Android仿微信语音聊天demo

       其实我接触android时间也不是很久，但是发现android远远比我们想象的要有趣并且复杂很多，所以还是要多花点时间来写一写这些demo例子，这个程序是我从慕课网上学来的，因为毕竟要自己手写，才能体会到程序的完整性，所以我还是建议大家自己手写代码，大部分代码我已经添加了注释，如果有疑问，大家一起来讨论讨论。

效果图

主布局文件

listview的item布局文件

dialog的布局样式文件

新建文件夹drawable，并创立这些自定义资源文件

button加载时样式的文件

<?xml version="1.0" encoding="utf-8"?><shape xmlns:android="http://schemas.android.com/apk/res/android" >    <solid android:color="#eeeeee" /> <!-- 背景色solid -->    <stroke        android:width="1px"        android:color="#9b9b9b" /> <!-- 边框设置 -->    <corners android:radius="3dp" /> <!-- 转角 --></shape>

button正常样式文件

<?xml version="1.0" encoding="utf-8"?><shape xmlns:android="http://schemas.android.com/apk/res/android" >    <solid android:color="#ffffff" /> <!-- 背景色solid -->    <stroke        android:width="1px"        android:color="#9b9b9b" /> <!-- 边框设置 -->    <corners android:radius="3dp" /> <!-- 转角 --></shape>

播放时的帧动画文件

<?xml version="1.0" encoding="utf-8"?><animation-list xmlns:android="http://schemas.android.com/apk/res/android" >    <item        android:drawable="@drawable/v_anim1"        android:duration="300">    </item>        <item        android:drawable="@drawable/v_anim2"        android:duration="300">    </item>        <item        android:drawable="@drawable/v_anim3"        android:duration="300">    </item></animation-list>

string.xml

<?xml version="1.0" encoding="utf-8"?><resources>    <string name="app_name">weixin_Record</string>    <string name="hello_world">Hello world!</string>    <string name="action_settings">Settings</string>    <string  name="normal">按住 说话</string>    <string  name="recording">松开 结束</string>    <string  name="want_to_cancle">松开手指，取消发送</string>    <string name="shouzhishanghua">手指上滑，取消发送</string>    <string name="tooshort">录音时间过短</string></resources>

style.xml,这个主要改变了对话框的样式

<resources xmlns:android="http://schemas.android.com/apk/res/android">    <!--        Base application theme, dependent on API level. This theme is replaced        by AppBaseTheme from res/values-vXX/styles.xml on newer devices.    -->    <style name="AppBaseTheme" parent="android:Theme.Light">        <!--            Theme customizations available in newer API levels can go in            res/values-vXX/styles.xml, while customizations related to            backward-compatibility can go here.        -->    </style>    <!-- Application theme. -->    <style name="AppTheme" parent="AppBaseTheme">        <!-- All customizations that are NOT specific to a particular API-level can go here. -->    </style>            <!-- 设置弹出窗口的属性，frame叠加，isfloat是否浮动，tarnslucent是否半透明，dim是背景是否变暗 -->    <style name="Theme_audioDialog" parent="@android:style/Theme.Dialog">        <item name="android:windowBackground">@android:color/transparent</item>        <item name="android:windowFrame">@null</item>        <item name="android:windowIsFloating">true</item>        <item name="android:windowIsTranslucent">true</item>        <item name="android:backgroundDimEnabled">false</item>    </style></resources>

对了，要记得在mainfest中添加几个权限

<uses-permission android:name="android.permission.RECORD_AUDIO" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
