Remove Title Bar on Android Application
This one’s real simple. If you want to get rid of the title bar in an Android application, you can do it programmatically with:
requestWindowFeature(Window.FEATURE_NO_TITLE);
or in the manifest for your entire application inside the ‘activity’ element with
android:theme="@android:style/Theme.NoTitleBar"
getWindow().setFlags(WindowManager.LayoutParams.NO_STATUS_BAR_FLAG,
WindowManager.LayoutParams.NO_STATUS_BAR_FLAG);
