下面是逐步为列表视图创建自定义适配器的完整步骤

https://www.caveofprogramming.com/guest-posts/custom-listview-with-imageview-and-textview-in-android.html

public class CustomAdapter extends BaseAdapter{   
    String [] result;
    Context context;
 int [] imageId;
      private static LayoutInflater inflater=null;
    public CustomAdapter(MainActivity mainActivity, String[] prgmNameList, int[] prgmImages) {
        // TODO Auto-generated constructor stub
        result=prgmNameList;
        context=mainActivity;
        imageId=prgmImages;
         inflater = ( LayoutInflater )context.
                 getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    }
    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return result.length;
    }

    @Override
    public Object getItem(int position) {
        // TODO Auto-generated method stub
        return position;
    }

    @Override
    public long getItemId(int position) {
        // TODO Auto-generated method stub
        return position;
    }

    public class Holder
    {
        TextView tv;
        ImageView img;
    }
    @Override
    public View getView(final int position, View convertView, ViewGroup parent) {
        // TODO Auto-generated method stub
        Holder holder=new Holder();
        View rowView;       
             rowView = inflater.inflate(R.layout.program_list, null);
             holder.tv=(TextView) rowView.findViewById(R.id.textView1);
             holder.img=(ImageView) rowView.findViewById(R.id.imageView1);       
         holder.tv.setText(result[position]);
         holder.img.setImageResource(imageId[position]);         
         rowView.setOnClickListener(new OnClickListener() {            
            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                Toast.makeText(context, "You Clicked "+result[position], Toast.LENGTH_LONG).show();
            }
        });   
        return rowView;
    }

} 

public class ListAdapter extends ArrayAdapter<Item> {

    private int resourceLayout;
    private Context mContext;

    public ListAdapter(Context context, int resource, List<Item> items) {
        super(context, resource, items);
        this.resourceLayout = resource;
        this.mContext = context;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {

        View v = convertView;

        if (v == null) {
            LayoutInflater vi;
            vi = LayoutInflater.from(mContext);
            v = vi.inflate(resourceLayout, null);
        }

        Item p = getItem(position);

        if (p != null) {
            TextView tt1 = (TextView) v.findViewById(R.id.id);
            TextView tt2 = (TextView) v.findViewById(R.id.categoryId);
            TextView tt3 = (TextView) v.findViewById(R.id.description);

            if (tt1 != null) {
                tt1.setText(p.getId());
            }

            if (tt2 != null) {
                tt2.setText(p.getCategory().getId());
            }

            if (tt3 != null) {
                tt3.setText(p.getDescription());
            }
        }

        return v;
    }

}

这是我在项目中使用的一个类。你需要有一个你想要显示的项目的集合，在我的例子中是<Item>。你需要重写View getView(int position, View convertView, ViewGroup parent)方法。

itemlistrow定义了ListView的行。

<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_height="wrap_content" android:orientation="vertical"
    android:layout_width="fill_parent">

    <TableRow android:layout_width="fill_parent"
              android:id="@+id/TableRow01"
              android:layout_height="wrap_content">

        <TextView android:textColor="#FFFFFF"
                  android:id="@+id/id"
                  android:layout_width="fill_parent"
                  android:layout_height="wrap_content"
                  android:text="id" android:textStyle="bold" 
                  android:gravity="left"
                  android:layout_weight="1" 
                  android:typeface="monospace"
                  android:height="40sp" />
    </TableRow>

    <TableRow android:layout_height="wrap_content"
              android:layout_width="fill_parent">

        <TextView android:textColor="#FFFFFF" 
                  android:id="@+id/categoryId"
                  android:layout_width="fill_parent"
                  android:layout_height="wrap_content"
                  android:text="categoryId" 
                  android:layout_weight="1" 
                  android:height="20sp" />

        <TextView android:layout_height="wrap_content"
                  android:layout_width="fill_parent" 
                  android:layout_weight="1"
                  android:textColor="#FFFFFF"
                  android:gravity="right"
                  android:id="@+id/description"
                  android:text="description" 
                  android:height="20sp" />
    </TableRow>

</TableLayout>

在MainActivity中定义listview，

ListView yourListView = (ListView) findViewById(R.id.itemListView);

// get data from the table by the ListAdapter
ListAdapter customAdapter = new ListAdapter(this, R.layout.itemlistrow, List<yourItem>);

yourListView .setAdapter(customAdapter);

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。

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

这很简单。
