Voici la copie de mon fichier xml content_main activity sur Layout.Ligne d'erreur: Provoquée par: android.view.InflateException: ligne de fichier XML binaire # 19: ligne de fichier XML binaire # 10: erreur de classe

Aucune idée, comment résoudre ce code. Je pense que cela a quelque chose à voir avec mon fichier de mise en page.

<com.example.chadymaebarinan.drawingview 
    android:id="@+id/drawing" 
    android:layout_width="fill_parent" 
    android:layout_height="0dp" 
    android:layout_marginBottom="3dp" 
    android:layout_marginLeft="5dp" 
    android:layout_marginRight="5dp" 
    android:layout_marginTop="3dp" 
    android:layout_weight="1" 
    android:background="#FFFFFFFF" />

Mais je ne sais pas :(S'il vous plaît me dire comment corriger les erreurs Merci beaucoup

Mise à jour:.! Voici ma classe drawingview

package com.example.chadymaebarinan .drawingview;

    paintColor = Color.parseColor(newColor); 
    drawPaint.setColor(paintColor); 
//set color 
} 
}

Code postal de votre classe: 'com.example.chadymaebarinan.drawingview' –

Si vous travaillez le long de la trace de la pile, vous verrez:' AndroidRuntime: Causée par: java.lang.ClassNotFoundException: Didn » t find class "com.example.chadymaebarinan.drawingview" sur le chemin: DexPathList [[fichier zip "/data/app/com.example.chadymaebarinan.drawingview- 'etc .. Ceci est le problème de base –

@dieter_h Juste terminé la mise à jour. :) – ChuddyWagogo

Il vous manque le nom de classe sur votre XML

Votre nom du package est com.example.chadymaebarinan.drawingview ... Donc, vous obtenez un ClassNotFoundException.

Modifiez votre fichier XML pour utiliser le nom complet de la classe DrawingView.

<com.example.chadymaebarinan.drawingview.DrawingView 
    android:id="@+id/drawing" 
    android:layout_width="fill_parent"

Omg Merci beaucoup L'application a finalement travaillé. toi!!!! – ChuddyWagogo

Essayez de mettre en œuvre 3 constructeurs de votre classe pas un seul

Si pas d'aide, essayez de déboguer le code de classe DrawingView.

Comment est-ce que cela répond à la question? Vous venez de copier le constructeur qui a déjà été défini –

Ajout de constructeurs ne résout pas l'exception, bien que –

Ligne d'erreur: Provoquée par: android.view.InflateException: ligne de fichier XML binaire # 19: ligne de fichier XML binaire # 10: erreur de classe
