How do you remove the title text from the Android ActionBar?
I'm looking through the Holo.开发者_JAVA技巧Light
theme, and I can't seem to find the magic style to override to get rid of the title text that briefly shows up when my app first launches.
How can I do that?
Try:
getActionBar().setDisplayShowTitleEnabled(false);
For v.7:
getSupportActionBar().setDisplayShowTitleEnabled(false);
I think this is the right answer:
<style name="AppTheme" parent="Theme.Sherlock.Light.DarkActionBar">
<item name="actionBarStyle">@style/Widget.Styled.ActionBar</item>
<item name="android:actionBarStyle">@style/Widget.Styled.ActionBar</item>
</style>
<style name="Widget.Styled.ActionBar" parent="Widget.Sherlock.Light.ActionBar.Solid.Inverse">
<item name="android:displayOptions">showHome|useLogo</item>
<item name="displayOptions">showHome|useLogo</item>
</style>
I'm very new to Android so correct me if I'm wrong, but I think if you decide to use navigation tabs on the Action Bar, they seemed to not be completely left aligned because the title text color is only transparent and hasn't gone away.
<style name="CustomActionBarStyle" parent="@android:style/Widget.Holo.ActionBar">
<item name="android:displayOptions">useLogo|showHome</item>
</style>
worked for me.
Got it. You have to override
android:actionBarStyle
and then in your custom style you have to override
android:titleTextStyle
Here's a sample.
In my themes.xml:
<style name="CustomActionBar" parent="android:style/Theme.Holo.Light">
<item name="android:actionBarStyle">@style/CustomActionBarStyle</item>
</style>
And in my styles.xml:
<style name="CustomActionBarStyle" parent="android:style/Widget.Holo.ActionBar">
<item name="android:titleTextStyle">@style/NoTitleText</item>
<item name="android:subtitleTextStyle">@style/NoTitleText</item>
</style>
<style name="NoTitleText">
<item name="android:textSize">0sp</item>
<item name="android:textColor">#00000000</item>
</style>
I'm not sure why setting the textSize to zero didn't do the trick (it shrunk the text, but didn't make it go away), but setting the textColor to transparent works.
In your Manifest
<activity android:name=".ActivityHere"
android:label="">
Write this statement under
setContentView(R.layout.activity_main);
getSupportActionBar().setDisplayShowTitleEnabled(false);
if extending AppCompactActivity use getSupportActionbar()
if extending Activity use getActionBar()
else it may give
null pointer exception
using android:label=""
in AndroidManifest.xml
for activity also works but your app won't appear in Recently used apps
you have two choice:
first:
getActionBar().setDisplayShowTitleEnabled(false);
If usign getActionBar()
produced null pointer exception, you should use getSupportActionBar()
Second
getSupportActionBar().setTitle("your title");
or
getSupportActionBar().setDisplayShowTitleEnabled(false);
getSupportActionBar().hide();
You can change the style applied to each activity, or if you only want to change the behavior for a specific activity, you can try this:
setDisplayOptions(int options, int mask) --- Set selected display
or
setDisplayOptions(int options) --- Set display options.
To display title on actionbar, set display options in onCreate()
getSupportActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_TITLE, ActionBar.DISPLAY_SHOW_TITLE);
To hide title on actionbar.
getSupportActionBar().setDisplayOptions(0, ActionBar.DISPLAY_SHOW_TITLE);
Details here.
i use this code in App manifest
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:logo="@drawable/logo2"
android:label="@string/title_text"
android:theme="@style/Theme.Zinoostyle" >
my logo file is 200*800 pixel and use this code in main activity.java
getActionBar().setDisplayShowTitleEnabled(false);
it will work Corectly
I tried this. This will help -
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayShowTitleEnabled(false);
getSupportActionBar should be called after setSupportActionBar, thus setting the toolbar, otherwise, NullpointerException because there is no toolbar set. Hope this helps
The only thing that really worked for me was to add:
<activity
android:name=".ActivityHere"
android:label=""
>
getSupportActionBar().setDisplayShowTitleEnabled(false);
getSupportActionBar().hide();
hope this will help
If you only want to do it for one activity and perhaps even dynamically, you can also use
ActionBar actionBar = getActionBar();
actionBar.setDisplayOptions(actionBar.getDisplayOptions() ^ ActionBar.DISPLAY_SHOW_TITLE);
as a workaround just add this line incase you have custom action/toolbars
this.setTitle("");
in your Activity
Use the following:
requestWindowFeature(Window.FEATURE_NO_TITLE);
While all of these are acceptable, if your activity only contains a main activity, you can edit res\values\styles.xml
like so:
<resources>
<!-- Base application theme. -->
<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>
I've updated parent
and added the .NoActionBar property to the Light theme from Android Studios Create Blank Application
Wizard.
Simply extends your java file from AppCompatActivity
and do this:
ActionBar actionBar = getSupportActionBar(); // support.v7
actionBar.setTitle(" ");
In your manifest.xml page you can give address to your activity label. the address is somewhere in your values/strings.xml . then you can change the value of the tag in xml file to null.
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="title_main_activity"></string>
</resources>
I am new to Android so maybe I am wrong...but to solve this problem cant we just go to the manifest and remove the activity label
<activity
android:name=".Bcft"
android:screenOrientation="portrait"
**android:label="" >**
Worked for me....
I remove the default appbar and run a custom toolbar instead using Theme.AppCompat.Light.NoActionBar
then add a textview or something that extend to full toolbar width using attribute layout_width=match_parent
and it pushes the title out of the toolbar. If you want to do this, you must study how to make a toolbar.
ActionBar actionBar = getActionBar();
actionBar.setTitle("");
