自己现实的仿微信通讯录列表

自己项目中需要做一个通讯录，单是和微信不一样，微信通讯录头部的几列好像是固定的，但是项目中的头部是群组管理，是动态的，对其联系人还需要做首字母排序，效果倒是很容易做出来，但是这里只能放一个listview，不然list就不能实现随侧边栏字母滑动查找，所以自己想了个办法

分享一下，同时也是复习，希望看到的童鞋有帮助

首先我重写了listview，在listview的头部添加了一个listview(注意：头部的list是添加到父list的第一行中，即position=0)

public class DrawListView extends ListView {

	private Context context;
	private LinearLayout llList;
	public LineListView topList;

	public DrawListView(Context context) {
		super(context);
		// TODO Auto-generated constructor stub
		this.context = context;
	}

	public DrawListView(Context context, AttributeSet attrs, int defStyle) {
		super(context, attrs, defStyle);
		// TODO Auto-generated constructor stub
		this.context = context;
		initUI();
	}

	public DrawListView(Context context, AttributeSet attrs) {
		super(context, attrs);
		// TODO Auto-generated constructor stub
		this.context = context;
		initUI();
	}

	private void initUI() {
		// TODO Auto-generated method stub
		llList = (LinearLayout) LayoutInflater.from(context).inflate(
				R.layout.top_layout, null);
		addHeaderView(llList);

		topList = (LineListView) llList.findViewById(R.id.top_list);
	}

}

其中头部是linelistview（简单是自适应高度listview）,这个就是父list头部的list用来做群组管理的

public class LineListView extends ListView {

	public LineListView(Context context) {
		super(context);
		// TODO Auto-generated constructor stub
	}

	public LineListView(Context context, AttributeSet attrs) {
		super(context, attrs);
		// TODO Auto-generated constructor stub
	}
	
	 public void onMeasure(int widthMeasureSpec, int heightMeasureSpec){  
         int mExpandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);  
         super.onMeasure(widthMeasureSpec, mExpandSpec);  
    }  

}

在activity中使用：

其实也很简单，分别给对应的listview都加上监听器，经过测试发现没有问题，只是操作父list的时候要注意，他的第一行被子list给占了，不能用来显示数据

所以父list在获取数据的时候，请记得position-1（自己调试一下就知道了）

public class MainActivity extends Activity {

	private DrawListView dlist;
	private ListAdapter lAdapter;
	private ListAdapter tAdapter;

	private String[] names = new String[] { "路飞", "乔巴", "索隆", "山治", "娜美", "罗宾",
			"乌索普", "布鲁克", "香克斯", "罗杰", "艾斯", "桑尼号", "梅丽号", "弗兰奇", "多福朗明哥" };

	private String[] lol = new String[] { "好运姐", "锤石", "金克斯", "阿狸", "猴子", "盖伦",
			"皇子", "盲僧", "日女", "豹女", "刀妹", "刀锋", "安妮", "男枪", "女警", "鳄鱼", "炮娘",
			"提莫", "慎", "赵信", "VN", "断头台", "风女", "莫甘娜", "妖姬", "&猪女", "%炸弹人",
			"*寒冰", "蛮子" };
	private List<String> l1 = new ArrayList<String>();
	private List<String> l2 = new ArrayList<String>();

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		dlist = (DrawListView) findViewById(R.id.list);
		dlist.setOnItemClickListener(new OnItemClickListener() {

			@Override
			public void onItemClick(AdapterView<?> parent, View view,
					int position, long id) {
				// TODO Auto-generated method stub
				Toast.makeText(MainActivity.this, l1.get(position-1), Toast.LENGTH_SHORT).show();
			}
		});
		getData();

		lAdapter = new ListAdapter(this, l1);
		dlist.setAdapter(lAdapter);
		
		tAdapter = new ListAdapter(this, l2);
		dlist.topList.setAdapter(tAdapter);
		dlist.topList.setOnItemClickListener(new OnItemClickListener() {

			@Override
			public void onItemClick(AdapterView<?> parent, View view,
					int position, long id) {
				// TODO Auto-generated method stub
				Toast.makeText(MainActivity.this, l2.get(position), Toast.LENGTH_SHORT).show();
				addData();
				tAdapter.notifyDataSetChanged();
			}
		});
	}

	private void getData() {
		for (int i = 0; i < names.length; i++) {
			l1.add(names[i]);
		}

		for (int i = 0; i < lol.length; i++) {
			l2.add(lol[i]);
		}
	}
	
	
	private void addData(){
		l1.add("我才是老大，懂？");
		l2.add("我才是老大，懂？");
	}
}

简单的实现了在listview的头部加了个listview，这样listview就可以适应通讯录的侧边栏滑动到具体的字母排序的地方
