I am trying to implement ListView with Delete functionality to delete item from the listview. I am successful to delete but failed to refresh the listview after deletetion o
I have the solution:
If you want to delete a row from a list view clicking on the DELETE button of each of that row do this. Here you have an example of a custom adapter class with a name and a delete button. Every time you press the button the row is deleted
public class UserCustomAdapter extends ArrayAdapter{
Context context;
int layoutResourceId;
ArrayList data = new ArrayList();
public UserCustomAdapter(Context context, int layoutResourceId,ArrayList data) {
super(context, layoutResourceId, data);
this.layoutResourceId = layoutResourceId;
this.context = context;
this.data = data;
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
View row = convertView;
UserHolder holder = null;
if (row == null) {
LayoutInflater inflater = ((Activity) context).getLayoutInflater();
row = inflater.inflate(layoutResourceId, parent, false);
holder = new UserHolder();
holder.textName = (TextView) row.findViewById(R.id.textView1);
holder.btnDelete = (Button) row.findViewById(R.id.button2);
row.setTag(holder);
} else {
holder = (UserHolder) row.getTag();
}
User user = data.get(position);
holder.btnDelete.setTag(position);
holder.textName.setText(user.getName());
holder.btnDelete.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String pos = v.getTag().toString();
int _posicion = Integer.parseInt(pos);
data.remove(_posicion);
notifyDataSetChanged();
}
});
return row;
}
static class UserHolder {
TextView textName;
Button btnDelete;
}
}
