Android 自定义ListView + Gallery 结合

效果如图:  Item项包含标题、描述及一个Gallery.

    主配置文件(main):

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"	android:orientation="vertical" android:layout_width="fill_parent"	android:layout_height="fill_parent">	<!-- 解决ListView拖拽背景图片的bug: ListView中加入android:cacheColorHint="#00000000" -->	<!-- 给ListView每一项添加分隔线:android:divider="@color/snow" android:dividerHeight="1dip" -->	<ListView android:id="@+id/my_lst" android:layout_width="fill_parent"		android:layout_height="fill_parent" android:background="@drawable/bac"		android:divider="@color/snow" android:dividerHeight="1dip"		android:cacheColorHint="#00000000">	</ListView></LinearLayout>

    ListView 的Item配置文件(items):

<?xml version="1.0" encoding="utf-8"?><RelativeLayout android:id="@+id/items"	xmlns:android="http://schemas.android.com/apk/res/android"	android:orientation="vertical" android:layout_width="fill_parent"	android:layout_height="fill_parent">	<TextView android:id="@+id/item_title" android:layout_width="wrap_content"		android:textSize="20dip" android:layout_height="wrap_content"		android:textColor="@color/snow" android:layout_marginLeft="10dip"		android:layout_alignParentLeft="true" android:gravity="bottom" />	<TextView android:id="@+id/item_describe" android:textColor="@color/snow"		android:layout_width="wrap_content" android:textSize="15dip"		android:layout_marginTop="5dip" android:layout_height="wrap_content"		android:layout_marginLeft="20dip" android:layout_toRightOf="@+id/item_title"		android:gravity="bottom" />	<!-- 设置Gallery每一项的间距:android:spacing="10dip" -->	<Gallery android:id="@+id/item_gallery" android:layout_width="fill_parent"		android:layout_height="wrap_content" android:spacing="10dip"		android:layout_below="@+id/item_title" android:layout_marginTop="20dip"		android:layout_marginBottom="20dip" /></RelativeLayout>

values文件夹下colors.xml:

<?xml version="1.0" encoding="utf-8"?><resources>	<color name="white">#ffffff</color><!--白色 -->	<color name="snow">#fffafa</color><!--雪白色 -->	<color name="silver">#c0c0c0</color><!--银色 -->	<color name="blue">#0000FF</color><!-- 蓝色 -->	<color name="skyblue">#87ceeb</color><!--天蓝色 -->  	<color name="darkgrey">#a9a9a9</color><!--暗灰色 -->  </resources>

JavaBean(ListItem),对应到每一项ListView的item项:

package com.march.view;import java.io.InputStream;import android.content.Context;import android.graphics.Bitmap;import android.graphics.BitmapFactory;import android.graphics.BitmapFactory.Options;import android.view.View;import android.view.ViewGroup;import android.widget.BaseAdapter;import android.widget.ImageView;public class ListItem {	public String title, describe;	public int[] itemImages;	public ImageAdapter adapter;	public void initAdapter(Context context) {		this.adapter = new ImageAdapter(context);	}	public class ImageAdapter extends BaseAdapter {		private Context mContext;		public ImageAdapter(Context context) {			this.mContext = context;		}		@Override		public int getCount() {			// TODO Auto-generated method stub			return Integer.MAX_VALUE;		}		@Override		public Object getItem(int i) {			// TODO Auto-generated method stub			return i;		}		@Override		public long getItemId(int i) {			// TODO Auto-generated method stub			return i;		}		@Override		public View getView(int i, View view, ViewGroup viewgroup) {			view = new ImageView(mContext);			((ImageView) view).setImageBitmap(ListItem.readBitmap(mContext,					itemImages[i % itemImages.length]));			return view;		}	}	/***	 * 以最省内存的方式读取本地资源的图片	 * 	 * @param context	 * @param resId	 * @return	 */	public static Bitmap readBitmap(Context context, int rid) {		BitmapFactory.Options options = new BitmapFactory.Options();		options.inPreferredConfig = Bitmap.Config.RGB_565;		options.inPurgeable = true;		options.inInputShareable = true;		// 获取资源图片		InputStream is = context.getResources().openRawResource(rid);		return BitmapFactory.decodeStream(is, null, options);	}}
