Get the progress time of the video played under videoview?

Get the progress time of the video played under videoview? - android

I need to get the progress time of the video that is played in "VideoView"(ie the time shown in the left hand side in progress bar).
Any help will really be appreciated.
Thanks.

You can get the Duration of the Video by mVideoView.getDuration(), set the Progress bar to 0 initially and then get the currentProgress of Video by mVideoView.getCurrentPosition(); and increase the Progress Bar status based on the CurrentProgress of Video in Percentage(%) by (current * 100 / duration). I tried it out using AsyncTask checkout this complete Example.
main.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<VideoView android:id="#+id/my_Video_View"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/hello"
/>
<ProgressBar android:layout_alignParentBottom="true"
style="#android:style/Widget.ProgressBar.Horizontal"
android:layout_width="fill_parent"
android:layout_height="10dp"
android:id="#+id/Progressbar"/>
</RelativeLayout>
VideoPlayActivity.java
public class VideoPlayActivity extends Activity {
ProgressBar mProgressBar;
VideoView mVideoView;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
String path = Environment.getExternalStorageDirectory().toString();
String filename = "/hr.3gp";
mProgressBar = (ProgressBar) findViewById(R.id.Progressbar);
mProgressBar.setProgress(0);
mProgressBar.setMax(100);
mVideoView = (VideoView) findViewById(R.id.my_Video_View);
mVideoView.setVideoURI(Uri.parse(path+filename));
new MyAsync().execute();
}
private class MyAsync extends AsyncTask<Void, Integer, Void>
{
int duration = 0;
int current = 0;
#Override
protected Void doInBackground(Void... params) {
mVideoView.start();
mVideoView.setOnPreparedListener(new OnPreparedListener() {
public void onPrepared(MediaPlayer mp) {
duration = mVideoView.getDuration();
}
});
do {
current = mVideoView.getCurrentPosition();
System.out.println("duration - " + duration + " current- "
+ current);
try {
publishProgress((int) (current * 100 / duration));
if(mProgressBar.getProgress() >= 100){
break;
}
} catch (Exception e) {
}
} while (mProgressBar.getProgress() <= 100);
return null;
}
#Override
protected void onProgressUpdate(Integer... values) {
super.onProgressUpdate(values);
System.out.println(values[0]);
mProgressBar.setProgress(values[0]);
}
}
}

You can use Thread for this purpose like below:
videoView.start();
videoView.setOnPreparedListener(new OnPreparedListener() {
public void onPrepared(MediaPlayer mp) {
running = true;
final int duration = videoView.getDuration();
new Thread(new Runnable() {
public void run() {
do{
textView.post(new Runnable() {
public void run() {
int time = (duration - videoView.getCurrentPosition())/1000;
textView.setText(time+"");
}
});
try {
Thread.sleep(500);
} catch (InterruptedException e) {
e.printStackTrace();
}
if(!running) break;
}
while(videoView.getCurrentPosition()<duration);
}
}).start();
}
});

You can use getCurrentPosition() and getDuration()to calculate the progress.

I accomplished it such way
private void playVideo() {
setViewNotVisibility();
final String videoSource = "android.resource://" + getPackageName() + File.separator + R.raw.moviiegood;
videoView.setKeepScreenOn(true);
videoView.setVideoURI(Uri.parse(videoSource));
videoView.setMediaController(null);
videoView.setOnCompletionListener(myVideoViewCompletionListener);
videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
startVideo();
setDuration();
timerCounter();
}
}
);
}
private Timer timer;
private void timerCounter(){
timer = new Timer();
TimerTask task = new TimerTask() {
#Override
public void run() {
runOnUiThread(new Runnable() {
#Override
public void run() {
updateUI();
}
});
}
};
timer.schedule(task, 0, 1000);
}
private int duration = 0;
private void setDuration(){
duration = videoView.getDuration();
}
private void updateUI(){
if (pbVideoView.getProgress() >= 100) {
timer.cancel();
}
int current = videoView.getCurrentPosition();
int progress = current * 100 / duration;
pbVideoView.setProgress(progress);
}
If you have a questions feel free to ask

SeekBar is not updating music is playing but the seekBar stay idle

I am playing mp3 file from url, but SeekBar is not updating while playing song.
It showing a buffering but not moving automatically when song starts.
When i am trying to move forcefully then also it working fine.
Below code i am using to play and update SeekBar.
I wanted to create a seekBar that track the progress of a mediaplayer but it doesnt work out quite well, the music is playing but the seekbar stay idle. Is there something that I left out?
Please help me i am new in android.
public class XYZ extends Fragment implements MediaPlayer.OnBufferingUpdateListener,MediaPlayer.OnCompletionListener{
private SeekBar seekBar;
private MediaPlayer mediaPlayer;
private int mediaFileLength;
final Handler handler = new Handler();
private int realtimeLength;
Button b,b3,b4;
private double startTime = 0;
private double finalTime = 0;
public static int oneTimeOnly = 0;
#Override
public View onCreateView(#NonNull LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_outside, container,
false);
rootView.setBackgroundResource(R.drawable.jotirling);
seekBar = rootView.findViewById(R.id.seekbar);
seekBar.setMax(99); // 100% (0~99)
seekBar.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
if (mediaPlayer.isPlaying()) {
SeekBar seekBar = (SeekBar) v;
int playPosition = (mediaFileLength / 100) * seekBar.getProgress();
mediaPlayer.seekTo(playPosition);
}
return false;
}
});
b3.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
final ProgressDialog mDialog = new ProgressDialog(getActivity());
#SuppressLint("StaticFieldLeak") AsyncTask<String, String, String> mp3Play = new AsyncTask<String, String, String>() {
#Override
protected void onPreExecute() {
mDialog.setMessage("Please wait It will take time according to your network speed...!");
mDialog.show();
mDialog.setCancelable(false);
}
#Override
protected String doInBackground(String... params) {
try {
mediaPlayer.setDataSource(params[0]);
mediaPlayer.prepare();
} catch (Exception ignored) {
}
return "";
}
#Override
protected void onPostExecute(String s) {
mediaFileLength = mediaPlayer.getDuration();
realtimeLength = mediaFileLength;
if (!mediaPlayer.isPlaying()) {
p=1;
mediaPlayer.start();
Toast.makeText(getActivity(), "Playing sound", Toast.LENGTH_SHORT).show();
finalTime = mediaPlayer.getDuration();
startTime = mediaPlayer.getCurrentPosition();
b3.setBackgroundResource(R.drawable.pp);
if (oneTimeOnly == 0) {
oneTimeOnly = 1;
}
} else {
p=0;
mediaPlayer.pause();
Toast.makeText(getActivity(), "Pausing "+
"sound",Toast.LENGTH_SHORT).show();
b3.setBackgroundResource(R.drawable.p);
}
updateSeekBar();
mDialog.dismiss();
}
};
mp3Play.execute("URL"); // direct link mp3 file
}
});
mediaPlayer = new MediaPlayer();
mediaPlayer.setOnBufferingUpdateListener(this);
mediaPlayer.setOnCompletionListener(this);
return rootView;
}
private void updateSeekBar() {
seekBar.setProgress((int) (((float) mediaPlayer.getCurrentPosition() / mediaFileLength) * 100));
if (mediaPlayer.isPlaying()) {
Runnable updater = new Runnable() {
#Override
public void run() {
updateSeekBar();
}
};
}
}
#Override
public void onBufferingUpdate(MediaPlayer mp, int percent) {
seekBar.setSecondaryProgress(percent);
}
}

You should consider using setOnSeekbarChangeListener()
Reference : setOnSeekBarChangeListener()
Simple example would be
seekBar.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
// TODO Auto-generated method stub
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
// TODO Auto-generated method stub
}
#Override
public void onProgressChanged(SeekBar seekBar, int progress,boolean fromUser) {
// TODO Auto-generated method stub
if(fromUser){
//do your things, like updating time durations etc.
}
}
});
Also if u a want working example, look at this link for code (i have just used circularSeekbar instead of regular one) https://github.com/iamSahdeep/Bop/blob/master/app/src/main/java/com/sahdeepsingh/Bop/Activities/PlayerView.java#L324
More Examples : https://www.javatips.net/api/android.widget.seekbar.onseekbarchangelistener

You can create use Timer for this:
seekBar.setMax(mediaPlayer.getDuration());
new Timer().scheduleAtFixedRate(new TimerTask() {
#Override
public void run() {
seekBar.setProgress(mediaPlayer.getCurrentPosition());
}
},0,1000);

You are defining Runnable updater but not calling it.
if (mediaPlayer.isPlaying()) {
Runnable updater = new Runnable() {
#Override
public void run() {
updateSeekBar();
}
};
seekBar.post(updater)
}

Multiple Activities with one XML File

I am making a music player application in android. The application has
MainActivity.java (with corresponding XML File:activity_main): This Activity has a listview that displays the list of all songs available.
PlayerScreen.java (with corresponding XML File:activity_player_screen): When a song is clicked on the first activity, this activity is launched and it plays that particular song. This activity has 3 Buttons (Play/Pause, NextSong, PreviousSong) and a seekbar.
Now this is where I am facing the problem
I have created a separate class (SeekBarThread.java) for implementing seekbar of the activity_player_screen using Threading.
The Problem is that when I call the start method for my thread class from PlayerScreen.java, nothing happens. No exception is thrown. The song keeps on playing but the widgets of the activity_player_screen stop working i.e. I can't pause the song aur play the next song. The seekbar also doesn't work.
I think I am not able to link the activity_player_screen file with both PlayerScreen.java and SeekBarThread.java properly.
This is the call to the Thread class from PlayerScreen.java
mySeekBarThread = new SeekBarThread(this, mySeekBar, mediaPlayer);
myThread = new Thread(mySeekBarThread);
myThread.start();
I don't really have an idea to get rid of the anomaly so I passed the seekbar object and mediaplayer object reference and the current context reference to the SeekBarThread class. But it didn't work.
Here is the SeekBarThread.java class code:
public class SeekBarThread implements Runnable{
private PlayerScreen myPlayerScreen;
private SeekBar seekBar;
private MediaPlayer mp;
private Context context;
public SeekBarThread(Context context, SeekBar seekBar, MediaPlayer mp) {
this.context = context;
this.seekBar = seekBar;
this.mp = mp;
}
public void run() {
((Activity)context).setContentView(R.layout.activity_player_screen);
seekBar.setMax(mp.getDuration());
seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
mp.seekTo(seekBar.getProgress());
}
});
int totalduration = mp.getDuration();
int currentposition = 0;
while(currentposition < totalduration) {
try {
sleep(500);
currentposition = mp.getCurrentPosition();
seekBar.setProgress(currentposition);
}
catch(InterruptedException ex) {
ex.printStackTrace();
}
}
}
}

Most of the onCreate() code for this is class is dealing with which song to play based on the user's choice from the previous activity. And since the song is being played, i don't think there is a problem in that part of the code.

#prakhar, Going through the code, I have found the following issues:
1) In SeekBarThread class in run() method setContentView() should not set,as it is already set in the activity class, as your are not reinitializing the click listeners.
2) Also the seekbarchangeListener should not be set in run() method and should be set in the main activity itself, as it doesn't need reinitalizing all the time.
3) The important point here is that your are initializing the SeekBarThread class before the initialization of MediaPlayer and hence there is no action even after seeking the seekbar.
A detailed code with the above modifications rectified.

How to automate Seekbar movement with a song in Android?

I know similar questions have been asked before but none of them could solve my problem. I'm making a music player and wish to automate the Seekbarwhen a song is played. I'm using a RecyclerViewand the following snippet exists in the onBindViewHolder section.
public class ListViewPopulator extends

In your recycler view adapter you can use something like this:

You need to use your Handler & Runnable as follows:
final Handler handler = new Handler();
final Runnable r = new Runnable() {
public void run() {
//YOUR CODE GOES HERE
handler.postDelayed(this, 1000);
}
};
handler.postDelayed(r, 0);

Found a solution for this.
Runnable runnable=new Runnable() {
#Override
public void run() {
String time;
Log.d(TAG, "run");
while(mediaPlayer != null && mediaPlayer.isPlaying()){
final int progress = mediaPlayer.getCurrentPosition();
int min = (progress / 1000) / 60;
Log.d("auto","seek");
int sec = (progress / 1000) % 60;
if (sec < 10)
time = "0" + sec;
else
time = "" + sec;
final String elapsedTime = min + ":" + time + "";
context.runOnUiThread(new Runnable() {
#Override
public void run() {
timer.setText(elapsedTime);
seekBar.setMax(mediaPlayer.getDuration());
seekBar.setProgress(progress);
}
});
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
};
new Thread(runnable).start();
The main problem here is that once mediaplayer.start() is called the media file begins loading in the player before that completes the cont_seek function is called which has the condition
if(mediaplayer!=null && mediaplayer.isplaying())
Since the media hasn't started playing yet, the condition fails and the function is never executed.
Fixed it by running the runnable in a different thread.

Seekbar doesnt play from the point where it is dragged by the user

I have the problem with the seekbar thumb, although I have added every necessary codes for it to work. still the seekbar thumb doesn't play from the point dragged by the user. instead the thumb positioned itself back to the point it was last playing though. Any help will be appreciated.

Android: SeekBar is not updated using a Handler on 4.1.2 Device

friends I am developing an application which is playing small mp3 soundtracks (podcasts). Now my code which I am showing below is working on Android 3.2 as it should. But on Android 4.1.2 the SeekBar is not being updated by the handler instance. I have read about a bug in the SeekBar causing this issue but it should be fixed since Android 3.2. Any help or advice would be appreciated. Here is my code:
public class PodcastDetailFragment extends BaseFragment {
private MediaPlayer mediaPlayer = null;
private Button playPauseButton = null;
private SeekBar seekBar = null;
private TextView timeView = null;
private int totalDuration = 0;
private Bundle data;
private Handler handler=new Handler();
private Runnable runnable = new Runnable() {
public void run() {
int progress = mediaPlayer.getCurrentPosition();
seekBar.setProgress(progress);
int hours = ((progress/1000)/60)/60;
int minutes = ((progress/1000)/60)%60;
int seconds = ((progress/1000)%60)%60;
String hoursString = (hours<10)?"0":"";
String minutesString = (minutes<10)?"0":"";
String secondsString = (seconds<10)?"0":"";
timeView.setText(hoursString+hours+":"+minutesString+minutes+":"+secondsString+seconds);
handler.postDelayed(this, 100);
}
};
public static PodcastDetailFragment newInstance(Bundle bundle) {
PodcastDetailFragment f = new PodcastDetailFragment();
f.setArguments(bundle);
return f;
}
/**

#Override

super.onActivityCreated(savedInstanceState);
}
#Override
public void onPause() {
super.onPause();
if (mediaPlayer != null) {
LogUtils.d("Podcast MediaPlayer", "stop() inside the onPause() was called");
mediaPlayer.stop();
}
}
#Override
public void onDestroy() {

mediaPlayer.release();
super.onDestroy();
}

dv.setText(data.getString("duration"));
timeView = (TextView) v.findViewById(R.id.timeView);
timeView.setText("00:00:00");

}
}
});
mediaPlayer =new MediaPlayer();
mediaPlayer
.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {

You should either use an AsyncTask or a Service (in case the music will play in background) instead of a Worker Thread with a Handler. The AsyncTask is extremely useful with it's onProgressUpdate method, you can use it to update the Bar based on the progress of the audio file.
Here's a basic example of an AsyncTask and how you should use it:
private class TestAsyncTask extends AsyncTask<Void, Integer, Void> {
#Override
protected Void doInBackground(Void... arg0) {
for(int i=0; i<songDuration; i++){
doSomething();
publishProgress(i);
}
return null;
}
#Override
protected void onProgressUpdate(Integer... progress) {
//UPDATE BAR
}
#Override
protected void onPostExecute(Void result) {
//DO SOMETHING WHEN FINISHED PLAYING
}
}
Anyway, here's the official doc: http://developer.android.com/reference/android/os/AsyncTask.html

I have solved this problem. The SeekBar was ok. It was just the issue that the lenght of a track is only given when you download the whole track. So to show the progress on a SeekBar properly you need to know the length of a track. So you take the length of a track and then call seekBar.setMax(lenghtOfTrack) and the progress is updated as it should by the method setProgress(progress).

Get the progress time of the video played under videoview? - android

I need to get the progress time of the video that is played in "VideoView"(ie the time shown in the left hand side in progress bar). Any help will really be appreciated. Thanks.

You can use getCurrentPosition() and getDuration()to calculate the progress.
