RecycleView嵌套EditText,增加删除的时候数据错乱。
在项目中要求使用recycleview嵌套edittext进行输入，点击item中的增加按钮会增加一个item，删除按钮删除当前item，从网上查到一些给edittext设置tag。
下面是我用的方法，我用的adapter：
public class PfUnderlyAddAdapter extends RecyclerView.Adapter<PfUnderlyAddAdapter.MyViewHolder> {
private List<String> mlist;
private Context mcontext;
private List<String> alist = new ArrayList<>();//第一个输入框数据
private List<String> llist = new ArrayList<>();//第二个输入框数据
private List<String> clist = new ArrayList<>();//第三个输入框数据
//点击事件
public interface OnItemDelClickListener{
void onItemDelClick(View view, int position);//删除
void onItemAddClick(View view, int position);//增加
}
private OnItemDelClickListener mOnItemDelClickListener;
public void setOnItemDelClickListener(OnItemDelClickListener mOnItemDelClickListener){
this.mOnItemDelClickListener = mOnItemDelClickListener;
}
public PfUnderlyAddAdapter(List<String> mlist, Context mcontext) {
this.mlist = mlist;
this.mcontext = mcontext;
//初始化数据
for(int i=0;i<mlist.size();i++){
alist.add(i,"");
llist.add(i,"");
clist.add(i,"");
}
}
// 添加数据
public void addData(int position,String msg) {
mlist.add(position, msg);
alist.add(position,"");
llist.add(position,"");
clist.add(position,"");
//添加动画
notifyItemInserted(position);
}
// 删除数据
public void removeData(int position) {
if(position!=0){
mlist.remove(position);
alist.remove(position);
llist.remove(position);
clist.remove(position);
//删除动画
notifyDataSetChanged();
}else{
ToastUtil.showShortToast("最少保留一个");
}
}
//获取数据--
public List<String> getAListData(){
return alist;
}
//获取数据
public List<String> getLListData(){
return llist;
}
//获取数据
public List<String> getCListData(){
return clist;
}
