android报错No adapter attached, skipping layout情况之一

报错情况之一: **mInventoryList.clear();清除适配器缓存的 方法应该放在接口回调数据的后面，因放在了前面还没加载出数据就清除了集合:虚拟机执行代码从上到下执行的呢:**  
放在: mInventoryList = data.getData();后面就ok了

//库存列表
        void inventoryList() { 
    
            ApiClient.inventoryList(0, 100, new BaseObserver<BaseResponse<List<InventoryResponse>>>(this) { 
                @Override
                protected void onBaseError(Throwable t) { 
                    Log.d(TAG, "ERROR");
                }
    
                @Override
                protected void onBaseNext(BaseResponse<List<InventoryResponse>> data) { 
                    if (data.getData() == null) { 
                        return;
                    }
                    mInventoryList.clear();//**错误写法，数据还没加载就清除集合**
                    mInventoryList = data.getData();
                    tvMaterialName.setText(StringUtils.formatStr(mInventoryList.get(0).getMaterialName()));
    
                    //库存列表适配器
                    mInventoryQueryAdapter = new InventoryQueryAdapter(InventoryQueryActivity.this, mInventoryList);
                    //添加适配器
                    mRecyclerInventory.setAdapter(mInventoryQueryAdapter);
