How do you remove the title text from the Android

Question

I'm looking through the Holo.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?

Answer 1

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.

Answer 2

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();

Answer 3

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

Answer 4

as a workaround just add this line incase you have custom action/toolbars

this.setTitle("");

in your Activity

Answer 5

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>

Answer 6

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.
