1. No view found for id Fragment

由于业务需要，项目中做了一个fragment的组件专门用来执行选图显示上传功能模块，由于表单需要，需要将组件放在RecycleView(该方法不推荐，但是奈何短期要解决问题不方便大改),在嵌入过程中报错No view found for id Fragment ，查询了源代码，大概分析了一下，可能是recyclerView的复用问题。
出错源代码：

if (!mFragment.mRestored) {
                    String resName;
                    try {
                        resName = mFragment.getResources().getResourceName(mFragment.mContainerId);
                    } catch (Resources.NotFoundException e) {
                        resName = "unknown";
                    }
                    throw new IllegalArgumentException("No view found for id 0x"
                            + Integer.toHexString(mFragment.mContainerId) + " ("
                            + resName + ") for fragment " + mFragment);
                }

解决方案：

// 每个fragment设置独立的ID，同时ID仅赋值一次，保证id 唯一，此代码在convert holder中
if (!item.isGenerated) {
           view.id = View.generateViewId()
           item.isGenerated = true
       }
//监听view 的Attach 方法，当attach 的时候添加时候执行commit方法
view.addOnAttachStateChangeListener(object : View.OnAttachStateChangeListener {
           override fun onViewAttachedToWindow(v: View?) {
               view.removeOnAttachStateChangeListener(this)
              //添加fragment 
               val fragment = PhotoFragment()
               fragment!!.setmMaxCount(5)
               val bundle = Bundle()
               bundle.putInt(PhotoFragment.ACTION, item.type)
               bundle.putString(Constants.NAME, item.desc)
               bundle.putParcelableArrayList(Attachment.ATTACHMENTS, item.attachList)
               item.fragment!!.arguments = bundle
               val transaction = fragmentManager.beginTransaction()
               transaction.replace(
                   view.id,
                   item.fragment!!
               )
               if (!item.fragment!!.isAdded) {
                   transaction.commitNowAllowingStateLoss()
              }
           }

           override fun onViewDetachedFromWindow(v: View?) {
           }
       })
