界面及初始化
我們先來一個直觀的界面感受。
首先是干嘛，是填充了該ListView的頭部。
@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);
}
接著我們來看其他方法。
刷新聯系人
刷新聯系人及邀請信息。
@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());
}
});
//設置聯系人數據
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中直接進入聊天頁面，實際一般是進入用戶詳情頁
startActivity(new Intent(getActivity(), ChatActivity.class).putExtra("userId", username));
}
}
});
?
// 進入添加好友頁
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);
}
}
常規的一些界面操作。
注冊同步監聽
比較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);
}
添加了三個同步監聽。
addSyncContactListener 同步聯系人監聽
addSyncBlackListListener 同步黑名單監聽
addSyncContactInfoListener 同步聯系人信息監聽
以及判斷是否需要同步的
isContactsSyncedWithServer
isSyncingContactsWithServer
兩個方法。
我們再來看其他的方法。
注冊同步監聽
@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);
}
注銷四個監聽。
protected class HeaderItemClickListener implements OnClickListener{
?
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.application_item:
// 進入申請與通知頁面
startActivity(new Intent(getActivity(), NewFriendsMsgActivity.class));
break;
case R.id.group_item:
// 進入群聊列表頁面
startActivity(new Intent(getActivity(), GroupsActivity.class));
break;
case R.id.chat_room_item:
//進入聊天室列表頁面
startActivity(new Intent(getActivity(), PublicChatRoomsActivity.class));
break;
case R.id.robot_item:
//進入Robot列表頁面
startActivity(new Intent(getActivity(), RobotsActivity.class));
break;
?
default:
break;
}
}
headview四條目監聽。
刪除聯系人及其他監聽實現?
/**
* 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();
}
}
});
}
}
刪除聯系人，主要兩句話。
EMClient.getInstance().contactManager().deleteContact
以及
DemoHelper.getInstance().getContactList().remove(tobeDeleteUser.getUsername());
其他監聽均實現了DataSyncListener接口。
下面，我們來看他爹。

填充布局
照例的填充布局
我們看到就一個search。
繼續看其他的方法
@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，沖突標志位，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;
}
});
}
尋常的初始化。
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();
}
}
?
?
/**
* move user to blacklist
*/
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。
聯系人排序?
/**
* 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());
}
?
}
});
?
}
聯系人的排序，將會過濾掉黑名單人員。
各種點擊監聽?
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 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;
}
正常的點擊事件。
他爺爺是EaseBaseFragment之前分析過就不分析了。
