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

Question

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.

Solution 1

Found the solution:

Instead of:

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

I used:

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

And it works.

Solution 2

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);

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.

Solution 4

Simply you can change any activity name by using

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

Solution 5

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">
