如何在Android中獲取OnItemClickListener中的額外數據？

Question

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); 
} 

它應該來自調用列表活動的活動： 這樣的，我有一個活動「hotelAct2.class」裏面我把額外的數據

公共類hotelAct2延伸活動{

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); 
     }}); 

} 然後啓動活動列表是「CairoHotelList.class」我想在活動課

的「p的onItemClickListener額外的數據rogNum「返回0，它應該返回一個從1到20的數字，有幫助嗎？

Answer 1

getIntent方法將返回用於開始當前活動的意圖。它與適配器中的元素完全無關，並且該方法將爲您點擊的每個項目返回相同的值。

爲了澄清你的問題，「progNum」究竟應該從哪裏來？
