Question

Is it possible to animate a change in TextView‘s actual text content an Android? If yes, how would one do this? Links to offsite resources also appreciated.

Answer 1

I will tell you step by step. This is for the fade-in animation.

1. Create an XML file in the anim folder in resources by any name. Code of XML is below:

   <?xml version="1.0" encoding="UTF-8"?>
   <set xmlns:android="http://schemas.android.com/apk/res/android">
       <alpha
           android:fromAlpha="0.0"
           android:toAlpha="1.0"
           android:interpolator="@android:anim/accelerate_interpolator" 
           android:duration="1600"
           android:repeatCount="0" />
   </set>
   

2. Create the object Animation animation; globally

3. Load the animation

   animation = AnimationUtils.loadAnimation(this, R.anim.fadein);
   

4. Set the animation on TextView

   tv.startAnimation(animation);
   

By this way you can use any type of animation.
