Android語音錄制的代碼

使用MediaRecorder的步驟：

1、創建MediaRecorder對象

2、調用MediRecorder對象的setAudioSource()方法設置聲音的來源，一般傳入MediaRecorder.MIC

3、調用MediaRecorder對象的setOutputFormat()設置所錄制的音頻文件的格式

4、調用MediaRecorder對象的setAudioRncoder()、setAudioEncodingBitRate(int bitRate)、setAudioSamlingRate(int SamplingRate)設置所錄音的編碼格式、編碼位率、采樣率等，

5、調用MediaRecorder對象的setOutputFile(String path)方法設置錄制的音頻文件的保存位置

6、調用MediaRecoder對象的Prepare()方法準備錄制

7、調用MediaRecoder對象的start()方法開始錄制

8、調用MediaRecoder對象的stop()方法停止錄制，并調用release()方法釋放資源

布局就不用說了 ，附上代碼吧
