回调函数使用

ItemMenuAdapter adapter = new ItemMenuAdapter(ItemSearchActivity.this,mMenuItemList,mStoreModel,new ItemMenuAdapter.OnMenuSelectCallBack() {@Overridepublic void onCallBack() {// 在adapter中调用onMenuSelectCallback.onCallBack();时调用到activity里的方法.}});

在adapter中定义OnMenuSelectCallBack接口

public interface OnMenuSelectCallBack {public void onCallBack();} 

   private OnMenuSelectCallBack onMenuSelectCallback;    public ItemMenuAdapter(Context context,OnMenuSelectCallBack onMenuSelectCallback) {          this.context = context;          this.onMenuSelectCallback = onMenuSelectCallback;    }
