I have a list view in my screen, every list item contains 2 text views and one button. On button click i want to take the list item selected index to get some data from a vector.
This is my List Custom Adapter.But i don't know how to do that.
private class CustomAdapter extends ArrayAdapter<ServicesItems> {
public CustomAdapter(Context context, int resource,
int textViewResourceId, List<ServicesItems> objects) {
super(context, resource, textViewResourceId, objects);
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder = null;
TextView item = null;
TextView description = null;
Button subNowBtn;
ServicesItems ii = getItem(position);
if (null == convertView) {
convertView = mInflater.inflate(
R.layout.list_of_servics_item_2, null);
holder = new ViewHolder(convertView);
convertView.setTag(holder);
}
holder = (ViewHolder) convertView.getTag();
// cat_name = holder.gettitle();
Resources resources = getResources();
ServicesItems bean1 = (ServicesItems) servicesVector
.elementAt(position);
String cat_name_str = bean1.getService_name().toString();
String descreption = bean1.getDescription().toString();
item = holder.getItem();
item.setText(bean1.getDescription());
description = holder.getDescription();
description.setText(bean1.getService_name());
subNowBtn=holder.getSubButton();
return convertView;
}
private class ViewHolder {
private View mRow;
private TextView description = null;
private TextView item = null;
private Button sub = null;
public ViewHolder(View row) {
mRow = row;
}
public TextView getDescription() {
if (null == description) {
description = (TextView) mRow
.findViewById(R.id.category_tv);
}
return description;
}
public TextView getItem() {
if (null == item) {
item = (TextView)
mRow.findViewById(R.id.descreption_tv);
}
return item;
}
public Button getSubButton(){
if(null==sub){
sub=(Button)findViewById(R.id.subscribe_now_btn);
}
return sub;
}
}
}
In your Adapter try this:
@Override
public View getView(final int position, View convertView, ViewGroup parent)
{
View row = convertView;
YourWrapper wrapper = null;
if (row == null)
{
row = inflater.inflate(R.layout.layout, parent, false);
wrapper = new YourWrapper (row);
row.setTag(wrapper);
}
else
wrapper = (YourWrapper) row.getTag();
wrapper.getButton().setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v)
{
// What you want
}
});
return row;
}
EDIT
Your wrapper class:
public class YourWrapper
{
private View base;
private Button button;
public YourWrapper(View base)
{
this.base = base;
}
public Button getButton()
{
if (button == null)
{
button = (Button) base.findViewById(R.id.your_button);
}
return (button`);
}
}
Change sub=(Button)findViewById(R.id.subscribe_now_btn);
into sub=(Button) mRow.findViewById(R.id.subscribe_now_btn);
