public class FoodTypeAdapter extends BaseAdapter {
private Context context;
public FoodTypeAdapter(Context context) {
this.context = context;
}
public View getView(final int position, View convertView, ViewGroup parent) {
final ViewHolder holder = null;
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.food_type_grid,
new LinearLayout(context));
holder = new ViewHolder();
holder.btnAdd = (Button) convertView.findViewById(R.id.btnItemAdd);
holder.etQty = (EditText) convertView.findViewById(R.id.etfItemQty);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.btnAdd.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
String quantity = holder.etQty.getText().toString();
System.out.println(quantity);
}
});
return convertView;
}
public int getCount() {
return mylist.size();
}
public Object getItem(int position) {
return null;
}
public long getItemId(int position) {
return 0;
}
static class ViewHolder {
Button btnAdd;
EditText etQty;
}
}
In this code without make holder
as final
Object
I can't access it from OnClickListener
.
If I make it as final
Object
I can't initiate holder
like holder = new ViewHolder();
.
Now what can I do? Any help will be highly appreciable.
Thanks, Guna
You also could have simply adjusted the initialization of holder
which reduced your code complexity by the way:
final ViewHolder holder;
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.food_type_grid,
new LinearLayout(context));
holder = new ViewHolder();
holder.btnAdd = (Button) convertView.findViewById(R.id.btnItemAdd);
holder.etQty = (EditText) convertView.findViewById(R.id.etfItemQty);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
You can work around it by adding a temporary final
variable before the anonymous class, and use that variable instead:
final ViewHolder finalHolder = holder; // <- added
holder.btnAdd.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
String quantity = finalHolder.etQty.getText().toString();
// ^^^^^^^^^^^
System.out.println(quantity);
}
});
Or, you could make holder
a member variable.
