Question

I want to hide the titlebar for some of my activities. The problem is that I applied a style to all my activities, therefore I can't simply set the theme to @android:style/Theme.NoTitleBar.

Using the NoTitleBar theme as a parent for my style would remove the title bar from all of my activities.

Can I set a no title style item somewhere?

Solution 3

I now did the following.

I declared a style inheriting everything from my general style and then disabling the titleBar.

<style name="generalnotitle" parent="general">
    <item name="android:windowNoTitle">true</item>
</style>

Now I can set this style to every Activity in which I want to hide the title bar overwriting the application wide style and inheriting all the other style informations, therefor no duplication in the style code.

To apply the style to a particular Activity, open AndroidManifest.xml and add the following attribute to the activity tag;

<activity
    android:theme="@style/generalnotitle">

OTHER TIPS

Do this in your onCreate() method.

//Remove title bar
this.requestWindowFeature(Window.FEATURE_NO_TITLE);

//Remove notification bar
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

//set content view AFTER ABOVE sequence (to avoid crash)
this.setContentView(R.layout.your_layout_name_here);

this refers to the Activity.

You can modify your AndroidManifest.xml:

<activity android:name=".MainActivity"
          android:label="@string/app_name"
          android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen">

or use android:theme="@android:style/Theme.Black.NoTitleBar" if you don't need a fullscreen Activity.

Note: If you've used a 'default' view before, you probably should also change the parent class from AppCompatActivity to Activity.

I don't like the this.requestWindowFeature(Window.FEATURE_NO_TITLE); because the title bar appears briefly, then disappears.

I also don't like the android:theme="@android:style/Theme.NoTitleBar" because I lost all of the 3.0+ Holo changes that the users of the new devices have gotten used to. So I came across this solution.

In your res/values folder make a file called styles.xml (If it doesn't already exist). In that file place the following code:

<resources xmlns:android="http://schemas.android.com/apk/res/android">
    <style name="Theme.Default" parent="@android:style/Theme"></style>
    <style name="Theme.NoTitle" parent="@android:style/Theme.NoTitleBar"></style>
    <style name="Theme.FullScreen" parent="@android:style/Theme.NoTitleBar.Fullscreen"></style>
</resources>

Next create a res/values-v11 with another styles.xml file (Once again this may already exist). In that file place the following code:

<resources xmlns:android="http://schemas.android.com/apk/res/android">
    <style name="Theme.Default" parent="@android:style/Theme.Holo"></style>
    <style name="Theme.NoTitle" parent="@android:style/Theme.Holo.NoActionBar"></style>
    <style name="Theme.FullScreen" parent="@android:style/Theme.Holo.NoActionBar.Fullscreen"></style>
</resources>

And if you are targeting 4.0+, create a res/values-v14 folder with yet another styles.xml file (Yes it may already be there). In that file place the following code:

<resources xmlns:android="http://schemas.android.com/apk/res/android">
    <style name="Theme.Default" parent="@android:style/Theme.Holo.Light"></style>
    <style name="Theme.NoTitle" parent="@android:style/Theme.Holo.Light.NoActionBar"></style>
    <style name="Theme.FullScreen" parent="@android:style/Theme.Holo.Light.NoActionBar.Fullscreen"></style>
</resources>

Finally, with all of these files created, open your AndroidManifiest.xml file you can add the code:

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

to the activity tag of the activity you want no title for or the application tag if you want it to apply to the entire application.

Now your users will get the themes associated with their device version with the screen layout you desire.

P.S. Changing the value to android:theme="@style/Theme.FullScreen" will have the same effect, but also remove Notification bar.

The title bar can be removed in two ways as mentioned on the developer Android page:

In the manifest.xml file:

Add the following in application if you want to remove it for all the activities in an app:
```
<application android:theme="@android:style/Theme.Black.NoTitleBar">
```

Or for a particular activity:

<activity android:theme="@android:style/Theme.Black.NoTitleBar">

the correct answer probably is to not extend ActionbarActivity rather extend just Activity

if you still use actionbar activity seems this is working:

@Override
protected void onCreate(Bundle savedInstanceState) {          
    super.onCreate(savedInstanceState);
    getSupportActionBar().hide(); //<< this
    setContentView(R.layout.activity_main);
}

seems this works too:

styles.xml:

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

i could do like as Scott Biggs wrote. this kind of works. except there is no theme then. i mean the settings menu's background is transparent:

just change

public class MainActivity extends ActionBarActivity {

to Activity or FragmentActivity

public class MainActivity extends Activity  {

however i could make it look good enough using material design and not remove the actionbar: https://gist.github.com/shimondoodkin/86e56b3351b704a05e53

set icon of application
set colors of action bar to match design.
set icon to settings menu
add more icons (buttons on top)

it is by example of material design compatibility actionbar styling.

If you use this.requestWindowFeature(Window.FEATURE_NO_TITLE) user will still be able to see the title bar just for a moment during launch animation when activity starts through onCreate. If you use @android:style/Theme.Black.NoTitleBar as shown below then title bar won't be shown during launch animation.

<activity 
    android:name=".MainActivity" 
    android:label="My App"
    android:theme="@android:style/Theme.Black.NoTitleBar"
    android:screenOrientation="portrait">

above example will obviously override your existing application theme, if you have existing theme then add <item name="android:windowNoTitle">true</item> to it.

what works for me:

1- in styles.xml:

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

2- in MainActivity

@Override
protected void onCreate(Bundle savedInstanceState) {          
    super.onCreate(savedInstanceState);
    getSupportActionBar().hide(); //<< this
    setContentView(R.layout.activity_main);
}

in manifest inherit the style:

<activity android:name=".MainActivity" android:theme="@style/generalnotitle">

when i tried to use all those high upvoted answers my app always crashed. (i think it has something to do with the "@android:style"?)

The best solution for me was to use the following:

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

No header / title bar anymore. Just place it in the <application>...</application> or <activity>...</activity> depending if you (don't) want it in the whole app or just a specific activity.

Create a theme as below.

 <!-- Variation on the Light theme that turns off the title -->
<style name="MyTheme" parent="android:style/Theme.Black">
    <item name="android:windowNoTitle">true</item>
</style>

Add

<item name="android:windowNoTitle">true</item>

inside AppTheme (styles.xml)

Just use getActionBar().hide(); in your main activity onCreate() method.

You just need to change AppTheme style in Style.xml if you replace the definition from DarkActionBar

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

to NoActionBar

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

the AppTheme defined in AndroidManifast.xml

For AppCompat, following solution worked for me:

Add new theme style with no action bar in your styles.xml and set parent="Theme.AppCompat.NoActionBar".

<style name="SplashTheme" parent="Theme.AppCompat.NoActionBar">

    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimary</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="android:windowBackground">@color/colorPrimary</item>

</style>

Now implement the same theme style to your splash screen activity in androidManifest.xml

<activity
        android:name=".ActivityName"
        android:theme="@style/SplashTheme"> // apply splash them here 

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

Here is result:

You can use this code in your java file

add this line before you set or load your view

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

In your onCreate method, use the following snippet:

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

Add both of those for the theme you use:

    <item name="windowActionBar">false</item>
    <item name="android:windowNoTitle">true</item>

Add this style to your style.xml file

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

After that reference this style name into your androidManifest.xml in perticular activity in which you don't want to see titlebar, as like below.

<activity android:name=".youractivityname"
     android:theme="@style/AppTheme.NoActionBar">
</activity>

Or if you want to hide/show the title bar at any point:

private void toggleFullscreen(boolean fullscreen)
{
    WindowManager.LayoutParams attrs = getWindow().getAttributes();
    if (fullscreen)
    {
        attrs.flags |= WindowManager.LayoutParams.FLAG_FULLSCREEN;
    }
    else
    {
        attrs.flags &= ~WindowManager.LayoutParams.FLAG_FULLSCREEN;
    }
    getWindow().setAttributes(attrs);
}

I'm using a support widget Toolbar v7. So, in order to be able to delete or hide the Title we need to write this.

Toolbar myToolbar = (Toolbar) findViewById(R.id.my_toolbar);
setSupportActionBar(myToolbar);

//Remove¡ing title bar
getSupportActionBar().setDisplayShowTitleEnabled(false);

In my case, if you are using android studio 2.1, and your compile SDK version is 6.0, then just go to your manifest.xml file, and change the following code:

Here is the code:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.lesterxu.testapp2">

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/Theme.AppCompat.NoActionBar">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

</manifest>

And here is the snip shoot(see the highlight code):

This Solved my problem

In manifest my activity:

<application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".SplashScreen">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

In style under "AppTheme" name:

<resources>

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

</resources>

To Hide both Title and Action bar I did this:

In activity tag of Manifest:

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

In Activity.java before setContentView:

this.requestWindowFeature(Window.FEATURE_NO_TITLE);
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

i.e.,

//Remove title bar

this.requestWindowFeature(Window.FEATURE_NO_TITLE);

//Remove notification bar

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

NOTE: You need to keep these lines before setContentView

First answer is amphibole. here is my explain: add:

this.requestWindowFeature(Window.FEATURE_NO_TITLE);
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);

in oncreate() method.

before:

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_start);

(not just before setContentView) if don't do this u will get forceclose. +1 this answer.

I found two reasons why this error might occur.

One. The Window flags are set already set inside super.onCreate(savedInstanceState); in which case you may want to use the following order of commands:

this.requestWindowFeature(Window.FEATURE_NO_TITLE);
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);      

super.onCreate(savedInstanceState);

Two. You have the Back/Up button inside the TitleBar, meaning that the current activity is a hierarchical child of another activity, in which case you might want to comment out or remove this line of code from inside the onCreate method.

getActionBar().setDisplayHomeAsUpEnabled(true);

This is how the complete code looks like. Note the import of android.view.Window.

package com.hoshan.tarik.test;

import android.app.Activity;
import android.os.Bundle;
import android.view.Window;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.activity_main);
    }
}

Add theme @style/Theme.AppCompat.Light.NoActionBar in your activity on AndroidManifest.xml like this

<activity
        android:name=".activities.MainActivity"
        android:theme="@style/Theme.AppCompat.Light.NoActionBar">
    </activity>

If you do what users YaW and Doug Paul say, then you have to have in mind that window features must be set prior to calling setContentView. If not, you will get an exception.

add in manifiest file ,

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

add following line into ur java file,

  this.requestWindowFeature(Window.FEATURE_NO_TITLE);

Ahem, you can apply themes to individual activities in XML such as no title. In other words, take it out of your application tag, open the tag declaration and put it in the desired activity tag.
