Как убрать toolbar android studio
Android Title Bar or ActionBar or Toolbar is the header of any screen in an App. We usually keep fixed title names for every Activity. Sometimes, it is necessary to remove the bar from the activity. There are several ways of doing this. One is if we want to remove the title in all the activities, then we need to go to res > values > themes > theme.xml. and change,
<style name=”Theme.GfgItemSelect” parent=”Theme.MaterialComponents.DayNight.DarkActionBar”>
to
<style name=”Theme.GfgItemSelect” parent=”Theme.MaterialComponents.DayNight.NoActionBar”>
So basically we just need to change DarkActionBar to NoActionBar. NoActionBar theme prevents the app from using the native ActionBar class to provide the app bar. Thus it removes the title of every activity.
Another way for removing the title specifically from an activity is by using a getSupportActionBar().hide() method. Inside the activity’s kotlin file, we need to invoke getSupportActionBar().hide() method.
Android — How to remove the title bar from your application activity
There are three easy ways you can remove the title bar/ action bar from your Android application:
- Setting the <style> tag parent attribute value inside res/styles.xml file
- Hide the action bar from activity class using getSupportActionBar().hide() method
Let’s start by learning how to change the styles.xml file
Remove Android title bar from the main themes file
To remove the title bar/ action bar from your Android application, you can set the <style> tag in your application to NoActionBar .
When you create a new Android application using Android Studio, the <style> tag for your application is commonly generated at Project -> app -> src -> main -> res -> values -> styles.xml or themes.xml depending on your Android Studio version.
The content of the XML file looks similar to this:
You just need to change the action bar from DarkActionBar to NoActionBar at line 4 of the code above:
Additionally, you may also have the values-night folder inside the res folder as shown below:
The values-night folder contains another theme.xml that your Android app will use when the user uses the Dark Theme.
You may also want to set the parent attribute of the <style> tag in this theme.xml to NoActionBar to make your application consistent.
Setting the <style> tag to use NoActionBar will remove the title bar from all activities inside your application.
Remove Android title bar from specific activities
When you want to remove the title bar for one particular activity, you need to hide the title bar from the activity class file.
For example, here’s how you can remove the title bar from your MainActivity class:
Note that getSupportActionBar() is available only when your class extends AppCompatActivity . If you’re extending Activity class, you need to call getActionBar() method instead:
If you’re using Kotlin, then set the call to supportActionBar or actionBar as follows:
And that’s how you can remove the title bar from your Android application ��

How To Remove The ActionBar From Specific Activities (Android Studio)
ActionBar is a special and important part of the android app. It is a menu bar that runs across the top of the activity screen in android. Most beginners don’t have enough idea about it.
You will see an actionbar in every activity when you create an app for the first time. In some activities, we don’t need that. In this article, I am going to show you that how you can remove the actionbar from specific activities and also from all activities.
Remove the ActionBar From Specific Activities
Suppose you are creating an app where you have a splash screen. In that case, we don’t need an actionbar in that splash screen activity. Then you need to remove that actionbar from that specific activity. Here is the step-by-step process to do that.
Step 1: Go to the AndroidManifest.xml file
You can find that by double pressing on the shift key. You can see the file search option in the android studio when you double press on the shift key. Type the file name in the search field and it will show you those files.
Step 2: Find the application tag and activity tag
In the AndroidManifest.xml file, you can see the application tag. Inside the application tag, you can find the activity tag. AndroidManifest.xml file can contain multiple activity tags. It depends on how many activities the developer created during the development process.
Step 3: Find an activity tag for a specific activity
Suppose you have an activity for the splash screen and you want to remove the actionbar for that activity. Check the android:name attributes for each activity tag. If your activity name is MainActivity then the attribute value should be «.MainActivity».
Step 4: Change the theme of the activity
There ate some default themes in Android. You can apply those themes to different activities. In this case, we are going to use «Theme.AppCompat.Light.NoActionBar». This theme is going to remove the actionbar from that activity.
Here is the code that comes default:
Here is the after adding theme:
Here we just added the theme which helps us to make a specific activity actionbar free. Now you can apply this theme to any activity where you don’t want the actionbar. Here is the line of code you have to use in the opening activity tag of an activity.
Remove the ActionBar From All Activities
Most professional app developers don’t like to use the default ActionBar. The recommendation is to use a toolbar instead of ActionBar. The toolbar is easier to use, fully customizable, can be used for all devices. To remove ActionBar from all activities we have to follow the steps below.
Step 1: Go to styles.xml
Using the double press on shift key method you can find out the styles.xml file. You can manually find this option in the android studio toolbar. Click on the search icon (Search Everywhere) and then type the file name in the search box.
Step 2: Change the AppTheme
If you open the styles.xml file you can see some tags. Find the style tag. The default value of the parent attribute is the dark theme. You have to change that to make all activity ActionBar free. Here is the code for no actionbar:
Replace this line with the default theme code. Now your app has no actionbar in it. This is so much important for us to understand the basics of the actionbar. Practice it and try to implement this on different projects.
