從特定活動隱藏工具欄

出於某種原因，我的MainActivity工具欄再次出現（在我從應用程序中刪除所有工具欄後），灰色（應用程序的其餘部分爲藍色）。我想在xml中將其刪除，佈局主題與應用程序的其餘部分完全相同。這就是爲什麼我不確定有什麼問題，並且無法在網上找到任何解決方案。從特定活動隱藏工具欄

風格：

我確保解決方案很簡單，我只是浪費了3個小時試圖找出答案。非常感謝！

How the Toolbar should be

你能發佈MainActivity的整體佈局？或者是全部？ –

我雖然其餘的是無關的，我的壞。我會發布一切，它有點長 –

也許你應該在你的樣式中擴展Theme.AppCompat.NoActionBar？ – Frank

感謝你的幫助，但問題是在清單。我需要選擇清單中的活動的權利的主題，而不是在XML文件（相關清單部分）：

<activity android:name=".MainActivity" 
     android:theme="@style/AppTheme.NoActionBar"> 
     <intent-filter> 
      <action android:name="android.intent.action.MAIN" /> 

      <category android:name="android.intent.category.LAUNCHER" /> 
     </intent-filter> 

    </activity>

try this one 

<style name="AppTheme.FullScreen"> 
    <item name="windowNoTitle">true</item> 
    <item name="windowActionBar">false</item> 
    <item name="android:windowFullscreen">true</item> 
    <item name="android:windowContentOverlay">@null</item>
