Hier ist der Code für die Adapterklasse < /p>

package com.android.main;

import java.util.ArrayList;

import android.app.Activity;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.TextView;

public class DrinkAdapter extends ArrayAdapter
{
private Activity context;
ArrayList data = null;

public DrinkAdapter(Activity context, int resource, ArrayList data)
{
super(context, resource, data);
this.context = context;
this.data = data;
}

@Override
public View getView(int position, View convertView, ViewGroup parent)
{   // Ordinary view in Spinner, we use android.R.layout.simple_spinner_item
return super.getView(position, convertView, parent);
}

@Override
public View getDropDownView(int position, View convertView, ViewGroup parent)
{   // This view starts when we click the spinner.
View row = convertView;
if(row == null)
{
LayoutInflater inflater = context.getLayoutInflater();
row = inflater.inflate(R.layout.dropdown_value_id, parent, false);
}

Drink item = data.get(position);
String test = item.getName();
Log.d("test ", test);

if(item != null)
{

TextView drinkName = (TextView) row.findViewById(R.id.item_value);

if(drinkName != null){
drinkName.setText(item.getName());
Log.d("find me ", drinkName.toString());
}

}

return row;
}
}

Hier ist das XML für Dropdown_Value_id -Layout, das im Adapter verwendet wird.  < /p>
