ListView 충돌 응용

Question

매우 간단하게 만들려고합니다. ListView하지만 불행히도 응용 프로그램이 끊어 질 때마다 만듭니다.

import android.app.ListActivity; 
import android.os.Bundle; 
import android.util.Log; 
import android.view.View; 
import android.widget.AdapterView; 
import android.widget.AdapterView.OnItemClickListener; 
import android.widget.ArrayAdapter; 
import android.widget.ListView; 

public class MainActivity extends ListActivity implements OnItemClickListener { 

    public static String[] daysArray = {"Ponedeljek", "Torek", "Sreda", "Četrtek", "Petek", "Sobota", "Nedelja"}; 

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

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

     setListAdapter(adapter); 

     ListView lv = getListView(); 
     lv.setOnItemClickListener(this); 

    } 

    @Override 
    public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) { 
     // TODO Auto-generated method stub 
     Log.i("Info", "CLICKED"); 
    } 

} 

레이아웃 main.xml에 : 이 내 코드입니다

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" > 

    <ListView android:id="@+id/listView" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" /> 

</RelativeLayout>

Answer 1

필요 :

android:id="@+id/listView" 

당신이 ListActivity를 사용하는 경우. 또는 ListActivity가 아닌 Activity를 사용하려고 시도하십시오.

EDIT : my code; 레이아웃 :

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
       android:orientation="vertical" 
       android:layout_width="match_parent" 
       android:layout_height="match_parent"> 
    <ListView android:id="@android:id/list" 
       android:layout_width="match_parent" 
       android:layout_height="match_parent"/> 
... 

그리고 내 클래스

:

public class AnyNameHere extends ListActivity { 
    @Override 
    protected void onCreate (Bundle savedInstanceState) { 
     super.onCreate (savedInstanceState); 
     setContentView (R.layout.listview); 
      // do what you want here; 
} 

하고 :)

Answer 2

당신이 ListActivity을 확장하고 있습니다. ListView은

android:id="@android:id/list" 

(id)이어야합니다.

Answer 3

setContentView 메서드 호출 때문에. 대신

android:id="@android:id/list" 

를 사용하는

Answer 4

당신이있는 거 목록보기 일하고 잘못된 ID가 있습니다. documentation에서 다음과 같이 MainActivity로, 다음 ListView XML은 list으로 android:id를 확인해야

당신이 당신의 활동을 만들 entend ListActivity하려는

To do this, your own view MUST contain a ListView object with the id "@android:id/list" (or list if it's in code)

Answer 5

, ...

<ListView 
    android:id="@+id/list" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" />
