MediaRecorder可以进行简单的录音，由于操作简单所以可以用来进行基本的录音。
下面提供一个简单的例子，记得在Mainfest文件中添加权限。
代码如下：
package com.ppmeet;
import java.io.IOException;
import android.app.Activity;
import android.graphics.PixelFormat;
import android.media.MediaRecorder;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.Window;
import android.view.WindowManager;
import android.widget.Button;

public class TestBasicAudio extends Activity {
private Button button_start;
private Button button_stop;
private MediaRecorder recorder;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().setFormat(PixelFormat.TRANSLUCENT);// 让界面横屏
requestWindowFeature(Window.FEATURE_NO_TITLE);// 去掉界面标题
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
// 重新设置界面大小
setContentView(R.layout.main);
init();
}
private void init() {
button_start = (Button) this.findViewById(R.id.start);
button_stop = (Button) this.findViewById(R.id.stop);
button_stop.setOnClickListener(new AudioListerner());
button_start.setOnClickListener(new AudioListerner());
}
class AudioListerner implements OnClickListener {
@Override
public void onClick(View v) {
if (v == button_start) {
initializeAudio();
}
if (v == button_stop) {
recorder.stop();// 停止刻录
// recorder.reset(); // 重新启动MediaRecorder.
recorder.release(); // 刻录完成一定要释放资源
// recorder = null;
}
}
private void initializeAudio() {
recorder = new MediaRecorder();// new出MediaRecorder对象
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
// 设置MediaRecorder的音频源为麦克风
recorder.setOutputFormat(MediaRecorder.OutputFormat.RAW_AMR);
// 设置MediaRecorder录制的音频格式
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
// 设置MediaRecorder录制音频的编码为amr.
recorder.setOutputFile("/sdcard/peipei.amr");
// 设置录制好的音频文件保存路径
try {
recorder.prepare();// 准备录制
recorder.start();// 开始录制
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
