Buttermesser Ansicht Halter Muster in benutzerdefinierten Adapter

Question

Ich versuche, Buttermesser in einem benutzerdefinierten Adapter wie die Dokumentation zu nutzen werben: http://jakewharton.github.io/butterknife/ Ich klebte den Beispielcode und eingefügt, um das Layout mit meiner RelativeLayout Datei:

@Override public View getView(int position, View view, ViewGroup parent) { 
    ViewHolder holder; 
    ButterKnife.setDebug(true); 
    if (view != null) { 
     holder = (ViewHolder) view.getTag(); 
    } else { 
     view = inflater.inflate(R.layout.list_row_people, parent, false); 
     holder = new ViewHolder(view); 
     view.setTag(holder); 
    } 

    holder.name.setText("John Doe"); 
    // etc... 

    return view; 
    } 

Diese

ist der Code des ViewHolder (Inline-Klasse von PeopleAdapter):

static class ViewHolder { 
    @BindView(R.id.name) 
    TextView name; 

    public ViewHolder(View view) { 
     ButterKnife.bind(this, view); 
    } 
} 

Leider holder.name.setText("John Doe"); wirft eine Nullpointer-Ausnahmen wie name n ull. Die Debug-Ausgabe dieser Zeilen zeigt:

13:11:32.816 11613-11613/com.myproject.debug D/ButterKnife: Looking up view binder for com.myproject.controller.adapters.PeopleAdapter$ViewHolder 
13:11:32.827 11613-11613/com.myproject.debug D/ButterKnife: Not found. Trying superclass java.lang.Object 
13:11:32.827 11613-11613/com.myproject.debug D/ButterKnife: MISS: Reached framework class. Abandoning search. 

list_row_people.xml sieht derzeit wie folgt aus:

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:orientation="vertical"> 

    <TextView 
     android:id="@+id/name" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_alignParentTop="true" 
     android:gravity="center_vertical" 
     android:padding="4dp" 
     android:text="@string/example_name" 
     android:textAppearance="?android:attr/textAppearanceLarge" /> 
</RelativeLayout> 

https://github.com/JakeWharton/butterknife/issues/285 Lesen, fügte ich die folgende Zeile in meinem proguard-rules.pro:

-keep class **$$ViewBinder { *; }
