You need not make ArrayList
static.
You need to delete the data from the list which populates listview. You call notifyDataSetChanged();
to refresh the lsitview.
You can remove the static key word and use
Button b2 = (Button) row.findViewById(R.id.button1);
b2.setTag(arg0);
b2.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
int pos = (int)arg0.getTag();
lista.remove(pos);
SunetePreferateAdaptor.this.notifyDataSetChanged(); }
});
Alternative :
You can pass the list to the constructor of adapter class.
ListView lv = (ListView) this.findViewById(R.id.listView1);
ArrayList<ob> lista = new ArrayList<ob>();
for (int i = 1; i <= 20; i++) {
lista.add(new ob("text", "text"+i));
}
lv.setAdapter(new SunetePreferateAdaptor(this,lista));
Then have this in a separate .java file
class ob {
String titlu, descriere;
public ob(String titlu, String descriere) {
this.titlu = titlu;
this.descriere = descriere;
}
}
Then
public class SunetePreferateAdaptor extends BaseAdapter {
ArrayList<ob> lista;
Context context;
public SunetePreferateAdaptor(Context context, ArrayList<ob> lista ) {
this.context = context;
this.lista= lista;
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return lista.size();
}
@Override
public Object getItem(int arg0) {
// TODO Auto-generated method stub
return lista.get(arg0);
}
@Override
public long getItemId(int arg0) {
// TODO Auto-generated method stub
return arg0;
}
@Override
public View getView(int arg0, View arg1, ViewGroup arg2) {
// TODO Auto-generated method stub
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View row = inflater.inflate(R.layout.fg, arg2, false);
Button b2 = (Button) row.findViewById(R.id.button1);
b2.setTag(arg0);
b2.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
int pos = (int)arg0.getTag();
lista.remove(pos);
SunetePreferateAdaptor.this.notifyDataSetChanged(); }
});
TextView titlu = (TextView) row.findViewById(R.id.textView1);
titlu.setText(lista.get(arg0).titlu);
titlu.setTextColor(Color.WHITE);
TextView descriere = (TextView) row.findViewById(R.id.textView2);
descriere.setText(lista.get(arg0).descriere);
return row;
}
}
