Android 自定义ListView + Gallery 组合
效果如图: Item项包含标题、描述及一个Gallery.
主配置文件(main):
[html]
<?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):
[java]
<?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:
[html]
<?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:
[java]
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 % itemIm
