Here is Toolbar 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:popupTheme="@style/AppTheme.PopupOverlay">
    <TextView
        android:id="@+id/toolbar_title"
        android:textColor="#FFF"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"

JAVA :

    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    TextView mTitle = (TextView) toolbar.findViewById(R.id.toolbar_title);
    /*Start Font Face*/
    Typeface tf = Typeface.createFromAsset(getAssets(), "Limelight.ttf");
    mTitle.setTypeface(tf);
    /*Rnd Font Face */
    setSupportActionBar(toolbar);
    mTitle.setText(toolbar.getTitle());

Answer 1

Use getSupportActionBar().setTitle("") to hide default title.

Try this:

Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);

setSupportActionBar(toolbar);
getSupportActionBar().setTitle("");

TextView mTitle = (TextView) toolbar.findViewById(R.id.toolbar_title);
Typeface tf = Typeface.createFromAsset(getAssets(), "Limelight.ttf");
mTitle.setTypeface(tf);
mTitle.setText("ARTISTIC");
