1、申请权限
<uses-permission android:name=""/> <uses-permission android:name=".RECORD_AUDIO"/>
<uses-permission android:name=".WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name=".READ_EXTERNAL_STORAGE" />
2、开始录音
//开始计时录音
@SuppressLint("MissingPermission")
// @SuppressLint("ClickableViewAccessibility")
private void startRecording() {
recorder = new AudioRecord(,
RECORDER_SAMPLERATE, RECORDER_CHANNELS_SINGLE, RECORDER_AUDIO_ENCODING, bufferSize);
();
isRecording = true;
recordingThread = new Thread(new Runnable() {
@Override
public void run() {
writeAudioDataToFile();
}
}, "AudioRecorder Thread");
();
}
、、、、、、、、、、、、、、、、、、、、、、、、、、、、、、、、、、
private void writeAudioDataToFile() {
byte data[] = new byte[bufferSize];
String filename = getTempFilename();
strFileName = getTime();
("开始录音地址===== "+filename);
FileOutputStream os = null;
try {
os = new FileOutputStream(filename);
} catch (FileNotFoundException e) {
();
}
int read = 0;
if (null != os) {
while (isRecording) {
read = (data, 0, bufferSize);
if (AudioRecord.ERROR_INVALID_OPERATION != read) {
try {
(data);
} catch (IOException e) {
();
}
}
}
try {
();
} catch (IOException e) {
();
}
}
}
3、结束录音
private void stopRecording() {
if (null != recorder) {
isRecording = false;
();
();
isSend = true;
recorder = null;
recordingThread = null;
}
copyWaveFile(getTempFilename(), getFilename());
deleteTempFile();
}
4、长按录音，放起结束录音
onTouchListener = new () {
@Override
public boolean onTouch(View v, MotionEvent event) {
int iAction = ();
if (iAction == MotionEvent.ACTION_UP) {//抬起结束录音
("抬起结束录音");
if(isRecording){
isRecording = false;
stopRecording();
strFilePath = getFilename();//最终语言路径
();
(1, (getFilename(), 1));
}
}else if (iAction == MotionEvent.ACTION_DOWN){//按住开始录音
("按住开始录音");
if(!isRecording){
isRecording = true;
startRecording();
}
return true;
}
return false;
}
};
