[android] In android app Toolbar.setTitle method has no effect – application name is shown as title

I'm trying to create simple application using android-support-v7:21 library.

Code snippets:
MainActivity.java

public class MainActivity extends ActionBarActivity {

    Toolbar mActionBarToolbar;

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

        mActionBarToolbar = (Toolbar) findViewById(R.id.toolbar_actionbar);            
        mActionBarToolbar.setTitle("My title");
        setSupportActionBar(mActionBarToolbar);
}

activity_main.xml

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    android:orientation="vertical">

    <android.support.v7.widget.Toolbar            
        android:id="@+id/toolbar_actionbar"
        android:background="@null"
        android:layout_width="match_parent"
        android:layout_height="?actionBarSize"
        android:fitsSystemWindows="true" />

</LinearLayout>

But instead of "My title" on Toolbar %application name% is shown.
Seems like setTitle method has no effect.
I would like to show "My title".

UPD: Before, styles.xml was:

<style name="AppTheme" parent="Theme.AppCompat">
    <item name="windowActionBar">false</item>
</style>

So, I thought that actionbar is not used. I add NoActionBar to style parent:

<style name="AppTheme" parent="Theme.AppCompat.NoActionBar">
    <item name="windowActionBar">false</item>
</style>

But the problem is not resolved.

Simply use this in your adapter, Where MainActivity is your AppCompactActivity. Call it from anywhere.

((MainActivity) context).getSupportActionBar().setTitle(titles.get(position));

Make sure you add this option:

getSupportActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_TITLE);

This can be done by setting the android:label attribute of your activity in the AndroidManifest.xml file:

<activity android:name="my activity"
 android:label="The Title I'd like to display" />

And then add this line to the onCreate():

getSupportActionBar().setDisplayShowTitleEnabled(true);

The answer is in the documentation (which you can find here):

To use the ActionBar utility methods, call the activity's getSupportActionBar() method. This method returns a reference to an appcompat ActionBar object. Once you have that reference, you can call any of the ActionBar methods to adjust the app bar. For example, to hide the app bar, call ActionBar.hide().

That is the solution you actually found. Just thought of giving a reference to the official documentation (which apparently few tend to read).

To change the title for each different activity

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_pizza);
    setTitle(getResources().getText(R.string.title));
}

If your goal is to set a static string in the toolbar, the easiest way to do it is to simply set the activity label in AndroidManifest.xml:

<activity android:name=".xxxxActivity"
          android:label="@string/string_id" />

The toolbar will get this string without any code. (works for me with v27 libraries.)

If you are using CollapsibleToolbarLayout along with Toolbar then you will need to set title in both the layouts

set your Toolbar as action bar in onCreate method

protected void setUpToolBar() {

    if (mToolbar != null) {
        ((HomeActivity) getActivity()).setSupportActionBar(mToolbar);
        mToolbar.setTitleTextColor(Color.WHITE);
        mToolbar.setTitle("List Detail");
        mToolbar.setNavigationOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                getActivity()
                        .getSupportFragmentManager().popBackStack();
            }
        });
        ((HomeActivity) getActivity()).getSupportActionBar()
                .setDisplayHomeAsUpEnabled(true);
    }
}

Later simply update title of toolbar using setTitle method

 mToolbar .setTitle(productFromShoppingList.getProductName()); 
 mCollapsingToolbar.setTitle(productFromShoppingList.getProductName());

For anyone who needs to set up the title through the Toolbar some time after setting the SupportActionBar, read this.

The internal implementation of the support library just checks if the Toolbar has a title (not null) at the moment the SupportActionBar is set up. If there is, then this title will be used instead of the window title. You can then set a dummy title while you load the real title.

mActionBarToolbar = (Toolbar) findViewById(R.id.toolbar_actionbar);
mActionBarToolbar.setTitle("");
setSupportActionBar(mActionBarToolbar);

later...

mActionBarToolbar.setTitle(title);

Try this .. this method works for me..!! hope it may help somebody..!!

<android.support.v7.widget.Toolbar  
 xmlns:app="http://schemas.android.com/apk/res-auto"  
 android:id="@+id/my_awesome_toolbar"  
 android:layout_width="match_parent"  
 android:layout_height="wrap_content"  
 android:background="?attr/colorPrimary"  
 android:minHeight="?attr/actionBarSize"  
 app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar" >  

<TextView  
   android:id="@+id/toolbar_title"  
   android:layout_width="wrap_content"  
   android:layout_height="wrap_content"  
   android:gravity="center"  
   android:singleLine="true"  
   android:text="Toolbar Title"  
   android:textColor="@android:color/white"  
   android:textSize="18sp"  
   android:textStyle="bold" />  

</android.support.v7.widget.Toolbar>  

To display logo in toolbar try the below snippet. // Set drawable

toolbar.setLogo(ContextCompat.getDrawable(context, R.drawable.logo));

Let me know the result.

It's not just about .setTitle

more methods of Support Toolbar (Appcompat v7) in onCreate works only with

getSupportActionBar().method()

and don't work with mToolbar.method()

examples:

getSupportActionBar().setTitle("toolbar title");
getSupportActionBar().setDisplayHomeAsUpEnabled(true);

though next methods works fine without getSupportActionBar() in onCreate

mToolbar.setVisibility(View.VISIBLE);
mToolbar.setNavigationOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        //
    }

Problem only with onCreate event, you still can use mToolbar.setTitle() later instead of annoying getSupportActionBar().setTitle(), for example if you add this in onCreate it will work (because it will be executed later, after onCreate)

mHandler.post(new Runnable() {
    @Override
    public void run() {
        mToolbar.setTitle("toolbar title");
    }
});

I prefer to use this solution https://stackoverflow.com/a/35430590/4548520 than https://stackoverflow.com/a/26506858/4548520 because if you change title many times (in different functions) it's more comfortable to use mToolbar.setTitle() than longer getSupportActionBar().setTitle() one and you don't see annoying notification about null exception like with getSupportActionBar().setTitle()

Simply you can change any activity name by using

Activityname.this.setTitle("Title Name");

I made it work by using -

toolbar.post(new Runnable() {
            @Override
            public void run() {
                toolbar.setTitle("My Title");
            }
        });

I have a strange behaviour that may can help you.
This is working but it has no effect in onCreate only:

toolbar.setTitle("title");

Try to use this in onCreate:

yourActivityName.this.setTitle("title")

Try this:

Xml Code

<android.support.v7.widget.Toolbar
    android:layout_width="match_parent"
    android:layout_height="120dp"
    android:id="@+id/tool_bar"
    android:background="@color/tablayout"
    android:theme="@style/ToolBarStyle"
    app:popupTheme="@style/ThemeOverlay.AppCompat.Light">
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/app_name"
        android:layout_gravity="center"
        android:id="@+id/toolbar_title"
        android:textSize="18sp"
        android:textColor="@color/white"/>
    </android.support.v7.widget.Toolbar>

Java Code

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    toolbar = (Toolbar) findViewById(R.id.tool_bar);
    toolbar_text = (TextView)findViewById(R.id.toolbar_title);
    setSupportActionBar(toolbar);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    getSupportActionBar().setDisplayShowTitleEnabled(false);
    toolbar.setLogo(R.drawable.ic_toolbar);
}

The above answer is totally true but not working for me.

I solved my problem with the following things.

Actually My XML is like that:

<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/confirm_order_mail_layout"
    android:layout_width="match_parent"
    android:layout_height="fill_parent">

    <android.support.design.widget.AppBarLayout
        android:id="@+id/confirm_order_appbar_layout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

        <android.support.design.widget.CollapsingToolbarLayout
            android:id="@+id/confirm_order_list_collapsing_toolbar"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:fitsSystemWindows="true"
            app:contentScrim="?attr/colorPrimary"
            app:expandedTitleMarginEnd="64dp"
            app:expandedTitleMarginStart="48dp"
            app:layout_scrollFlags="scroll|enterAlways">

            <android.support.v7.widget.Toolbar
                android:id="@+id/confirm_order_toolbar_layout"
                android:layout_width="match_parent"
                android:layout_height="?attr/actionBarSize"
                android:background="?attr/colorPrimary"
                app:layout_scrollFlags="scroll|enterAlways"
                app:popupTheme="@style/ThemeOverlay.AppCompat.Light">

            </android.support.v7.widget.Toolbar>
        </android.support.design.widget.CollapsingToolbarLayout>
    </android.support.design.widget.AppBarLayout>
</android.support.design.widget.CoordinatorLayout>

I have tried all the option and after all I just removed CollapsingToolbarLayout because of i do not need to use in that particular XML So My Final XML is like:

<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/confirm_order_mail_layout"
    android:layout_width="match_parent"
    android:layout_height="fill_parent">

    <android.support.design.widget.AppBarLayout
        android:id="@+id/confirm_order_appbar_layout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

        <android.support.v7.widget.Toolbar
            android:id="@+id/confirm_order_toolbar_layout"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            app:layout_scrollFlags="scroll|enterAlways"
            app:popupTheme="@style/ThemeOverlay.AppCompat.Light">

        </android.support.v7.widget.Toolbar>
    </android.support.design.widget.AppBarLayout>
</android.support.design.widget.CoordinatorLayout>

Now you have to use setTitle() like above answer:

mActionBarToolbar = (Toolbar) findViewById(R.id.confirm_order_toolbar_layout);            
setSupportActionBar(mActionBarToolbar);
getSupportActionBar().setTitle("My Title");

Now If you want to use CollapsingToolbarLayout and Toolbar together then you have to use setTitle() of CollapsingToolbarLayout

CollapsingToolbarLayout collapsingToolbarLayout = (CollapsingToolbarLayout) findViewById(R.id.confirm_order_mail_layout);
collapsingToolbarLayout.setTitle("My Title");

May it will helps you. Thank you.

Application title will not show as default title on every activity, you can insert different title on every activity. On your activity file bellow the onCreate just paste a single line to set title,

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        setTitle("Your Title Here");

Just change the text "Your Title Here" to your text.

This is happening because you are using Toolbar and ActionBar both. Now as you want to use Toolbar as an action bar, the first thing you need to do is disable the decor provided action bar.

The easiest way is to have your theme extend from Theme.AppCompat.NoActionBar.

 getSupportActionBar().setTitle("Your Title");

Try this, you can define title directly in XML:

 <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        app:title="some title"
        app:popupTheme="@style/AppTheme.PopupOverlay">

I tried to rename the toolbar from the fragment

It helped me, I hope to help someone else

Activity activity = this.getActivity();
Toolbar toolbar = (Toolbar) activity.findViewById(R.id.detail_toolbar);
        if (toolbar != null) {
            activity.setTitle("Title");
        }

//toolbar.setTitle("Title"); did not give the same results

Screenshot:

Please see https://code.google.com/p/android/issues/detail?id=77763. Apparently it is supposed to work like that. Once you call the setSupportActionBar() method call, it then is the responsibility of the ActionBar delegate to route the call to the correct view.

 public class MainActivity extends AppCompatActivity implements View.OnClickListener {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);

       //custom toolbaar
       getSupportActionBar().setTitle("Abhijeet");

    }
}

For anyone who needs to set up the title through the Toolbar some time after setting the SupportActionBar (@sorianiv) AND your Toolbar is inside a CollapsingToolbarLayout, read this:

mToolbarLayout = (CollapsingToolbarLayout) findViewById(R.id.toolbar_layout);
Toolbar toolbar = findViewById(R.id.toolbar);
//toolbar.setTitle(""); // no need to do this
//mToolbarLayout.setTitle("Title"); // if you need an initial title, do this instead
setSupportActionBar(toolbar);

Then later,

mToolbarLayout.setTitle("New Title");

To set the title for each Navbar fragment title

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) 
{
    myView = inflater.inflate(R.layout.second_layout, container, false);
    getActivity().setTitle("title");

    return myView;
}

Though not immediately relevant to this particular setup, I found that removing "CollapsingToolbarLayout" from my XML that was wrapping my toolbar inside of an AppBarLayout made everything work.

So, this:

      <android.support.design.widget.AppBarLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content">

            <android.support.v7.widget.Toolbar
                android:id="@+id/toolbar"
                android:layout_height="?attr/actionBarSize"
                app:layout_scrollFlags="scroll|enterAlways"
                app:navigationIcon="@drawable/ic_arrow_back_white_24dp" />

        </android.support.design.widget.AppBarLayout>

Instead of this:

        <android.support.design.widget.AppBarLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content">

            <android.support.design.widget.CollapsingToolbarLayout
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:id="@+id/collapsingToolbar"
                android:minHeight="?attr/actionBarSize"
                app:layout_scrollFlags="enterAlways|scroll|snap">

                <android.support.v7.widget.Toolbar
                    android:id="@+id/toolbar"
                    android:layout_height="?attr/actionBarSize"
                    app:navigationIcon="@drawable/ic_arrow_back_white_24dp" />
            </android.support.design.widget.CollapsingToolbarLayout>

        </android.support.design.widget.AppBarLayout>

Then, I set the title in the activity's onCreate, before setSupportActionBar() is called.

In Kotlin you can do this:

import android.os.Bundle
import androidx.appcompat.app.AppCompatActivity
import androidx.appcompat.widget.Toolbar

class SettingsActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_settings)

        val toolbar = findViewById<Toolbar>(R.id.toolbar)
        setSupportActionBar(toolbar)
        supportActionBar?.setDisplayHomeAsUpEnabled(true)
        supportActionBar?.setTitle(R.string.title)

    }

    override fun onSupportNavigateUp() = true.also { onBackPressed() }

}
