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("");
