简介：

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.

 
 public class MainActivity extends FragmentActivity {  
    private SlidingMenu mSlidingMenu;  
      
    @Override  
    protected void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);  
        setContentView(R.layout.contact_main);  
          
        initViews();  
          
        ImageView showGroup=(ImageView) findViewById(R.id.show_group);  
        showGroup.setOnClickListener(listener);  
          
        ImageView addContact=(ImageView) findViewById(R.id.add_contact);  
        addContact.setOnClickListener(listener);  
    }  
      
    private void initViews() {  
        mSlidingMenu = (SlidingMenu) findViewById(R.id.slidingmenu);  
          
        mSlidingMenu.setContent(R.layout.contact_fragment);//中间布局  
        mSlidingMenu.setMenu(R.layout.group_fragment);//左边布局  
          
        ContactFragment contactFragment=new ContactFragment();  
          
        FragmentTransaction ft=getSupportFragmentManager().beginTransaction();  
        ft.replace(R.id.contacts_fragment,contactFragment);  
        ft.replace(R.id.group_fragment,new GroupFragment(contactFragment));  
        ft.commit();  
    }  
      
    private OnClickListener listener=new OnClickListener() {  
        @Override  
        public void onClick(View v){  
            switch (v.getId()) {  
            case R.id.show_group:  
                mSlidingMenu.toggle();//动态判断自动关闭或开启SlidingMenu  
                break;  
            case R.id.add_contact:  
                Intent intent = new Intent(Intent.ACTION_INSERT,Contacts.CONTENT_URI);  
                startActivityForResult(intent,108);  
                break;  
            }  
        }  
    };  
      
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {  
        if (108 == requestCode){  
            Toast.makeText(MainActivity.this, "如果操作数据,请重新打开联系人...",Toast.LENGTH_LONG).show();  
        }  
        super.onActivityResult(requestCode, resultCode, data);  
    }  
  
    @Override  
    public boolean onKeyUp(int keyCode, KeyEvent event) {  
        if (keyCode == KeyEvent.KEYCODE_BACK && mSlidingMenu.isMenuShowing()) {  
            mSlidingMenu.showContent();  
            return true;  
        }  
        return super.onKeyUp(keyCode, event);  
    }  
}  
 

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

 
 public class ContactFragment extends Fragment implements GroupItemClick{  
    private List<SWWContact> contactList;  
    private Activity activity;  
    private ListView sortListView;  
    private ContactsAdapter adapter;  
      
    public View onCreateView(LayoutInflater inflater, ViewGroup container,  
            Bundle savedInstanceState) {  
        Log.i("fragment","onCreateView:"+getClass().getSimpleName());  
        activity=getActivity();  
        View mView = inflater.inflate(R.layout.contact_list, null);  
          
        SideBar sideBar = (SideBar) mView.findViewById(R.id.sidrbar);  
        TextView dialog = (TextView) mView.findViewById(R.id.dialog);  
        sideBar.setTextView(dialog);  
          
        //为ListView设置adapter  
        sortListView = (ListView) mView.findViewById(R.id.country_lvcountry);  
        contactList=SWWContactDB.findAllContacts(activity.getContentResolver());  
        adapter = new ContactsAdapter(activity,contactList);  
        sortListView.setAdapter(adapter);  
          
        //设置右侧触摸监听  
        sideBar.setOnTouchingLetterChangedListener(new OnTouchingLetterChangedListener() {  
            @Override  
            public void onTouchingLetterChanged(String s) {  
                //该字母首次出现的位置  
                int position = adapter.getPositionForSection(s.charAt(0));  
                if(position != -1){  
                    sortListView.setSelection(position);  
                }  
            }  
        });  
        return mView;  
    }  
      
    @Override  
    public void itemClick(List<SWWContact> contacts) {  
        adapter.updateListView(contacts);  
    }  
}  
 

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.

 
 @SuppressLint("ValidFragment")  
public class GroupFragment extends Fragment {  
    private Activity activity;  
    private List<SWWContactsGroup> groupList=new ArrayList<SWWContactsGroup>();  
      
    private GroupItemClick groupClick;  
      
    public GroupFragment(){  
    }  
      
    public GroupFragment(GroupItemClick groupClick){  
        this.groupClick=groupClick;  
    }  
      
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {  
        Log.i("fragment", "onCreateView:"+getClass().getSimpleName());  
        activity=getActivity();  
        this.groupList = SWWContactDB.queryGroup(activity);//得到所有组数据  
          
        View view = inflater.inflate(R.layout.group_list, null);  
        ListView groupListView=(ListView)view.findViewById(R.id.group_list);  
        groupListView.setAdapter(new MyAdapter());  
        return view;  
    }  
      
    /** 
     * 左侧联系人分组  点击回调接口 
     */  
    public interface GroupItemClick{  
        public void itemClick(List<SWWContact> contacts);  
    }  
      
      
    private class MyAdapter extends BaseAdapter{  
        private boolean isPressed[];  
          
        public MyAdapter(){  
            if(groupList.size()>0){  
                isPressed = new boolean[groupList.size()];  
                isPressed[0]=true;  
            }  
        }  
          
        @Override  
        public int getCount() {  
            return groupList.size();  
        }  
  
        @Override  
        public Object getItem(int position) {  
            return groupList.get(position);  
        }  
  
        @Override  
        public long getItemId(int position) {  
            return groupList.get(position).getGroupId();  
        }  
  
        @Override  
        public View getView(final int position, View convertView, ViewGroup parent) {  
            ViewHolder holder;  
            if(null==convertView){  
                holder=new ViewHolder();  
                convertView=View.inflate(activity,R.layout.group_list_item, null);  
                holder.groupName=(TextView) convertView.findViewById(R.id.group_name);  
                convertView.setTag(holder);  
            }else{  
                holder=(ViewHolder) convertView.getTag();  
            }  
            holder.groupName.setText(groupList.get(position).getGroupName());  
              
            holder.groupName.setBackgroundResource(isPressed[position]==true?R.color.light_blue:R.color.group_list);  
            holder.groupName.setOnClickListener(new OnClickListener() {  
                @Override  
                public void onClick(View v) {  
                    changeState(position);  
                    notifyDataSetChanged();  
                    if(position==0){//点击全部按钮  
                        groupClick.itemClick(SWWContactDB.findAllContacts(activity.getContentResolver()));  
                    }else{  
                        int groupId=groupList.get(position).getGroupId();  
                        groupClick.itemClick(SWWContactDB.queryGroupMember(groupId,activity));  
                    }  
                }  
            });  
            return convertView;  
        }  
          
        private void changeState(int position){  
            isPressed=new boolean[isPressed.length];  
            isPressed[position] = true;  
        }  
          
        private  class ViewHolder{  
            private TextView groupName;  
        }  
    }  
}
