我有一個回收站視圖，該視圖綁定一個雜貨商品。添加該項目的作品完美。但是，當我嘗試刪除該應用程序崩潰的項目時，我得到IndexOutOfBoundsException錯誤。RecyclerView和java.lang.IndexOutOfBoundsException無效的視圖持有者適配器positionViewHolder
我面臨的問題是在我的onBindViewHolder中。我試圖得到適配器的位置，並沒有解決問題。我也剛剛嘗試使用notifyDataSetChanged（）並且剛剛刪除了我的整個列表。
我的問題是我做錯了什麼，我該如何解決這個問題？
下面是Adapter類：
private class GroceryAdapter extends RecyclerView.Adapter<GroceryHolder>{
private List<Grocery> groceries;
private GroceryHolder holder;
public GroceryAdapter(){
setGroceries(GroceryList.get(GroceryActivity.this).getGroceries());
}
public void setGroceries(List<Grocery> groceries){
this.groceries = groceries;
}
@Override
public GroceryHolder onCreateViewHolder(ViewGroup parent, int viewType){
LayoutInflater layoutInflater= LayoutInflater.from(GroceryActivity.this);
View view=layoutInflater.inflate(R.layout.grocery_list_row, parent, false);
holder =new GroceryHolder(view);
return holder;
}
@Override
public void onBindViewHolder(final GroceryHolder holder, final int position){
final Grocery grocery = groceries.get(position);
holder.bindGrocery(grocery);
//private Grocery grocery;
holder.deleteImageButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
GroceryList groceryList = GroceryList.get(getApplicationContext());
groceryList.deleteGrocery(grocery);
groceryAdapter.setGroceries(GroceryList.get(getApplicationContext()).getGroceries());
//holder.getAdapterPosition();
groceryAdapter.notifyItemRemoved(position);
groceryAdapter.notifyItemRangeRemoved(position, groceries.size());
Toast.makeText(getApplicationContext(),"Item deleted", Toast.LENGTH_SHORT).show();
//finish();
}
});
}
@Override
public int getItemCount(){
return groceries.size();
}
}
}
這裏是logcat的
