[SOLVED] Set duration for translate animation in xml

Set duration for translate animation in xml

I just started learning animations and I was wondering how can I set the duration of an animation (scale, translate, rotate etc..) in the XML file?

This is my translate.xml resource file:

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:fromXDelta="-1000"
    android:toXDelta="0">
</translate>

I watched some tutorials on Youtube and noticed that they used android:duration="2000" (this means 2 seconds if I'm not mistaken?), something like this:

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:fromXDelta="-1000"
    android:toXDelta="0"
    android:duration="2000">
</translate>

However, I was unable to add that line of code inside my XML file. I am doing something wrong here?

UPDATE: After multiple times of restarting my Android Studio project, I was able to add that line of code. (Previously the IDE was displaying red squiggly lines)

Solution

everything looks fine, duration should work as TranslateAnimation extends Animation, which handle duration attribute
