Question

Je suis en train d'obtenir imbriqués viewflippers mis en place avec la configuration suivante

Top_ViewFlipper

    - SubType 1 
    - SubType 2 
    - SubType 3 
- Type 2 
    Sub_ViewFlipper 
    - SubType 1 
    - SubType 2 
    - SubType 3

Actuellement, il seulement les erreurs dues, deux commits avant que j'avais une primaire Viewflipper fonctionne, mais l'imbriquer semble s d'avoir des choses cassées ... même après avoir ajouté manuellement des vues de liste au viewflipper imbriqué (au lieu d'utiliser une méthode générique). Je n'arrive pas à assigner les sous-types au subViewflipper approprié. Quelqu'un at-il un exemple de ce soit XML ou par programme? Je n'ai pas encore trouvé d'exemples sur l'utilisation de viewflippers imbriqués. En option, l'hôte de l'onglet peut fonctionner, mais je préférerais les boutons en mode texte et j'aime les animations fournies avec viewflipper.

D'accord, ce sera une grande réponse ... mais j'espère que c'est ce que vous recherchez.

L'activité:

private GestureDetector gestureScanner; 
private ViewFlipper rootFlipper; 
private ViewFlipper flipper1, flipper2; 

private Animation animFlipInNext, animFlipOutNext; 
private Animation animFlipInPrevious, animFlipOutPrevious; 
private Animation rootAnimFlipInNext, rootAnimFlipOutNext; 
private Animation rootAnimFlipInPrevious, rootAnimFlipOutPrevious; 

/** Called when the activity is first created. */ 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 

    // Root flipper 
    rootFlipper = (ViewFlipper) findViewById(R.id.rootFlipper); 

    // Content flippers 
    flipper1 = (ViewFlipper) findViewById(R.id.viewFlipper1); 
    flipper2 = (ViewFlipper) findViewById(R.id.viewFlipper2); 

    gestureScanner = new GestureDetector(this); 

    // Animations 
    animFlipInNext = AnimationUtils.loadAnimation(this, R.anim.flipinnext); 
    animFlipOutNext = AnimationUtils.loadAnimation(this, R.anim.flipoutnext); 
    animFlipInPrevious = AnimationUtils.loadAnimation(this, 
      R.anim.flipinprevious); 
    animFlipOutPrevious = AnimationUtils.loadAnimation(this, 
      R.anim.flipoutprevious); 

    rootAnimFlipInNext = AnimationUtils.loadAnimation(this, 
      R.anim.rootflipinnext); 
    rootAnimFlipOutNext = AnimationUtils.loadAnimation(this, 
      R.anim.rootflipoutnext); 
    rootAnimFlipInPrevious = AnimationUtils.loadAnimation(this, 
      R.anim.rootflipinprevious); 
    rootAnimFlipOutPrevious = AnimationUtils.loadAnimation(this, 
      R.anim.rootflipoutprevious); 
} 
    @Override 
public boolean onTouchEvent(MotionEvent event) { 
    return gestureScanner.onTouchEvent(event); 
} 

@Override 
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, 
     float velocityY) { 

    Log.i("TEST", "Fling!!"); 

    if (Math.abs(velocityY) > Math.abs(velocityX)) { 
     if (velocityY > 0) { 
      rootFlipper.setInAnimation(rootAnimFlipInNext); 
      rootFlipper.setOutAnimation(rootAnimFlipOutNext); 
      rootFlipper.showNext(); 
     } else if (velocityY < 0) { 
      rootFlipper.setInAnimation(rootAnimFlipInPrevious); 
      rootFlipper.setOutAnimation(rootAnimFlipOutPrevious); 
      rootFlipper.showPrevious(); 
     } 
    } else { 
     if (velocityX > 0) { 
      ViewFlipper v = (ViewFlipper) rootFlipper.getCurrentView(); 
      v.setInAnimation(animFlipInNext); 
      v.setOutAnimation(animFlipOutNext); 
      v.showNext(); 
     } else if (velocityX < 0) { 
      ViewFlipper v = (ViewFlipper) rootFlipper.getCurrentView(); 
      v.setInAnimation(animFlipInPrevious); 
      v.setOutAnimation(animFlipOutPrevious); 
      v.showPrevious(); 
     } 
    } 
    return true; 
}

Les animations:

flipinnext.xml

<?xml version="1.0" encoding="utf-8"?> 
<set xmlns:android="http://schemas.android.com/apk/res/android" 
android:interpolator="@android:anim/decelerate_interpolator" > 
<translate 
    android:duration="500" 
    android:fromXDelta="-100%" 
    android:toXDelta="0%" /> 
</set> 

flipinprevious.xml

<?xml version="1.0" encoding="utf-8"?> 
<set xmlns:android="http://schemas.android.com/apk/res/android" 
android:interpolator="@android:anim/decelerate_interpolator" > 
<translate 
    android:duration="500" 
    android:fromXDelta="100%" 
    android:toXDelta="0%" /> 
</set> 

flipoutnext.xml

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

<translate 
    android:duration="500" 
    android:fromXDelta="0%" 
    android:toXDelta="100%" /> 

</set> 

flipoutprevious.xml

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

<translate 
    android:duration="500" 
    android:fromXDelta="0%" 
    android:toXDelta="-100%" /> 

</set> 

Et vous avez besoin d'un ensemble d'animations presque identiques pour le flip racine (axe y). Copiez simplement les animations de l'axe des x et changez les attributs de translation en axe Y.
