我們還是挨個(gè)來(lái)讀代碼

public abstract class EaseBaseFragment extends Fragment

爺爺終于正常點(diǎn)是從Android系統(tǒng)類繼承下來(lái)的了爪喘，我們看具體的代碼

import android.view.View;

@Override

public void onActivityCreated(Bundle savedInstanceState) {

super.onActivityCreated(savedInstanceState);

inputMethodManager = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);

//noinspection ConstantConditions

titleBar = (EaseTitleBar) getView().findViewById(R.id.title_bar);

setUpView();

}

public void showTitleBar(){

if(titleBar != null){

}

public void hideTitleBar(){

titleBar.setVisibility(View.GONE);

}

protected void hideSoftKeyboard() {

if (getActivity().getWindow().getAttributes().softInputMode != WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN) {

if (getActivity().getCurrentFocus() != null)

inputMethodManager.hideSoftInputFromWindow(getActivity().getCurrentFocus().getWindowToken(),

InputMethodManager.HIDE_NOT_ALWAYS);

}

protected abstract void initView();

protected abstract void setUpView();

}

我們還是挨個(gè)來(lái)看代碼，研究他的功能浮庐。

@Override

public void onActivityCreated(Bundle savedInstanceState) {

super.onActivityCreated(savedInstanceState);

inputMethodManager = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);

//noinspection ConstantConditions

titleBar = (EaseTitleBar) getView().findViewById(R.id.title_bar);

setUpView();

}

隱藏輸入法

看到inputmethdManager要干嘛啊，隱藏鍵盤。果不其然夷陋。

protected void hideSoftKeyboard() {

if (getActivity().getWindow().getAttributes().softInputMode != WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN) {

if (getActivity().getCurrentFocus() != null)

inputMethodManager.hideSoftInputFromWindow(getActivity().getCurrentFocus().getWindowToken(),

}

然后呢磅废？

初始化標(biāo)題頭?

//noinspection ConstantConditions

titleBar = (EaseTitleBar) getView().findViewById(R.id.title_bar);

最后初始化標(biāo)題頭母廷，并且讓子孫們?nèi)?shí)現(xiàn)抽象方法initView和setUpView().

隱藏和顯示標(biāo)題頭

其中還提供了兩個(gè)方法，隱藏和顯示標(biāo)題頭

public void showTitleBar(){

if(titleBar != null){

titleBar.setVisibility(View.VISIBLE);

}

public void hideTitleBar(){

覆寫爺爺?shù)募乙?guī)，初始化View輸入法管理器

會(huì)話列表List

查找聯(lián)系人的輸入框

清除搜索的按鈕

errorItemContainer 錯(cuò)誤標(biāo)簽容器

繼續(xù)看代碼setUpView()方法

setUpView()

conversationList.addAll(loadConversationList());

conversationListView.init(conversationList);

if(listItemClickListener != null){

conversationListView.setOnItemClickListener(new OnItemClickListener() {

@Override

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

EMConversation conversation = conversationListView.getItem(position);

listItemClickListener.onListItemClicked(conversation);

}

});

query.addTextChangedListener(new TextWatcher() {

public void onTextChanged(CharSequence s, int start, int before, int count) {

if (s.length() > 0) {

clearSearch.setVisibility(View.INVISIBLE);

clearSearch.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

query.getText().clear();

hideSoftKeyboard();

}

});

conversationListView.setOnTouchListener(new OnTouchListener() {

@Override

public boolean onTouch(View v, MotionEvent event) {

hideSoftKeyboard();

return false;

}

});

我們一句句的看

conversationList.addAll(loadConversationList());

conversationListView.init(conversationList);

會(huì)話列表添加全部以及數(shù)據(jù)填充初始化格带。

我們來(lái)看具體的方法

/**

* load conversation list

* @return

protected List loadConversationList(){

// get all conversations

Map conversations = EMClient.getInstance().chatManager().getAllConversations();

List> sortList = new ArrayList>();

/**

* lastMsgTime will change if there is new message during sorting

* so use synchronized to make sure timestamp of last message won't change.

synchronized (conversations) {

for (EMConversation conversation : conversations.values()) {

if (conversation.getAllMessages().size() != 0) {

sortList.add(new Pair(conversation.getLastMessage().getMsgTime(), conversation));

}

try {

// Internal is TimSort algorithm, has bug

sortConversationByLastChatTime(sortList);

} catch (Exception e) {

e.printStackTrace();

}

List list = new ArrayList();

for (Pair sortItem : sortList) {

list.add(sortItem.second);

}

return list;

}

loadConversationList()返回一個(gè)EMConversation對(duì)象List撤缴。

// get all conversations

Map conversations = EMClient.getInstance().chatManager().getAllConversations();

List> sortList = new ArrayList>();

通過(guò)封裝的chatManager拿到所有的會(huì)話列表

/**

* lastMsgTime will change if there is new message during sorting

* so use synchronized to make sure timestamp of last message won't change.

synchronized (conversations) {

for (EMConversation conversation : conversations.values()) {

if (conversation.getAllMessages().size() != 0) {

sortList.add(new Pair(conversation.getLastMessage().getMsgTime(), conversation));

}

lastMsgTime會(huì)隨著新消息的到來(lái)排序發(fā)生改變刹枉，所以我們用同步方法確保最新消息的時(shí)間戳不發(fā)生改變。

英文不好屈呕，大致是這么個(gè)意思微宝。

try {

// Internal is TimSort algorithm, has bug

sortConversationByLastChatTime(sortList);

} catch (Exception e) {

e.printStackTrace();

}

List list = new ArrayList();

for (Pair sortItem : sortList) {

list.add(sortItem.second);

}

return list;

其中還特地注釋了一把,算法有點(diǎn)bug。

/**

* sort conversations according time stamp of last message

* @param conversationList

private void sortConversationByLastChatTime(List> conversationList) {

Collections.sort(conversationList, new Comparator>() {

@Override

public int compare(final Pair con1, final Pair con2) {

if (con1.first.equals(con2.first)) {

return 0;

} else if (con2.first.longValue() > con1.first.longValue()) {

return 1;

} else {

return -1;

}

});

根據(jù)最新的會(huì)話時(shí)間戳來(lái)排序虎眨。

我們接著看

List list = new ArrayList();

for (Pair sortItem : sortList) {

list.add(sortItem.second);

}

return list;

添加完了返回list蟋软。

conversationListView.init(conversationList);

接著就初始化了。

if(listItemClickListener != null){

conversationListView.setOnItemClickListener(new OnItemClickListener() {

@Override

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

EMConversation conversation = conversationListView.getItem(position);

listItemClickListener.onListItemClicked(conversation);

}

});

}

然后便是連接接聽(tīng)

EMClient.getInstance().addConnectionListener(connectionListener);

添加了一個(gè)連接的監(jiān)聽(tīng)嗽桩。

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 {

handler.sendEmptyMessage(0);

}

@Override

public void onConnected() {

handler.sendEmptyMessage(1);

}

};

在斷開(kāi)連接時(shí)判斷用戶是否移除岳守，是否在其他設(shè)備登陸，或者服務(wù)端的服務(wù)受到限制碌冶，是的話則標(biāo)記沖突湿痢。不是則發(fā)送handler空消息。

protected Handler handler = new Handler(){

public void handleMessage(android.os.Message msg) {

switch (msg.what) {

case 0:

onConnectionDisconnected();

break;

case 1:

onConnectionConnected();

break;

case MSG_REFRESH:

{

conversationList.clear();

conversationList.addAll(loadConversationList());

conversationListView.refresh();

break;

}

default:

break;

}

};

干嘛捌伺印蒙袍？調(diào)用 onConnectionDisconnected 即連接斷開(kāi)的處理方法

/**

* disconnected with server

protected void onConnectionDisconnected(){

errorItemContainer.setVisibility(View.VISIBLE);

}

即顯示錯(cuò)誤條。

我們?cè)俳又创a

query.addTextChangedListener(new TextWatcher() {

public void onTextChanged(CharSequence s, int start, int before, int count) {

conversationListView.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();

}

});

conversationListView.setOnTouchListener(new OnTouchListener() {

@Override

public boolean onTouch(View v, MotionEvent event) {

hideSoftKeyboard();

return false;

}

});

干了些什么澳奂贰害幅？查詢、清除搜索岂昭、會(huì)話列表點(diǎn)擊監(jiān)聽(tīng)以现。

其他方法?

/**

* connected to server

protected void onConnectionConnected(){

errorItemContainer.setVisibility(View.GONE);

}

連接后將錯(cuò)誤條隱藏

case MSG_REFRESH:

{

conversationList.clear();

conversationList.addAll(loadConversationList());

conversationListView.refresh();

break;

}

服務(wù)器告訴要刷新了，那么我們就去清楚列表约啊，然后去服務(wù)器拿并排序邑遏，然后刷新listview。其中該listview為自定義的EaseConversationList恰矩。

那么兒子齊活了记盒，我們?cè)倏磳O子

添加了錯(cuò)誤的容器、初始化錯(cuò)誤消息控件外傅。

registerForContextMenu(conversationListView);

注冊(cè)上下文菜單

EMConversation conversation = conversationListView.getItem(position);

條目的點(diǎn)擊監(jiān)聽(tīng)

其中做了這么些事情：

判斷用戶名是否等于當(dāng)前登陸用戶纪吮，是則提示不能跟自己聊天

如果是群聊的話，則繼續(xù)判斷是聊天室還是群組萎胰，并帶值給ChatActivity即聊天界面

最后將用戶名帶上碾盟，跳轉(zhuǎn)ChatActivity。

//red packet code : 紅包回執(zhí)消息在會(huì)話列表最后一條消息的展示

conversationListView.setConversationListHelper(new EaseConversationListHelper() {

@Override

public String onSetItemSecondaryText(EMMessage lastMessage) {

return null;

}

});

super.setUpView();

最后是紅包回執(zhí)信息技竟。

我們接著看其他的方法

@Override

protected void onConnectionDisconnected() {

super.onConnectionDisconnected();

if (NetUtils.hasNetwork(getActivity())){

errorText.setText(R.string.can_not_connect_chat_server_connection);

} else {

errorText.setText(R.string.the_current_network);

}

端口網(wǎng)絡(luò)則提示沒(méi)網(wǎng)標(biāo)簽冰肴。

@Override

public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) {

getActivity().getMenuInflater().inflate(R.menu.em_delete_message, menu);

}

創(chuàng)建上下文菜單

@Overridepublic boolean onContextItemSelected(MenuItem item) {? ? boolean deleteMessage = false;? ? if (item.getItemId() == R.id.delete_message) {? ? ? ? deleteMessage = true;? ? } else if (item.getItemId() == R.id.delete_conversation) {? ? ? ? deleteMessage = false;? ? }? EMConversation tobeDeleteCons = conversationListView.getItem(((AdapterContextMenuInfo) item.getMenuInfo()).position);? if (tobeDeleteCons == null) {? ? ? return true;? }? ? if(tobeDeleteCons.getType() == EMConversationType.GroupChat){? ? ? ? EaseAtMessageHelper.get().removeAtMeGroup(tobeDeleteCons.conversationId());? ? }? ? try {? ? ? ? // delete conversation? ? ? ? EMClient.getInstance().chatManager().deleteConversation(tobeDeleteCons.conversationId(), deleteMessage);? ? ? ? InviteMessgeDao inviteMessgeDao = new InviteMessgeDao(getActivity());? ? ? ? inviteMessgeDao.deleteMessage(tobeDeleteCons.conversationId());? ? } catch (Exception e) {? ? ? ? e.printStackTrace();? ? }? ? refresh();?? ? // update unread count[url=http://www.imgeek.org/article/825308690]環(huán)信官方Demo源碼分析及SDK簡(jiǎn)單應(yīng)用-主界面的三個(gè)fragment-通訊錄界面[/url]? ? ((MainActivity) getActivity()).updateUnreadLabel();? ? return true;}

上下文菜單選擇的處理方法

刪除消息并更新未讀消息。

好，至此熙尉，第一個(gè)界面联逻，會(huì)話界面到此結(jié)束。

我們?cè)賮?lái)看通訊錄界面检痰。
