android jdk扩展,java – 如何在Android Activity中扩展ListActivity AppCompatActivity

我想使用Activity扩展ListActivity for PullToRefresh.But我使用CustomActionBar这就是使用AppCompatActivity.How来解决这个问题的原因.谢谢你在Advanced中

public class CustomActionActivity extends ListActivity

public class PullToRefreshActivity extends ListActivity {

private LinkedList 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();

mListItems.addAll(Arrays.asList(mStrings));

ArrayAdapter adapter = new ArrayAdapter(this,

android.R.layout.simple_list_item_1, mListItems);

setListAdapter(adapter);

}

而不是这个：

public class CustomActionActivity extends AppCompatActivity
