     super.onCreate(savedInstanceState);

}

崩潰我的應用程序錯誤如何正確隱藏活動標題中安卓

android.util.AndroidRuntimeException: requestFeature() must be called before adding content

我知道我有設定內容畫面之前請求窗口功能，這就是我在做什麼。爲什麼錯誤仍然存在？

我Acitivty延伸AppCompatActivity，並宣佈在清單如下：

<activity 
      android:name=".activity.CameraActivity" 
      android:label="@string/title_activity_camera" 
      android:theme="@style/Theme.AppCompat.Light.Dialog"></activity>

將錯誤記錄放在此處 –

如果您要擴展應用程序活動，請將其替換爲活動並檢查您的代碼。 –

我認爲你需要閱讀這個網址，它確實有解決你的問題，http://android-developers.blogspot.in/2013/08/actionbarcompat-and-io-2013-app-source.html –

必須super.onCreate之前調用requestFeature。有必要super.onCreate（）之前調用requestFeature（）之前super.onCreate

@Override 
    protected void onCreate(Bundle savedInstanceState) { 
     requestWindowFeature(Window.FEATURE_NO_TITLE); 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
}

沒有錯誤，但標題仍然可見 – 4ndro1d

你可以添加圖像的帖子？這會更有幫助 –

通話requestWindowFeature取代你的代碼，你可以試試這個：

<style name="Theme.AppCompat.Light.NoActionBar.FullScreen" parent="@style/Theme.AppCompat.Light"> 
    <item name="windowNoTitle">true</item> 
    <item name="windowActionBar">false</item> 
    <item name="android:windowFullscreen">true</item> 
    <item name="android:windowContentOverlay">@null</item> 
</style>

希望這會幫助你。

     requestWindowFeature(Window.FEATURE_NO_TITLE);    
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main);
