Java 如何在Android活动中扩展ListActivity

我想使用Activity extends ListActivity for PullToRefresh。但我使用了CustomActionBar，这就是为什么使用AppCompatActivity。如何解决此问题。高级感谢

public class CustomActionActivity extends ListActivity

public class PullToRefreshActivity extends ListActivity {
    private LinkedList<String> mListItems;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.pull_to_refresh);

        // Set a listener to be invoked when the list should be refreshed.
        ((PullToRefreshListView) getListView()).setOnRefreshListener(new PullToRefreshListView.OnRefreshListener() {
            @Override
            public void onRefresh() {
                // Do work to refresh the list here.
                new GetDataTask().execute();
            }
        });

        mListItems = new LinkedList<String>();
        mListItems.addAll(Arrays.asList(mStrings));

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

        setListAdapter(adapter);
    }

根据Java doucmentation的规定，我们不能继承多个类。因此，如果您想同时使用这两种功能，请在布局中使用

ListView

。

如果您想在应用程序中使用ListView，请直接使用它，而不扩展ListActivity。像这样

public class PullToRefreshActivity extends AppCompatActivity {
private LinkedList<String> mListItems;
PullToRefreshListView listView;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.pull_to_refresh);
    listView = (PullToRefreshListView) findViewById(R.id.list_view); 
    // Set a listener to be invoked when the list should be refreshed.
    listView.setOnRefreshListener(new PullToRefreshListView.OnRefreshListener() {
        @Override
        public void onRefresh() {
            // Do work to refresh the list here.
            new GetDataTask().execute();
        }
    });

    mListItems = new LinkedList<String>();
    mListItems.addAll(Arrays.asList(mStrings));

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

    listView.setAdapter(adapter);
}

公共类PullToRefreshActivity扩展了AppCompatActivity{
私有链接列表；
PullToRefreshListView listView；
/**在首次创建活动时调用*/
@凌驾
创建时的公共void（Bundle savedInstanceState）{
super.onCreate（savedInstanceState）；
setContentView（R.layout.pull\u到\u刷新）；
listView=（PullToRefreshListView）findViewById（R.id.list\u视图）；
//设置要在刷新列表时调用的侦听器。
listView.setOnRefreshListener（新的PullToRefreshListView.OnRefreshListener（）{
@凌驾
公共void onRefresh（）{
//请务必刷新此处的列表。
新建GetDataTask（）.execute（）；
}
});
mListItems=新链接列表（）；
addAll（Arrays.asList（mStrings））；
ArrayAdapter=新的ArrayAdapter（此，
android.R.layout.simple_list_item_1，mListItems）；
setAdapter（适配器）；
}
对不起，但是我很难理解这个问题。你能解释清楚吗？在我的活动中，PullToRefresh工作不正常，所以我想使用ListActudio。我已经用PultReRealAc新生编辑了我的文章。考虑使用CurryReVIEW。这是最新的API。
public class PullToRefreshActivity extends AppCompatActivity {
private LinkedList<String> mListItems;
PullToRefreshListView listView;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.pull_to_refresh);
    listView = (PullToRefreshListView) findViewById(R.id.list_view); 
    // Set a listener to be invoked when the list should be refreshed.
    listView.setOnRefreshListener(new PullToRefreshListView.OnRefreshListener() {
        @Override
        public void onRefresh() {
            // Do work to refresh the list here.
            new GetDataTask().execute();
        }
    });

    mListItems = new LinkedList<String>();
    mListItems.addAll(Arrays.asList(mStrings));

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

    listView.setAdapter(adapter);
}
