Answer 1

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

in manifest file

Answer 2

Use <item name="android:windowNoTitle">true</item> in your theme if you want to remove the title bar from all Activity

or

requestWindowFeature(Window.FEATURE_NO_TITLE); if you want to remove the title bar from just one Activity

Answer 3

That is an action bar. To hide the action bar, set the theme attribute in your AndroidManifest.xml file for that particular activity - on which you want to disable the action bar. And yes, you can have buttons in the action bar.

 android:theme="@android:style/Theme.DeviceDefault.NoActionBar.Fullscreen"

Answer 4

You can do this by manifest

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

or if you want to get it done by Activity, use this code in side the onCreate Method,

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    requestWindowFeature(Window.FEATURE_NO_TITLE);

Answer 5

in Activity before setContentView

requestWindowFeature(Window.FEATURE_ACTION_BAR_OVERLAY);
