我想使用适配器显示列表视图。我的问题是项目不是一个接一个地直接显示,而是每页一个(每两个项目之间有一个空格)。
这是代码
程序项适配器.java
public class ProgrammeItemAdapter extends BaseAdapter {
List<Programme> progs;
LayoutInflater inflater;
static class ProgrammeHolder {
TextView heure_deb;
TextView heure_fin ;
TextView nom ;
TextView genre ;
TextView duree ;
}
public ProgrammeItemAdapter(Context context,List<Programme> progs) {
inflater = LayoutInflater.from(context);
this.progs = progs;
}
public View getView(int position, View convertView, ViewGroup parent) {
ProgrammeHolder holder=null;
if(convertView == null) {
holder = new ProgrammeHolder();
convertView = inflater.inflate(R.layout.item_programme, null);
holder.heure_deb = (TextView) convertView.findViewById(R.id.heure_debut);
holder.heure_fin = (TextView) convertView.findViewById(R.id.heure_fin);
holder.nom = (TextView) convertView.findViewById(R.id.nom_programme);
holder.genre = (TextView) convertView.findViewById(R.id.genre_programme);
holder.duree = (TextView) convertView.findViewById(R.id.duree_programme);
convertView.setTag(holder);
} else {
holder = (ProgrammeHolder) convertView.getTag();
}
holder.heure_deb.setText(progs.get(position).getHeure_deb());
holder.heure_fin.setText(progs.get(position).getHeure_fin());
holder.nom.setText(progs.get(position).getNom());
holder.genre.setText(progs.get(position).getGenre());
holder.duree.setText(progs.get(position).getDuree());
return convertView;
}
public int getCount() {
// TODO Auto-generated method stub
return progs.size();
}
public Object getItem(int position) {
return progs.get(position);
}
public long getItemId(int position) {
return position;
}
}
程序活动.java
public class ProgrammeTvActivity extends Activity{
private ListView listView;
private ProgrammeItemAdapter adapter;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.programme_list);
listView = (ListView) findViewById(R.id.listview_programme);
List<Programme> m_programmes= new ArrayList<Programme>();
m_programmes=FillList();
adapter = new ProgrammeItemAdapter(this, m_programmes);
adapter.notifyDataSetChanged();
listView.setAdapter(adapter);
}
private List<Programme> FillList(){
List<Programme> m_programmes= new ArrayList<Programme>();
try{
// m_programmes.clear();
Programme p1 = new Programme("10:00-","11:00","programme1","série","60 mn");
Programme p2 = new Programme("11:05-","12:00","programme2","foot","55 mn");
/*p1.setHeure_deb("10:00");
p1.setHeure_fin("10:50");
p1.setNom("ddd");
p1.setGenre("serie");
p1.setDuree("50mn");*/
m_programmes.add(p1);
m_programmes.add(p2);
return m_programmes;
} catch (Exception e) {
Log.e("BACKGROUND_PROC", e.getMessage());
return (m_programmes);
}
}
