Remove Android App Title Bar

Question

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.

Answer 1

1. In the Design Tab, click on the AppTheme Button

2. Choose the option "AppCompat.Light.NoActionBar"

3. Click OK.

Answer 2

Simple way
getSupportActionBar().hide();

Answer 3

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

Answer 4

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

Answer 5

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);

Answer 6

If you use AppCompat v7, v21

getSupportActionBar().setDisplayShowTitleEnabled(false);

Answer 7

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>

Answer 8

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

Answer 9

Just use this

getSupportActionBar().hide();

Answer 10

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();

Answer 11

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.

Answer 12

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

Answer 13

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">

Answer 14

Use this Remove title and image from top.

Before `

setContentView(R.layout.actii);

`

Write this code and Execute

requestWindowFeature(Window.FEATURE_NO_TITLE);
