当我调用我的自定义列表视图适配器时，我的应用程序失败

Question

当我调用我的自定义适配器构造函数时，它没有显示错误，但是当我调用 setAdapter 时，它终止了我的应用程序

ListView listView =(ListView)findViewById(R.id.slistview);
        EmployeeListAdapter suerveryAdapter= new EmployeeListAdapter(SuerveyUserActivity.this,arrayList,getResources());
       listView.setAdapter(suerveryAdapter);

我的自定义适配器 class 代码是

public class EmployeeListAdapter extends BaseAdapter {

private Activity activity;
private ArrayList<serveyData> data;
private static LayoutInflater layoutInflater = null;
public Resources res;
serveyData employee;

public EmployeeListAdapter(Activity a,ArrayList d,Resources r)
{
    activity = a;
    data = d;
    res = r;
    layoutInflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    /*for (serveyData e : data) {
        String NameAndEmail = data.size()+"000"+e.getId() + "," + e.getName()+ "," +e.getDesciption();
        Toast.makeText(activity, NameAndEmail,Toast.LENGTH_SHORT).show();
    }*/

}

@Override
public int getCount() {
    return data.size();
}

@Override
public Object getItem(int position) {
    return data.get(position);
}

@Override
public long getItemId(int position) {
    return 0;
}

public class ViewHolder
{
    public TextView tID;
    public TextView tName;
    public Button bDelete;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {

    View v1 = convertView;

    final ViewHolder holder;

    if(convertView == null)
    {
        v1 = layoutInflater.inflate(R.layout.single_item,null);
        holder = new ViewHolder();
        holder.tID = (TextView) v1.findViewById(R.id.tvID);
        holder.tName = (TextView) v1.findViewById(R.id.tvName);
        holder.bDelete = (Button) v1.findViewById(R.id.btnDelete);
        v1.setTag(holder);
    }
    else
    {
        holder = (ViewHolder)v1.getTag();
    }

    if(data.size() < 1)
    {
        holder.tName.setText("No Data Found");
        holder.bDelete.setVisibility(View.GONE);
    }
    else
    {
        employee = new serveyData();
        employee = (serveyData) data.get(position);
        holder.tID.setText(employee.getId());
        holder.tName.setText(employee.getName());

        holder.bDelete.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                /*Intent i = new Intent(activity, AddEmployee.class);
                        activity.startActivity(i);*/
            }
        });
    }

    return v1;
}}

我将 arraylist 传递给了我的自定义适配器 class，所以请帮忙

Answer 1

您的问题是您将 setText() 与整数参数一起使用。在这种情况下，Android 需要一个字符串资源 ID，它也是一个整数，因此它会尝试查找 ID 为 1 的资源，当然它不存在。

要解决此问题，您必须将参数作为 String 传递。所以替换这一行：

holder.tID.setText(employee.getId());

有了这个：

holder.tID.setText(String.valueOf(employee.getId()));

Answer 2

您需要使用

进行设置

holder.tID.setText(String.valueOf(employee.getId()));

因为你在做什么，我们使用 setText() 设置一个整数会寻找字符串资源，但它不会在那里，因此会抛出错误。
