The easiest solution to set the activity as full screen is to set it in the manifest. As an example add the following to your activity section within the manifest:

android:theme="@android:style/Theme.NoTitleBar.Fullscreen"

Therefore it should look something like:

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name" >
    <activity
        android:name=".blahActivity"
        android:label="@string/app_name"
        android:theme="@android:style/Theme.NoTitleBar.Fullscreen" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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

i already use this code but its not work in the case of public void onAttachedToWindow() { this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD); super.onAttachedToWindow(); } this method — Prashant Kadam, Apr 27 '12 at 09:01

Solve Problem using below code

@Override
 public void onAttachedToWindow() {
  // TODO Auto-generated method stub
     super.onAttachedToWindow();  

     handler.postDelayed(mUpdateUiMsg, 100);
    //this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD);     
 }


 public boolean onKeyDown(int keyCode, KeyEvent event) {
  // TODO Auto-generated method stub
  if(keyCode==KeyEvent.KEYCODE_BACK){
   return true;
  }
  if(keyCode==KeyEvent.KEYCODE_HOME){
   return true;
  }

  return super.onKeyDown(keyCode, event);
 }


 private Runnable mUpdateUiMsg = new Runnable() {
        public void run() {


            getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD);


         }
    };

You cannot get full screen with this. – Johann Aug 25 '13 at 07:10 — Johann, Aug 25 '13 at 07:10

  }

  return super.onKeyDown(keyCode, event);
 }


 private Runnable mUpdateUiMsg = new Runnable() {
        public void run() {


            getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD);


         }
    };

In my case,after overridding onAttachedToWindow(),i found overridePendingTransition(int enterAnim, int exitAnim) or

<style name="Theme.NoTitleBar.WithColoredSpinners" parent="@android:style/Theme.NoTitleBar">
    <item name="android:spinnerDropDownItemStyle">@style/SpinnerItem.DropDownItem</item>
    <item name="android:windowAnimationStyle">@style/AnimationActivity</item>
</style>

Did not work, but problem was solved using these code, but I don't know why yet. And the same, I don't know the method onAttachedToWindow() what to do and how it effects?

Try this code before setContentView(xml)

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

Hope, this will work for you.

Had you tried this code, you would have discovered that it doesn't work. You don't get the full screen. – Johann Aug 25 '13 at 07:02
