java - 当 ListView 中有多个项目时，读取所选项目的文本

Question

我自定义了一个带有 ListView 的适配器，每个列表项中有四个项目:

TextView id = tid
TextView id = tname
TextView id = tgender
TextView id = tage

现在单击时，我想从 ID 为“tid”的项目的 TextView 中获取文本。

public class TeacherAdapter extends ArrayAdapter <Teacher>{

private LayoutInflater inflater;
private ArrayList<Teacher> teachers;

public TeacherAdapter(Context context, ArrayList<Teacher> teachers) {
    super(context, 0, teachers);
    inflater = LayoutInflater.from(context);
    this.teachers = teachers;
}

public int getCount() {
    return teachers.size();
}

public Teacher getItem(int position) {
    return teachers.get(position);
}

public long getItemId(int position) {
    return position;
}

private static class ViewHolder {
    TextView txtName;
    TextView txtMobile;
    TextView txtDept;
    TextView txtId;
}

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

    ViewHolder viewHolder;

    if (convertView == null) {
        viewHolder = new ViewHolder();
        convertView = inflater.inflate(R.layout.teacher_text_item, null);

        viewHolder.txtName = (TextView) convertView.findViewById(R.id.tName);
        viewHolder.txtMobile = (TextView) convertView.findViewById(R.id.tMobile);
        viewHolder.txtDept = (TextView) convertView.findViewById(R.id.tDepartment);
        viewHolder.txtId = (TextView) convertView.findViewById(R.id.tId);
        convertView.setTag(viewHolder);
    }
    else {
        viewHolder = (ViewHolder) convertView.getTag();
    }


    viewHolder.txtName.setText(teachers.get(position).getName());
    viewHolder.txtMobile.setText(teachers.get(position).getMobile());
    viewHolder.txtDept.setText(teachers.get(position).getDepartment());
    viewHolder.txtId.setText(teachers.get(position).getId()+"");

    return convertView;
}
}

我在多个 ListView 中有四个项目:名称、手机号码、部门、ID。我想要做的只是在单击列表项时从列表项中获取getId。

这段代码解决了我的问题。

 @Override
protected void onListItemClick(ListView l, View v, int position, long id) {
    super.onListItemClick(l, v, position, id);

    if (v != null){
        TextView textView = (TextView)v.findViewById(R.id.tId);
        Log.e("idthatclicked",textView.getText().toString());
    }
}
