重写或实现超类型方法[ERROR]

Question

我试图创建一个OnItemClick方法从我的ListView启动另一个活动。一旦创建方法，我就会收到多个错误。错误信息是:

1. LoginList类型的onlisttitemclick (ListView, View, int, long)方法必须覆盖或实现超类型方法

2. 方法onlisttitemclick (ListView, View, int, long)对于FragmentActivity类型是未定义的

   我已经尝试实现另一种方法(如下)，但收到类似的错误。谁能指出我做错了什么吗?

方法:public void onItemClick(AdapterView arg0, View arg1, int arg2, long arg3)

下面是我的Class:

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);
}
} 

Answer 1

扩展FragmentActivity，但不使用fragments

你有两个选择:

第一个创建片段扩展ListFragment，这是你实现onClick方法

Answer 2

我通过选择正确的导入(android.view.View.OnClickListener)解决了这个问题。我导入了"android.content.DialogInterface"。OnClickListener"，这给了我同样的错误
