SetText dans TextSwitcher en utilisant BaseAdapter

Question

J'ai une mise en page avec ImageSwitcher, une galerie de thumnail et une TextSwitcher. Je voudrais que le TextSwitcher mette à jour le texte en fonction de la miniature sélectionnée. Je l'ai essayé d'utiliser un baseadapter mettre à jour le TextSwitcher de manière similaire à la façon dont l'ImageSwitcher met à jour les images dans le ImageView, mais je suis en cours d'exécution dans un mur ici. Toute aide serait très appréciée! Je vous remercie!

JAVA:

public class ImageSwitch1 extends Activity implements 
     AdapterView.OnItemSelectedListener, ViewSwitcher.ViewFactory { 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     requestWindowFeature(Window.FEATURE_NO_TITLE); 

     setContentView(R.layout.imageswitcher); 

     TextSwitcher mTextSwitcher = (TextSwitcher) findViewById(R.id.textSwitcher1); 
     mSwitcher = (ImageSwitcher) findViewById(R.id.switcher); 
     mSwitcher.setFactory(this); 
     mSwitcher.setInAnimation(AnimationUtils.loadAnimation(this, 
       android.R.anim.fade_in)); 
     mSwitcher.setOutAnimation(AnimationUtils.loadAnimation(this, 
       android.R.anim.fade_out)); 


     mTextSwitcher.setFactory(this);

       android.R.anim.fade_out)); 

     Gallery g = (Gallery) findViewById(R.id.gallery);

    private Integer[] mThumbIds = {

    private Integer[] mText = { 
     R.string.item1, R.string.item2, R.string.item3, R.string.item4, R.string.item5 
    }; 


} 

XML:

<?xml version="1.0" encoding="utf-8"?> 


    <FrameLayout android:id="@+id/FrameLayout1" android:layout_height="match_parent" xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent">

     <Gallery android:id="@+id/gallery"

     <TextSwitcher android:layout_width="match_parent" android:id="@+id/textSwitcher1" android:layout_height="wrap_content"></TextSwitcher> 

    </FrameLayout>

Vous devriez passer un chaîne à mTextSwitcher.setText(mThumbIds[position]);
changer la place à mTextSwitcher.setText(getText(mText[position]));
