How to create Android application without ActionBar using new theme in API9? - android

I need to create application wihtout actionbar. I will try to explain how I create application(maybe I am missing some steps).
1.I am intentionally not choosing "Holo Light with Dark Action Bar" option. I thought this make application without action bar.
2.Leaving next page as default:
3.Leaving next page as default:
4.On the next page, it becomes interesting. Blank Activity's description says that it creates a new blank activity an action bar. On Empty Activity's description: Creates a new empty activity. So I choose Empty activity
5.Leaving next page as default.
Result:As usually, application was created with ActionBar.
Tried this solution:getActionBar().hide();. In this solution, ActionBar is hiden after some milliseconds.
Tried to use android:theme="#android:style/Theme.NoTitleBar" in AndroidManifest.xml->application tag. But in this solution, application uses old theme.
My question: how to create Android application without ActionBar using new theme and leaving StatusBar enabled?
PS. I remember, about one year ago, in Eclipse, applications were created without ActionBar. Then we added it manually

Put this right after super.onCreate(savedInstanceState); in the onCreate method of your activity(s):
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
Make sure you put this BEFORE this.setContentView(R.layout.activity_example); to avoid crashes

When your project is started you can use public activity extends Activity instead of using ActionBarActivity this will also remove the action bar or there is another way
<android:theme="#android:style/Theme.NoTitleBar">
or you can see these links they might help
How to hide action bar before activity is created, and then show it again?
Remove android default action bar

Refer this code and change as per your requirement:
Update :
styles.xml :
<style name="FullscreenTheme" parent="android:Theme.Holo">
<item name="android:windowActionBar">false</item>
<item name="android:windowNoTitle">true</item>
<item name="android:actionBarStyle">#style/FullscreenActionBarStyle</item>
<item name="android:windowActionBarOverlay">true</item>
<item name="android:windowBackground">#null</item>
<item name="metaButtonBarStyle">?android:attr/buttonBarStyle</item>
<item name="metaButtonBarButtonStyle">?android:attr/buttonBarButtonStyle</item>
</style>
<style name="FullscreenActionBarStyle" parent="android:Widget.Holo.ActionBar">
<item name="android:background">#color/black_overlay</item>
</style>
These will remove actionbar and keeps your theme as it is .
Note : Here i have tested using Theme.Holo . you can use yours.
AndroidManifest.xml
<activity
android:name=".GridViewExample"
android:theme="#style/FullscreenTheme" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
It gives you activity without ActionBar.
Hope this solves your problem.

You can do it programatically:
public class ActivityName extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// remove title
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.main);
}
}
Or you can do it via your AndroidManifest.xml file:
<activity android:name=".ActivityName"
android:label="#string/app_name"
android:theme="#android:style/Theme.NoTitleBar.Fullscreen"/>
EDIT :
If your app uses any other theme use corresponding theme name E.g. For White theme #android:style/Theme.Holo.Light.NoActionBar.Fullscreen

How to disable the title on the ActionBar in Main Launcher Activity

I checked this issue, couldn't find an answer.
there are 3 places I checked that show the label on 3 separated places in my android phone or app.
Under the logo of the app
In the app processes which show's the active apps, (from that window you can close the app process)
In the most annoying place, the "splash" action bar title (It happens before the MAIN activity UI start, when it loading the activity onCreate I believe), which most of us want to get rid of usually.
The 3 places are:
<application
android:name=".Application"
android:icon="#mipmap/icon"
android:label="#string/app_name" <!-- 1--- the first place-->
android:theme="#style/AppTheme">
<activity
android:name=".LoadingActivity"
android:label="#string/app_name" <!-- 2--- the second place-->
android:theme="#style/AppTheme.NoActionBar">
<intent-filter android:label="#string/app_name"> <!-- 3--- the third place-->
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
I checked on my phone (LG4 - android 5.1).
I saw that place 2 print on the action bar and the process but place 3 print on under the app icon in the phone.
BUT! when I checked in another phone (Hawaii P9 - android 6.0)
I saw place 2 printed under the app icon in the phone, unlike in LG4 which was place 3 who did this.
The main reason I actually checked it, is that I don't want the title to appear in the action bar, while I want it to appear under the app icon and in the processes.
Any help from an expert?
sorry for commenting in the answer section but that's cuz of the low reputation, will you add your onCreate method code in order to tell you how to use
.setTitle(" ");
in which you set the title blank to make the app name doesn't appear if that helps you
1) You could override the action bar , to use your custom action bar layout.
getSupportActionBar.setCustomView("your custom view");
2) If you just want to hide the title , you could set the title using
getSupportActionBar.setTitle("");
getSupportActionBar.setSubtitle("");
if (getSupportActionBar() != null) {
getSupportActionBar().setTitle("");
}
if (getSupportActionBar() != null) {
getSupportActionBar().setDisplayShowTitleEnabled(false);
}
From the answers you gave me, I figure a way to do what I need in a way.
I changed the main launcher activity to extend from AppCompatActivity instead of Activity, that way I could use your suggerstions you listed.
(Although I still wonder how to do it with the regular Activity)
The style themes was also enough for me, and it worked in a neater way!
<style name="MyActionBar" parent="#android:style/Widget.Holo.Light.ActionBar">
<item name="android:background">#color/colorPrimaryDark</item>
<item name="background">#color/colorPrimaryDark</item>
</style>
<style name="MyAppTheme.NoActionBar" parent="Theme.AppCompat.NoActionBar">
<item name="colorPrimary">#color/colorPrimaryDark</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="android:statusBarColor">#color/colorPrimaryDark</item>
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
<item name="android:windowBackground">#color/colorPrimaryDark</item>
<item name="android:actionBarItemBackground">#color/colorPrimaryDark</item>
<item name="android:actionBarStyle">#style/MyActionBar</item>
</style>
This xml style, fix the selected PrimaryColor in all of the wanted places and won't show the title in the main launch activity loading actionbar, while showing it under the icon and in the processes!

Android - Disable dummy starting window of application

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.

How to Make my Android App FullScreen via Android Manifest?

How do I do this? Any suggestions? BTW I am using SDK with AIDE.
Go into the manifest and use a full screen theme.
<activity
android:name=".Foo"
android:label="#string/foo"
android:theme="#android:style/Theme.NoTitleBar.Fullscreen">
This code makes the current Activity Full-Screen. No Status-Bar or anything except the Activity-Window!
public class FullScreen extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.main);
}
}
Edit for AppCompactActivity
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/orange</item>
<item name="colorPrimaryDark">#android:color/holo_orange_dark</item>
<item name="android:windowNoTitle">true</item>
<item name="android:windowFullscreen">true</item>
</style>
If you want a full screen put this attribute in <activity /> or <application /> tag in your Manifest file
android:theme="#android:style/Theme.NoTitleBar.Fullscreen"
Agree with the above answer given by SquiresSquire. Just adding little more information in the answer i would like to present my answer.
You can make your application full screen in two ways,
Making Full Screen any particular Activity
add theme element in activity tag
<activity
android:name=".YourActivityName"
android:theme="#android:style/Theme.NoTitleBar.">
Making Full Screen whole application
add theme element with application tag
<application
android:icon="#drawable/icon"
android:theme="#android:style/Theme.NoTitleBar.">
To set your Application or any individual activity display in Full Screen mode,
Insert the code in AndroidManifest .xml file
#android:style /Theme. NoTitle Bar.Fullscreen
This works well for me.
android:theme="#style/Theme.AppCompat.NoActionBar"

Programmatically turn off android:windowActionBarOverlay style from action bar

Currently, I am using ActionBarSherlock. I want to launch SecondActivity from MainActivity.
MainActivity is using action bar with windowActionBarOverlay style turned on. SecondActivity is using action bar with windowActionBarOverlay style turned off. Hence, here is how my XML looks like.
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:debuggable="false" >
<activity
android:name=".MainActivity"
android:label="#string/app_name"
android:theme="#style/ThemeWithActionBarOverlay"
android:screenOrientation="nosensor" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".SecondActivity"
android:theme="#style/ThemeWithoutOverlay">
</activity>
</application>
<resources>
<style name="ThemeWithActionBarOverlay" parent="#style/Theme.Sherlock">
<item name="android:windowActionBarOverlay">true</item>
<item name="abIcon">#drawable/ic_home</item>
<item name="abTitleTextStyle">#style/ActionBarCompatTitle</item>
</style>
<style name="ThemeWithoutOverlay" parent="#style/Theme.Sherlock">
<item name="abIcon">#drawable/ic_home</item>
<item name="abTitleTextStyle">#style/ActionBarCompatTitle</item>
</style>
</resources>
However, by doing so, in SecondActivity, I realize I can never have a up/back button on the top left of action bar. Although there is icon being shown, it is not pressable. Only by using back same theme (ThemeWithActionBarOverlay) as MainActivity, only up/back button will shown. However, if I let SecondActivity to use same theme as MainActivity, I find out no way to turn off windowActionBarOverlay behaviour.
// SecondActivity
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.history_list_activity);
ActionBar actionBar = this.getActionBar();
actionBar.setDisplayHomeAsUpEnabled(true);
// How to turn android:windowActionBarOverlay attribute to false during runtime?
// actionBar.???
}
My questions are
Why the child activity has to use action bar with same theme as parent's, in order to have proper up/back button shown? Is there any way I can use different themes, yet have up/back button appears on child activity?
Is it possible to turn of windowActionBarOverlay style during runtime?
To answer your first question, you don't need to have the parent and child activity using the same theme for the 'Up' button to work. In fact, I'm working on a similar parent/child activity application, and its working just fine using two different themes( a theme without overlay for the parent, and the fullscreen theme (with overlay) for the child).
There must be another reason why it is not working...
Make sure you have defined MainActivity to be the parent of second activity. You can do that either by code, or the prefered way, in the AndroidManifest.xml:
<activity
android:name=".SecondActivity"
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value=".MainActivity" />
</activity>
Make sure that in your child activity, you have activated the 'up' navigation:
final ActionBar actionBar = getSupportActionBar();
actionBar.setDisplayHomeAsUpEnabled(true);
For your second question, try overriding the 'windowActionBarOverlay' in the 'ThemeWithoutOverlay' theme to false:
<style name="ThemeWithoutOverlay" parent="#style/Theme.Sherlock">
<item name="android:windowActionBarOverlay">false</item>
<item name="windowActionBarOverlay">false</item><
<item name="abIcon">#drawable/ic_home</item>
<item name="abTitleTextStyle">#style/ActionBarCompatTitle</item>
</style>

Hiding Dialog's titlebar in Android Manifest

Basically, I created an Activity inside a dialog, everthing is seems working perfectly but the problem is the title bar of a dialog is still there. Is there anyway to hide it?
And also this is the tutorial, here is the link. It is exactly what I am trying to accomplish except witout title bar.
Note: THIS IS NOT JUST AN ALERTDIALOG OR DIALOG, THIS IS AN ACTIVITY INSIDE A DIALOG which only became looks like a dialog by pasting the code below.
<activity android:label="My Dialog (activity)" android:name=".MyActivity" android:theme="#android:style/Theme.Dialog"></activity>
If ur using appcompat support v4, v7 libraries then try using
supportRequestWindowFeature(Window.FEATURE_NO_TITLE);
before setContentView and also before super.Oncreate();
You can remove the title bar programatically.
Add this line to your Activity onCreate() method.
requestWindowFeature(Window.FEATURE_NO_TITLE);
Edit:
Create a custom style that extend Theme.Dialog:
<resources>
<style name="NoTitleDialog" parent="android:Theme.Dialog">
<item name="android:windowNoTitle">true</item>
</style>`
</resources>
Then reference this theme in your activity android:theme attribute. :)
I came up with such, easiest solution:
In Manifest
android:theme="#android:style/Theme.Holo.Light.Dialog.NoActionBar">
Seems to work.
Try this :
style.xml
<style name="NoTitleActivityDialog" parent="Theme.AppCompat.Light.Dialog.Alert">
<item name="windowNoTitle">true</item>
</style>
AndroidManifest.xml
<activity
android:name=".DialogActivity"
android:theme="#style/NoTitleActivityDialog"/>
