我认为这将使用此代码

@Override  
public void onCreate(Bundle savedInstanceState) {  
 super.onCreate(savedInstanceState);  
 setContentView(R.layout.main);  

 listGames = (ListView) findViewById(R.id.listViewGame);  
 gamelistArray = getResources().getStringArray(R.array.gameslist);  
 gameDetailsListArray = getResources().getStringArray(  
 R.array.gamesDetails);  

 adapter = new ArrayAdapter<String>(this,  
  android.R.layout.simple_list_item_1, android.R.id.text1,  
 gamelistArray);  

 listGames.setAdapter(adapter);  

 listGames.setOnItemClickListener(new OnItemClickListener() {  

  @Override  
  public void onItemClick(AdapterView<?> parent, View view,  
 int position, long id) {  

// Get the item that was clicked  
Object itemName = listGames.getItemAtPosition(position);  
String keyword = itemName.toString();  
String info = gameDetailsListArray[position];  
Toast.makeText(getApplicationContext(),  
"You have selected:  " + keyword, Toast.LENGTH_SHORT)  
  .show();  
Intent i = new Intent(getBaseContext(),  
  ActivityGameDetails.class);  
i.putExtra("info", info);  
i.putExtra("name", keyword);  
startActivity(i);  

}  
});  
}  
}
