聊天机器人（基于android）

1.本人最近写了一个小项目关于语音聊天的，采用讯飞语音引擎和数据，看看效果

2.项目名称叫小秘书，它可以和你进行交互，可以通过语音聊天，蛮有意思的，聊天内容你也可以定制

3.如果想做这款应用，先看看我前面写的语音识别

http://www.cnblogs.com/huipengbo/p/7043384.html

4.先看清单文件

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.chat"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-permission android:name="android.permission.CAMERA"/>
    <uses-sdk
        android:minSdkVersion="14"
        android:targetSdkVersion="18" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/login_user_selected"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

5.在看布局

主界面布局

<LinearLayout 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"
    android:orientation="vertical" >

    <ListView
        android:id="@+id/lv"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"/>
    <LinearLayout android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:padding="10dp"
        android:background="@drawable/detail_btn_bg_normal">
        <Button android:layout_width="wrap_content"
            android:onClick="click"
            android:layout_height="wrap_content"
            android:background="@drawable/bt_selector"
            android:text="开始和小秘对话"
            android:padding="5dp"
            />
    </LinearLayout>

</LinearLayout>

item布局展示

<?xml version="1.0" encoding="utf-8"?>

            android:textColor="#008"
            android:textSize="18sp" />
                <ImageView
            android:id="@+id/iv"
            android:layout_width="wrap_content"
            android:src="@drawable/logo"
            android:layout_height="wrap_content"/>
    </LinearLayout>

    <RelativeLayout
        android:id="@+id/ll_down"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="30dp">

        <TextView
            android:id="@+id/tv2"
            android:layout_width="wrap_content"

            android:padding="4dp"
            android:textColor="#000"
            android:text="我"
            android:textSize="18sp" />

        <TextView
            android:id="@+id/tv3"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentRight="true"
            android:layout_below="@+id/tv2"
            android:textColor="#080"
            android:textSize="18sp" />

    </RelativeLayout>

</LinearLayout>

6.资源配置和资产配置，资产配置参考语音识别那节随笔

@2问答数据封装类

package com.example.chat;
/*

 */

    public TalkBean(String text, int imageId, boolean isAsk) {
        super();
        this.text = text;
        this.imageId = imageId;
        this.isAsk = isAsk;
    }

}

@3返回的json数据封装类

package com.example.chat;

import java.util.ArrayList;

public class VoiceBean {

    public ArrayList<WS> ws;

    public class WS{
        public ArrayList<CW> cw;

    }

    public class CW{
        public String w;//说话的文字信息
    }

}
