android.view.InflateException: fichier XML binaire

Question

Je reçois cette erreur étrange dans le logcat et j'ai essayé tout ce qui me vient à l'esprit pour le résoudre et l'obtenir toujours. Voici le logcat:

et ceci est mon xml:

<?xml version="1.0" encoding="utf-8"?> 
<merge xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:bitdraw="http://schemas.android.com/apk/res/com.dm.test" > 

    <view 
    class="com.dm.test.ui.BitCanvasActivity$CanvasView" 
    android:id="@+id/backgroundz" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    /> 

    <com.dm.test.widget.ActionButtons 
     android:id="@+id/btn_actions" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_weight="1" 
     android:layout_marginBottom="135dp" 
     android:layout_gravity="bottom|center_horizontal" /> 


    <com.dm.test.widget.ColorPicker 
     android:id="@+id/color_picker" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_gravity="bottom|center_horizontal" 
     android:orientation="horizontal" 
     bitdraw:colors="@array/color_picker_colors" 
     bitdraw:cols="3" 
     bitdraw:fils="5" /> 

</merge> 

et sur la ligne .java 55 son présent:

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.bit_canvas); //line 55 
    mActionButtons = (ActionButtons) findViewById(R.id.btn_actions); 
    mColorPicker = (ColorPicker) findViewById(R.id.color_picker); 

et cela fait partie de l'intérieur classe:

public class CanvasView extends View { 

    public CanvasView(Context c) { 
     super(c); 
    } 

    public CanvasView(Context context, AttributeSet attrs) { 
     super(context, attrs); 
    } 

    public CanvasView (Context c, AttributeSet atr, int defstyle){ 
     super(c, atr,defstyle); 
    } 

    @Override 
    protected void onDraw(Canvas canvas) { ... } 

Any l'aide serait très appréciée, parce que j'ai sérieusement manqué d'idées: S

Essayez de modifier votre mise en page pour celle ci-dessous, puisque sur ce chemin, vous appellerez l'élément de classe.

<?xml version="1.0" encoding="utf-8"?> 
<merge xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:bitdraw="http://schemas.android.com/apk/res/com.dm.test" > 

    <com.dm.test.ui.BitCanvasActivity.CanvasView 
    android:id="@+id/backgroundz" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    /> 

    <com.dm.test.widget.ActionButtons 
     android:id="@+id/btn_actions" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_weight="1" 
     android:layout_marginBottom="135dp" 
     android:layout_gravity="bottom|center_horizontal" /> 


    <com.dm.test.widget.ColorPicker 
     android:id="@+id/color_picker" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_gravity="bottom|center_horizontal" 
     android:orientation="horizontal" 
     bitdraw:colors="@array/color_picker_colors" 
     bitdraw:cols="3" 
     bitdraw:fils="5" /> 

</merge> 

Si cela ne fonctionne pas essayez de faire votre classe comme dit jordi.

Vous avez besoin d'un "gestionnaire" pour modifier l'interface Android dans un thread.
