我需要background（Drawable）为我layout创建的item ListView Adapter。要求是在我的Viewgroup构造函数中执行此操作，但我缺少父inflate到private class MAdapter extends CursorAdapter {
private Drawable defaultDrawable;
public MAdapter(Context context, Cursor c, boolean autoRequery) {
super(context, c, autoRequery);
this.defaultDrawable = // here I need to get Drawable which is defined as background for the view which is going to be used for `View` for the list row item
}
。还有其他方法吗？
