环信自定义消息类型

由于工作原因，一直没时间更新博客，上个礼拜项目上线以后，今天终于可以有时间来总结下上个礼拜做的东西了：环信自定义消息类型，我们先看下效果图

要实现这样的效果，首先我们想到的是要把这些提示消息当做一个消息类型发送给对方，接下来就一步一步的去实现

第一步：自定义消息chatrow，加载的布局根据自己的需求去实现

package com.hyphenate.easeui.widget.chatrow;

import android.content.Context;
import android.text.Spannable;
import android.view.View;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.TextView;

import com.hyphenate.chat.EMClient;
import com.hyphenate.chat.EMMessage;
import com.hyphenate.chat.EMTextMessageBody;
import com.hyphenate.easeui.R;
import com.hyphenate.easeui.utils.EaseSmileUtils;
import com.hyphenate.exceptions.HyphenateException;

import android.widget.TextView.BufferType;
//自定义系统消息类型
public class EaseChatRowHint extends EaseChatRow{
    private TextView tv_chatcontent;
    private ImageView iv_userhead;
    public EaseChatRowHint(Context context, EMMessage message, int position, BaseAdapter adapter) {
        super(context, message, position, adapter);
    }

    @Override
    protected void onInflateView() {
        inflater.inflate(message.direct() == EMMessage.Direct.RECEIVE ?
                R.layout.ease_row_received_hint : R.layout.ease_row_sent_hint,this);
    }

    @Override
    protected void onFindViewById() {
        tv_chatcontent=findViewById(R.id.tv_chatcontent);
        iv_userhead=findViewById(R.id.iv_userhead);

    }

    @Override
    protected void onUpdateView() {
        adapter.notifyDataSetChanged();
    }

    @Override
    protected void onSetUpView() {
        EMTextMessageBody txtBody = (EMTextMessageBody) message.getBody();
        Spannable span = EaseSmileUtils.getSmiledText(context, txtBody.getMessage());
        // 设置内容
        tv_chatcontent.setText(span, BufferType.SPANNABLE);
        handleTextMessage();
    }
    protected void handleTextMessage() {
        if (message.direct() == EMMessage.Direct.SEND) {
            setMessageSendCallback();
            switch (message.status()) {
                case CREATE:
                    iv_userhead.setVisibility(GONE);
                    break;
                case SUCCESS:
                    iv_userhead.setVisibility(GONE);
                    break;
                case FAIL:
                    iv_userhead.setVisibility(GONE);
                    break;
                case INPROGRESS:
                    iv_userhead.setVisibility(GONE);
                    break;
                default:
                    break;
            }
        }else if (message.direct() == EMMessage.Direct.RECEIVE){
            switch (message.status()) {
                case CREATE:
                    iv_userhead.setVisibility(GONE);
                    break;
                case SUCCESS:
                    iv_userhead.setVisibility(GONE);
                    break;
                case FAIL:
                    iv_userhead.setVisibility(GONE);
                    break;
                case INPROGRESS:
                    iv_userhead.setVisibility(GONE);
                    break;
                default:
                    break;
            }
        }
    }
    @Override
    protected void onBubbleClick() {

    }
}

第二步：我们需要在EaseConstant定义一个常量来区分自己的自定义消息类型
