我想custom adapter为我的列表视图创建一个。是否有任何文章可以引导我逐步创建并解释其工作原理？

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课程。您需要收藏要显示的商品，在我的情况下是<Item>。您需要重写View getView(int position, View convertView, ViewGroup parent)方法。

R.layout.itemlistrow定义的行ListView。

<?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">

                  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>

在这样的MainActivity定义中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);

我知道已经回答了……但是我想举一个更完整的例子。

在我的示例中，ListActivity将显示我们的自定义ListView的称为OptionsActivity，因为在我的项目中这Activity将显示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，一种列表项类型只有一个TextView，而另一种列表项只有一个Button。您可以在每个列表项类型中放入所需的任何小部件，但我使此示例保持简单。

该getItemView()方法检查哪些列表项应为类型1或类型2。根据我在顶部定义的静态整数，前5个列表项将为列表项类型1，最后5个列表项将为列表项类型2。 。因此，如果编译并运行它，则将有一个ListView包含五个仅包含a的Button项，然后包含五个仅包含a的项TextView。

下面是Activity代码，活动xml文件和每种列表项类型的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;
    }

Google有一个名为EfficientAdapter的示例，我认为这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对上述示例http：//中使用的模式进行了很好的解释 commonsware.com/Android/excerpt.pdf

您可以在官方的ApiDemos中查看此示例。它显示了如何扩展BaseAdapter并将其应用于ListView。之后，只需查看参考资料BaseAdapter并尝试了解每种方法的功能（包括继承的方法）以及何时/如何使用它。

另外，Google是您的朋友:)。

通过非常简单地检查该链接，convertView我们可以获取将在listview中显示的行的布局（即parentView）。

View v = convertView;

if (v == null) {

    LayoutInflater vi;
    vi = LayoutInflater.from(getContext());
    v = vi.inflate(R.layout.itemlistrow, null);

}

使用该位置，您可以获取的对象List<Item>。

Item p = items.get(position);

之后，我们必须将对象的所需详细信息设置为已标识的表单小部件。

if (p != null) {

    TextView tt = (TextView) v.findViewById(R.id.id);
    TextView tt1 = (TextView) v.findViewById(R.id.categoryId);
    TextView tt3 = (TextView) v.findViewById(R.id.description);

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

        tt1.setText(p.getCategory().getId());
    }
    if (tt3 != null) {

        tt3.setText(p.getDescription());
    }
}

然后它将返回构造视图，该视图将附加到上parentView（是ListView/ GridView）。

这是逐步为列表视图创建自定义适配器的完整演练-

自定义适配器的一个更紧凑的示例（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;
    }
}

这是如何使用它：

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

BaseAdapter 是用于listview的最佳自定义适配器。

Class MyAdapter extends BaseAdapter{}

并且它有许多功能，例如getCount()，getView()等

这很简单。
