Come ripristinare le animazioni dei frammenti su BackStack?

Question

ho pensato che il sistema avrebbe animazioni invertire sulla backstack quando viene premuto il pulsante Indietro quando si utilizza frammenti utilizzando il seguente codice:

FragmentManager fm = getFragmentManager(); 
FragmentTransaction ft = fm.beginTransaction(); 
ft.setCustomAnimations(R.anim.slide_in, R.anim.hyperspace_out); 
ft.replace(R.id.viewContainer, new class(), "layout").addToBackStack(null).commit(); 

Answer 1

Secondo il android documentation for custom animation:

Cambio:

ft.setCustomAnimations(R.anim.slide_in, R.anim.hyperspace_out); 

A:

ft.setCustomAnimations(R.anim.slide_in, R.anim.hyperspace_out, R.anim.hyperspace_in, R.anim.slide_out); 

e ora il backstack si anima - Al contrario !!

Answer 2

Utilizzare l'animazione corretta Ho usato il seguente ed il suo lavoro come un fascino

slide_in_left.xml

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

slide_in_right.xml

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

    <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> 

slide_out_left .xml

<set xmlns:android="http://schemas.android.com/apk/res/android" 
    android:duration="@android:integer/config_mediumAnimTime" > 

    <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> 

slide_out_right.xml

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

    <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> 

quindi utilizzare seguente aggiungendo frammento

setCustomAnimations(R.anim.slide_in_left, R.anim.slide_out_left, 
           R.anim.slide_out_right, R.anim.slide_in_right) 

e sarà lavorato 100%

Answer 3

.setCustomAnimations(R.animator.fragment_fade_in, 
     R.animator.fragment_fade_out, 
     R.animator.fragment_fade_p_in, 
     R.animator.fragment_fade_p_out) 

Sostituire il precedente con:

mFragmentManager.beginTransaction() 
    .setCustomAnimations(R.animator.fragment_fade_in, 
      R.animator.fragment_fade_out, 
      R.animator.fragment_fade_p_in, 
      R.animator.fragment_fade_p_out) 
    .replace(R.id.main_container, FragmentPlayerInfo.getInstance(data)) 
    .addToBackStack(FragmentPlayerInfo.TAG) 
    .commit(); 

Answer 4

nel mio caso

ft.setCustomAnimations(android.R.anim.slide_in_left, android.R.anim.slide_out_right, 
         R.anim.slide_in_right, R.anim.slide_out_left); 

creerebbe animazioni perfette.

slide_in_right

<?xml version="1.0" encoding="utf-8"?> 
<set xmlns:android="http://schemas.android.com/apk/res/android"> 
    <translate android:fromXDelta="50%p" android:toXDelta="0" 
       android:duration="@android:integer/config_mediumAnimTime"/> 
    <alpha android:fromAlpha="0.0" android:toAlpha="1.0" 
      android:duration="@android:integer/config_mediumAnimTime" /> 
</set> 

slide_out_left

<?xml version="1.0" encoding="utf-8"?> 
<set xmlns:android="http://schemas.android.com/apk/res/android"> 
    <translate android:fromXDelta="0" android:toXDelta="-50%p" 
       android:duration="@android:integer/config_mediumAnimTime"/> 
    <alpha android:fromAlpha="1.0" android:toAlpha="0.0" 
      android:duration="@android:integer/config_mediumAnimTime" /> 
</set>
