I post a question here because I can't find out a solution to my problem. I read a lot of things about android animation.
I actually develop an android 4.0 app and I need to animate transition between fragments (not layout).
Similary post, worked with layout but no more precision about fragments
Here my uncomplete code :
Activity code
private void showFragment(final Fragment fragment)
{
if (null == fragment)
return;
FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.setCustomAnimations(R.anim.slide_in_left, R.anim.slide_out_right);
ft.replace(R.id.fragment_container_layout, fragment, fragment.getClass().getSimpleName()).commit();
}
R.anim.slide_in_left
<?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="@android:integer/config_mediumAnimTime">
<translate
android:fromXDelta="100%p"
android:toXDelta="0" />
<alpha
android:fromAlpha="0.0"
android:toAlpha="1.0" />
</set>
And finally R.anim.slide_out_right
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="@android:integer/config_mediumAnimTime" >
<translate
android:fromXDelta="0"
android:toXDelta="-100%p" />
<alpha
android:fromAlpha="1.0"
android:toAlpha="0.0" />
</set>
When I run this code, I got an exception : 12-27 15:26:55.566: E/AndroidRuntime(27699): java.lang.RuntimeException: Unknown animator name: translate
Do you have any idea to fix this ?
Problem solved!
Like Piyush Gupta said, I must have a custom subclass of
FrameLayout
perFragment
I need to animate, first.Secondly, I must not use
R.anim
butR.animator
like another similar post (link in question).Thank you all !
