public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
   // TODO Auto-generated method stub
    Bundle programNum = getIntent().getExtras();
    final int progNum = programNum.getInt("Program");
    Intent intent = new Intent(getBaseContext(), hotelAct3.class);
    String hotelName = (String) ((TextView)parent.getChildAt(position)).getText();
    startActivity(intent);
}

它应该来自调用列表活动的活动：这样我就有一个活动“hotelAct2.class”在里面我放了额外的数据

公共类hotelAct2扩展活动{

EgyptDataSource datasource;
MySQLiteHelper sqlHelper;
ArrayAdapter<Hotel> hotelAdapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.hotelq2);
    Bundle programNum = getIntent().getExtras();
    final int progNum = programNum.getInt("Program");
    final String Srating = programNum.getString("Stars");
    //Intent ratingIntent = getIntent();
    //String Srating = ratingIntent.getStringExtra("Stars");

    Toast.makeText(hotelAct2.this, "The program is " + progNum + " The rating is " + Srating, Toast.LENGTH_LONG).show();

    RadioButton nileRB = (RadioButton) findViewById(R.id.hRB2a);
    RadioButton pyramidsRB = (RadioButton) findViewById(R.id.hRB2b);
    RadioButton downtownRB = (RadioButton) findViewById(R.id.hRB2c);
    RadioButton letmeRB = (RadioButton) findViewById(R.id.hRB2d);

    if(Srating.equals("Five"))
    {
    nileRB.setOnClickListener(new OnClickListener(){

        public void onClick(View v) {
            // TODO Auto-generated method stub
            Intent i = new Intent(hotelAct2.this, CairoHotelList.class);
            i.putExtra("RB", "nile5");
            i.putExtra("program", progNum);
            startActivity(i);
        }});

然后它启动“CairoHotelList.class”的活动列表我想在活动类的onItemClickListener中获取额外的数据

“progNum”返回 0，而它应该返回一个从 1 到 20 的数字，有什么帮助吗？

该getIntent方法将返回用于启动当前活动的意图。它与适配器中的元素完全无关，并且该方法将为您单击的每个项目返回相同的值。

为了澄清你的问题，“progNum”究竟应该从哪里来？
