}
界面及初始化

我们先来一个直观的界面感受。
首先是干嘛，是填充了该ListView的头部。

001.jpg

 

@SuppressLint("InflateParams")

@Override

protected void initView() {

    super.initView();

    @SuppressLint("InflateParams") View headerView = LayoutInflater.from(getActivity()).inflate(R.layout.em_contacts_header, null);

    HeaderItemClickListener clickListener = new HeaderItemClickListener();

    applicationItem = (ContactItemView) headerView.findViewById(R.id.application_item);

    applicationItem.setOnClickListener(clickListener);

    headerView.findViewById(R.id.group_item).setOnClickListener(clickListener);

    headerView.findViewById(R.id.chat_room_item).setOnClickListener(clickListener);

    headerView.findViewById(R.id.robot_item).setOnClickListener(clickListener);

    listView.addHeaderView(headerView);

    //add loading view

    loadingView = LayoutInflater.from(getActivity()).inflate(R.layout.em_layout_loading_data, null);

    contentContainer.addView(loadingView);

​

    registerForContextMenu(listView);

}
接着我们来看其他方法。

刷新联系人

刷新联系人及邀请信息。
 @SuppressWarnings("unchecked")

    @Override

    protected void setUpView() {

        titleBar.setRightImageResource(R.drawable.em_add);

        titleBar.setRightLayoutClickListener(new OnClickListener() {


            @Override

            public void onClick(View v) {

//                startActivity(new Intent(getActivity(), AddContactActivity.class));

                NetUtils.hasDataConnection(getActivity());

            }

        });

        //设置联系人数据

        Map<String, EaseUser> m = DemoHelper.getInstance().getContactList();

        if (m instanceof Hashtable<?, ?>) {

            m = (Map<String, EaseUser>) ((Hashtable<String, EaseUser>)m).clone();

        }

        setContactsMap(m);

        super.setUpView();

        listView.setOnItemClickListener(new OnItemClickListener() {

​

            @Override

            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

                EaseUser user = (EaseUser)listView.getItemAtPosition(position);

                if (user != null) {

                    String username = user.getUsername();

                    // demo中直接进入聊天页面，实际一般是进入用户详情页

                    startActivity(new Intent(getActivity(), ChatActivity.class).putExtra("userId", username));

                }

            }

        });

​


        // 进入添加好友页

        titleBar.getRightLayout().setOnClickListener(new OnClickListener() {

​

            @Override

            public void onClick(View v) {

                startActivity(new Intent(getActivity(), AddContactActivity.class));

            }

        });



        contactSyncListener = new ContactSyncListener();

        DemoHelper.getInstance().addSyncContactListener(contactSyncListener);


        blackListSyncListener = new BlackListSyncListener();

        DemoHelper.getInstance().addSyncBlackListListener(blackListSyncListener);


        contactInfoSyncListener = new ContactInfoSyncListener();

        DemoHelper.getInstance().getUserProfileManager().addSyncContactInfoListener(contactInfoSyncListener);


        if (DemoHelper.getInstance().isContactsSyncedWithServer()) {

            loadingView.setVisibility(View.GONE);

        } else if (DemoHelper.getInstance().isSyncingContactsWithServer()) {

            loadingView.setVisibility(View.VISIBLE);

        }

    }
常规的一些界面操作。

注册同步监听

比较有趣的是如下的操作。
contactSyncListener = new ContactSyncListener();

DemoHelper.getInstance().addSyncContactListener(contactSyncListener);

​

blackListSyncListener = new BlackListSyncListener();

DemoHelper.getInstance().addSyncBlackListListener(blackListSyncListener);

​

contactInfoSyncListener = new ContactInfoSyncListener();

DemoHelper.getInstance().getUserProfileManager().addSyncContactInfoListener(contactInfoSyncListener);

​

if (DemoHelper.getInstance().isContactsSyncedWithServer()) {

    loadingView.setVisibility(View.GONE);

} else if (DemoHelper.getInstance().isSyncingContactsWithServer()) {

    loadingView.setVisibility(View.VISIBLE);

}
添加了三个同步监听。
  • addSyncContactListener 同步联系人监听
  • addSyncBlackListListener 同步黑名单监听
  • addSyncContactInfoListener 同步联系人信息监听
以及判断是否需要同步的
  • isContactsSyncedWithServer
  • isSyncingContactsWithServer


两个方法。

我们再来看其他的方法。

注册同步监听
 

@Override

public void onDestroy() {

    super.onDestroy();

    if (contactSyncListener != null) {

        DemoHelper.getInstance().removeSyncContactListener(contactSyncListener);

        contactSyncListener = null;

    }


    if(blackListSyncListener != null){

        DemoHelper.getInstance().removeSyncBlackListListener(blackListSyncListener);

    }


    if(contactInfoSyncListener != null){

        DemoHelper.getInstance().getUserProfileManager().removeSyncContactInfoListener(contactInfoSyncListener);

    }
注销四个监听。
 

protected class HeaderItemClickListener implements OnClickListener{

​

       @Override

       public void onClick(View v) {

           switch (v.getId()) {

           case R.id.application_item:

               // 进入申请与通知页面

               startActivity(new Intent(getActivity(), NewFriendsMsgActivity.class));

               break;

           case R.id.group_item:

               // 进入群聊列表页面

               startActivity(new Intent(getActivity(), GroupsActivity.class));

               break;

           case R.id.chat_room_item:

               //进入聊天室列表页面

               startActivity(new Intent(getActivity(), PublicChatRoomsActivity.class));

               break;

           case R.id.robot_item:

               //进入Robot列表页面

               startActivity(new Intent(getActivity(), RobotsActivity.class));

               break;

​

           default:

               break;

           }

       }
headview四条目监听。

删除联系人，主要两句话。
 EMClient.getInstance().contactManager().deleteContact

DemoHelper.getInstance().getContactList().remove(tobeDeleteUser.getUsername());
其他监听均实现了DataSyncListener接口。

拉黑，以及刷新。

联系人排序​
/**

 * get contact list and sort, will filter out users in blacklist

 */

protected void getContactList() {

    contactList.clear();

    if(contactsMap == null){

        return;

    }

            // to make it compatible with data in previous version, you can remove this check if this is new app

            if (!entry.getKey().equals("item_new_friends")

                    && !entry.getKey().equals("item_groups")

                    && !entry.getKey().equals("item_chatroom")

                    //filter out users in blacklist

                    EaseUser user = entry.getValue();

                    EaseCommonUtils.setUserInitialLetter(user);

                    contactList.add(user);

                }

            }

        }

    }

​

    // sorting

    Collections.sort(contactList, new Comparator<EaseUser>() {

​

        @Override

        public int compare(EaseUser lhs, EaseUser rhs) {

            if(lhs.getInitialLetter().equals(rhs.getInitialLetter())){

                return lhs.getNick().compareTo(rhs.getNick());

            }else{

                if("#".equals(lhs.getInitialLetter())){

                    return 1;

                }else if("#".equals(rhs.getInitialLetter())){

                    return -1;

                }

                return lhs.getInitialLetter().compareTo(rhs.getInitialLetter());

            }

​

        }

    });

​

}
联系人的排序，将会过滤掉黑名单人员。

各种点击监听​
protected EMConnectionListener connectionListener = new EMConnectionListener() {


    @Override

    public void onDisconnected(int error) {

        if (error == EMError.USER_REMOVED || error == EMError.USER_LOGIN_ANOTHER_DEVICE || error == EMError.SERVER_SERVICE_RESTRICTED) {

            isConflict = true;

        } else {

            getActivity().runOnUiThread(new Runnable() {

                public void run() {

                    onConnectionDisconnected();

                }

​

            });

        }

    }


    @Override

    public void onConnected() {

        getActivity().runOnUiThread(new Runnable() {

            public void run() {

                onConnectionConnected();

            }

​

        });

    }

};

private EaseContactListItemClickListener listItemClickListener;

​

​

protected void onConnectionDisconnected() {


}

​

protected void onConnectionConnected() {


}

​

/**

 * set contacts map, key is the hyphenate id

 * @param contactsMap

 */

public void setContactsMap(Map<String, EaseUser> contactsMap){

    this.contactsMap = contactsMap;

}

​

public interface EaseContactListItemClickListener {

    /**

     * on click event for item in contact list 

     * @param user --the user of item

     */

    void onListItemClicked(EaseUser user);

}

​

/**

 * set contact list item click listener

 * @param listItemClickListener

 */

public void setContactListItemClickListener(EaseContactListItemClickListener listItemClickListener){

    this.listItemClickListener = listItemClickListener;

}
正常的点击事件。

他爷爷是EaseBaseFragment之前分析过就不分析了。
