RN < TextInput />。

我是这样解决这个问题的:

我的表单是这样的:

  <CustomBoladonesTextInput 
      onSubmitEditing={() => this.customInput2.refs.innerTextInput2.focus()}
      returnKeyType="next"
      ... />

  <CustomBoladonesTextInput 
       ref={ref => this.customInput2 = ref}
       refInner="innerTextInput2"
       ... />

在CustomBoladonesTextInput的组件定义中，我像这样将refField传递给内部的ref道具:

   export default class CustomBoladonesTextInput extends React.Component {
      render() {        
         return (< TextInput ref={this.props.refInner} ... />);     
      } 
   }

瞧。一切恢复正常。 希望这能有所帮助

在你的组件中:

constructor(props) {
        super(props);
        this.focusNextField = this
            .focusNextField
            .bind(this);
        // to store our input refs
        this.inputs = {};
    }
    focusNextField(id) {
        console.log("focus next input: " + id);
        this
            .inputs[id]
            ._root
            .focus();
    }

注意:我使用了._root，因为它是NativeBase' library ' Input中的TextInput的引用

在文本输入中，像这样

<TextInput
         onSubmitEditing={() => {
                          this.focusNextField('two');
                          }}
         returnKeyType="next"
         blurOnSubmit={false}/>


<TextInput      
         ref={input => {
              this.inputs['two'] = input;
                        }}/>

如果你正在使用NativeBase作为UI组件，你可以使用这个示例

<Item floatingLabel>
    <Label>Title</Label>
    <Input
        returnKeyType = {"next"}
        autoFocus = {true}
        onSubmitEditing={(event) => {
            this._inputDesc._root.focus(); 
        }} />
</Item>
<Item floatingLabel>
    <Label>Description</Label>
    <Input
        getRef={(c) => this._inputDesc = c}
        multiline={true} style={{height: 100}} />
        onSubmitEditing={(event) => { this._inputLink._root.focus(); }} />
</Item>

你不需要裁判也可以做到。这种方法是首选的，因为引用会导致脆弱的代码。React文档建议在可能的情况下寻找其他解决方案:

If you have not programmed several apps with React, your first inclination is usually going to be to try to use refs to "make things happen" in your app. If this is the case, take a moment and think more critically about where state should be owned in the component hierarchy. Often, it becomes clear that the proper place to "own" that state is at a higher level in the hierarchy. Placing the state there often eliminates any desire to use refs to "make things happen" – instead, the data flow will usually accomplish your goal.

相反，我们将使用一个状态变量来聚焦第二个输入字段。

Add a state variable that we'll pass as a prop to the DescriptionInput: initialState() { return { focusDescriptionInput: false, }; } Define a handler method that will set this state variable to true: handleTitleInputSubmit() { this.setState(focusDescriptionInput: true); } Upon submitting / hitting enter / next on the TitleInput, we'll call handleTitleInputSubmit. This will set focusDescriptionInput to true. <TextInput style = {styles.titleInput} returnKeyType = {"next"} autoFocus = {true} placeholder = "Title" onSubmitEditing={this.handleTitleInputSubmit} /> DescriptionInput's focus prop is set to our focusDescriptionInput state variable. So, when focusDescriptionInput changes (in step 3), DescriptionInput will re-render with focus={true}. <TextInput style = {styles.descriptionInput} multiline = {true} maxLength = {200} placeholder = "Description" focus={this.state.focusDescriptionInput} />

这是避免使用refs的好方法，因为refs会导致更脆弱的代码:)

编辑:h/t @LaneRettig指出，你需要用一些添加的道具和方法来包装React Native TextInput，以获得对焦点的响应:

    // Props:
    static propTypes = { 
        focus: PropTypes.bool,
    } 

    static defaultProps = { 
        focus: false,
    } 

    // Methods:
    focus() {
        this._component.focus(); 
    } 

    componentWillReceiveProps(nextProps) {
        const {focus} = nextProps; 

        focus && this.focus(); 
    }

设置第二个TextInput焦点，当前一个TextInput的onSubmitEditing被触发时。

试试这个

为第二个TextInput添加一个引用 Ref ={(input) => {this。secondTextInput =输入;}} 绑定焦点函数到第一个TextInput的onSubmitEditing事件。 onSubmitEditing={() => {this.secondTextInput.focus();}} 记住将blurOnSubmit设置为false，以防止键盘闪烁。 blurOnSubmit ={假}

当一切都完成后，它应该看起来像这样。

<TextInput
    placeholder="FirstTextInput"
    returnKeyType="next"
    onSubmitEditing={() => { this.secondTextInput.focus(); }}
    blurOnSubmit={false}
/>

<TextInput
    ref={(input) => { this.secondTextInput = input; }}
    placeholder="secondTextInput"
/>
