重写或实现超类型方法[错误]

Question

下面是我的课：

public class LoginList extends FragmentActivity implements OnClickListener, AdapterView.OnItemClickListener, LoaderManager.LoaderCallbacks<Cursor> {

private ListView loginList;
private Button webLogin;
private SimpleCursorAdapter adapter;



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

loginList = (ListView)findViewById(R.id.loginlist);
loginList.setOnItemClickListener(this);

webLogin = (Button)findViewById(R.id.button3);
webLogin.setOnClickListener(this);


//Specify fileds to display in the list
String[] from = new String[] { ListProvider.COLUMN_NAME_SITE };

//Bind fields to listview
int[] to = new int[] {R.id.nameView };

// Create CursorAdapter and set it to display
adapter = new SimpleCursorAdapter(this, android.R.layout.simple_list_item_1, null, from, to);

loginList.setAdapter(adapter);

getSupportLoaderManager().initLoader(0, null, this);      
}

@Override
public void onListItemClick (ListView l, View v, int position, long id) {  // 1.The method onListItemClick(ListView, View, int, long) of type LoginList must override or implement a supertype method

super.onListItemClick (l, v, position, id); //2. The method onListItemClick(ListView, View, int, long) is undefined for the type FragmentActivity

startActivity(new Intent(this, UpdateDeleteLoginList.class)
    .putExtra(ListProvider.COLUMN_ROWID, id));
}

@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
Intent webLoginIntent = new Intent (this, LoginPlusActivity.class);
startActivity(webLoginIntent);
}

@Override
public Loader<Cursor> onCreateLoader(int ignored, final Bundle args) {
return new CursorLoader(this, ListProvider.CONTENT_URI, null, null, null, null);
}

@Override
public void onLoadFinished(Loader<Cursor> loader, Cursor cursor) {
adapter.swapCursor(cursor); 
}

@Override
public void onLoaderReset (Loader<Cursor> loader) {
adapter.swapCursor(null);

}

}

您扩展了FragmentActivity，但没有使用碎片。

您有两个选项：

首先，创建扩展ListFragment的片段，这是您实现onClick方法的时候
