title: How to hide the title bar in a particular activity style by overriding the Application Style
body: <p>I want to override a application theme on a particular activity, but its not working for me</p>
  
  <p>This is code on my Manifest.xml:</p>
  
  <pre><code> &lt;application
      android:allowBackup="true"
      android:icon="@drawable/ic_launcher"
      android:label="@string/app_name"
      android:theme="@style/Theme.Sherlock.Light" &gt;
      &lt;activity
          android:theme="@style/MyTheme"
          android:name="com.ssdevnet.Splash"
          android:label="@string/app_name" &gt;
          &lt;intent-filter&gt;
              &lt;action android:name="android.intent.action.MAIN" /&gt;
              &lt;category android:name="android.intent.category.LAUNCHER" /&gt;
          &lt;/intent-filter&gt;
      &lt;/activity&gt;
      &lt;activity 
      android:name="com.ssdevnet.Home"
      android:label="@string/app_name" /&gt;
  &lt;/application&gt;
  </code></pre>
  
  <p>And this is what i used in style:</p>
  
  <pre><code>&lt;style name="MyTheme" parent="Theme.Sherlock.Light.DarkActionBar"&gt;
          &lt;item name="android:windowNoTitle"&gt;true&lt;/item&gt;
      &lt;/style&gt;
  </code></pre>
  
  <p>and its still not working on Android 2.3.6 or below but working on 3 and above.</p>
  
  <p>Also i tried to use this on the oncreate method on class file for that particular page:</p>
  
  <pre><code>requestWindowFeature(Window.FEATURE_NO_TITLE);// Removes title bar
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,     WindowManager.LayoutParams.FLAG_FULLSCREEN);    // Removes notification bar
  </code></pre>
  
  <p>but its not working on my phone running Android 2.3.6 but its working on Emulator running Jellybean and i need something that works on all the versions.</p>
  
  <p>And I need to know some things as i am a newbie to android:
  Can we define a Global theme, and override that theme on some activities? if yes, what method can we use?</p>
  
  <p>Or we have to define theme for every activity if we are targeting activities instead of app?</p>
  
  <p>I also want to learn about deploying the custom themes in the app.. if there are some good tutorials and references please share.</p>
  
  <p>Thanks in Advance!</p>
