I've developed a simple demo application with a splash screen a map and some regular screens.
I have an action bar at the top that contains a logo. It all looks fine on my phone (Galaxy s1 I9000 V2.3) but when i test it on Galaxy s2 v4 the action bar appears also in the splash screen and in the map screen.
The spalsh and map activity are not even inheriting from ActionBarActivity so how is that possible and how can i make it go away?
Manifest:
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:theme="#style/Theme.AppCompat.Light" >
<activity
android:name=".HomeActivity"
android:icon="#drawable/android_logo"
android:label=""
android:logo="#drawable/android_logo" >
<!--
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
-->
</activity>
<activity
android:name=".MapActivity"
android:label="" >
</activity>
<activity
android:name=".PackageActivity"
android:icon="#drawable/android_logo"
android:label=""
android:logo="#drawable/android_logo" >
</activity>
<activity
android:name=".SplashActivity"
android:label="" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
MapActivity definition (it's a long one so i included just the definition):
public class MapActivity extends FragmentActivity implements LocationListener
Splash Activity:
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.os.Handler;
import android.support.v7.app.ActionBar;
import android.support.v7.app.ActionBarActivity;
public class SplashActivity extends Activity{
private static final long SPLASH_DISPLAY_LENGTH = 2000;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash);
new Handler().postDelayed(new Runnable(){
#Override
public void run() {
Intent mainIntent = new Intent(SplashActivity.this,HomeActivity.class);
SplashActivity.this.startActivity(mainIntent);
SplashActivity.this.finish();
}
}, SPLASH_DISPLAY_LENGTH);
}
}
As you are asking about how to hide in a certain activity, this is what you need :
getSupportActionBar().hide();
Apply the following in your Theme for the Activity in AndroidManifest.xml:
<activity android:name=".Activity"
android:label="#string/app_name"
android:theme="#android:style/Theme.NoTitleBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
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"
>
If you want to get full screen without actionBar and Title.
Add it in style.xml
<style name="AppTheme.NoActionBar" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
<item name="android:windowFullscreen">true</item>
</style>
and use the style at activity of manifest.xml.
<activity ....
android:theme="#style/AppTheme.NoActionBar" > ......
</activity>
The ActionBar usually exists along Fragments so from the Activity you can hide it
getActionBar().hide();
getActionBar().show();
and from the Fragment you can do it
getActivity().getActionBar().hide();
getActivity().getActionBar().show();
This works for me! Put this in your Activity in manifests
<activity
// ...
android:theme="#style/Theme.AppCompat.Light.NoActionBar"
// ...
</activity>
You can also make your custom theme in styles.xml like this:
<style name="Theme.MyCustomTheme" parent="#style/Theme.AppCompat.Light.NoActionBar">
<item name = "android:windowActionBar">false</item>
<item name = "android:windowNoTitle">true</item>
// more custom...
</style>
Hope this help.
If you were using Theme.AppCompat.Light, a better equivalent would be Theme.AppCompat.Light.NoActionBar.
I found that using Theme.AppCompat.NoTitleBar caused my button text to be invisible so I am using Theme.AppCompat.Light.NoActionBar.
<activity android:name=".Activity"
android:label="#string/app_name"
android:theme="#android:style/Theme.AppCompat.Light.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
To hide the ActionBar add this code into java file.
ActionBar actionBar = getSupportActionBar();
actionBar.hide();
You can use Low Profile mode
See here
Just search for SYSTEM_UI_FLAG_LOW_PROFILE that also dims the navigation buttons if they are present of screen.
Apply the following in your Theme for the Activity in AndroidManifest.xml:
<activity android:name=".DashboardActivity"
android:theme="#style/AppFullScreenTheme">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
Then Apply the following in your Style in style.xml
<style name="AppFullScreenTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="android:windowNoTitle">true</item>
<item name="android:windowActionBar">false</item>
<item name="android:windowFullscreen">true</item>
<item name="android:windowContentOverlay">#null</item>
</style>
The above answers would help with the ActionBar thing. To add to it, use the following code in case you are using the Splash Screen:
Use this before you set the content view:
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
Just to clarify, here's how you do it:
super.onCreate(savedInstanceState);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_main);
This would make your screen a full screen, i.e remove the top bar where you see the network bar, etc
#Override
public void onResume() {
super.onResume();
getSupportActionBar().hide();
}
#Override
public void onStop() {
super.onStop();
getSupportActionBar().show();
}
For selectively hiding Actionbar in activities:
Add the following code to onCreate (preferably on the last line of the function)
Kotlin:
supportActionBar?.hide()
Java:
getSupportActionBar().hide();
This works in API 27
In the styles.xml replace code to the following....
<resources>
<!-- No Action Bar -->
<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>
</resources>
Then in the files (eg. activity_list.xml) in which you do want to have a toolbar put the following code.
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:background="#color/colorPrimary"/>
If you have problems switch to linear layout (because that is what this code is tested on)
From here:
Beginning with Android 3.0 (API level 11), all activities that use the default theme have an ActionBar as an app bar. However, app bar features have gradually been added to the native ActionBar over various Android releases. As a result, the native ActionBar behaves differently depending on what version of the Android system a device may be using. By contrast, the most recent features are added to the support library's version of Toolbar, and they are available on any device that can use the support library.
So one option is to disable ActionBar completely (in the app manifest.xml file) and then add Toolbar in every page that needs an ActionBar.
(follow the above link for step-by-step explanation)
Add New Style in your style.xml
<!-- 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>
<style name="LoginTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
</style>
and then add following line in your manifest
<activity android:name=".Login"
android:label="#string/app_name"
android:theme="#style/LoginTheme"
>
If you activity extends AppCompatActivity then you can add this line
super.getSupportActionBar().hide(); before setContentView()
Replace AndroidManifest.xml
android:theme="#style/FullscreenTheme"
to
android:theme="#style/Theme.Design.NoActionBar"
Check for padding attribute if the issue still exists after changing theme.
Padding Issue creating a white space on top of fragment window / app window
Once you remove the padding - top value automatically the white space is removed.
First cheek MainActivity for activity tag,Like -
public class MainActivity extends AppCompatActivity
Then goto menifest xml file and write-
android:theme="#style/Theme.AppCompat.Light.NoActionBar"
in activity tag

It takes 7-10 seconds, I want to know there is a way to reduce the time. Before I installed the splash screen, the home page is loaded in 2-3 seconds. I have installed react-native-splash-screen package and configured the android files automatically by using #bam.tech/react-native-make.
Never tried on a real device, if you want to know.

Try adding this in Style.xml
<item name="android:windowDisablePreview">true</item>
This will remove the white screen which appears in the start.
my Splash activity doesn't change, it only changes if I change the name to another.
For example:
"SplashActivity" - Start with a Modification
If I change the theme to another color, I need to rename the activity to:
"SplashActivityy" or some other name than it was.
If I go back to the name "SplashActivity" the modification goes back to later.
Already formatted and cleared cache of android studio, this did not help!

EDIT: problems just like mine:
Splash Theme is not changing anymore
EDIT 2:
I asked a question in a thread to find out what was going on in my code, after a while fidgeting I didn't find walks on the internet related.
Already tried to clear cache, recreate the application, cleared the cache of files, already did everything in android studio.
After a while I found something talking to restart the application that would appear to change.
But I do not want the user to install my application to have to restart the application to appear the changes in the theme. How can I solve this problem?
As i Deeply analysed the code and i found no reason for that "What you are saying" in the code. So what could be a reason according to me is:
Maybe that you have multiple drawable folder and the file background_splash.xml is present in your device specific drawable folder that might be drawable-xxhdpi and also in drawable
& most probably you are doing change in drawable that don't relates to your device.
So kindly verify it, Same for styles also "if applicable".
other measures you can take are
Make Instant run disable.
Uninstall the app after delete data and
clear cache from app info> storage option of phone and then install again.
Hope any of the above technique will work for you.
Try this:
<style name="SplashTheme" parent="Theme.AppCompat.NoActionBar">
<item name="windowActionBar">false</item>
<item name="android:windowBackground">#drawable/background_splash</item>
</style>
Are you sure that android.intent.action.MAINACTIVITY exists?
There are issues with the incremental build system "Instant Run" of android studio. This is why they have introduced new/improved incremental build called "Apply Changes" as result of project Marble. It is available in android studio version 3.5. Please see the documentation here
Try to change android:allowBackup="true" to android:allowBackup="false". Install the app. Then completely deinstall it. Install it again. Look at the theme. Then change the theme and reinstall - check if the theme is changed.
I'm creating a music application when designing kits, I think I need to create a full screen activity I have tried
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
But that's not what I want, I want full screen but still retain notification bar
How to do this?
Thank!
In your theme:
<item name="android:statusBarColor">#android:color/transparent</item>
<item name="android:windowNoTitle">true</item>
<item name="android:windowTranslucentStatus">true</item>
In your activity onCreate:
Window window = getWindow();
WindowManager.LayoutParams winParams = window.getAttributes();
winParams.flags &= ~WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS;
window.setAttributes(winParams);
window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
Remove getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN); this line from your code and just put change int your activity style.
<style name="LoginTheme" 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>
Manifest.xml
<activity android:name=".Login"
android:theme="#style/LoginTheme">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
Put this code above setContentView()
requestWindowFeature(Window.FEATURE_ACTION_BAR_OVERLAY);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
How to remove two toolbars from a fragment?
((AppCompatActivity)getActivity()).getSupportActionBar().hide();
even after using this command the second blank toolbar remains and the top toolbar disappears.
Use NoActioonBar Theme instead of Default one in Manifest file
<activity .....
android:theme="#style/Theme.AppCompat.NoActionBar"
/>
add no action bar line in manifest
<activity
android:name=".MainActivity"
android:theme="#style/AppTheme.NoActionBar" />
then add in your styles.xml
<style name="AppTheme.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
I've searched SO but not found similar questions as I'm not sure how to phase it in a sentence. I am using ActionBarSherlock, with a logo instead of the launcher icon (i.e. 72x72 icon) with text in the top corner of the activity.
When the activity loads for the first time, for a fraction of a second. I see the launcher icon and label defined in the manifest (as below), before the action bar appears with the logo. This home activity is very simple, so its not doing any additional loading which could cause a delay.
<application
android:hardwareAccelerated="true"
android:icon="#drawable/launcher_icon"
android:label="#string/app_name"
android:screenOrientation="portrait" >
<activity
android:name=".SplashScreenActivity"
android:label="#string/app_name"
android:logo="#drawable/ab_logo"
android:theme="#android:style/Theme.Light.NoTitleBar" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".HomeActivity"
android:label="#string/homeitle"
android:logo="#drawable/ab_logo"
android:theme="#style/MyTheme" >
</activity>
</application>
I can make the text "disappear" by styling it to be the same colour as the background, but i cant find a way to remove/hide the launcher icon from the activity.
I have setup a splashscreen activity (as in manifest above), which just loads my home activity where the issue occurs. This does help, but sometimes the issue still occurs when loading the activity.
public class SplashScreenActivity extends Activity
{
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
}
#Override
public void onResume()
{
super.onResume();
Intent i = new Intent(getBaseContext(), HomeActivity.class);
startActivity(i);
finish();
}
}
Does anyone know of a way to hide the launcher icon & title label, so that it doesn't show up prior to ActionBarSherlock being displayed? Ideally so a splash screen is not needed, as there are several ways to access the activity which would avoid the splashscreen shown above.
--- Update My Theme File ----

Fixed it by adding icon to the style, which is the same as the logo. This overrides the launcher icon.
