扩展BaseAdapter可以对各列表项进行最大限度的定制，具体描述请看以下代码:
baseadapter_list布局文件：
<span style="font-size:18px;"><?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <ListView android:id="@+id/lv_baseadapter" android:layout_width="fill_parent" android:layout_height="wrap_content" > </ListView></LinearLayout></span>
baseadapter布局文件：
<span style="font-size:18px;"><?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" > <LinearLayout android:id="@+id/ll_top" android:layout_height="wrap_content" android:layout_width="fill_parent" android:orientation="horizontal"> <ImageView android:id="@+id/iv_image" android:layout_height="wrap_content" android:layout_width="wrap_content" android:scaleType="fitXY" android:src="@drawable/a5i" android:layout_gravity="center"/> <LinearLayout android:id="@+id/ll_right" android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="vertical" android:layout_marginTop="4dp"> <TextView android:id="@+id/tv_title" android:layout_height="wrap_content" android:layout_width="wrap_content" android:textSize="20sp" android:text="AS"/> <TextView android:id="@+id/tv_des" android:layout_height="wrap_content" android:layout_width="wrap_content" android:textSize="13sp" android:text="AS" /> </LinearLayout></LinearLayout></RelativeLayout></span>
BaseAdapterTest主文件：
<span style="font-size:18px;">public class BaseAdapterTest extends Activity { int[] images = new int[] { R.drawable.a5i, R.drawable.a5j, R.drawable.a5k }; String[] titles = new String[] { "电话", "QQ", "联系人" }; String[] des = new String[] { "当前无电话记录", "当前无QQ聊天记录", "最近无联系人" }; private ListView lv_baseadapter; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.baseadapter_list); initView(); setDate(); } private void initView(){ //注册控件 lv_baseadapter=(ListView)findViewById(R.id.lv_baseadapter); //注册单击事件 lv_baseadapter.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { Toast.makeText(BaseAdapterTest.this, "点击了第"+position+"项", Toast.LENGTH_SHORT).show(); } }); } private void setDate(){ //绑定适配器 lv_baseadapter.setAdapter(baseAdapter); } BaseAdapter baseAdapter=new BaseAdapter() { /* *返回第postion处的列表项组件 * @see android.widget.Adapter#getView(int, android.view.View, android.view.ViewGroup) */ @Override public View getView(int position, View convertView, ViewGroup parent) { ViewHolder viewHolder=new ViewHolder(); if(null==convertView){ LayoutInflater layoutInflater=LayoutInflater.from(BaseAdapterTest.this); convertView=layoutInflater.inflate(R.layout.baseadapter, null); viewHolder.iv_image=(ImageView)convertView.findViewById(R.id.iv_image); viewHolder.tv_title=(TextView)convertView.findViewById(R.id.tv_title); viewHolder.tv_desc=(TextView)convertView.findViewById(R.id.tv_des); /* * 将当前的View和ViewHolder绑定 */ convertView.setTag(viewHolder); }else{ /* * 为已经取得绑定的View调用getTag()方法，当前的view就不必重新绘制， * 减少内存资源。 */ viewHolder=(ViewHolder)convertView.getTag(); } viewHolder.iv_image.setImageResource(images[position]); viewHolder.tv_title.setText(titles[position]); viewHolder.tv_desc.setText(des[position]); return convertView; } /* * 返回第postion处的列表项的ID * @see android.widget.Adapter#getItemId(int) */ @Override public long getItemId(int position) { return position; } /* * 返回第postion处的列表项的内容。该方法在事件监听时会调用 * @see android.widget.Adapter#getItem(int) */ @Override public Object getItem(int position) { return position; } /* * 返回该Adapter将会包含多少个列表项 * @see android.widget.Adapter#getCount() */ @Override public int getCount() { return titles.length; } }; private class ViewHolder{ ImageView iv_image; TextView tv_title; TextView tv_desc; }}</span>
