布局：

<LinearLayout xmlns:android="/apk/res/android"xmlns:tools="/tools"android:layout_width="match_parent"android:layout_height="match_parent"android:orientation="vertical" ><ListView android:id="@+id/lv_list"android:layout_width="match_parent"android:divider="@null"android:layout_height="0dp"android:layout_weight="1" /><LinearLayout android:layout_width="match_parent"android:layout_height="wrap_content"android:background="@drawable/bottom_bar"android:gravity="center"android:orientation="vertical" ><Button android:id="@+id/button1"android:layout_width="wrap_content"android:layout_height="wrap_content"android:background="@drawable/btn_selector"android:onClick="startListen"android:text="点击开始语音识别" /></LinearLayout></LinearLayout>

listview的item布局（对话）：

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="/apk/res/android"android:layout_width="match_parent"android:layout_height="match_parent"android:padding="5dp" ><TextView android:id="@+id/tv_ask"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_alignParentRight="true"android:layout_alignParentTop="true"android:background="@drawable/asker_bubble"android:gravity="center"android:paddingLeft="10dp"android:paddingRight="15dp"android:text="提问"android:textColor="#000"android:textSize="16sp" /><LinearLayout android:id="@+id/ll_answer"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_alignParentLeft="true"android:layout_below="@+id/tv_ask"android:layout_marginTop="10dp"android:background="@drawable/answer_bubble"android:orientation="vertical"android:gravity="center_vertical"android:paddingLeft="15dp"android:paddingRight="10dp" ><TextView android:id="@+id/tv_answer"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_gravity="center_vertical"android:gravity="center"android:text="回答"android:textColor="#000"android:textSize="16sp" /><ImageView android:id="@+id/iv_pic"android:layout_width="wrap_content"android:layout_height="wrap_content"android:visibility="gone" /></LinearLayout></RelativeLayout>

TalkBean：

package com.itcast.chatrobot;//提问/回答public class TalkBean {public TalkBean(String content, int imageId, boolean isAsk) {super();this.content = content;this.imageId = imageId;this.isAsk = isAsk;}public String content;public int imageId;public boolean isAsk;//是否是提问}

voicebean：

package com.itcast.chatrobot;import java.util.ArrayList;public class VoiceBean {public ArrayList<WS> ws;public class WS {public ArrayList<CW> cw;}public class CW {public String w;}}
