Android实现智能聊天机器人
最近在做项目中,突然来了灵感,要做一个聊天机器人.聊天机器人在很多大型App上都有使用,比如QQ群里的QQ小冰,淘宝京东等App上在没有人工客服之前会有机器人跟你聊天,根据你发的问题关键词,向你推荐一些答案,可以省下很多人工的时间以及减小服务器的压力。

此功能主要原理:
1.接入图灵机器人api,拼接上你输入框的消息;

2.根据api完成网络请求消息的接收与发送

3.完成布局页面

4.实现你和小洛的对话
废话不多说,直接上图和代码

一：效果图

二:注册图灵机器人,获取api

1.进入图灵机器人官网注册,已有账号的可直接登录

2.点击创建机器人

3.创建好机器人之后会得到一个ApiKey(如图所示)

4.下面就要拼接Api地址了(拼接方法如图所示)

拼接方法:http://www.tuling123.com/openapi/api?key=你自己的apikey&info=你要发送的话&userid=你自己的唯一标示（在代码中会指出）

三.下面就是具体实现的代码了

1.首先是布局文件(activity_main)

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/LinearLayout1"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <!-- transcriptMode 自动向下滚动    alwaysScroll一直向下滚动状态;   divider设置间隔线效果 ;   listSelector设置没有滑动效果 -->

    <ListView
        android:id="@+id/lv"
        android:layout_width="fill_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:divider="@null"
        android:listSelector="@android:color/transparent"
        android:transcriptMode="alwaysScroll" >
    </ListView>

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:background="#229dec"
        android:orientation="horizontal" >

        <EditText
            android:id="@+id/et_sendText"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_gravity="center_vertical"
            android:layout_marginLeft="7dp"
            android:layout_weight="1"
            android:background="@drawable/bg_edittext_selector"
            android:paddingBottom="7dp"
            android:paddingTop="7dp" />

        <Button
            android:id="@+id/btn_send"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_margin="7dp"
            android:background="@drawable/bg_button"
            android:text="发送" />
    </LinearLayout>

</LinearLayout>

2.左布局文件(leftitem)

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <TextView
        android:id="@+id/tv_time"
        android:layout_width="fill_parent"
        android:gravity="center_horizontal"
        android:layout_height="wrap_content"/>

    <ImageView
        android:id="@+id/iv"
        android:layout_width="70dp"
        android:layout_height="70dp"
        android:layout_alignParentLeft="true"
        android:layout_below="@id/tv_time"
        android:paddingLeft="10dp"
        android:paddingRight="10dp"
        android:src="@drawable/by2" />

    <TextView
        android:layout_below="@id/tv_time"
        android:layout_marginTop="10dp"
        android:layout_marginRight="10dp"
        android:layout_toRightOf="@id/iv"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:padding="10dp"
        android:id="@+id/tv"
        android:gravity="center"
        android:background="@drawable/left"/>


</RelativeLayout>

3.右布局文件(rightitem)

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"

    <TextView
        android:id="@+id/tv_time"
        android:layout_width="fill_parent"

    <ImageView
        android:id="@+id/iv"
        android:layout_width="70dp"
        android:layout_height="70dp"
        android:layout_alignParentRight="true"
        android:layout_below="@id/tv_time"
        android:paddingLeft="10dp"
        android:paddingRight="10dp"
        android:src="@drawable/by5" />
    <TextView
        android:id="@+id/tv"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/tv_time"
        android:layout_marginLeft="10dp"
        android:layout_marginTop="14dp"

        android:layout_toLeftOf="@id/iv"
        android:background="@drawable/right"
        android:gravity="center"
        android:padding="12dp" />
</RelativeLayout>

4.bg_edittext_selector.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >

    <solid android:color="#FFFFFF" />

    <corners android:radius="5dip" />

    <stroke
        android:width="1dip"
        android:color="#BDC7D8" />

</shape>

5.bg_button.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >

    <solid android:color="#80cccf" /> <!-- 背景色 -->

    <stroke
        android:width="0.01dp"
        android:color="#80cccf" />  <!-- 邊框的顏色 -->

    <corners
        android:bottomLeftRadius="5dp"
        android:bottomRightRadius="5dp"
        android:topLeftRadius="5dp"
        android:topRightRadius="5dp" />
