联系人案例

项目中有用到联系人,就研究了下,参考了别人的demo,并且加上了自己的一些想法跟ui效果.有这方面需求的朋友可以拿去参考一下.

联系人字母排序参考文章,我也是参考他的:http://blog.csdn.net/xiaanming/article/details/12684155

我的项目实现了联系人排序,侧滑可以弹出联系人分组,以及添加联系人,删掉了搜索功能.增加了头像跟电话号码展示.

首先看下效果图片:

1.主MainActivity用来展示SlidingMenu    SlidingMenu加载左侧fragment(GroupFragment)    跟    中间的fragment (ContactFragment)

 注意: 把ContactFragment对象注入到GroupFragment中,因为点击群组的时候要更新ContactFragment界面.

1. public class MainActivity extends FragmentActivity {  
2.     private SlidingMenu mSlidingMenu;  
3.       
4.     @Override  
5.     protected void onCreate(Bundle savedInstanceState) {  
6.         super.onCreate(savedInstanceState);  
7.         setContentView(R.layout.contact_main);  
8.           
9.         initViews();  
10.           
11.         ImageView showGroup=(ImageView) findViewById(R.id.show_group);  
12.         showGroup.setOnClickListener(listener);  
13.           
14.         ImageView addContact=(ImageView) findViewById(R.id.add_contact);  
15.         addContact.setOnClickListener(listener);  
16.     }  
17.       
18.     private void initViews() {  
19.         mSlidingMenu = (SlidingMenu) findViewById(R.id.slidingmenu);  
20.           
21.         mSlidingMenu.setContent(R.layout.contact_fragment);//中间布局  
22.         mSlidingMenu.setMenu(R.layout.group_fragment);//左边布局  
23.           
24.         ContactFragment contactFragment=new ContactFragment();  
25.           
26.         FragmentTransaction ft=getSupportFragmentManager().beginTransaction();  
27.         ft.replace(R.id.contacts_fragment,contactFragment);  
28.         ft.replace(R.id.group_fragment,new GroupFragment(contactFragment));  
29.         ft.commit();  
30.     }  
31.       
32.     private OnClickListener listener=new OnClickListener() {  
33.         @Override  
34.         public void onClick(View v){  
35.             switch (v.getId()) {  
36.             case R.id.show_group:  
37.                 mSlidingMenu.toggle();//动态判断自动关闭或开启SlidingMenu  
38.                 break;  
39.             case R.id.add_contact:  
40.                 Intent intent = new Intent(Intent.ACTION_INSERT,Contacts.CONTENT_URI);  
41.                 startActivityForResult(intent,108);  
42.                 break;  
43.             }  
44.         }  
45.     };  
46.       
47.     protected void onActivityResult(int requestCode, int resultCode, Intent data) {  
48.         if (108 == requestCode){  
49.             Toast.makeText(MainActivity.this, "如果操作数据,请重新打开联系人...",Toast.LENGTH_LONG).show();  
50.         }  
51.         super.onActivityResult(requestCode, resultCode, data);  
52.     }  
53.   
54.     @Override  
55.     public boolean onKeyUp(int keyCode, KeyEvent event) {  
56.         if (keyCode == KeyEvent.KEYCODE_BACK && mSlidingMenu.isMenuShowing()) {  
57.             mSlidingMenu.showContent();  
58.             return true;  
59.         }  
60.         return super.onKeyUp(keyCode, event);  
61.     }  
62. }  

2.  ContactFragment  (中间内容显示的fragment)    初始化显示所有联系人.

     给SideBar添加监听事件,dialog的注入,ListView注入adapter,很简单的,相信大家都能看懂

1. public class ContactFragment extends Fragment implements GroupItemClick{  
2.     private List<SWWContact> contactList;  
3.     private Activity activity;  
4.     private ListView sortListView;  
5.     private ContactsAdapter adapter;  
6.       
7.     public View onCreateView(LayoutInflater inflater, ViewGroup container,  
8.             Bundle savedInstanceState) {  
9.         Log.i("fragment","onCreateView:"+getClass().getSimpleName());  
10.         activity=getActivity();  
11.         View mView = inflater.inflate(R.layout.contact_list, null);  
12.           
13.         SideBar sideBar = (SideBar) mView.findViewById(R.id.sidrbar);  
14.         TextView dialog = (TextView) mView.findViewById(R.id.dialog);  
15.         sideBar.setTextView(dialog);  
16.           
17.         //为ListView设置adapter  
18.         sortListView = (ListView) mView.findViewById(R.id.country_lvcountry);  
19.         contactList=SWWContactDB.findAllContacts(activity.getContentResolver());  
20.         adapter = new ContactsAdapter(activity,contactList);  
21.         sortListView.setAdapter(adapter);  
22.           
23.         //设置右侧触摸监听  
24.         sideBar.setOnTouchingLetterChangedListener(new OnTouchingLetterChangedListener() {  
25.             @Override  
26.             public void onTouchingLetterChanged(String s) {  
27.                 //该字母首次出现的位置  
28.                 int position = adapter.getPositionForSection(s.charAt(0));  
29.                 if(position != -1){  
30.                     sortListView.setSelection(position);  
31.                 }  
32.             }  
33.         });  
34.         return mView;  
35.     }  
36.       
37.     @Override  
38.     public void itemClick(List<SWWContact> contacts) {  
39.         adapter.updateListView(contacts);  
40.     }  
41. }  

3.GroupFragment  展示左侧群组数据,加载所有群组,以及群组点击事件,刷新右边联系人.

1. @SuppressLint("ValidFragment")  
2. public class GroupFragment extends Fragment {  
3.     private Activity activity;  
4.     private List<SWWContactsGroup> groupList=new ArrayList<SWWContactsGroup>();  
5.       
6.     private GroupItemClick groupClick;  
7.       
8.     public GroupFragment(){  
9.     }  
10.       
11.     public GroupFragment(GroupItemClick groupClick){  
12.         this.groupClick=groupClick;  
13.     }  
14.       
15.     public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {  
16.         Log.i("fragment", "onCreateView:"+getClass().getSimpleName());  
17.         activity=getActivity();  
18.         this.groupList = SWWContactDB.queryGroup(activity);//得到所有组数据  
19.           
20.         View view = inflater.inflate(R.layout.group_list, null);  
21.         ListView groupListView=(ListView)view.findViewById(R.id.group_list);  
22.         groupListView.setAdapter(new MyAdapter());  
23.         return view;  
24.     }  
25.       
26.     /** 
27.      * 左侧联系人分组  点击回调接口 
28.      */  
29.     public interface GroupItemClick{  
30.         public void itemClick(List<SWWContact> contacts);  
31.     }  
32.       
33.       
34.     private class MyAdapter extends BaseAdapter{  
35.         private boolean isPressed[];  
36.           
37.         public MyAdapter(){  
38.             if(groupList.size()>0){  
39.                 isPressed = new boolean[groupList.size()];  
40.                 isPressed[0]=true;  
41.             }  
42.         }  
43.           
44.         @Override  
45.         public int getCount() {  
46.             return groupList.size();  
47.         }  
48.   
49.         @Override  
50.         public Object getItem(int position) {  
51.             return groupList.get(position);  
52.         }  
53.   
54.         @Override  
55.         public long getItemId(int position) {  
56.             return groupList.get(position).getGroupId();  
57.         }  
58.   
59.         @Override  
60.         public View getView(final int position, View convertView, ViewGroup parent) {  
61.             ViewHolder holder;  
62.             if(null==convertView){  
63.                 holder=new ViewHolder();  
64.                 convertView=View.inflate(activity,R.layout.group_list_item, null);  
65.                 holder.groupName=(TextView) convertView.findViewById(R.id.group_name);  
66.                 convertView.setTag(holder);  
67.             }else{  
68.                 holder=(ViewHolder) convertView.getTag();  
69.             }  
70.             holder.groupName.setText(groupList.get(position).getGroupName());  
71.               
72.             holder.groupName.setBackgroundResource(isPressed[position]==true?R.color.light_blue:R.color.group_list);  
73.             holder.groupName.setOnClickListener(new OnClickListener() {  
74.                 @Override  
75.                 public void onClick(View v) {  
76.                     changeState(position);  
77.                     notifyDataSetChanged();  
78.                     if(position==0){//点击全部按钮  
79.                         groupClick.itemClick(SWWContactDB.findAllContacts(activity.getContentResolver()));  
80.                     }else{  
81.                         int groupId=groupList.get(position).getGroupId();  
82.                         groupClick.itemClick(SWWContactDB.queryGroupMember(groupId,activity));  
83.                     }  
84.                 }  
85.             });  
86.             return convertView;  
87.         }  
88.           
89.         private void changeState(int position){  
90.             isPressed=new boolean[isPressed.length];  
91.             isPressed[position] = true;  
92.         }  
93.           
94.         private  class ViewHolder{  
95.             private TextView groupName;  
96.         }  
97.     }  
98. }  

还有一些访问数据库, 以及一些工具类,我就不一一贴出来了,需要的要自己去下载源码......如果大家有什么疑问,请在下面留言.
