javascript - Comment changer de vues sur le même écran (React Native) ?

Je veux dupliquer ce qui suit avec react-native-scrollable-tab-view :

Actuellement, mon code est le suivant, mais je ne sais pas comment exécuter et incorporer le module pour faciliter les choses - quelqu'un a-t-il des idées sur la façon dont je peux mettre cela en œuvre ? (Je suis novice donc toute aide est appréciée) :

Ceci est l'onglet principal (vue par onglets) :

Actuellement, tout cela ressemble à ceci :

Ce que je ferais, c'est créer un tableau d'objets avec chaque objet représentant les différentes vues/composants dans votre curseur de pied de page. Ensuite, avoir une propriété dans votre état qui est l'onglet actif et quand un utilisateur clique sur un nouvel onglet, mettre à jour l'onglet actif avec l'index correspondant au nouvel onglet. Ce que nous allons faire, c'est, quel que soit l'onglet actif, prendre ce composant spécifique que vous avez dans le tabMap que vous avez créé ci-dessus et le rendre. Le code ressemblera à quelque chose comme ça.

var tabMap = [
  {key: 0, icon: 'ion|ios-contact-outline', state: 'bio', asArray: false, Component: About},
  {key: 1, icon: 'ion|ios-paper', state: 'posts', asArray: true, Component: Posts},
  {key: 2, icon: 'ion|ios-people', state: 'friends', asArray: false, Component: Friends},
  {key: 3, icon: 'ion|ios-heart', state: 'activity', asArray: false, Component: Activity},
];

Donc cela représente différentes onglets dans la section inférieure.

getInitialState(){
   return {
      activeTab: 0
   }
}

C'est mon état initial qui va garder la trace de l'onglet sur lequel je me trouve.

Puis dans ma méthode de rendu, je récupère le composant de l’onglet actif actuel,

var BodyComponent = tabMap[this.state.activeTabIndex].Component;

Maintenant que j'ai le composant, je peux simplement rendre BodyComponent en passant les données que je souhaite.

 <BodyComponent
    header={tabMap[this.state.activeTabIndex].header}
    authedUser={this.props.authedUser}
    isGuest={this.props.isGuest}
    userToRender={this.state.userToRender}
    data={this.state[tabMap[this.state.activeTabIndex].state]} />

C'était une fonctionnalité manquante de react-native-router-flux (pour passer d'un 'onglet' à l'autre dans un même conteneur) et je l'ai ajoutée récemment, veuillez vérifier la dernière version.

Vous devez utiliser l'élément Container et définir vos routes à l'intérieur. Vous devez également définir l'implémentation de TabBar à utiliser avec ce conteneur (consultez l'exemple avec son TabBarFlux)
