ListView는 항목을 클릭 할 때 활동을 엽니 다?

Question

Im은 ListView와보기의 항목을 클릭 할 때 호출되는 다른 여러 가지 활동으로 구성된이 앱을 만들려고합니다. 그러나 주 활동에 onclicklistener 작업을 구현할 수 없습니다. 아래 코드를 사용하여 활동을 열 수 없습니다.

을 heres 코드 :

public void setOnItemClickListener(AdapterView<?> parent, View view, 
     int position, long id) { 
    switch(position) 
    { 
     case 0: Intent newActivity0 = new Intent(this, TempuraActivity.class);  
       startActivity(newActivity0); 
       break; 
     case 1: Intent newActivity1 = new Intent(this, TempuraActivity.class);  
       startActivity(newActivity1); 
       break; 
     case 2: Intent newActivity2 = new Intent(this, TempuraActivity.class);  
       startActivity(newActivity2); 
       break; 
     case 3: Intent newActivity3 = new Intent(this, TempuraActivity.class);  
       startActivity(newActivity3); 
       break; 
     case 4: Intent newActivity4 = new Intent(this, TempuraActivity.class);  
       startActivity(newActivity4); 
       break; 
    } 
}

UPDATE

변경

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

protected void onListItemClick(ListView l, View v, int position, long id) { 

하고 그것을 작동합니다.

ORIGINAL

귀하의 코드는 setOnItemClickListener이있는, 조금 혼란하지만 실제로는 방법에게 onItemClickListener 객체 (또는 익명 클래스)를 통과해야합니다.

아마도 ListActivity에서 이와 같은 것을 찾고있을 것입니다.

final ListView listView = getListView(); 
listView.setOnItemClickListener(new OnItemClickListener() { 
    @Override 
    public void onItemClick(AdapterView<?> paramAdapterView, View paramView, int paramInt, 
      long paramLong) { 
     switch(position) 
{ 
    case 0: Intent newActivity0 = new Intent(YourActivity.this, TempuraActivity.class);  
      startActivity(newActivity0); 
      break; 
    case 1: Intent newActivity1 = new Intent(YourActivity.this, TempuraActivity.class);  
      startActivity(newActivity1); 
      break; 
    case 2: Intent newActivity2 = new Intent(YourActivity.this, TempuraActivity.class);  
      startActivity(newActivity2); 
      break; 
    case 3: Intent newActivity3 = new Intent(YourActivity.this, TempuraActivity.class);  
      startActivity(newActivity3); 
      break; 
    case 4: Intent newActivity4 = new Intent(YourActivity.this, TempuraActivity.class);  
      startActivity(newActivity4); 
      break; 
}    
    } 
}); 

은 여기에서 onItemClickListener의 onItemClick 방법 내부 스위치 문을 구현할 수 있으며 작동합니다.

참고 : 내부 클래스 내부에 있으므로 외부 활동 클래스를 참조해야하므로 this을 YourActivity로 변경해야합니다.

또는 당신 onListItemClick 무시할 수 :

@Override 
protected void onListItemClick(ListView l, View v, int position, long id) { 
    // ... put switch statement here 
} 

을 목록 활동에서 getListView()
