Hide app title on support.v7.widget.toolbar

I'm starting to develop a new app and I'm triying to give it a material design look. For this, I'm using the v7 support compatibility.

In some activities of the app, I need the toolbar not to show the app title that, I don't know how, but it is showing by default. In those activities, I have a textview at the right side of the toolbar that acts like a button, and where I have implemented traex's RippleEffect.

So, basically my question is, how can I hide the app's title from the toolbar? Because even if I do:

toolbar.setTitle("");


or

toolbar.setTitle(null);


it continues appearing.

This is my code:

Custom toolbar xml [toolbar_intro.xml]:

<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:local="http://schemas.android.com/apk/res-auto"
xmlns:ripple="http://schemas.android.com/apk/res-auto"
xmlns:app="http://schemas.android.com/tools"
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="?attr/actionBarSize"
android:background="?attr/colorPrimary"
android:elevation="4dp"
local:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
local:popupTheme="@style/ThemeOverlay.AppCompat.Light">

<com.andexert.library.RippleView
android:id="@+id/more"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_gravity="right"
android:layout_marginRight="40dp"
ripple:rv_centered="false"
app:rv_rippleDuration="1">

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/toolbar_text"
android:textColor="@color/White"
android:textStyle="bold"
android:textSize="25sp"
android:text="Next"/>
</com.andexert.library.RippleView>
</android.support.v7.widget.Toolbar>


This is how I include the toolbar in the layout:

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

<include
android:id="@+id/toolbar"
layout="@layout/toolbar_intro" />

<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content">

<ImageView
...

</RelativeLayout>
</LinearLayout>


And this is the activity:

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

toolbar= (Toolbar) findViewById(R.id.toolbar);
if (toolbar != null) {
setSupportActionBar(toolbar);
toolbar.setTitle("");
}

TextView toolbar_text = (TextView) toolbar.findViewById(R.id.toolbar_text);
toolbar_text.setText(R.string.next);

...

}


Also, this is the style that I have implemented:

<style name="MaterialTheme.Base" parent="Theme.AppCompat.Light.NoActionBar">

Answer

Use

getSupportActionBar().setDisplayShowTitleEnabled(false);
