Error inflating when extending a class


I think I figured out why this wasn't working. I was only providing a constructor for the case of one parameter 'context' when I should have provided a constructor for the two parameter 'Context, AttributeSet' case. I also needed to give the constructor(s) public access. Here's my fix:

public class GhostSurfaceCameraView extends SurfaceView implements SurfaceHolder.Callback {        SurfaceHolder mHolder;        Camera mCamera;        public GhostSurfaceCameraView(Context context)        {            super(context);            init();        }        public GhostSurfaceCameraView(Context context, AttributeSet attrs)        {            super(context, attrs);            init();        }        public GhostSurfaceCameraView(Context context, AttributeSet attrs, int defStyle) {            super(context, attrs, defStyle);            init();        }


@Tim - Both the constructors are not required, only the ViewClassName(Context context, AttributeSet attrs ) constructor is necessary. I found this out the painful way, after hours and hours of wasted time.

I am very new to Android development, but I am making a wild guess here, that it maybe due to the fact that since we are adding the custom View class in the XML file, we are setting several attributes to it in the XML, which needs to be processed at the time of instantiation. Someone far more knowledgeable than me will be able to shed clearer light on this matter though.


Another possible cause of the "Error inflating class" message could be misspelling the full package name where it's specified in XML:

<com.alpenglow.androcap.GhostSurfaceCameraView android:id="@+id/ghostview_cameraview"    android:layout_width="fill_parent"    android:layout_height="fill_parent"/>

Opening your layout XML file in the Eclipse XML editor should highlight this problem.
