Android - Est-il possible d'avoir 2 RecyclerViews dans 1 activité + XML?

Question

Existe-t-il un moyen d'avoir 2 vues recycleur dans 1 XML + Activité? Je rencontre des problèmes lorsque j'implémente ListItemClickListener de mon adaptateur car il dit que 'Class HomeActivity doit être déclaré abstrait ou implémenter une méthode abstraite' onListItemClick (MyIssueDao) 'dans' ListItemClickListener '.

Est-il possible de partager la méthode 'onListItemClick' avec mes 2 vues recycleur ???

Answer 1

vous mis en œuvre une seule de vos deux interfaces dans HomeActivity.java: on est onListItemClick(IssueDao) dans votre IssueDao.java, et l'autre est onListItemClick(MyIssueDao) dans MyIssueDao.java. Ici vous avez implémenté onListItemClick(IssueDao) uniquement. Implémentez l'autre et ça devrait marcher.

Answer 2

Voici la réponse:

Vous devez mettre dans votre .xml la LinearLayout dans un ScrollView et utiliser wrap_content comme RecyclerView'slayout_height.

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="fill_parent" 
android:layout_height="wrap_content" 
android:fillViewport="true"> 

<LinearLayout 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:orientation="vertical" > 

    <TextView 
     android:layout_width="match_parent" 
     android:layout_height="@dimen/list_header" 
     android:background="@color/header" 
     android:gravity="center" 
     android:text="@string/find_friends__already_playing" 
     android:visibility="visible" /> 

    <android.support.v7.widget.RecyclerView 
     android:id="@+id/in_app_friends" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:layout_marginBottom="5dp" 
     android:background="@color/white"/> 

    <TextView 
     android:layout_width="match_parent" 
     android:layout_height="@dimen/list_header" 
     android:background="@color/find_friends__header" 
     android:gravity="center" 
     android:text="@string/find_friends__invite_friends" /> 

    <android.support.v7.widget.RecyclerView 
     android:id="@+id/friends_to_invite" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:background="@color/white"/> 
</LinearLayout> 
</ScrollView> 

Aussi il y a un bug avec des RecyclerView et wrap_content donc vous devez utiliser un gestionnaire de mise en page personnalisée. Vérifiez ce message: [Comment puis-je faire le travail de WRAP_CONTENT sur un RecyclerView] [1]

Dans votre code java, définissez deuxième onListItemClick(IssueDao) Il fonctionne sur moi !!!
