How to change the state in conditional - React

Question

I need to change the state of sibling components in my React App. I use state and setstate

I need to change the state of sibling components. When loading the page, there must exist (visible in the page) <BkUser /> and when clicking "button id =" ds-visual "it must be deleted (<BkUser /> mustn't exist) and there must exist <BkDescanso />. When you click on <BkSleep /> (in the div parent) you should remove <BkDescanso /> and show <BkUser />

This is the web. There should never be <BkUser/> and <BkSleep> at the same time. <Bkuser /> is the blue block and <BkDescanso /> is the red block

This is my code:

Edit: I edit my original code because I fix the problem. This is the final OK Code. In the end the most important thing was the state conditional

{
this.state.usuario ? (<BkUser handleClick = {this.handleClick} usuario={this.state.usuario}/>): (<BkDescanso handleClick = {this.handleClick} usuario={this.state.usuario}/>)}

import React, { Component } from 'react';

class Header extends Component {
    constructor(props) {
        super(props);

        this.state = {
            usuario: true,
        };

        this.handleClick = this.handleClick.bind(this);
    }

    handleClick() {
        this.setState(state => ({
          usuario: !state.usuario
        }));
        //alert("Works button");
      }

    render(){
        return (
            <header className="header">
                <div className="configuracion">
                {
          this.state.usuario
            ? (
                <BkUser handleClick = {this.handleClick} usuario={this.state.usuario}/>
            )
            : (
                <BkDescanso handleClick = {this.handleClick} usuario={this.state.usuario}/>
                )}
                    <div className="content-btn">
                        <button id="config" className='btn btn--rounded'><span className="ico-configuracion"></span></button>
                        <button id="salir" className='btn btn--rounded'><span className="ico-exit"></span></button>
                    </div>
                </div>
            </header>
        );
    }
}

class BkUser extends Component{

    render(){
            return ((    
                <div className='usuario'>
                    <img src="../img//usuario.svg" alt="Imagen usuario"/>
                    <div className="content-usuario">
                        <span id="nm-usuario" className="h4">Hermione Jane Granger</span>
                        <span id="tp-usuario" className="h5">Supervisor</span>
                    </div>
                    <div className="content-descansos">
                        <div className="botones">
                            <button id="ds-visual" className='btn btn--rounded' onClick={this.props.handleClick}><span className="ico-visual"></span></button>
                            <button id="ds-admin" className='btn btn--rounded'><span className="ico-tiempo-administrativo"></span></button>
                            <button id="ds-otros" className='btn btn--rounded'><span className="ico-descanso"></span></button>
                        </div>
                        <div className="ds-actual">
                            <span id="ds-tipo">Administrativo</span>
                            <span id="ds-tiempo">00:08:47</span>
                        </div>
                    </div>
                </div>
            ));
    }
}

class BkDescanso extends Component {

    render(){
        return ((   
            <div className='usuario descanso' onClick={this.props.handleClick}>
                <h3>Finalizar descanso</h3>
            </div>
        ));
    }
}


export default Header;

Right now handleClick works but always exist BkUser and BkDescanso. I need only one to exist. If you click on id = "ds-visual" the bkUser block should disappear and BkDescanso appear. Then if you click on div className = 'user rest' in BkUser there should only be BkDescanso.

I think that it is not able to know when it is true and when it is false to show or hide

Thanks a lot for the help.

You're missing two things:

First you have to pass the handleClick function to the BkUser component, and then you have to call it via this.props.handleClick.

...
<BkUser handleClick={this.handleClick} usuario={this.state.usuario} />
....
<button
    id="ds-visual"
    className="btn btn--rounded"
    onClick={this.props.handleClick}
    >
    ds-visual
    <span className="ico-visual" />
</button>
