Question

I have a custom view:

public class Loading extends View {

    private long movieStart;
    private Movie movie;

    public Loading(Context context, InputStream inputStream) {
        super(context);
        movie = Movie.decodeStream(inputStream);
    }

    @Override
    protected void onDraw(Canvas canvas) {
        canvas.drawColor(Color.WHITE);
        super.onDraw(canvas);
        final long now = SystemClock.uptimeMillis();
        if(movieStart == 0)
            movieStart = now;
        final int relTime = (int)((now - movieStart) % movie.duration());
        movie.setTime(relTime);
        movie.draw(canvas, 0, 0);
        this.invalidate();
    }

}

How can I use this view in XML layout? How can I pass the parameters (Context, InputStream) in XML layout?

How can I use this view in XML layout?

..

 <pacakge_of_class.Loading 
            android:id="@+id/y_view1"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent" />

http://developer.android.com/guide/topics/ui/custom-components.html

There is a form of the constructor that are called when the view is created from code and a form that is called when the view is inflated from a layout file. The second form should parse and apply any attributes defined in the layout file.

How can I pass the parameters
