Here's a my pattern (creating a custom ViewGoup here, but still):

// CustomView.java

public class CustomView extends LinearLayout {

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

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

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

    private void init(Context ctx) {
        LayoutInflater.from(ctx).inflate(R.layout.view_custom, this, true);
            // extra init
    }

}

and

// view_custom.xml
