Question

I’m trying to create an animation in my android app.

I want the animation like the credits of Star Wars the movie, where a text goes up gradually. If there is another way to do it than I’d like to know.

Answer 1

Try this :

Put this piece of code in an xml file in res/anim/animationfile.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/linear_interpolator" >

<translate
    android:duration="5000" ---> set your time here
    android:fromYDelta="-100%p"
    android:toYDelta="100%p" /> </set>

Now to set the animation, do this :

Animation translatebu= AnimationUtils.loadAnimation(this, R.anim.animationfile);
tv.setText("Some text view.");
tv.startAnimation(translatebu);

This is how you do it roughly.
