StaggeredGridLayout管理器删除项目后，项目分散

我正在使用交错的网格布局显示数据，以从数据库回收视图。我遇到了一个问题，从db删除项目以及从适配器删除位置后，我得到一些物品渲染问题。像散落在各处。这里是我的代码StaggeredGridLayout管理器删除项目后，项目分散

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_note_favorite); 
    ButterKnife.bind(this); 
    toolbar = (Toolbar) findViewById(R.id.fav_note_toolbar); 
    setSupportActionBar(toolbar); 

    noteAdapter = new NoteAdapter(noteModelList, NoteFavoriteActivity.this); 
    layoutManager = new StaggeredGridLayoutManager(2, StaggeredGridLayoutManager.VERTICAL); 
    recyclerView.setLayoutManager(layoutManager); 
    recyclerView.setItemAnimator(new DefaultItemAnimator()); 
    recyclerView.setAdapter(noteAdapter); 
    touchListenerRecycler(); 
    loadDataAll(); 


} 
private void loadAll() { 
    noteModelList.clear(); 

    DBManagerFav dbManagerFav = DBManagerFav.getInstance(NoteFavoriteActivity.this); 
    dbManagerFav.openDataBase(); 
    noteModelList = dbManagerFav.getAllNoteList(); 
    Log.i(TAG, " size : " + noteModelList.size()); 
    noteAdapter = new NoteAdapter(noteModelList, NoteFavoriteActivity.this); 
    recyclerView.setAdapter(noteAdapter); 
    noteAdapter.notifyDataSetChanged(); 

    dbManagerFav.closeDataBase(); 

} 


private void deleteOperation() { 

    DBManagerFav dbManagerFav = DBManagerFav.getInstance(NoteFavoriteActivity.this); 
    dbManagerFav.openDataBase(); 

    NoteModel noteModel = new NoteModel(); 
    noteModel.setId(noteModelList.get(adapterClickedPosition).getId()); 

    int status = dbManagerFav.deleteNote(noteModelList.get(adapterClickedPosition).getId()); 
    if (status > 0) { 

     noteAdapter.removeAt(adapterClickedPosition); 

    } 
    dbManagerFav.closeDataBase(); 
    loadDataAll(); 
} 
//this belongs to adapter 
public void removeAt(int position) { 
    Log.d(TAG, " removing at position : " + position); 
    noteModelList.remove(position); 
    notifyItemRemoved(position); 
    notifyItemRangeChanged(position, noteModelList.size()); 
    notifyDataSetChanged(); 
}

我附上两个截图前后后删除项目

删除'notifyDataSetChanged（）;'从** RemoveAt移除（ int position）**方法 –

@Nilesh，感谢回复，让我快速浏览 – Avinash

@Nilesh，它不起作用 – Avinash

你可以在里面放loadDataAll（）{

layoutManager = new StaggeredGridLayoutManager(2, StaggeredGridLayoutManager.VERTICAL); 
    recyclerView.setLayoutManager(layoutManager);

// ........ } 瞧..

谢谢它的工作原理，我试图与invalidateSpan但我错过了这个通知布局后重新加载 – Avinash
