{
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

return data.get(position);
}
@Override
public long getItemId(int position) {

Your problem is that you are using setText() with an integer parameter. 您的问题是您正在使用带有整数参数的setText() 。 In this case, Android expects a string resource ID, which is also an integer, so it tries to find the resource with the ID 1, which does not exist of course. 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，这当然是不存在的。
To fix this, you have to pass the parameter as a String . 要解决此问题，您必须将参数作为String传递。 So replace this line: 因此，请替换此行：
holder.tID.setText(employee.getId());
With this: 有了这个：
holder.tID.setText(String.valueOf(employee.getId()));

you need to set using 您需要设置使用
holder.tID.setText(String.valueOf(employee.getId()));
Because what you are doing us setting an integer using setText() would look for string resource but it would not be there and hence will throw an error. 因为您正在做的事情是使用setText()设置整数，因此会查找字符串资源，但它不会存在，因此将引发错误。
