How do you remove the title text from the Android

问题:

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?

回答1:

Try:

getActionBar().setDisplayShowTitleEnabled(false);

For v.7:

getSupportActionBar().setDisplayShowTitleEnabled(false);

回答2:

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="">

回答6:

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

回答7:

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();

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

回答9:

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.

回答10:

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

回答11:

getSupportActionBar().setDisplayShowTitleEnabled(false);
    getSupportActionBar().hide();

hope this will help

回答12:

Use the following:

requestWindowFeature(Window.FEATURE_NO_TITLE);

回答13:

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);

回答14:

The only thing that really worked for me was to add:

<activity 
    android:name=".ActivityHere"
    android:label=""
>

回答15:

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

this.setTitle("");

in your Activity

回答16:

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.

回答17:

Simply extends your java file from AppCompatActivity and do this:

ActionBar actionBar = getSupportActionBar(); // support.v7
actionBar.setTitle(" ");

回答18:

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>

回答19:

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....

回答20:

ActionBar actionBar = getActionBar();
actionBar.setTitle("");
