無法刪除標題欄Android應用程序

Question

使用「設置」按鈕刪除標題欄時出現嚴重問題。 當我嘗試刪除它與代碼：android：theme =「@ android：style/Theme.NoTitleBar.Fullscreen」>或相似我得到應用程序崩潰。

應用程序由啓動屏幕和Web視圖活動組成。

這裏是代碼：

Android清單：

試試這個

變化從程序兼容性主題的基本應用主題到Android主題，創造一個新的主題閃屏。

<resources> 
<!-- Base application theme. --> 
<style name="AppTheme" parent="android:Theme.DeviceDefault.Light.DarkActionBar"> 
    <!-- Customize your theme here. --> 
</style> 

<!-- Splash screen theme. --> 
<style name="SplashTheme" parent="android:Theme.DeviceDefault.Light.NoActionBar"> 
    <!-- Customize your theme here. --> 
</style> 
</resources> 

現在使你的MainActivity擴展活動，而不是ActionBarActivity

public class MainActivity extends Activity { 

打開menu_main.xml和改變

app:showAsAction="never" 

到

android:showAsAction="never" 

在AndroidManifest.xml集主題對於閃屏如下

​​

從SplashScreen.java

requestWindowFeature(Window.FEATURE_NO_TITLE); 
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
     WindowManager.LayoutParams.FLAG_FULLSCREEN); 

刪除這些行，你會得到你想要的東西。你得到的錯誤是因爲你正在從一個活動切換到ActionBarActivity
