我不entend ListActivity！

我只有：

3 java的文件：

"public class MainActivity extends PreferenceActivity implements OnClickListener" 

"public class QuickPrefsActivity extends PreferenceActivity" 

"public class ShowSettingsActivity extends Activity" 

，所以我不undertand問題出在哪裏從何而來？

Answer 1

請參閱

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"/> 

這將解決這個錯誤，如果你仍然想使用ListActivity。
