In the below example I have created Toolbar text animation function. Here In activity_main.xml layout first I have created Toolbar and added a TextView, then In MainActivity I have used ObjectAnimator class. You can see below program it will clearly describe you to create Toolbar text 3D animation in android.

Step(1)-Create actvity_main.xml layout-
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:context="com.tiwari.rajshekhar.objectanimation.MainActivity">

    <android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/AppTheme.AppBarOverlay">

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


                <TextView
                    android:id="@+id/text_view"
                    android:layout_centerInParent="true"
                    android:textAlignment="center"
                    android:textSize="36sp"
                    android:textStyle="bold"
                    android:textColor="#9600FF00"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:text="Rajshekhar" />



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

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

    <include layout="@layout/content_main" />



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

Step(2)-MainActivity-

public class MainActivity extends Activity {

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
            View v = findViewById(R.id.text_view);
            ObjectAnimator animation = ObjectAnimator.ofFloat(v, "rotationY", 0.0f, 360f);
            animation.setDuration(3600);

            animation.setRepeatCount(ObjectAnimator.INFINITE);

            animation.setInterpolator(new AccelerateDecelerateInterpolator());
            animation.start();
        }

    }
