Android錄制聲音文件（音頻）并播放
更新時(shí)間：2016年11月22日 15:27:53 作者：夜盡天明89
這篇文章主要為大家詳細(xì)介紹了Android錄制聲音文件并播放音頻文件功能,具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下
本文實(shí)例為大家分享了Android錄制音頻文件的具體代碼，供大家參考，具體內(nèi)容如下
1、這個(gè)demo中沒有對(duì)多次點(diǎn)擊同一個(gè)聲音文件做詳細(xì)處理，偶爾會(huì)有崩潰，用的時(shí)候需要注意。
2、按住錄音按鈕錄音過程中，只對(duì)豎直方向處理了一下，水平方向沒寫；
3、沒有做刪除某個(gè)聲音文件的操作，但是測試的時(shí)候?qū)崿F(xiàn)了功能，需要用到的話，在MainActivity—>onItemClick中的TODO中有詳細(xì)說明；
4、這只是個(gè)demo，如果要在項(xiàng)目中使用，先寫出demo，沒問題了，再引入項(xiàng)目，在寫成demo后，在真機(jī)上運(yùn)行的時(shí)候，如果出現(xiàn)獲取錄音權(quán)限，最好選擇“允許”，如果拒絕，可能會(huì)崩潰。
記得打開手機(jī)運(yùn)行錄音的權(quán)限
先來效果圖：
目錄結(jié)構(gòu)：
1、添加權(quán)限：
<uses-permission android:name="android.permission.RECORD_AUDIO"/> <uses-permission android:name="android.permission.WAKE_LOCK"/> <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS"/> <uses-permission android:name="android.permission.VIBRATE"/> <uses-permission android:name="android.permission.WRITE_SETTINGS"/> <uses-permission android:name="android.permission.INTERACT_ACROSS_USERS_FULL"/> <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/> <uses-permission android:name="android.permission.CALL_PHONE"/> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" />
2、新建MediaRecorderUtils，復(fù)制以下源碼：
package com.chen.voicedemo;
import android.media.MediaRecorder;

import android.util.Log;
import android.widget.ImageView;

}
/**

*/
private void init() {
recorder = new MediaRecorder();// new出MediaRecorder對(duì)象
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
// 設(shè)置MediaRecorder的音頻源為麥克風(fēng)
recorder.setOutputFormat(MediaRecorder.OutputFormat.RAW_AMR);
// 設(shè)置MediaRecorder錄制的音頻格式

// 設(shè)置MediaRecorder錄制音頻的編碼為amr.
File file = new File(Utils.IMAGE_SDCARD_MADER);
if (!file.exists()) {

}
path = Utils.IMAGE_SDCARD_MADER + Utils.getVoiceFileName() + "stock.amr";
recorder.setOutputFile(path);
// 設(shè)置錄制好的音頻文件保存路徑
try {
recorder.prepare();// 準(zhǔn)備錄制
} catch (Exception e) {

}
}
/**

*/
public void MediaRecorderStart() {
init();
try {
recorder.start();
flag = true;
if (mimageView != null) {
updateMicStatus();
}
} catch (Exception e) {
e.printStackTrace();
Log.e("chen", "錄制失敗");
}
}
/**

*/

recorder.release(); //釋放資源
flag = false;
mimageView = null;

} catch (Exception e) {

}
}
/**

*/

}
;
private final Handler mHandler = new Handler();

}
};
private int BASE = 1;
private int SPACE = 1000;// 間隔取樣時(shí)間
private boolean flag = true;
/**

*/
private void updateMicStatus() {
if (recorder != null) {
double ratio = (double) recorder.getMaxAmplitude() / BASE;
double db = 0;// 分貝
if (ratio > 1) {
db = 20 * Math.log10(ratio);
}
int i = (int) db / 10;
switch (i) {
case 1:
mimageView.setImageResource(R.drawable.rc_ic_volume_1);
break;
case 2:
mimageView.setImageResource(R.drawable.rc_ic_volume_2);
break;
case 3:
mimageView.setImageResource(R.drawable.rc_ic_volume_3);
break;
case 4:

break;
case 5:

break;
case 6:

break;
case 7:

break;
case 8:
