[android] Remove Android App Title Bar

I understand that these properties in the manifest:

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

can remove the title bar. However, I constantly check the Graphical Layout when I am modifying my app. When I look at the Graphical Layout I still see the title bar. I want to remove the title bar in a way that I don't have to see it during the development of the game.

This question is related to android layout titlebar

The answer is


Simple way
getSupportActionBar().hide();

Kotlin: supportActionBar?.hide()


Just use this

getSupportActionBar().hide();

In your res/values/styles.xml of modern Android Studio projects (2019/2020) you should be able to change the default parent theme

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

I went one step further and had it look like this

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="android:windowFullscreen">true</item>
</style>

This is based on the code generated from the Microsoft PWA builder https://www.pwabuilder.com/


Title bar in android is called Action bar. So if you want to remove it from any specific activity, go to AndroidManifest.xml and add the theme type. Such as android:theme="@style/Theme.AppCompat.Light.NoActionBar".

Example:

<activity
    android:name=".SplashActivity"
    android:noHistory="true"
    android:theme="@style/Theme.AppCompat.Light.NoActionBar">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
</activity>

In the graphical editor, make sure you have chosen your theme at the top.


If you have import android.support.v7.app.ActionBarActivity; and your class extends ActionBarActivity then use this in your OnCreate:

android.support.v7.app.ActionBar AB=getSupportActionBar();
AB.hide();

If you use AppCompat v7, v21

getSupportActionBar().setDisplayShowTitleEnabled(false);

in the graphical layout, you can choose the theme on the toolbar. (the one that looks like a star).

choose the NoTitleBar and have fun.


Just change the theme in the design view of your activity to NoActionBar like the one here


I was able to do this for Android 2.1 devices and above using an App Compatibility library theme applied to the app element in the manifest:

<application
    ...
    android:theme="@style/AppTheme" />

<style name="AppTheme" parent="@style/Theme.AppCompat.Light.NoActionBar">
    ...
   <item name="windowNoTitle">true</item>
   <item name="android:windowNoTitle">true</item>
</style>

Note: You will need to include the com.android.support:appcompat-v7library in your build.gradle file


for Title Bar

requestWindowFeature(Window.FEATURE_NO_TITLE);

for fullscreen

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);

Place this after

super.onCreate(savedInstanceState);

but before

setContentView(R.layout.xml);

This worked for me.try this


There are two options I'd like to present:

  1. Change the visibility of the SupportActionBar in JAVA code
  2. Choose another Style in your project's style.xml

1: Add getSupportActionBar().hide(); to your onCreate method.

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    getSupportActionBar().hide();
    setContentView(R.layout.activity_main);
}

2: Another option is to change the style of your Application. Check out the styles.xml in "app->res->values" and change

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

Use this to remove title from android app in your Androidmainfest.xml

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

or you can use this in your activity

requestWindowFeature(Window.FEATURE_NO_TITLE); 
setContentView(R.layout.activity_main);

It's obvious, but the App Theme selection in design is just for display a draft during layout edition, is not related to real app looking in cell phone.

Just change the manifest file (AndroidManifest.xml) is not enough because the style need to be predefined is styles.xml. Also is useless change the layout files.

All proposed solution in Java or Kotlin has failed for me. Some of them crash the app. And if one never (like me) uses the title bar in app, the static solution is cleaner.

For me the only solution that works in 2019 (Android Studio 3.4.1) is:

in styles.xml (under app/res/values) add the lines:

   <style name="AppTheme.NoActionBar">
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>
    </style>

After in AndroidManifest.xml (under app/manifests)

Replace

android:theme="@style/AppTheme">

by

android:theme="@style/AppTheme.NoActionBar">

Use this Remove title and image from top.

Before:

setContentView(R.layout.actii);

Write this code:

requestWindowFeature(Window.FEATURE_NO_TITLE);
