plante App lorsque vous essayez d'ajouter une nouvelle CyborgController en utilisant createNewLayerBuilder()

Question

C'est ce que je fais dans la classe d'application:

@Override 
public void onCreate() { 
    super.onCreate(); 
    CyborgBuilder.startCyborg(new CyborgConfiguration(this, R.layout.cyborgview__auto_reply, BasicModulePack.class)); 
} 

Voici comment cyborgview__auto_reply.xml ressemble:

<?xml version="1.0" encoding="utf-8"?> 
<com.nu.art.cyborg.core.CyborgView 
xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:cyborg="http://schemas.android.com/apk/res-auto" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
cyborg:controller="com.hedshafran.autoreply.controllers.Controller_PermissionScreen" 
cyborg:tag="Controller_Permission"/> 

Et voici ce que je fais dans la classe Controller_PermissionScreen qui provoque l'accident:

createNewLayerBuilder().setControllerType(Controller_MainScreen.class).setLayoutId(R.layout.controller__main_screen).build(); 

Cela provoque l'accident, qui ressemble à ceci:

Comment puis-je éviter cet accident et ouvrir une nouvelle CyborgController la bonne façon?

Answer 1

Votre cyborgview__auto_reply.xml devrait utiliser le CyborgStackConroller qui contiendra votre Controller_PermissionScreen, comme ceci:

<?xml version="1.0" encoding="utf-8"?> 
<com.nu.art.cyborg.core.CyborgView 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:cyborg="http://schemas.android.com/apk/res-auto" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:id="@+id/CV_RootStack" 
    cyborg:controller="com.nu.art.cyborg.core.CyborgStackController" 
    cyborg:rootController="com.hedshafran.autoreply.controllers.Controller_PermissionScreen" 

    cyborg:rootTag="Controller_Permission" 
    cyborg:tag="RootStack" 
    /> 

Point est que vous ne pouvez utiliser le createNewLayerBuilder api si le contrôleur qui appelle cette méthode est une pile. Sinon, utilisez le getControllerById (R.id.CV_RootStack) et créez un nouveau générateur de calques.
