Android-无法自定义activity的titlebar

Question

想重写一个activity的titleBar,使用Window.FEATURE_CUSTOM_TITLE，可是运行的时候总是出现这个bug:
You cannot combine custom titles with other title feature

代码如下：

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);   
requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
this.getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.workorder_list_titlebar);
setContentView(R.layout.workorder_list);
setListAdapter(new ArrayAdapter(this,R.layout.workorder_list, R.id.label,orders));    
}

Answer 1

在theme.xml中删除这行：

<item name="android:windowNoTitle">true</item>

或者改成：

 <item name="android:windowActionBar">false</item>
