我定义了两个TextInput字段如下:
<TextInput
style = {styles.titleInput}
returnKeyType = {"next"}
autoFocus = {true}
placeholder = "Title" />
<TextInput
style = {styles.descriptionInput}
multiline = {true}
maxLength = {200}
placeholder = "Description" />
但在按下键盘上的“next”按钮后,我的react-native应用程序并没有跳转到第二个TextInput字段。我怎样才能做到呢?
谢谢!
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"
/>
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
