Android FragmentTransaction Custom Animation (Unknown Animator Name: Translate)

Question

I'm trying to get a custom animation to work with my fragment.

I've followed the online tutorials but I've been getting the below error:

java.lang.RuntimeException: Unknown animator name: translate

The XML for the animation is below:

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate
    android:fromXDelta="100%"
    android:toXDelta="0"
    android:duration="300" />
</set>

The Java file is shown below:

public void goCategory(View v) {        
    FragmentTransaction ft = fm.beginTransaction();     
    ft.setCustomAnimations(R.animator.anim_in_left, R.animator.anim_out_left);              
    ft.show(fragment);
    ft.commit();
}

I'm having trouble understanding the solutions in the other threads. If someone could dumb it down for me, I'd really appreciate it.

If you're using the animation with the support library version of Fragment, then that might be your problem. — type-a1pha, Jul 20 '13 at 08:35

Probably you are mixing two apis. There are two cases:

If targeting below 3.0 or using support v4 fragments: You have to use the old animations api, that is, the one you are using (they go into anim/, and are R.anim.thing)
If you are targeting above 3.0 and using native fragments: You have to use the new animation apis, that is, ObjectAnimators (they go into animator/ and are R.animator.thing).

Would you happen to know where in the documentation does it say you have to use object animators for native fragments? – kmdupr33 Aug 06 '14 at 13:04

I checked the source code of both the Api and find that all the animation xml should go into res/anim folder, didn't see any parsing to animator/ – Lei Guo Dec 09 '14 at 08:56

It will not work, you should use object animator

animator/slide_in_left.xml

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

    <objectAnimator
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:duration="500"
        android:propertyName="x"
        android:valueFrom="1000"
        android:valueTo="0"
        android:valueType="floatType" />

</set>

animator/slide_out_right.xml

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

    <objectAnimator
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:duration="500"
        android:propertyName="x"
        android:valueFrom="0"
        android:valueTo="-1000"
        android:valueType="floatType" />

</set>

Class Subcategory

 public View onCreateView(LayoutInflater inflater, ViewGroup container,
                Bundle savedInstanceState) {
            // TODO Auto-generated method stub
            // return super.onCreateView(inflater, container, savedInstanceState);

            View view = (ViewGroup) inflater.inflate(R.layout.product_frame, null);
            getFragmentManager().beginTransaction()
                    .replace(R.id.sub_header, new Sub_Header()).commit();
            getFragmentManager()
                    .beginTransaction()
                    .setCustomAnimations(R.animator.slide_in_left,
                            R.animator.slide_out_right, 0, 0)
                    .replace(R.id.product_frame, new Sub_Catagory_Grid()).commit();

            view.getWidth();
            return view;

        }

He's referring to your statement that the OP's solution won't work, and asking for clarification. – Tom Aug 14 '14 at 05:13

To the person who don't know why "translate animation" does not work for new Api: by reading the source code(Api 19), it only support "objectAnimator" and "animator". – Lei Guo Dec 09 '14 at 09:08

These animations do not provide good effects because they use hard coded translation values. I experienced overlapping one fragment with the other for instance.. I assume different screen sizes would produce different behaviour.. Unfortunately, it is not possible to specify relative translation with objectAnimators. – Sandra Nov 20 '15 at 10:03
shouldn't "from" value of slide_out_right be 1000 and the value of slide_in_left -1000? – muilpp Oct 21 '16 at 08:49
@muilpp This confuses a lot of people but the idea is if it's slide_out_right then it's sliding from the right (to the left side) not sliding out to the right side. – Itay Feldman Jan 27 '21 at 08:47
i have been search far too long for a solution and this was finally it, thank you so much! – mr nooby noob Jun 05 '21 at 18:48

As @minivac replied you are mixing two APIs. Please, take a look to Display Card Flip Animations example from Android training guides to get a further understanding about how to add custom animations to fragment transactions. It solves exactly your issue.
