Answer 1

你可以使用onFocus并onBlur完成这项工作

state: {
    isFocused: true
}

 handleFocus = () => this.setState({isFocused: true})

 handleBlur = () => this.setState({isFocused: false})

 <TextInput
         onFocus={this.handleFocus}
         onBlur={this.handleBlur}
         style={[//Your Styles, {
             borderBottomColor: this.state.isFocused
                 ? 'black'
                 : 'red',
             borderBottomWidth: 1,
         }]}
     />
