Answer 1

In styles.xml file, change DarkActionBar to NoActionBar

    <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>

Answer 2

In the manifest file change to this:

android:theme="@style/Theme.AppCompat.Light.NoActionBar" >

Answer 3

Go to Project -> app -> main -> res -> values -> styles.xml

Change this line if you want to delete it for every view

 `<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">`

to

 `<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">`

if you want to make it just for one view you can change it in youre manifest data. Go to Android -> manifests -> AndroidManifest.xml. do following:

1. Search the View you want to get this type of change <activity android:name"...">
2. Add android:theme=""@style/Theme.AppCompat.NoActionBar"

Answer 6

I have faced the same problem as you, and solve this problem just by changing the class which I extended.

//you will get the app that does not have a title bar at the top.
import android.app.Activity;
public class MainActivity extends Activity
{}

//you will get the app that has title bar at top
import androidx.appcompat.app.AppCompatActivity;
public class MainActivity extends AppCompatActivity
{}

I hope this will solve your problem.
