Erreur View personnalisée génère InflateException

**Drowan** · 08/04/2016, 13h51

J'essaye de créer une view perso, mais lors du chargement j'ai le droit a un bel android.view.InflateException.

Ma view perso :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.view.View;
 
public class ViewfinderView extends View {
	Paint paint = new Paint();
 
	public ViewfinderView(Context context) {
		super(context);
	}
 
	@Override
	protected void onDraw(Canvas canvas) {
		paint.setColor(Color.RED);
		paint.setStrokeWidth(1);
		paint.setStyle(Paint.Style.STROKE);
		canvas.drawRect(30, 80, 30, 80, paint);
	}
}

Quelqu'un en a une ?
