我知道应用程序崩溃是因为我的自定义 titleBar 和 ActionBar 之间的冲突。但我无法理解的是为什么即使我没有实现 CustomView 也无法使用 ActionBar.newTab().setText(categoryList[0])

这是我的自定义标题栏样式：

 <resources>
  <style name="CustomWindowTitleBackground">
    <item name="android:background">#323331</item>
  </style>

  <style name="CustomTheme" parent="android:Theme">
    <item name="android:windowTitleSize">35dip</item>
    <item name="android:windowTitleBackgroundStyle">@style/CustomWindowTitleBackground</item>
  </style>
 </resources>

 /***

我的活动中的代码：

public class TestingEndlessAdapterFragmentDemo extends Activity implements
    ActionBar.TabListener {
private TestingEndlessAdapterFragment simple = null;
private TestingEndlessAdapterCustomTaskFragment customTask = null;

private static enum Tabs {
    TAB_FUN, TAB_MOVIE, TAB_STANDUP, TAB_MUSIC;
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    getWindow().requestFeature(Window.FEATURE_ACTION_BAR); 

    final ActionBar bar = getActionBar();
    // titlebar_title.setText("Prefeerences");
    // titlebar_icon.setImageResource(R.drawable.titlebar_list);

    bar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);

    String[] categoryList = new String[4];

    categoryList = getResources().getStringArray(R.array.category_name);

    bar.addTab(bar.newTab().setText(categoryList[0]).setTabListener(this)
            .setTag(Tabs.TAB_FUN));
    bar.addTab(bar.newTab().setText(categoryList[1]).setTabListener(this)
            .setTag(Tabs.TAB_MOVIE));
    bar.addTab(bar.newTab().setText(categoryList[2]).setTabListener(this)
            .setTag(Tabs.TAB_STANDUP));
    bar.addTab(bar.newTab().setText(categoryList[3]).setTabListener(this)
            .setTag(Tabs.TAB_MUSIC));


}

public void onTabReselected(Tab tab, FragmentTransaction ft) {
    onTabSelected(tab, ft);
}

public void onTabSelected(Tab tab, FragmentTransaction ft) {
    switch ((Tabs) tab.getTag()) {
    case TAB_FUN:
        showSimple(ft);
        break;
    case TAB_MOVIE:
        showCustom(ft);
        break;
    case TAB_STANDUP:
        showCustom(ft);
        break;
    case TAB_MUSIC:
        showCustom(ft);
        break;
    }
}

public void onTabUnselected(Tab tab, FragmentTransaction ft) {
    // no-op
}

private void showSimple(FragmentTransaction ft) {
    if (simple == null) {
        simple = new TestingEndlessAdapterFragment();
    }

    ft.replace(android.R.id.content, simple);
}

private void showCustom(FragmentTransaction ft) {
    if (customTask == null) {
        customTask = new TestingEndlessAdapterCustomTaskFragment();
    }

    ft.replace(android.R.id.content, customTask);
}

}

一切正常，除了 setText()
