You can use Android's AlphaAnimation to make a View invisible with fade out like animation after some time.

AlphaAnimation animation = new AlphaAnimation(1f, 0f);
animation.setStartOffset(5000);
animation.setDuration(1000);
animation.setFillAfter(true);
tv.startAnimation(animation);

Details about AlphaAnimation: https://developer.android.com/reference/android/view/animation/AlphaAnimation.html

Yes it possible using Animation

put this in res/anim folder

alpha_invisible.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:fillAfter="true"
android:fillEnabled="true" >

<alpha
    android:duration="1000"
    android:fromAlpha="1.0"
    android:toAlpha="0.0" />

Java file:

int time = 5000; // 5 sec
    Animation animInvisible = AnimationUtils.loadAnimation(getApplicationContext(), R.anim.alpha_invisible);


    new Handler().postDelayed(new Runnable() {

        @Override
        public void run() {

            textview.startAnimation(animInvisible);
        }
    }, time); // animation invisible textview after 5 sec
