? ? ? ?其實我接觸android時間也不是很久，但是發現android遠遠比我們想象的要有趣并且復雜很多，所以還是要多花點時間來寫一寫這些demo例子，這個程序是我從慕課網上學來的，因為畢竟要自己手寫，才能體會到程序的完整性，所以我還是建議大家自己手寫代碼，大部分代碼我已經添加了注釋，如果有疑問，大家一起來討論討論。

效果圖

主布局文件

<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"tools:context="com.example.weixin_record.MainActivity" ><ListViewandroid:id="@+id/listview"android:layout_width="match_parent"android:layout_height="0dp"android:layout_weight="1"android:background="#ebebeb"android:divider="@null"android:dividerHeight="10dp" ></ListView><FrameLayoutandroid:layout_width="match_parent"android:layout_height="wrap_content" ><!-- minHeight消除主界面上的一些間距 --><com.nickming.view.AudioRecordButtonandroid:id="@+id/recordButton"android:layout_width="match_parent"android:layout_height="wrap_content"android:layout_marginBottom="7dp"android:layout_marginLeft="50dp"android:layout_marginRight="50dp"android:layout_marginTop="6dp"android:background="@drawable/button_recordnormal"android:gravity="center"android:minHeight="0dp"android:padding="5dp"android:text="@string/normal"android:textColor="#727272" ></com.nickming.view.AudioRecordButton><Viewandroid:layout_width="match_parent"android:layout_height="1dp"android:background="#ccc" /></FrameLayout></LinearLayout>

listview的item布局文件

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

新建文件夾drawable，并創立這些自定義資源文件

button加載時樣式的文件

<?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 --><strokeandroid:width="1px"android:color="#9b9b9b" /> <!-- 邊框設置 --><corners android:radius="3dp" /> <!-- 轉角 --></shape>

button正常樣式文件

<?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 --><strokeandroid:width="1px"android:color="#9b9b9b" /> <!-- 邊框設置 --><corners android:radius="3dp" /> <!-- 轉角 --></shape>

播放時的幀動畫文件

<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android" ><itemandroid:drawable="@drawable/v_anim1"android:duration="300"></item><itemandroid:drawable="@drawable/v_anim2"android:duration="300"></item><itemandroid: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 說話</string><string  name="recording">松開 結束</string><string  name="want_to_cancle">松開手指，取消發送</string><string name="shouzhishanghua">手指上滑，取消發送</string><string name="tooshort">錄音時間過短</string></resources>

style.xml,這個主要改變了對話框的樣式

<resources xmlns:android="http://schemas.android.com/apk/res/android"><!--Base application theme, dependent on API level. This theme is replacedby 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 inres/values-vXX/styles.xml, while customizations related tobackward-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><!-- 設置彈出窗口的屬性，frame疊加，isfloat是否浮動，tarnslucent是否半透明，dim是背景是否變暗 --><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>

對了，要記得在mainfest中添加幾個權限

<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" />
