我正在使用一个弹出式菜单为我的ReyclerView实现取消和启用功能，该菜单调用一个与数据库交互的后端应用程序接口。API工作正常。但是，这些函数会更新列表中的最后一项，而不是所选的项。我该怎么做呢？
我试图从Model定义中获取Id，但也失败了。它返回最后一项的Id。
public void onBindViewHolder(最终RecyclerView.ViewHolder持有者，整型位置){
// Get current position of item in recyclerview to bind data and assign values from list
final MyHolder myHolder= (MyHolder) holder;
current = dataErrand.get(position);
myHolder.service.setText(current.errandservice);
myHolder.date.setText("Date: " + current.erranddate);
myHolder.time.setText("Time: " + current.errandtime);
myHolder.phone.setText("Phone: " + current.errandphone);
myHolder.location.setText("Location: " + current.errandlocation);
myHolder.status.setText("status: " + current.errandstatus);
myHolder.id.setText("Id: "+current.getErrandid());
myHolder.options.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
PopupMenu popup = new PopupMenu(context, myHolder.options);
popup.inflate(R.menu.errand_options);
Menu popMenu = popup.getMenu();
if(current.errandstatus == "Active"){
popMenu.findItem(R.id.errand_reactivate).setVisible(false);
popMenu.findItem(R.id.errand_cancel).setVisible(true);
}
if (current.errandstatus == "Canceled"){
popMenu.findItem(R.id.errand_cancel).setVisible(false);
popMenu.findItem(R.id.errand_reactivate).setVisible(true);
}
popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
@Override
public boolean onMenuItemClick(MenuItem item) {
int menuId = item.getItemId();
if(menuId == R.id.errand_cancel){
//handle menu1 click
//return true;
Toast.makeText(context, " "+current.getErrandid(), Toast.LENGTH_LONG).show();
changeStatus = new ChangeStatus(context);
isChanged = changeStatus.makeChange(current.errandid,0 );
if(isChanged == true){
current.errandstatus = "Canceled";
myHolder.status.setText("status: " + current.errandstatus);
}
//return true;
}
if(menuId ==R.id.errand_reactivate){
Toast.makeText(context, " "+current.getErrandid(), Toast.LENGTH_LONG).show();
changeStatus = new ChangeStatus(context);
isChanged = changeStatus.makeChange(current.errandid, 1);
if(isChanged == true){
current.errandstatus = "Active";
myHolder.status.setText("status: " + current.errandstatus);
}
//return true;
}
return false;
}
});
popup.show();
}
});OnMenuItemClick应将项目Id和预期的更改转发给后端API.enter镜像描述
