O que estou tentando alcançar:

medir um recipienteView no meu layout, mainContainer, definido noXMLpasse omainContainer's width and height para um costume diferenteView antesonDraw() é chamadoQuero passar a largura e a altura para que o costumeView sabe para onde desenharcanvas.drawBitmap usando coordenadasA visualização personalizada seráprogrammatically criado a partir do código

Como posso passar a largura int e a altura int medidas para o meu View personalizado antes que onDraw () seja chamado?

Visualização personalizada

public class AvatarView extends ImageView {

private Bitmap body;
private Bitmap hat;

public AvatarView(Context context) {
    super(context);
    init();
}

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

public AvatarView(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
    init();
}

private void init() {
    body = BitmapFactory.decodeResource(getResources(), R.drawable.battle_run_char);
    hat = BitmapFactory.decodeResource(getResources(), R.drawable.red_cartoon_hat);
}

@Override
protected void onDraw(Canvas canvas) {
    super.onDraw(canvas);
    canvas.drawBitmap(body, x, y, null);
    canvas.drawBitmap(hat, x, y, null);
}
}

Fragmento

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_customize_avatar, container, false);
    final RelativeLayout mainContainer = (RelativeLayout) view.findViewById(R.id.main_container);
    TwoWayView inventoryList = (TwoWayView) view.findViewById(R.id.inventory);

    inventoryList.setAdapter(null);

    inventoryList.setOnItemClickListener(new OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {

        }
    });

    mainContainer.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
        @SuppressLint("NewApi")
        @SuppressWarnings("deprecation")
        @Override
        public void onGlobalLayout() {
            // Retrieve the width and height
            containerWidth = mainContainer.getWidth();
            containerHeight = mainContainer.getHeight();

            // Remove global listener
            if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.JELLY_BEAN)
                mainContainer.getViewTreeObserver().removeOnGlobalLayoutListener(this);
            else
                mainContainer.getViewTreeObserver().removeGlobalOnLayoutListener(this);
        }
    });

    return view;
}
