ListView中的SwitchCompat进行网络调用

SwitchCompat in ListView to make network call

我在 listView 项中有 SwitchCompat,我希望每次更改它时将此 SwitchCompat 状态发送到我的远程数据库 ON/OFF 对于特定项,我尝试将此网络调用放入适配器中但我得到了异常:NetworkOnMainThreadException

有什么帮助吗?

我正在使用 Retrofit 进行网络调用

我的适配器

Adapter.java

public View getView(int position, View convertView, ViewGroup parent) {
    View row = convertView;
    ExpensesHolder holder = null;
    if (row == null) {
        LayoutInflater inflater = ((Activity) mContext).getLayoutInflater();
        row = inflater.inflate(layoutResourceId, parent, false);
        holder = new ExpensesHolder();
        ...
        row.setTag(holder);

    } else {
        holder = (ExpensesHolder) row.getTag();
    }
    holder.switchExpenses.setTag(position);
    ...
    if (flag.equals("unselected")) {
        holder.switchExpenses.setChecked(false);

    } else {
        holder.switchExpenses.setChecked(true);

    }
    if (TextUtils.isEmpty(expName)) {
        // want to make network call here
        }




    return row;

}

可能您正在调用 call.execute(),为避免 NetworkOnMainThreadException 使用 call.enqueue(listener)
