Hiding Android title bar only in landscape mode

Question

I have an activity and want to have these conditions:

• My activity has title bar in portrait mode.
• The title bar will hide when I turn the device to go to landscape mode.
• The activity should not to recreate when goes to landscape mode, by using "configChanges" in Manifest.

I know this question is asked before, but no correct answer I found.

Answer 1

Add in style.xml

<style name="generalnotitle" parent="Theme.AppCompat.Light" >
    <item name="android:windowNoTitle">true</item>   <!-- //this -->
</style>

add in manifiest file Activity ,

  android:theme="@style/generalnotitle">

To get Orientation of Device

 int display_mode = getResources().getConfiguration().orientation;


if (display_mode == Configuration.ORIENTATION_LANDSCAPE) {

        getSupportActionBar().hide(); //<< this

    } else {



    }

setContentView(R.layout.activity_main);

Landscape mode without Title bar
