ListView的数据绑定与点击事件读取信息

ListView 页面：

    <ListView
        android:id="@+id/listView1"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_alignParentLeft="true"
        android:layout_below="@+id/textId" >
    </ListView>

模板界面（及每行显示的内容为）：

  <TextView
        android:id="@+id/textName"
        android:layout_width="120dp"
        android:layout_height="wrap_content"
        android:textSize="17px"
        android:text="姓 名" />

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical" >

    </LinearLayout>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content" >

        <TextView
            android:id="@+id/textPhone"
            android:layout_width="234dp"
            android:layout_height="wrap_content"
            android:text="电话号"
            android:textSize="15px" />

        <TextView
            android:id="@+id/textId"
            android:layout_width="90dp"
            android:layout_height="wrap_content"
            android:text="序号" />

    </LinearLayout>

最后程序样式：

必须的变量：

 private personservice ps;    //数据操作对象（增删改查）
 private ListView listView;   //列表框对象
 List<person> listper;  //在方法一种用于装置数据，点击事件后取得所选行全部对象；

初始化数据信息：

ps=new personservice(this);  //数据实现部分参考ＳＱＬｉｔｅ的操作部分
listView=(ListView) this.findViewById(R.id.listView1);　//列表框

方法一、SimpleAdapter方式绑定数据：

 

	private void show() {
		listper=ps.getPage(0, 100);
		List<HashMap<String, Object>> data=new ArrayList<HashMap<String, Object>>();
		for(person p :listper)
		{
			HashMap<String, Object> item =new HashMap<String, Object>();
			item.put("id", "【"+p.getId()+"】");
			item.put("name", p.getName());
			item.put("phone", p.getPhone());
			data.add(item);
		}
		SimpleAdapter adapter=new SimpleAdapter(this, data,R.layout.item,
				new String[]{"id","name","phone"}, new int[]{R.id.textId,R.id.textName,R.id.textPhone});
		listView.setAdapter(adapter);
		listView.setOnItemClickListener(new ItemClickListener());
	}

	private final class ItemClickListener implements OnItemClickListener{
		@Override
		public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,long arg3) {
			// TODO Auto-generated method stub
		Toast.makeText(getApplicationContext(), listper.get(arg2).getName()+":"+listper.get(arg2).getPhone(), 1).show();
	}
	}

方法二、SimpleCursorAdapter方式绑定数据：

	private void show2(){
		Cursor cursor=ps.getPageCursor(0, 100);
		SimpleCursorAdapter adapter=new SimpleCursorAdapter(this, R.layout.item,cursor, new String[]{"_id","name","phone"},new int[]{R.id.textId ,R.id.textName,R.id.textPhone});
		listView.setAdapter(adapter);
		listView.setOnItemClickListener(new ItemClickListener2());
	}
	private final class ItemClickListener2 implements OnItemClickListener{

		@Override
		public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
				long arg3) {
			// TODO Auto-generated method stub
			ListView lView=(ListView)arg0;
			Cursor cursor=(Cursor) lView.getItemAtPosition(arg2);
			int StrId=cursor.getInt(cursor.getColumnIndex("_id"));
			Toast.makeText(getApplicationContext(), "序号为"+StrId,Toast.LENGTH_SHORT).show();
		}
	}

方法三、自定义方式绑定数据：定义PersonAdapter 类继承与 BaseAdapter

1）类实现：

public class PersonAdapter extends BaseAdapter {
	private List<person> persons;//在绑定的数据
	private int resouce;//绑定的条目界面
	private LayoutInflater inflater; //系统服务，布局填充服务
	public PersonAdapter(Context context, List<person> persons,int resouce) {
		this.persons = persons;
		this.resouce=resouce;
		inflater =(LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
	}

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

	@Override
	public Object getItem(int position) {
		// TODO Auto-generated method stub
		return persons.get(position);
	}

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

	@Override
	public View getView(int position, View convertView, ViewGroup parent) {
		// TODO Auto-generated method stub
		if(convertView==null)
		{
			convertView=inflater.inflate(resouce, null);
		}
		
		TextView idView=(TextView)convertView.findViewById(R.id.textId);
		TextView nameView=(TextView)convertView.findViewById(R.id.textName);
		TextView phoneView=(TextView)convertView.findViewById(R.id.textPhone);
		person p=persons.get(position);
		
		idView.setText("【"+p.getId()+"】");
		nameView.setText(p.getName());
		phoneView.setText(p.getPhone());
		
		return convertView;
	}

}

2）调用

	private void show3() {
		// TODO Auto-generated method stub
		List<person> lp=ps.getPage(0, 100);
		PersonAdapter adapter=new PersonAdapter(this,lp,R.layout.item);
		listView.setAdapter(adapter);
		listView.setOnItemClickListener(new ItemClickListener3());
	}
	private final class ItemClickListener3 implements OnItemClickListener{
		@Override
		public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,long arg3) {
			// TODO Auto-generated method stub
			ListView lV=(ListView)arg0;
			person p=(person)lV.getItemAtPosition(arg2);
			Toast.makeText(getApplicationContext(), p.getName(),Toast.LENGTH_SHORT).show();
		}
	}
