은 내가 entend의 ​​ListActivity를 해달라고!

3 jave 파일 :

"public class MainActivity extends PreferenceActivity implements OnClickListener" 

"public class QuickPrefsActivity extends PreferenceActivity" 

"public class ShowSettingsActivity extends Activity" 

그래서 난 문제가 어디에서 오는지 undertand에 그나마

는 난 단지가?

Answer 1

당신은 여전히 ​​ListActivity를 사용하려는 경우이 오류를 해결할 수

RuntimeException: Your content must have a ListView whose id attribute is 'android.R.id.list'

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

참조하십시오.
