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(lèi)繼承下來(lái)的了，我們看具體的代碼
EaseBaseFragment

import android.support.v4.app.Fragment;
import android.view.View;
import android.view.WindowManager;

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(){

}
}
public void hideTitleBar(){

}
}
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。
@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);
initView();
setUpView();
}
隱藏輸入法
看到inputmethdManager要干嘛啊，隱藏鍵盤(pán)。果不其然。
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？
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，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(){
if(titleBar != null){

}
}

填充布局

覆寫(xiě)爺爺?shù)募乙?guī)，初始化View輸入法管理器
會(huì)話(huà)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

}
});
我們一句句的看
conversationList.addAll(loadConversationList());
conversationListView.init(conversationList);
會(huì)話(huà)列表添加全部以及數(shù)據(jù)填充初始化。
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。
// 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(huà)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，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，大致是這么個(gè)意思。
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(huà)時(shí)間戳來(lái)排序。
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。
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)。
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(hù)是否移除，是否在其他設(shè)備登陸，或者服務(wù)端的服務(wù)受到限制，是的話(huà)則標(biāo)記沖突。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;
}
}
};
干嘛啊？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;
}
});
干了些什么啊？查詢(xún)、清除搜索、會(huì)話(huà)列表點(diǎn)擊監(jiān)聽(tīng)。
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，然后去服務(wù)器拿并排序，然后刷新listview。其中該listview為自定義的EaseConversationList。
那么兒子齊活了，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。
registerForContextMenu(conversationListView);
注冊(cè)上下文菜單

條目的點(diǎn)擊監(jiān)聽(tīng)
其中做了這么些事情：
判斷用戶(hù)名是否等于當(dāng)前登陸用戶(hù)，是則提示不能跟自己聊天
如果是群聊的話(huà)，則繼續(xù)判斷是聊天室還是群組，并帶值給ChatActivity即聊天界面
最后將用戶(hù)名帶上，跳轉(zhuǎn)ChatActivity。
//red packet code : 紅包回執(zhí)消息在會(huì)話(huà)列表最后一條消息的展示
conversationListView.setConversationListHelper(new EaseConversationListHelper() {
@Override

最后是紅包回執(zhí)信息。
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。
@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

((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，第一個(gè)界面，會(huì)話(huà)界面到此結(jié)束。
我們?cè)賮?lái)看通訊錄界面。
