ViewHolder mit einem Konstruktor, der eine Ansicht Recycler View

Question

Hallo Freunde ich hatte in diesem Problem von 2 Tagen Ich weiß nicht, was das Problem hier bin ich bin mit der Fast Adapter von mikepenz, wo ich zwei Recycler sehen in diesem. Hier ich diesen Fehler

java.lang.RuntimeException: You have to provide a ViewHolder with a constructor which takes a view! 
at com.mikepenz.fastadapter.items.AbstractItem$ReflectionBasedViewHolderFactory.create(AbstractItem.java:349) 

bin immer ich denke, ich das alles gesetzt hatte richtig, wie ich auch in anderen Klasse gleiche Format verwende, aber ich bin nur dieses Problem Klasse gegenüber nur und ich nicht die progurard aktiviert haben melden Sie sich bitte die folgenden Code

Hauptklasse:

Answer 1

Soweit ich sagen kann, dass Sie eine veraltete Version des FastAdapter verwenden, die noch eine Funktion aktiviert hatte, um automatisch die zur Verfügung gestellt ViewHolder zu erkennen. Da diese Funktionalität manchmal zu der obigen Fehlermeldung führt (wenn sie mit proguard verwendet wird), wurde sie in einer neueren Version entfernt und durch eine einfache getViewHolder Methode ersetzt. https://github.com/mikepenz/FastAdapter/blob/develop/MIGRATION.md#v250

Für ältere Versionen des FastAdapter, war es das Konzept eines ViewHolderFactory das würde (als Alternative zur automatischen Erkennung, die:

@Override 
public ViewHolder getViewHolder(View v) { 
    return new ViewHolder(v); 
} 

Dieser neue Ansatz mit dem FastAdapter v2.5.0 eingeführt wurde in Ihrem Fall funktioniert nicht) bieten die ViewHolder die zu FastAdapter

Grundsätzlich würden Sie die ViewHolderFactory implementieren und die ViewHolderFactory in Ihrem Element zu definieren.

private static final ViewHolderFactory<? extends ViewHolder> FACTORY = new ItemFactory(); 

Zusätzlich würden Sie folgende Voraussetzungen:

/** 
* our ItemFactory implementation which creates the ViewHolder for our adapter. 
* It is highly recommended to implement a ViewHolderFactory as it is 0-1ms faster for ViewHolder creation, 
* and it is also many many times more efficient if you define custom listeners on views within your item. 
*/ 
protected static class ItemFactory implements ViewHolderFactory<ViewHolder> { 
    public ViewHolder create(View v) { 
     return new ViewHolder(v); 
    } 
} 

/** 
* return our ViewHolderFactory implementation here 
* 
* @return 
*/ 
@Override 
public ViewHolderFactory<? extends ViewHolder> getFactory() { 
    return FACTORY; 
} 

Sie die ganze Sache hier sehen können: https://github.com/mikepenz/FastAdapter/blob/v2.2.0/app/src/main/java/com/mikepenz/fastadapter/app/items/IconItem.java#L24

Als Alternative die proguard Regeln Anpassung könnte auch funktionieren.

Meine Empfehlung ist, auf eine der neuesten FastAdapter Releases zu aktualisieren, da dies stark vereinfacht und verbessert wurde.
