I am using following code to replace title bar.
final boolean customTitleSupported = requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.main);
And it's working fine once UI loaded. Problem is however when I start the app, the ugly gray bar appears for 1-2 seconds until UI loaded. Is there any way to specify not showing the default title bar at all?
If you want the titlebar to be gone in every activity within your app, then add
<application android:name=".YourAppNameHere"
android:label="#string/app_name"
android:icon="#drawable/icon"
android:theme="#android:style/Theme.NoTitleBar">
to your manifest. Not 100% sure though that this will prevent the titlebar from showing up momentarily, but it should work.
In the Manifest file, add this line inside the application tag
android:theme="#android:style/Theme.NoTitleBar"
It will hide the bar from all the activities. If you want to hide it from a specific activity, add the same line to that activity's tag.
Good Luck !
You should add a line to your AndroidManifest which states that you use a theme (standard android or extended)
<application android:name=".YourAppNameHere"
android:label="#string/app_name"
android:icon="#drawable/icon"
android:theme="#style/MyTheme">
and then you can have a themes.xml in your res/values/ folder where you extend the: Theme.NoTitleBar and add custom rules to them (for example like windowBackground)
<resources>
<style name="MyTheme" parent="android:Theme.NoTitleBar">
<item name="android:windowBackground">#drawable/my_background</item>
</style>
<resources>
Have fun

I've been having a very hard time trying to get rid of the Title Bar on the application I'm developing. I'm using Android Studio.
I've tried almost all the methods that have been listed on various places on the net..
super.onCreate()...
this.requestWindowFeature(Window.FEATURE_NO_TITLE); // also used it without the "this"
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
this.setContentView(R.layout.your_layout_name_here);
in the .java file
also tried a couple of other methods in the .java file
I've tried changing the codes in the manifest file as well using
<activity android:name=".MainActivity"
android:label="#string/app_name"
android:theme="#android:style/Theme.NoTitleBar.Fullscreen">
even by changing the theme under the Application tag..
I've tried changing the style tag in the styles.xml to something like
<style name="AppTheme">
<item name="android:windowNoTitle">true</item>
<item name="android:windowFullscreen">true</item>
but all of these have failed. The app has CRASHED in all of the above instances. Any help will be deeply appreciated.
try this before your setContentView(..)
Window window = getWindow();
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
if (Build.VERSION.SDK_INT > 20)
window.setStatusBarColor(getResources().getColor(R.color.color_white));
or if your ok with it. #android:style/Theme.Holo.NoActionBar though i prefer not using this.
or if youre using appCompat libs
1.Go to your manifest.xml file.
2.Find the activity tag for which you want to hide your ActionBar and then add,
android:theme="#style/Theme.AppCompat.NoActionBar"
<activity android:name=".MainActivity" android:theme="#style/Theme.AppCompat.NoActionBar">
I think you are extending either actionbaractivity or appcompatactivity .Instead of them simply extend Activity and then use
requestWindowFeature(Window.FEATURE_NO_TITLE);
Can someone explain what is happening here. I load a blank Activity and two xml files are created in Android Studio; the content_main.xml, which contains all of my widgets, and activity_main.xml, which includes my contents file and looks like this:
I don't want to use this Toolbar so I delete it. Now the activity_main.xml file looks like this:
I still want to have an actionBar however. My manifest file, clearly references a theme in my styles folder:
And here is is the styles.xml file, which sets a theme for the Action Bar:
How come, when I start the emulator, my action bar is missing? My main_activity extends AppCompatActivity. Any idea why this is happening?
you are activity is overriding the Application's theme and using the NoActionBar theme. Get rid of android:theme from the <activity tag
Change from
<activity
android:theme="#style/AppTheme.NoActionBar"
android:name=".MainActivity"
android:label="#string/app_name">
to
<activity
android:name=".MainActivity"
android:label="#string/app_name">
I want to know how to achieve this effect.
My app (default everything), when launcher icon is clicked, right away display some kind of a empty dummy window, where nothing is happening and then loads layout into it.
"Heavier" apps like YouTube, Drive, Dropbox etc. when started, seem to wait after launch, without showing that dummy window and load right into ready layout.
Any idea how to do this or where should I look into?
Thanks
//EDIT: this has nothing to do with something like loading database, where I should display progressBar, imho this has to do with stuff before activity exists.
I suggest you don't disable the dummy loading window using:
<style name="Theme.MyTheme" parent="android:style/Theme" >
....
<item name="android:windowDisablePreview">true</item>
....
</style>
because you could run into several problems. For example, if you try to animate an AlertDialog, enter animation will not work (personal experience).
The right solution is to set the theme of your application like to your main activity screen (same ActionBar style, same background color).
In my application after severals experiments i found the right solution for my needs.
(I have a main activity with blank background, no ActionBar, just full screen personal layout)
1 - styles.xml: add new style like this (remove ActionBar and set the same background color of my main activity)
<style name="LoadingTheme" parent="#android:style/Theme.Light.NoTitleBar.Fullscreen">
<item name="android:windowBackground">#color/white_smoke</item>
</style>
2 - AndroidManifest.xml: set my theme for main activity to "LoadingTheme"
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="com.company.appname.MainActivity"
android:label="#string/app_name"
android:theme="#style/LoadingTheme">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
....
</application>
And finally i have full blank dummy loading window without ActionBar with soft MainActivity load and working animations.
Hope to be helpful.
<style name="Theme.MyTheme" parent="android:style/Theme" >
....
<item name="android:windowDisablePreview">true</item>
....
</style>
but use with caution
This will create a custom preview window for your activity.
Create a style in styles.xml like
<style name="MyTheme" parent="#android:style/Theme.Holo.NoActionBar">
<item name="android:windowBackground">#color/myBackgroundColor</item>
</style>
In your Manifest file use the theme created above.
For eg:
<activity android:name=".MyActivity"
android:label="#string/app_name"
android:theme="#style/MyTheme"
/>
In your activity change the background of the window back to null in onCreate()
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().setBackgroundDrawable(null);
setContentView(R.layout.main);
}
You can call the setContentView method anywhere you'd like in your activity. Before calling this method it will display a blank screen. If you wanted a splash screen, you can call the setContentView method within the onCreate method to display the splash screen view. Then when you're ready to display the "main" view you can use a LayoutInflater to display it. I also suggest using a ProgressDialog to show the user that information is loading.
Load your resources before setting the contentview. There will be a dummy window until you would not set view using setContentView.
EDIT
To avoid this screen. Make there changes to your code.
1) Do not do any heavy work in activity onCreate method. Run a separate thread for it.
2) Set content view right after the super.onCreate() line
super.onCreate(savedInstanceState);
setContentView (R.layout.splash_screen);
3) Apply following theme to your application.
Define theme in style
<resources>
<style name="Theme.MyTheme" parent="android:style/Theme" >
<item name="android:windowNoTitle">true</item>
<item name="android:windowContentOverlay">#null</item>
<item name="android:windowBackground">#drawable/any_default_background</item>
</style>
</resources>
In your Manifest
<application
....
android:theme="#style/Theme.MyTheme"
....
>
Thats It.
When I created new Android application in Eclipse.In its AndroidManifest.xml the theme set to application isandroid:theme="#style/AppTheme"& style.xml is as follows.
<resources>
<style name="AppTheme" parent="android:Theme.Light" />
</resources>
& my screen appears like this.
I want to remove the TitleBar from app but want to show the theme of Android 4.1's.
For this I tried
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#android:style/Theme.Light.NoTitleBar" >
Now my screen appears like this the TitleBar is removed but theme has changed.
Please help me to sort out this issue.
Use this instead : #android:style/Theme.Holo.NoActionBar.
Try out putting this in your manifest.
android:theme="#android:style/Theme.NoTitleBar.Fullscreen"
My goal is to show a splash screen on my applications startup. Right now what it will do is briefly show the actionbar with an otherwise blank page, then jump to the splash screen. I'm trying to figure out how to not show the beginning screen and just start with the splash screen.
I'm trying to use these links for information on how to solve this.
ActionBar Lag in hiding title
In this one I'm assuming I can use the same type of method for hiding the actionbar by changing the theme, but I don't know what I would actually use as my style to do so.
How to hide action bar before activity is created, and then show it again?
and here it talks about adding a line to the manifest that would do it. Where in the manifest? Anywhere I put it did not do anything.
try this in manifest file
<activity
android:name="yourActivityName"
android:label="your label"
android:theme="#android:style/Theme.Holo.Light.NoActionBar.Fullscreen" >
</activity>
Check this link Android: hide action bar while view load
Code snippets from the link, incase the link breaks down, courtesy #kleopatra:
Setting the properties windowNoTitle to true on your theme will
hide the ActionBar. use two different themes both extending parent="Theme.AppCompat.Light" in order to prevent NPE when using getSupportActionBar
set the styles as
<style name="AppThemeNoBar" parent="Theme.AppCompat.Light">
<item name="android:windowNoTitle">true</item>
</style>
<style name="AppThemeBar" parent="Theme.AppCompat.Light">
<item name="android:windowNoTitle">false</item>
</style>
Due to some odd behaviour on versions < 11, you need to add
if (Build.VERSION.SDK_INT < 11){
getSupportActionBar().hide(); }
inside activities that do not need the actionbar
Delete the "android:label" entries in Manifest file, from application and the first activity which is loaded. In your case, the Splash activity.
Sample...
<application
android:allowBackup="true"
android:icon="#drawable/starticon"
android:label="#string/app_name"
android:theme="#android:style/Theme.Holo">
<activity
android:name=".ActivitySplash"
android:label="#string/app_name"
>
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
Just add this code in your Activity in the onCreate function.
val actionBar = supportActionBar?.apply{hide()}
