Try these properties. Should be anyone from this.

    android:translationX=""
    android:translationY=""
    android:transformPivotX=""
    android:transformPivotY=""
    android:scaleX=""
    android:scaleY=""

I don't see how that relates to letters of an EditText – 9patchcoder Jul 22 '14 at 18:30
thanks but I still can't apply it ... could you take a look at the video ? because the size and scale of EditText/TextView remains the same after all – 9patchcoder Jul 22 '14 at 18:55
I have Android 5.0 with me. But the text size changes after the zoomin/out animation. – intrepidkarthi Jul 22 '14 at 18:57
exactly ... What i meant was how to animate changing of the text/font size not the whole TextView Size – 9patchcoder Jul 22 '14 at 19:03

for the Animation use this example :

TextView Animation Size

do it in the Callback onTextChanged which occurs when you Type a char in the View

Hope it helps.

also you can use the same Animation to EditText but use this Example for this : EditText addTextChangeListener
