一、自定义listview的布局，首先是布局文件mylist.xml：

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

</RelativeLayout>

</LinearLayout>

------------------------------------------------------------------

二、其次是在自己定义的adapter中加载布局文件，并根据需要设置显示样子

public class NoticeAdapter extends BaseAdapter {

  private Context context ;
  private LayoutInflater listContainer;
  private Handler listHandler;

  public final class ListItemView{
   public TextView subject;
   public TextView info_type;
   public TextView insert_time;
   public TextView content;

  }

  public NoticeAdapter(Context context,Handler listHandler){
   this.context = context;
   this.listHandler = listHandler;
         listContainer = LayoutInflater.from(context);    //创建视图容器并设置上下文

  }

  @Override
  public int getCount() {
   // TODO Auto-generated method stub
   return listItems.size();
  }

  @Override
  public Object getItem(int arg0) {
   // TODO Auto-generated method stub
   return arg0;
  }

  @Override
  public long getItemId(int arg0) {
   // TODO Auto-generated method stub
   return arg0;
  }

      /**
       * 显示物品详情
       * @param clickID
       */
      private void showDetailInfo(int clickID) {
          new AlertDialog.Builder(context)
          .setTitle("公告详情：" + listItems.get(clickID).getSubject())
          .setMessage(listItems.get(clickID).getContent())
          .setPositiveButton("确定", null)
          .show();
      }



  @Override
  public View getView(int position, View convertView, ViewGroup parent) {
   // TODO Auto-generated method stub
           Log.v("method", "getView");

          //自定义视图
           ListItemView listItemView = null;
           if (convertView == null) {
              listItemView = new ListItemView();
              //获取list_item布局文件的视图
               convertView = listContainer.inflate(R.layout.mylist, null);
              //获取控件对象
               listItemView.info_type = (TextView)convertView.findViewById(R.id.info_type);
               listItemView.subject = (TextView)convertView.findViewById(R.id.subject);
               listItemView.insert_time = (TextView)convertView.findViewById(R.id.insert_time);
               listItemView.content= (TextView)convertView.findViewById(R.id.content);
               //设置控件集到convertView
               convertView.setTag(listItemView);
           }else {
               listItemView = (ListItemView)convertView.getTag();
           }
   //      Log.e("image", (String) listItems.get(position).get("title")); //测试
   //      Log.e("image", (String) listItems.get(position).get("info"));

           //设置文字和图片
           if (listItems.get(position).getStatus()==1) {
           listItemView.subject.setText(listItems.get(position).getSubject());
           //设置粗体与否
     }
           else {
           listItemView.subject.setText(listItems.get(position).getSubject());
           //设置粗体与否
     }

           if(listItems.get(position).getInfo_type().equals("1")){
           listItemView.info_type.setText("number1");
           listItemView.info_type.setTextColor(Color.rgb(67, 188, 38));
           }
           else {
           listItemView.info_type.setText("number2");
           listItemView.info_type.setTextColor(Color.rgb(255, 174, 0));
     }
           listItemView.insert_time.setText("time ");
           listItemView.content.setText("正文信息");

           return convertView;
  }

}

--------------------------------------------------------------------------------------------------

三、用listview设置dapter，并设置监听事件

NoticeAdapter noticeAdapter = new NoticeAdapter(this,listHandler);
itemsListView.setAdapter(noticeAdapter);

itemsListView.setOnItemClickListener(this);

private Handler listHandler = new Handler(){
public void handleMessage(Message msg) {
//在这个handler中要处理的事情，这个自己写啦
};
};

--------------------------------------------------------------------------------------------------

四、根据点击事情获取要处理的事情

public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
  System.out.println("点击位置"+arg2);
//这样就能获得listview中点击了那一项


   }
