我知道这个问题已经有人回答了……但我想给出一个更完整的例子。

在我的例子中，ListActivity将显示我们的自定义ListView被称为OptionsActivity，因为在我的项目中，这个活动将显示我的用户可以设置来控制我的应用程序的不同选项。有两种列表项类型，一种列表项类型只是有一个TextView和第二个列表项类型只是有一个按钮。您可以在每个列表项类型中放入任何您喜欢的小部件，但是我保持这个示例的简单性。

getItemView()方法检查哪些列表项应该是类型1或类型2。根据我在上面定义的静态整数，前5个列表项将是列表项类型1，后5个列表项将是列表项类型2。如果你编译并运行这个，你会有一个ListView，它有五个项目，只包含一个按钮，然后五个项目，只包含一个TextView。

下面是活动代码、活动xml文件和每个列表项类型的xml文件。

OptionsActivity.java:

public class OptionsActivity extends ListActivity {

    private static final int LIST_ITEM_TYPE_1 = 0;
    private static final int LIST_ITEM_TYPE_2 = 1;
    private static final int LIST_ITEM_TYPE_COUNT = 2;

    private static final int LIST_ITEM_COUNT = 10;
    // The first five list items will be list item type 1 
    // and the last five will be list item type 2
    private static final int LIST_ITEM_TYPE_1_COUNT = 5;

    private MyCustomAdapter mAdapter;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        mAdapter = new MyCustomAdapter();
        for (int i = 0; i < LIST_ITEM_COUNT; i++) {
          if (i < LIST_ITEM_TYPE_1_COUNT)
            mAdapter.addItem("item type 1");
          else
            mAdapter.addItem("item type 2");
        }
        setListAdapter(mAdapter);
    }

    private class MyCustomAdapter extends BaseAdapter {

        private ArrayList<String> mData = new ArrayList<String>();
        private LayoutInflater mInflater;

        public MyCustomAdapter() {
            mInflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        }

        public void addItem(final String item) {
            mData.add(item);
            notifyDataSetChanged();
        }

        @Override
        public int getItemViewType(int position) {
          if(position < LIST_ITEM_TYPE_1_COUNT)
              return LIST_ITEM_TYPE_1;
          else
              return LIST_ITEM_TYPE_2;
        }

        @Override
        public int getViewTypeCount() {
            return LIST_ITEM_TYPE_COUNT;
        }

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

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

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

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            ViewHolder holder = null;
            int type = getItemViewType(position);
            if (convertView == null) {
                holder = new ViewHolder();
                switch(type) {
                    case LIST_ITEM_TYPE_1:
                        convertView = mInflater.inflate(R.layout.list_item_type1, null);
                        holder.textView = (TextView)convertView.findViewById(R.id.list_item_type1_text_view);
                        break;
                    case LIST_ITEM_TYPE_2:
                        convertView = mInflater.inflate(R.layout.list_item_type2, null);
                        holder.textView = (TextView)convertView.findViewById(R.id.list_item_type2_button);
                        break;
                }
                convertView.setTag(holder);
            } else {
                holder = (ViewHolder)convertView.getTag();
            }
            holder.textView.setText(mData.get(position));
            return convertView;
        }

    }

    public static class ViewHolder {
        public TextView textView;
    }

}

BaseAdapter是listview最好的自定义适配器。

Class MyAdapter extends BaseAdapter{}

它有许多函数，如getCount()， getView()等。

import android.app.Activity;

import android.content.Context;

import android.text.Html;

import android.view.LayoutInflater;

import android.view.View;

import android.view.ViewGroup;

import android.widget.BaseAdapter;

import android.widget.ImageView;

import android.widget.TextView;

import org.json.JSONObject;

import java.util.ArrayList;

public class OurteamAdapter extends BaseAdapter {

    Context cont;
    ArrayList<OurteamModel> llist;
    OurteamAdapter madap;
    LayoutInflater inflater;
    JsonHelper Jobj;
    String Id;
    JSONObject obj = null;
    int position = 0;
    public OurteamAdapter(Context c,ArrayList<OurteamModel> Mi)
    {
        this.cont = c;
        this.llist = Mi;
    }
    @Override
    public int getCount()
    {
        // TODO Auto-generated method stub
        return llist.size();
    }
    @Override
    public Object getItem(int position) {
        // TODO Auto-generated method stub
        return llist.get(position);
    }
    @Override
    public long getItemId(int position) {
        // TODO Auto-generated method stub
        return position;
    }
    @Override
    public View getView(final int position, View convertView, ViewGroup parent)
    {
        // TODO Auto-generated method stub
        if(convertView == null)
        {
            LayoutInflater in = (LayoutInflater) cont.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
            convertView = in.inflate(R.layout.doctorlist, null);
        }
        TextView category = (TextView) convertView.findViewById(R.id.button1);
        TextView title = (TextView) convertView.findViewById(R.id.button2);
        ImageView i1=(ImageView) convertView.findViewById(R.id.imageView1);
        category.setText(Html.fromHtml(llist.get(position).getGalleryName()));
        title.setText(Html.fromHtml(llist.get(position).getGalleryDetail()));
        if(llist.get(position).getImagesrc()!=null)
        {
            i1.setImageBitmap(llist.get(position).getImagesrc());
        }
        else
        {
            i1.setImageResource(R.drawable.anandlogo);
        }
        return convertView;
    }

}

您可以在官方ApiDemos中查看这个示例。它展示了如何扩展BaseAdapter并将其应用到ListView。在此之后，只需查看BaseAdapter的引用，并尝试理解每个方法做什么(包括继承的方法)以及何时/如何使用它。

另外，谷歌是你的朋友:)。

谷歌有一个名为EfficientAdapter的示例，在我看来，它是如何实现自定义适配器的最佳简单示例。http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/view/List14.html @CommonsWare很好地解释了上面例子中使用的模式 http://commonsware.com/Android/excerpt.pdf

一个更紧凑的自定义适配器的例子(使用列表数组作为我的数据):

class MyAdapter extends ArrayAdapter<Object> {
    public ArrayAdapter(Context context, List<MyObject> objectList) {
        super(context, R.layout.my_list_item, R.id.textViewTitle, objectList.toArray());
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View row = super.getView(position, convertView, parent);
        TextView title = (TextView) row.findViewById(R.id.textViewTitle);
        ImageView icon = (ImageView) row.findViewById(R.id.imageViewAccessory);
        MyObject obj = (MyObject) getItem(position);
        icon.setImageBitmap( ... );
        title.setText(obj.name);
        return row;
    }
}

下面是如何使用它:

List<MyObject> objectList = ...
MyAdapter adapter = new MyAdapter(this.getActivity(), objectList);
listView.setAdapter(adapter);
