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>

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!
I'm new in the Android programming world, and I don't understand why the system is not displaying the application icon on the left side of the 'ActionBar' of my first Android application (HelloWorld).
In the 'ActionBar' developer guide it's stated that:
"By default, the system uses your application icon in the action bar, as specified by the icon attribute in the "application" or "activity" element. However, if you also specify the logo attribute, then the action bar uses the logo image instead of the icon."
(Action bar)
My Android-manifest file isn't defining a 'logo' attribute, but it defines just an 'icon' attribute. Therefore, the icon defined by the 'icon' attribute should be displayed on the left side of the 'ActionBar' as the application icon. However, no icon is being displayed.
My Android-manifest file is as follows:
<?xml version="1.0" encoding="utf-8"?>
<manifest
xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.holamundo"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="21" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppBaseTheme">
<activity
android:name=".MainActivity"
android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
And my style files are the following:
/res/values/styles.xml:
<resources>
<style name="AppBaseTheme" parent="Theme.AppCompat.Light">
</style>
<style name="AppTheme" parent="AppBaseTheme">
</style>
</resources>
/res/values-v11/styles.xml:
<resources>
<style name="AppBaseTheme" parent="Theme.AppCompat.Light">
</style>
</resources>
/res/values-v14/styles.xml:
<resources>
<style name="AppBaseTheme" parent="Theme.AppCompat.Light.DarkActionBar">
</style>
</resources>
Can anyone explain me why my application icon is not being displayed in the ActionBar and what should I modify in order to such an icon be displayed? Thanks.
Your activity must extend ActionBarActivity.
For example:
public class MainActivity extends ActionBarActivity
{
...
}
Or try this in your activity:
ActionBar actionBar = getActionBar();
actionBar.setHomeButtonEnabled(true);
actionBar.setDisplayOptions(ActionBar.DISPLAY_SHOW_HOME | ActionBar.DISPLAY_SHOW_TITLE);
actionBar.setIcon(R.drawable.ic_launcher);
You will have to use getSupportActionBar() if using the support library.
I've also been having the problem where a menu item icon is not being displayed. I have a toolbar and I set it up to be the support action bar. The manifest declares a NoActionBar theme. Originally I thought that none of the icons for action items would display, however, I've discovered that some drawable icons would display. For, example "#android:drawable/ic_menu_add" would work, but "drawable/ic_launcher_background" would not work. Here's the menu structure that I inflate during the onCreateOptionsMenu. The item action_logo uses a png file and that one works too. The 'ic_launcher_background" is a drawable that is automagically added when the project was created.
<item
android:id="#+id/action_help"
android:orderInCategory="50"
android:title="#string/action_help"
android:icon="#android:drawable/ic_menu_add"
app:showAsAction="always" />
<item
android:id="#+id/action_more"
android:orderInCategory="60"
android:title="#string/action_help"
android:icon="#drawable/ic_launcher_background"
app:showAsAction="always" />
<item
android:id="#+id/action_logo"
android:orderInCategory="70"
android:title="#string/action_help"
android:icon="#drawable/tabellae_logo"
app:showAsAction="always" />
<item
android:id="#+id/action_settings"
android:orderInCategory="100"
android:title="#string/action_settings"
app:showAsAction="never" />
What I've been trying to do was to generate a BitmapDrawable on the fly an add it to the menu during a onPrepareOptionsMenu call, but that kind of drawable won't display either.
I have different test application that has it's manifest set to an ActionBarTheme. In this configuration, you don't need to call setSupportActionBar. (It's error if you try to do so) Now this test application displays all the menu icons correctly. It is an AppCompatActivity application. My guess is that this test application is probably using the old style ActionBar rather then the newly recommended ToolBar approach and that's why it works.
My preference is to use the ToolBar approach, but I don't have an explanation why some icon drawables work and other do not. In my research on this problem, I've not seen anyone mention these observations. Perhaps someone would have more insight into why certain drawables don't work for menu item icons.
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
I am having problems trying to remove the Activity title text from my Action Bar Sherlock.
I have spent(wasted) a lot of time trying to find a solution and just cannot make this work.
I have a Splash Activity on which I go full screen. But just before the Splash Activity appears, a screen appears (for a very short period of time) that has nothing but an Action Bar with the App Icon and Activity Title Text. I do not understand why it appears. Is this default Android behavior? I want to avoid this screen, or at least remove the Activity Title from the Action Bar on this screen. If I set it to "", I lose the app from the Recent Apps chooser.
Please refer to these images:
Pre Splash :

I have referred to the following examples on SO and also searched elsewhere. But nothing seems to work.

How do you remove the title text from the Android ActionBar?
How can I remove title and icon completetly in Actionbar sherlock?
Please check my Android Manifest and the theme file...
<application
android:name="com.zipcash.zipcashbetaversion.MyApplication"
android:allowBackup="true"
android:icon="#drawable/zipcash_icon"
android:label="#string/app_name"

And so on...
The following is my theme file:

<!-- Set style for Action Bar (affects tab bar too) -->
<item name="actionBarStyle">#style/Widget.MyTheme.ActionBar</item>
</style>
<style name="Widget.MyTheme.ActionBar" parent="Widget.Sherlock.ActionBar">
<!-- define background for action bar (sets default for all parts of action bar - main, stacked, split) -->

<item name="android:textSize">0sp</item>
<item name="android:textColor">#00000000</item>
<item name="android:visibility">invisible</item>
</style>
I have also written this code in my Splash Activity:
ActionBar actionBar = getSupportActionBar();
actionBar.setDisplayOptions(actionBar.getDisplayOptions() ^ ActionBar.DISPLAY_SHOW_TITLE);
actionBar.hide();
ActivityHelper.initialize(this);
setContentView(R.layout.activity_splash);
Have I made a mistake that I am overlooking. Is there something else I should do. My minimum API level is 8.
Any help will be appreciated.
You can add this to your activity:
android:theme="#android:style/Theme.Black.NoTitleBar.Fullscreen" >
When you first launch your app and Application onCreate haven't finished loading you see the empty lag screen. You can set the window background to green and remove the ActionBar for Application theme, so it will look splash-like.
colors.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="splash_background">#86bf3a</color>
</resources>
styles.xml
<style android:name="SplashTheme" parent="#style/Theme.Sherlock.Light.NoActionBar">
<item name="android:windowBackground">#color/splash_background</item>
</style>
Make application use splash theme with green background and no ActionBar
<application
...
android:theme="#style/SplashTheme" >
<activity

</activity>
<!--...
make all other Activities use MyTheme
...-->
<activity
android:name="com.zipcash.zipcashbetaversion.SignUpActivity"
...
android:theme="#style/Theme.MyTheme" />
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()}
