想了解android仿微信聊天界面语音录制功能的相关内容吗，104zz在本文为您仔细讲解Android聊天语音录制的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：android微信聊天界面,android微信语音录制,android微信文字发送,android微信语言录制UI，下面大家一起来学习吧。

本例为模仿微信聊天界面UI设计，文字发送以及语言录制UI。

1先看效果图：

第一:chat.xml设计

 <?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
 android:layout_width="fill_parent" 
 android:layout_height="fill_parent" 
 android:background="@drawable/chat_bg_default" > 
 
 <!-- 标题栏 --> 
 <RelativeLayout 
 android:id="@+id/rl_layout" 
 android:layout_width="fill_parent" 
 android:layout_height="45dp" 
 android:background="@drawable/title_bar" 
 android:gravity="center_vertical" > 
 
 <Button 
  android:id="@+id/btn_back" 
  android:layout_width="70dp" 
  android:layout_height="wrap_content" 
  android:layout_centerVertical="true" 
  android:background="@drawable/title_btn_back" 
  android:onClick="chat_back" 
  android:text="返回" 
  android:textColor="#fff" 
  android:textSize="14sp" /> 
 
 <TextView 
  android:layout_width="wrap_content" 
  android:layout_height="wrap_content" 
  android:layout_centerInParent="true" 
  android:text="白富美"

 </RelativeLayout> 
 
 <!-- 底部按钮以及 编辑框 --> 
 <RelativeLayout 
 android:id="@+id/rl_bottom" 
 android:layout_width="fill_parent" 
 android:layout_height="wrap_content" 
 android:layout_alignParentBottom="true" 
 android:background="@drawable/chat_footer_bg" > 
 
 <ImageView 
  android:id="@+id/ivPopUp" 
  android:layout_width="wrap_content" 
  android:layout_height="wrap_content" 
  android:layout_alignParentLeft="true" 
  android:layout_centerVertical="true" 
  android:layout_marginLeft="10dip" 
  android:src="@drawable/chatting_setmode_msg_btn" /> 
 
 <RelativeLayout 
  android:id="@+id/btn_bottom"

  android:layout_height="wrap_content"

  android:layout_alignParentRight="true" 
  android:layout_centerVertical="true" 
  android:layout_marginRight="10dp" 
  android:background="@drawable/chat_send_btn" 
  android:text="发送" /> 
 
  <EditText 
  android:id="@+id/et_sendmessage" 
  android:layout_width="fill_parent" 
  android:layout_height="40dp" 
  android:layout_centerVertical="true" 
  android:layout_marginLeft="10dp" 
  android:layout_marginRight="10dp" 
  android:layout_toLeftOf="@id/btn_send" 
  android:background="@drawable/login_edit_normal" 
  android:singleLine="true" 
  android:textSize="18sp" /> 
 </RelativeLayout> 
 
 <TextView 
  android:id="@+id/btn_rcd" 
  android:layout_width="fill_parent" 
  android:layout_height="40dp" 
  android:layout_alignParentRight="true"

  android:background="@drawable/chat_send_btn" 
  android:gravity="center" 
  android:text="按住说话" 
  android:visibility="gone" /> 
 </RelativeLayout> 
 
 <!-- 聊天内容 listview --> 
 <ListView 
 android:id="@+id/listview" 
 android:layout_width="fill_parent" 
 android:layout_height="fill_parent" 
 android:layout_above="@id/rl_bottom" 
 android:layout_below="@id/rl_layout" 
 android:cacheColorHint="#0000" 
 android:divider="@null" 
 android:dividerHeight="5dp"

 <!-- 录音显示UI层 --> 
 <LinearLayout 
 android:id="@+id/rcChat_popup" 
 android:layout_width="fill_parent" 
 android:layout_height="fill_parent" 
 android:gravity="center" 
 android:visibility="gone" > 
 
 <include 
  android:layout_width="wrap_content" 
  android:layout_height="wrap_content" 
  android:layout_gravity="center" 
  layout="@layout/voice_rcd_hint_window" /> 
 </LinearLayout> 
 
</RelativeLayout>

第二：语音录制类封装SoundMeter.java

package com.example.voice_rcd; 
 
import java.io.IOException; 
 
import android.media.MediaRecorder; 
import android.os.Environment; 
 
public class SoundMeter { 
 static final private double EMA_FILTER = 0.6; 
 
 private MediaRecorder mRecorder = null; 
 private double mEMA = 0.0; 
 
 public void start(String name) { 
 if (!Environment.getExternalStorageState().equals( 
  android.os.Environment.MEDIA_MOUNTED)) { 
  return; 
 } 
 if (mRecorder == null) { 
  mRecorder = new MediaRecorder(); 
  mRecorder.setAudioSource(MediaRecorder.AudioSource.MIC); 
  mRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP); 
  mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB); 
  mRecorder.setOutputFile(android.os.Environment.getExternalStorageDirectory()+"/"+name); 
  try { 
  mRecorder.prepare(); 
  mRecorder.start(); 
   
  mEMA = 0.0; 
  } catch (IllegalStateException e) { 
  System.out.print(e.getMessage()); 
  } catch (IOException e) { 
  System.out.print(e.getMessage()); 
  } 
 
 } 
 } 
 
 public void stop() { 
 if (mRecorder != null) { 
  mRecorder.stop(); 
  mRecorder.release(); 
  mRecorder = null; 
 } 
 } 
 
 public void pause() { 
 if (mRecorder != null) { 
  mRecorder.stop(); 
 } 
 } 
 
 public void start() { 
 if (mRecorder != null) { 
  mRecorder.start(); 
 } 
 } 
 
 public double getAmplitude() { 
 if (mRecorder != null) 
  return (mRecorder.getMaxAmplitude() / 2700.0); 
 else 
  return 0; 
 
 } 
 
 public double getAmplitudeEMA() { 
 double amp = getAmplitude(); 
 mEMA = EMA_FILTER * amp + (1.0 - EMA_FILTER) * mEMA; 
 return mEMA; 
 } 
}

第三：主界面Activity源码，没写太多解释，相对比较简单的自己研究下：
