前言；正常实现聊天功能想必大家都使用三方的Sdk比如环信融云集成的，但是聊天记录的保存只能有三天，想增加保存时长就需要花钱，so 我只好自己想办法实现了，这个demo是类似于留言板，并非即时通讯！只实现了表情文字图文混排，可以通过手动刷新实现即时通讯ok废话少说，先看效果图；

大体思路：

1.先从布局开始，聊天界面就是多条目的listview，左右各算一种类型，这样正常语音，文字，图文混排，大图片，大表情，视频，都是x2倍的，聊天条目就是listview条目背景透明，然后imageview+给textview设置气泡的聊天背景

不过我现在暂时只实现了文字表情，然后键盘这块是gridview实现，写正则来过滤表情的编码，点击事件判断选中表情还是删除

感谢开源键盘控件：

https://github.com/w446108264/XhsEmoticonsKeyboard

继承XhsEmoticonsKeyboard控件写一个带表情的键盘

2.代码大体逻辑，发送的消息其实就是一个文本内容，通过SpannableStringBuilder和Spannable实现图文混排，其实就是把各种表情序列号也可以说是索引写到一个xml文件里，然后用一个map来存这些图片对应的编码，其实就是图片名字，然后通过正则来找到正确的索引，即xml里存的图片对应文件夹drawable下的

SpannableStringBuilder spannableStringBuilder = new SpannableStringBuilder(content);

Spannable spannable = QqFilter.spannableFilter(tv_content.getContext(),
        spannableStringBuilder,
        content,
        EmoticonsKeyboardUtils.getFontHeight(tv_content),
        null);
tv_content.setText(spannable);

然后就是listview的展示了，页面初始化的时候根据服务器返回的字段判断是别人发的在左边，还是我发的在右面，然后在adapter里调用图文混排的方法找到对应表情图片填充条目，发送的时候先检查是否是正确的表情字符，找到对应表情图片的集合map，找到对应的表情名字，然后和文字一起传到服务器，然后进行网络请求，上传成功之后再刷新界面，上拉加载的话是加载历史记录全部的，下拉刷新是请求最新的，每次请求都控制页面显示最多28条数据，也就是4页，上来初始化页面也是，然后可以通过聊完上拉不停的重复手动实现即时通讯

当然这是开玩笑了

下面上代码：

主要布局

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <fragment
    android:id="@+id/titlefragment"
    android:name="com.panghaha.it.testchatdemo.Titlefragment"
    android:layout_width="match_parent"
    android:layout_height="45dp"/>

    <!--<TextView-->
        <!--android:layout_centerInParent="true"-->
        <!--android:textSize="22sp"-->
        <!--android:text="在未来的日子里，\n努力让抛弃我的人\n始终觉得她们的决定是正确的"-->
        <!--android:layout_width="wrap_content"-->
        <!--android:layout_height="wrap_content" />-->
    <FrameLayout
        android:id="@+id/content"
        android:layout_above="@+id/bottom_navigation_bar"
        android:layout_below="@+id/titlefragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

    </FrameLayout>

    <com.ashokvarma.bottomnavigation.BottomNavigationBar
        android:id="@+id/bottom_navigation_bar"
        android:layout_gravity="bottom"
        android:layout_alignParentBottom="true"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>

</RelativeLayout>

主界面，下面四个按钮，切换四个fragment

聊天界面布局 最外层用自己继承
