Had the same issue, so I just implemented all the three constructors in the Java class of my custom view all the three constructors plus onDrow method and it worked like a charm. Try it.

import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.Path;
import android.util.AttributeSet;
import android.view.View;

public class CustomWorldWideView extends View {

    public CustomWorldWideView(Context context) {

        super(context);
    }

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

    public CustomWorldWideView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    protected void onDraw(Canvas canvas) {
        super.onDraw(canvas);

        //Some simple draw on the view...
        Paint paint = new Paint();
        paint.setStyle(Paint.Style.FILL);
        paint.setColor(Color.parseColor("#FFA800"));


        Path path = new Path();

        path.moveTo(0, 0);
        path.lineTo(getWidth() / 2, 0);
        path.lineTo(getWidth(), getHeight()/2);
        path.lineTo(getWidth() / 2, getHeight());
        path.lineTo( 0, getHeight());
        path.lineTo( 0, 0);

        canvas.drawPath(path, paint);


    }
}

The XML :
