if(success){ refresh(); } } }); } } }
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。
@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 m = DemoHelper.getInstance().getContactList();
if (m instanceof Hashtable) {
m = (Map) ((Hashtable)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。
删除联系人及其他监听实现
/**
* delete contact
*
* @param toDeleteUser
*/
public void deleteContact(final EaseUser tobeDeleteUser) {
String st1 = getResources().getString(R.string.deleting);
final String st2 = getResources().getString(R.string.Delete_failed);
final ProgressDialog pd = new ProgressDialog(getActivity());
pd.setMessage(st1);
pd.setCanceledOnTouchOutside(false);
pd.show();
new Thread(new Runnable() {
public void run() {
try {
EMClient.getInstance().contactManager().deleteContact(tobeDeleteUser.getUsername());
// remove user from memory and database
UserDao dao = new UserDao(getActivity());
dao.deleteContact(tobeDeleteUser.getUsername());
DemoHelper.getInstance().getContactList().remove(tobeDeleteUser.getUsername());
getActivity().runOnUiThread(new Runnable() {
public void run() {
pd.dismiss();
contactList.remove(tobeDeleteUser);
contactListLayout.refresh();
}
});
} catch (final Exception e) {
getActivity().runOnUiThread(new Runnable() {
public void run() {
pd.dismiss();
Toast.makeText(getActivity(), st2 + e.getMessage(), Toast.LENGTH_LONG).show();
}
});
}
}
}).start();
}
class ContactSyncListener implements DataSyncListener{
@Override
public void onSyncComplete(final boolean success) {
EMLog.d(TAG, "on contact list sync success:" + success);
getActivity().runOnUiThread(new Runnable() {
public void run() {
getActivity().runOnUiThread(new Runnable(){
@Override
public void run() {
if(success){
loadingView.setVisibility(View.GONE);
refresh();
}else{
String s1 = getResources().getString(R.string.get_failed_please_check);
Toast.makeText(getActivity(), s1, Toast.LENGTH_LONG).show();
loadingView.setVisibility(View.GONE);
}
}
});
}
});
}
}
class BlackListSyncListener implements DataSyncListener{
@Override
public void onSyncComplete(boolean success) {
getActivity().runOnUiThread(new Runnable(){
@Override
public void run() {
refresh();
}
});
}
}
class ContactInfoSyncListener implements DataSyncListener{
@Override
public void onSyncComplete(final boolean success) {
EMLog.d(TAG, "on contactinfo list sync success:" + success);
getActivity().runOnUiThread(new Runnable() {
@Override
public void run() {
loadingView.setVisibility(View.GONE);
if(success){
refresh();
}
}
});
}
}
删除联系人，主要两句话。
EMClient.getInstance().contactManager().deleteContact
以及
DemoHelper.getInstance().getContactList().remove(tobeDeleteUser.getUsername());
其他监听均实现了DataSyncListener接口。
下面，我们来看他爹。

填充布局
照例的填充布局
我们看到就一个search。
继续看其他的方法
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.ease_fragment_contact_list, container, false);
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
//to avoid crash when open app after long time stay in background after user logged into another device
if(savedInstanceState != null && savedInstanceState.getBoolean("isConflict", false))
return;
super.onActivityCreated(savedInstanceState);
}
@Override
protected void initView() {
contentContainer = (FrameLayout) getView().findViewById(R.id.content_container);
contactListLayout = (EaseContactList) getView().findViewById(R.id.contact_list);
listView = contactListLayout.getListView();
//search
query = (EditText) getView().findViewById(R.id.query);
clearSearch = (ImageButton) getView().findViewById(R.id.search_clear);
}
照例的填充，冲突标志位，初始化view。
初始化view
@Override
protected void setUpView() {
EMClient.getInstance().addConnectionListener(connectionListener);
contactList = new ArrayList();
getContactList();
//init list
contactListLayout.init(contactList);
if(listItemClickListener != null){
listView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView parent, View view, int position, long id) {
EaseUser user = (EaseUser)listView.getItemAtPosition(position);
listItemClickListener.onListItemClicked(user);
}
});
}
query.addTextChangedListener(new TextWatcher() {
public void onTextChanged(CharSequence s, int start, int before, int count) {
contactListLayout.filter(s);
if (s.length() > 0) {
clearSearch.setVisibility(View.VISIBLE);
} else {
clearSearch.setVisibility(View.INVISIBLE);
}
}
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
public void afterTextChanged(Editable s) {
}
});
clearSearch.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
query.getText().clear();
hideSoftKeyboard();
}
});
listView.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
hideSoftKeyboard();
return false;
}
});
}
寻常的初始化。
拉黑及刷新
@Override
public void onHiddenChanged(boolean hidden) {
super.onHiddenChanged(hidden);
this.hidden = hidden;
if (!hidden) {
refresh();
}
}
@Override
public void onResume() {
super.onResume();
if (!hidden) {
refresh();
}
}
/**

*/
protected void moveToBlacklist(final String username){
final ProgressDialog pd = new ProgressDialog(getActivity());
String st1 = getResources().getString(R.string.Is_moved_into_blacklist);
final String st2 = getResources().getString(R.string.Move_into_blacklist_success);
final String st3 = getResources().getString(R.string.Move_into_blacklist_failure);
pd.setMessage(st1);
pd.setCanceledOnTouchOutside(false);
pd.show();
new Thread(new Runnable() {
public void run() {
try {
//move to blacklist
EMClient.getInstance().contactManager().addUserToBlackList(username,false);
getActivity().runOnUiThread(new Runnable() {
public void run() {
pd.dismiss();
Toast.makeText(getActivity(), st2, Toast.LENGTH_SHORT).show();
refresh();
}
});
} catch (HyphenateException e) {
e.printStackTrace();
getActivity().runOnUiThread(new Runnable() {
public void run() {
pd.dismiss();
Toast.makeText(getActivity(), st3, Toast.LENGTH_SHORT).show();
}
});
}
}
}).start();
}
// refresh ui
public void refresh() {
getContactList();
contactListLayout.refresh();
}
@Override
public void onDestroy() {
EMClient.getInstance().removeConnectionListener(connectionListener);
super.onDestroy();
}
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;
}
synchronized (this.contactsMap) {
Iterator> iterator = contactsMap.entrySet().iterator();
List blackList = EMClient.getInstance().contactManager().getBlackListUsernames();
while (iterator.hasNext()) {
Entry entry = iterator.next();
// 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")
&& !entry.getKey().equals("item_robots")){
if(!blackList.contains(entry.getKey())){
//filter out users in blacklist
EaseUser user = entry.getValue();
EaseCommonUtils.setUserInitialLetter(user);
contactList.add(user);
}
}
}
}
// sorting
Collections.sort(contactList, new Comparator() {
@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() {
