Java 带有BaseLayout的ListView仅显示第一项

我正在尝试创建BaseAdapter并将其设置为ListView的适配器

每个元素在适配器中都包含一个按钮和一个文本

这是扩展BaseAdapter的my Components Adapter：

package com.tuxin.myalcoholist;

import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.Button;
import android.widget.TextView;

import java.util.ArrayList;
import java.util.Collections;
import java.util.List;

public class IngredientsAdapter extends BaseAdapter {

private List<String> ingredients = new ArrayList<String>();

private final Context context;

public List<String> getItems() {
    return this.ingredients;
}

public void add(final String value) {
    ingredients.add(value);
    notifyDataSetChanged();
}

public IngredientsAdapter(Context context) {
    this.context=context;
}

public void updateIngredients(List<String> ingredients) {
    this.ingredients=ingredients;
    notifyDataSetChanged();
}



@Override
public int getCount() {
    return this.ingredients.size();
}

@Override
public String getItem(int position) {
    return ingredients.get(position);
}

@Override
public long getItemId(int position) {
    return position;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    if (convertView == null) {
        convertView = LayoutInflater.from(context)
                .inflate(R.layout.ingredient_item,parent,false);
    }
    Button button = (Button)convertView.findViewById(R.id.ingredient_button);
    TextView textView = (TextView)convertView.findViewById(R.id.ingredient_textView);
    final String ingredient = this.getItem(position);
    textView.setText(ingredient);
    return convertView;
}
}
