How to assign an id to list items?

Question

Java

I want to open a new activity when I click on a list item.
The list is formed like this:

for (int i = 0; i < name.length; i++) {
      Log.d("myLogs", "i = " + i);
      View item = ltInflater.inflate(R.layout.item, linLayout, false);
      TextView tvName = (TextView) item.findViewById(R.id.tvName);
      tvName.setText(name[i]);
      TextView tvPosition = (TextView) item.findViewById(R.id.tvPosition);
      tvPosition.setText("Должность: " + position[i]);
      TextView tvSalary = (TextView) item.findViewById(R.id.tvSalary);
      tvSalary.setText("Оклад: " + String.valueOf(salary[i]));
      item.getLayoutParams().width = LayoutParams.MATCH_PARENT;
      item.setId(i+1);
      item.setOnClickListener(this);
      item.setBackgroundColor(colors[i % 2]);
      linLayout.addView(item);
    }
public void onClick(View v) {
    switch (v.getId()) {
    case R.id.1:
      Intent intent = new Intent(this, ActivityTwo.class);
  startActivity(intent);
      break;
    default:
      break;
    }
  }

It turns out that the first TextView is assigned id 1. But, idea says that there is an error in the case R.id.1: line. However, the code is working. If instead of 1 you put another id assigned manually, not in a loop, then everything works. Ids are also assigned, I tried to display them through println () - everything works. So how to work out clicking on id?
