Remove title in Toolbar in appcompat-v7

The documentation of Toolbar says

> If an app uses a logo image it should strongly consider omitting a title and subtitle.

What is the proper way to remove the title?

getSupportActionBar().setDisplayShowTitleEnabled(false);

The correct way to hide/change the Toolbar Title is this:

Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setTitle(null);

This because when you call setSupportActionBar(toolbar);, then the getSupportActionBar() will be responsible of handling everything to the Action Bar, not the toolbar object.

See here

Try this...

 @Override
 protected void onCreate(Bundle savedInstanceState) {
	super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_landing_page); 

    .....

    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar_landing_page);
	setSupportActionBar(toolbar);
	getSupportActionBar().setDisplayShowTitleEnabled(false);

    .....

 }

The reason for my answer on this is because the most upvoted answer itself failed to solve my problem. I have figured out this problem by doing this.

<activity android:name="NAME OF YOUR ACTIVITY"
    android:label="" />

Hope this will help others too.

Another way to remove the title from your Toolbar is to null it out like so:

Toolbar toolbar = (Toolbar) findViewById(R.id.my_awesome_toolbar);
toolbar.setTitle(null);

this

Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    getSupportActionBar().setDisplayShowTitleEnabled(false);
    //toolbar.setNavigationIcon(R.drawable.ic_toolbar);
    toolbar.setTitle("");
    toolbar.setSubtitle("");
    //toolbar.setLogo(R.drawable.ic_toolbar);

If you are using Toolbar try below code:

toolbar.setTitle("");

 Toolbar actionBar = (Toolbar)findViewById(R.id.toolbar);
    actionBar.addView(view);
    setSupportActionBar(actionBar);
    getSupportActionBar().setDisplayShowTitleEnabled(false);

take note of this line getSupportActionBar().setDisplayShowTitleEnabled(false);

You can use any one of bellow as both works same way: getSupportActionBar().setDisplayShowTitleEnabled(false); and getSupportActionBar().setTitle(null);

Where to use:

Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        getSupportActionBar().setDisplayShowTitleEnabled(false);

Or :

Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 
    setSupportActionBar(toolbar); 
    getSupportActionBar().setTitle(null);

Just add this attribute to your toolbar

app:title=" "

The correct way to hide title/label of ToolBar the following codes:

  Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    getSupportActionBar().setTitle(null);

I dont know whether this is the correct way or not but I have changed my style like this.

<style name="NoActionBarStyle" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="windowActionBar">false</item>
    <item name="android:windowNoTitle">true</item>
</style>

Toolbar toolbar = findViewById(R.id.myToolbar);
    toolbar.setTitle("");

if your using default toolbar then you can add this line of code

Objects.requireNonNull(getSupportActionBar()).setDisplayShowTitleEnabled(false);

Nobody mentioned:

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        supportRequestWindowFeature(Window.FEATURE_NO_TITLE);
        super.onCreate(savedInstanceState);
    }

toolbar.setTitle(null);// remove the title

It's obvious, but the App Theme selection in design is just for display a draft during layout edition, is not related to real app looking in cell phone. In my case, there is no title bar in design but the title bar was always in cell phone.

I'm starting with Android programming and fight to discover a right solution.

Just change the manifest file (AndroidManifest.xml) is not enough because the style need to be predefined is styles.xml. Also is useless change the layout files.

All proposed solution in Java or Kotlin has failed for me. Some of them crash the app. And if one never (like me) intend to use the title bar in app, the static solution is cleaner.

For me the only solution that works in 2019 (Android Studio 3.4.1) is:

in styles.xml (under app/res/values) add the lines:

   <style name="AppTheme.NoActionBar">
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>
    </style>

After in AndroidManifest.xml (under app/manifests)

Replace

android:theme="@style/AppTheme">

by

android:theme="@style/AppTheme.NoActionBar">

Just adding an empty string in the label of <application> (not <activity>) in AndroidMenifest.xmllike that -

<application
            android:label=""
            android:theme="@style/AppTheme">
            <activity
             .
             .
             .
             .
            </activity>
    </application>
