全屏显示Layout，怎么隐藏标题栏

我要全屏显示一个layout，不显示标题栏的那种。onCreate代码里已经设置了 FLAG_FULLSCREEN 还是不行，标题栏还是在。

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setContentView(R.layout.home);
    }

求高手看看，这段代码有什么问题，要隐藏标题栏该怎么弄

试试这个：

public class MainActivity extends Activity {  
 
    @Override  
    public void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState); 
        // 隐去状态栏部分
        this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);  
        // 隐去标题栏
        this.requestWindowFeature(Window.FEATURE_NO_TITLE);  
 
        setContentView(new MyView(this));   
    }  
}

设置应用的manifest里 android:theme

<application
        android:icon="@drawable/ic_launcher"
        android:label="@string/name"
        android:theme="@android:style/Theme.NoTitleBar" >
