最近在项目中用到了即使用讯，客户要求用环信，我擦，第一次做，坑啊，网上对这个没有特别明确的使用教程，环信的官网也不像其他的第三方有明确的使用方法，只是说了一个简单的集成，看其他人的博客感觉都说的很麻烦，很含糊，所以现在项目完成了，做个简单的总结，希望能帮助到还不太会的童鞋~~

第一步，集成步骤

下载官方发demo，把easeui以Moudle的形式集成到自己的项目中

到这里就算集成完事了，接下来实现功能

1，首先实现基础的聊天功能

自己写一个Activity，比如我自己写了一个ChatRoomActivity，该activity的布局文件很简单

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:orientation="vertical"    android:fitsSystemWindows="true"    android:id="@+id/rl_beijing"    android:layout_width="match_parent"    android:layout_height="match_parent">    <com.smarttrust.hunlian.UI.TitlebarUI        android:id="@+id/titlebarUI"        android:layout_width="match_parent"        android:layout_height="wrap_content" />    <FrameLayout        android:background="@drawable/morenbeijing"        android:layout_below="@id/titlebarUI"        android:id="@+id/ec_layout_container"        android:layout_width="match_parent"        android:layout_height="match_parent">    </FrameLayout></RelativeLayout>

然后，自己写一个ChatFragment，继承EaseChatFragment，在ChatRoomActivity中

private FrameLayout ec_layout_container;private EaseChatFragment chatFragment;

    private void initChat(){         ///调用EaseUI封装好的聊天页面     chatFragment = new ChatFragment();        ///将参数传递给聊天页面     chatFragment.setArguments(getIntent().getExtras());        getSupportFragmentManager().beginTransaction().                add(R.id.ec_layout_container,chatFragment).commit();    }

到此就实现了简单的聊天功能，继续往下

聊天肯定要有头像，昵称，点击头像触发跳转（比如跳转到该人的主页），点击消息内容触发（删除该条消息，或者长按复制）

1，先说说怎么传头像，这里只要上传自己的头像然后对方接收即可，这里又回到上面的方法，在ChatRoomActivity中

    private void initChat(){        SharedPreferences preferences=getSharedPreferences("UserMessage", Context.MODE_PRIVATE);        String headurl=preferences.getString("headurl", "");//头像        String userNickname=preferences.getString("nickname", "");//昵称        ///调用EaseUI封装好的聊天页面     chatFragment = new ChatFragment();        chatFragment.setSetmobile(setmobile);        chatFragment.setUserNickname(userNickname);        chatFragment.setHearurl(headurl);//        chatFragment.setUrlBg(drawable);        ///将参数传递给聊天页面     chatFragment.setArguments(getIntent().getExtras());        getSupportFragmentManager().beginTransaction().                add(R.id.ec_layout_container,chatFragment).commit();    }

我这里在环信的EaseChatFragment中定义了昵称，头像的set，get方法，获取ChatRoomActivity中传过来的昵称和头像，扩展EMMessage，比如在发送文本，图片，位置，语音的地方扩展，找到如下方法进行拓展即可，代码如下

//send messageprotected void sendTextMessage(String content) {    if(EaseAtMessageHelper.get().containsAtUsername(content)){        sendAtMessage(content);    }else{        EMMessage message = EMMessage.createTxtSendMessage(content, toChatUsername);        message.setAttribute("headurl",getHearurl());        message.setAttribute("userNickname",getUserNickname());        sendMessage(message);        Log.e("sujd===========send",getHearurl());        Log.e("sujd===========send",getUserNickname());    }}

protected void sendBigExpressionMessage(String name, String identityCode){    EMMessage message = EaseCommonUtils.createExpressionMessage(toChatUsername, name, identityCode);    message.setAttribute("headurl",getHearurl());    message.setAttribute("userNickname",getUserNickname());    sendMessage(message);}protected void sendVoiceMessage(String filePath, int length) {    EMMessage message = EMMessage.createVoiceSendMessage(filePath, length, toChatUsername);    message.setAttribute("headurl",getHearurl());    message.setAttribute("userNickname",getUserNickname());    sendMessage(message);}protected void sendImageMessage(String imagePath) {    EMMessage message = EMMessage.createImageSendMessage(imagePath, false, toChatUsername);    message.setAttribute("headurl",getHearurl());    message.setAttribute("userNickname",getUserNickname());    sendMessage(message);}protected void sendLocationMessage(double latitude, double longitude, String locationAddress) {    EMMessage message = EMMessage.createLocationSendMessage(latitude, longitude, locationAddress, toChatUsername);    message.setAttribute("headurl",getHearurl());    message.setAttribute("userNickname",getUserNickname());    sendMessage(message);}protected void sendVideoMessage(String videoPath, String thumbPath, int videoLength) {    EMMessage message = EMMessage.createVideoSendMessage(videoPath, thumbPath, videoLength, toChatUsername);    message.setAttribute("headurl",getHearurl());    message.setAttribute("userNickname",getUserNickname());    sendMessage(message);}protected void sendFileMessage(String filePath) {    EMMessage message = EMMessage.createFileSendMessage(filePath, toChatUsername);    message.setAttribute("headurl",getHearurl());    message.setAttribute("userNickname",getUserNickname());    sendMessage(message);}

发送以后得接受显示出来，找到EaseChatRow这个类，找到方法修改即可

private void setUpBaseView() {    // set nickname, avatar and background of bubble    TextView timestamp = (TextView) findViewById(R.id.timestamp);    if (timestamp != null) {        if (position == 0) {            timestamp.setText(DateUtils.getTimestampString(new Date(message.getMsgTime())));            timestamp.setVisibility(View.VISIBLE);        } else {            // show time stamp if interval with last message is > 30 seconds            EMMessage prevMessage = (EMMessage) adapter.getItem(position - 1);            if (prevMessage != null && DateUtils.isCloseEnough(message.getMsgTime(), prevMessage.getMsgTime())) {                timestamp.setVisibility(View.GONE);            } else {                timestamp.setText(DateUtils.getTimestampString(new Date(message.getMsgTime())));                timestamp.setVisibility(View.VISIBLE);            }        }    }    if (userAvatarView != null) {        //set nickname and avatar        try {            Log.e("环信=======getFrom", message.getStringAttribute("headurl"));        } catch (HyphenateException e) {            e.printStackTrace();        }        if (message.direct() == Direct.SEND) {            try {                EaseUserUtils.setUserAvatar(context, message.getStringAttribute("headurl"), EMClient.getInstance().getCurrentUser(), userAvatarView);            } catch (HyphenateException e) {                e.printStackTrace();            }        } else {            try {                EaseUserUtils.setUserAvatar(context, message.getStringAttribute("headurl"), message.getFrom(), userAvatarView);            } catch (HyphenateException e) {                e.printStackTrace();            }            EaseUserUtils.setUserNick(message.getFrom(), usernickView);        }    }    if (deliveredView != null) {        if (message.isDelivered()) {            deliveredView.setVisibility(View.VISIBLE);        } else {            deliveredView.setVisibility(View.INVISIBLE);        }    }    if (ackedView != null) {        if (message.isAcked()) {            if (deliveredView != null) {                deliveredView.setVisibility(View.INVISIBLE);            }            ackedView.setVisibility(View.VISIBLE);        } else {            ackedView.setVisibility(View.INVISIBLE);        }    }    if (itemStyle != null) {        if (userAvatarView != null) {            if (itemStyle.isShowAvatar()) {                userAvatarView.setVisibility(View.VISIBLE);                EaseAvatarOptions avatarOptions = EaseUI.getInstance().getAvatarOptions();                if (avatarOptions != null && userAvatarView instanceof EaseImageView) {                    EaseImageView avatarView = ((EaseImageView) userAvatarView);                    if (avatarOptions.getAvatarShape() != 0)                        avatarView.setShapeType(avatarOptions.getAvatarShape());                    if (avatarOptions.getAvatarBorderWidth() != 0)                        avatarView.setBorderWidth(avatarOptions.getAvatarBorderWidth());                    if (avatarOptions.getAvatarBorderColor() != 0)                        avatarView.setBorderColor(avatarOptions.getAvatarBorderColor());                    if (avatarOptions.getAvatarRadius() != 0)                        avatarView.setRadius(avatarOptions.getAvatarRadius());                }            } else {                userAvatarView.setVisibility(View.GONE);            }        }        if (usernickView != null) {            if (itemStyle.isShowUserNick())                usernickView.setVisibility(View.VISIBLE);            else                usernickView.setVisibility(View.GONE);        }        if (bubbleLayout != null) {            if (message.direct() == Direct.SEND) {                if (itemStyle.getMyBubbleBg() != null) {                    bubbleLayout.setBackgroundDrawable(((EaseMessageAdapter) adapter).getMyBubbleBg());                }            } else if (message.direct() == Direct.RECEIVE) {                if (itemStyle.getOtherBubbleBg() != null) {                    bubbleLayout.setBackgroundDrawable(((EaseMessageAdapter) adapter).getOtherBubbleBg());                }            }        }    }}

有时候需要把头像设置成圆形，找到上面方法用到的工具类EaseUserUtils，进行修改

    public static void setUserAvatar(Context context,String hearurl, String username, ImageView imageView){       EaseUser user = getUserInfo(username);        Log.e("环信=======username",username);        Log.e("环信=======username",user+"");        //头像设置为圆形        Glide.with(context).load(hearurl)                .diskCacheStrategy(DiskCacheStrategy.RESULT)                .bitmapTransform(new CropCircleTransformation(context))                .into(imageView);    }        /**     * set user's nickname     */    public static void setUserNick(String username,TextView textView){        if(textView != null){           EaseUser user = getUserInfo(username);           if(user != null && user.getNick() != null){              textView.setText(user.getNick());           }else{              textView.setText(username);           }        }    }

到此就完成了头像，昵称的设置，接下来看点击事件

ChatFragment extends EaseChatFragment implements EaseChatFragmentHelper

在我们的这个类里实现如下方法，进行相应的点击即可

    @Override    public void onSetMessageAttributes(EMMessage message) {        Log.e("sujd==========","11111");    }    @Override    public void onEnterToChatDetails() {        Log.e("sujd==========","22222");    }    @Override    public void onAvatarClick(String username) {        Log.e("sujd==========","点击头像触发的事件");    }    @Override    public void onAvatarLongClick(String username) {        Log.e("sujd==========","44444");    }    @Override    public boolean onMessageBubbleClick(EMMessage message) {        Log.e("sujd==========","55555");        return false;    }    @Override    public void onMessageBubbleLongClick(final EMMessage message) {        Log.e("sujd==========","消息框长按事件");    }    @Override    public boolean onExtendMenuItemClick(int itemId, View view) {        Log.e("sujd==========","77777");        return false;    }    @Override    public EaseCustomChatRowProvider onSetCustomChatRowProvider() {        Log.e("sujd==========","88888");        return null;    }}
