Track audio recording in android
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
// 5 Minutes = 300000 Milliseconds
recorder.setMaxDuration(300000);
recorder.setAudioEncoder(MediaRecorder.Audio开发者_如何学CEncoder.AMR_NB);
recorder.setOutputFile(path);
recorder.prepare();
recorder.start();
This is my code for recording an audio..
I need to track the time at each seconds to show the recorded time like 00:05
. I Have given a time limit of 5minutes.
Thanks Jim Blackler I got it :).
I tried Updating the UI from a Timer
private Handler mHandler = new Handler();
...
OnClickListener mStartListener = new OnClickListener() {
public void onClick(View v) {
if (mStartTime == 0L) {
mStartTime = System.currentTimeMillis();
mHandler.removeCallbacks(mUpdateTimeTask);
mHandler.postDelayed(mUpdateTimeTask, 100);
}
}
};
private Runnable mUpdateTimeTask = new Runnable() {
public void run() {
final long start = mStartTime;
long millis = SystemClock.uptimeMillis() - start;
int seconds = (int) (millis / 1000);
int minutes = seconds / 60;
seconds = seconds % 60;
if (seconds < 10) {
mTimeLabel.setText("" + minutes + ":0" + seconds);
} else {
mTimeLabel.setText("" + minutes + ":" + seconds);
}
mHandler.postAtTime(this,
start + (((minutes * 60) + seconds + 1) * 1000));
}
};
