Use Custom View In XML Layout
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?

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

How can I pass the parameters

<view class="Your_package.MainClass$Loading" />

<Your-Package-Name.Loading
      android:layout_width="fill_parent"
      android:layout_height="fill_parent"
     />

<com.your.package.Loading
    android:id="@+id/y_view1"
    ... />

Loading yourView = (Loading) findViewById(R.id.yourLoadingView);
yourView.setInputStream();

public void setInputStream(InputStream inputStream){
    movie = Movie.decodeStream(inputStream);
}
