Bonjour.

J'essaie d'apprendre les différents type de vues, et en particulier Gridview.

Le guide Android propose un exemple : http://developer.android.com/guide/topics/ui/layout/gridview.html

Que voici :

<?xml version="1.0" encoding="utf-8"?>
<GridViewxmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/gridview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:columnWidth="90dp"
android:numColumns="auto_fit"
android:verticalSpacing="10dp"
android:horizontalSpacing="10dp"
android:stretchMode="columnWidth"
android:gravity="center"
/>

publicvoid onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
GridView gridview =(GridView) findViewById(R.id.gridview);
gridview.setAdapter(newImageAdapter(this));
gridview.setOnItemClickListener(newOnItemClickListener(){
publicvoid onItemClick(AdapterView<?> parent,View v,int position,long id){
Toast.makeText(HelloGridView.this,""+ position,Toast.LENGTH_SHORT).show();
}
});
}

publicclassImageAdapterextendsBaseAdapter{
privateContext mContext;
publicImageAdapter(Context c){
mContext = c;
}
publicint getCount(){
return mThumbIds.length;
}
publicObject getItem(int position){
returnnull;
}
publiclong getItemId(int position){
return0;
}
// create a new ImageView for each item referenced by the Adapter
publicView getView(int position,View convertView,ViewGroup parent){
ImageView imageView;
if(convertView ==null){// if it's not recycled, initialize some attributes
imageView =newImageView(mContext);
imageView.setLayoutParams(newGridView.LayoutParams(85,85));
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
imageView.setPadding(8,8,8,8);
}else{
imageView =(ImageView) convertView;
}
imageView.setImageResource(mThumbIds[position]);
return imageView;
}
// references to our images
privateInteger[] mThumbIds ={
R.drawable.sample_2, R.drawable.sample_3,
R.drawable.sample_4, R.drawable.sample_5,
R.drawable.sample_6, R.drawable.sample_7,
R.drawable.sample_0, R.drawable.sample_1,
R.drawable.sample_2, R.drawable.sample_3,
R.drawable.sample_4, R.drawable.sample_5,
R.drawable.sample_6, R.drawable.sample_7,
R.drawable.sample_0, R.drawable.sample_1,
R.drawable.sample_2, R.drawable.sample_3,
R.drawable.sample_4, R.drawable.sample_5,
R.drawable.sample_6, R.drawable.sample_7
};
}

Ça marche avec les images. Mais je voudrais non pas mettre des images, mais du texte, ou des boutons, et dans ce cas, j'ai bien l'affichage, mais je ne peux pas interagir, et savoir quel texte ou bouton a été touché ou cliqué :

apparemment

gridview.setOnItemClickListener(newOnItemClickListener(){
publicvoid onItemClick(AdapterView<?> parent,View v,int position,long id){
Toast.makeText(HelloGridView.this,""+ position,Toast.LENGTH_SHORT).show();

ne réagit pas.

N'ayant vu aucune raison dans le guide Android, je tourne en rond.

Quelqu'un aurai une idée, ou une explication si c'est impossible.

Merci.
