onClick ListView幫助

Question

好吧，我對Android和編程一般都很陌生。我遵循了Android開發者頁面上的教程來創建列表視圖。現在我真的想用它做點什麼。我有它的工作去一個視圖，但我想列表中的兩個項目，每個去一個不同的活動。這是我已經有的代碼。

package com.pais.convert; 

import android.app.ListActivity; 
import android.content.Intent; 
import android.os.Bundle; 
import android.view.View; 
import android.widget.ArrayAdapter; 
import android.widget.ListView; 

public class list extends ListActivity { 
    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 

     String[] choose = getResources().getStringArray(R.array.list_chooser); 
     setListAdapter(new ArrayAdapter<String>(this, 
       android.R.layout.simple_list_item_1, choose)); 

     ListView lv = getListView(); 
     lv.setTextFilterEnabled(true); 
    } 

    @Override 
    protected void onListItemClick(ListView l, View v, int position, long id) { 
     Intent intent = new Intent(this, tempConvert.class); 
     intent.putExtra("KEY_SELECTED_INDEX", position); 
     startActivity(intent); 
    } 



    } 

我把它去一個不同的活動，但我怎麼能有兩個獨立的項目在ListView每個去不同的活動。但仍然從同一個名單啓動？

感謝所有的幫助。

對於ListActivity，最簡單的方法是在活動本身中重寫onListItemClick。

編輯：

這裏就是我的意思是：

public class test extends ListActivity { 
    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 

     String[] choose = getResources().getStringArray(R.array.list_chooser); 
     setListAdapter(new ArrayAdapter<String>(this, 
       android.R.layout.simple_list_item_1, choose)); 

     ListView lv = getListView(); 
     lv.setTextFilterEnabled(true); 
    } 

    @Override 
    protected void onListItemClick(ListView l, View v, int position, long id) { 
     // Start another activity to do something with the selected item. 
     // I'll assume the other activity is defined in the class 
     // AnotherActivity: 
     Intent intent = new Intent(this, AnotherActivity.class); 
     // now you can add additional information to the intent for the 
     // other activity to use. For instance, to pass just the index of the 
     // selected item, you could code: 
     intent.putExtra("KEY_SELECTED_INDEX", position); 
     // (The string "KEY_SELECTED_INDEX" is an arbitrary string you choose 
     // to name this piece of data. AnotherActivity will use the same name 
     // to retrieve it. Other extras would be added under different names.) 
     startActivity(intent); 
    } 
} 

那麼你就必須定義一個單獨的活動，顯示了第二種觀點：

public class AnotherActivity extends Activity { 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 

     Intent intent = getIntent(); 
     int position = intent.getIntExtra("KEY_SELECTED_INDEX", -1); 
     if (position == -1) { 
      Toast.makeText(this, "No selection to show!", Toast.DURATION_LONG) 
       .show(); 
     } 

     // continue with setting up the activity 
    } 
} 

您還需要添加這是應用程序清單文件的第二個活動。
