How to automate Seekbar movement with a song in Android?

How to automate Seekbar movement with a song in Android? - 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
RecyclerView.Adapter<ListViewPopulator.ViewHolder>{
List<String> musicName;
List<String> musicAdd;
Context context;
MediaPlayer mediaPlayer;
Button media_play;
Button media_stop;
SeekBar seekBar;
final Handler mhandler=new Handler();
TextView timer;
public ListViewPopulator(Activity context, List<String> musicName, List<String> musicAdd)
{
this.context=context;
this.musicName=musicName;
this.musicAdd=musicAdd;
media_play= (Button)context.findViewById(R.id.play);
media_stop=(Button)context.findViewById(R.id.pause);
seekBar= (SeekBar) context.findViewById(R.id.seekbar);
timer=(TextView) context.findViewById(R.id.timer);
}

//To fetch the location of audio files on disk
mediaPlayer=MediaPlayer.create(context, Uri.fromFile(new File(s)));
mediaPlayer.start();
//seekBar.setProgress(0);

} int temp=0;
int i=0;
#Override

I am pretty sure the logic is right and have checked the Log, the code doesn't seem to be executing. Can somebody explain why?

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

return VoiceViewHolder.createVoiceViewHolder(LayoutInflater.from(parent.getContext()).inflate(R.layout.lecture_voice_item_recycler, parent, false));

} else {

TimeUnit.MILLISECONDS.toSeconds(duration) - TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(duration)),
context.getString(R.string.sec)));
}
finalTime = duration;
seekBarDuration.setMax((int) finalTime);

} else {

}
}
};

Note: some dimensions or drawables could be lost in the example. You should use your own dimension if no compile.

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.setMax() is not updating

I code a simple music player. all works fine but when I click next button the max value of seekbar becomes the previous track's duration.though Player is working fine and music is being streamed fine but I am having trouble in setting the seekbar to work. I am assuming that seekbar is directly related to getting correct duration through getDuration. how can I solve this?
Here is my code:

I have two problems here:
is that when the current playing music finish onCompletionListener() called which is call nextButton()
which checks if shuffleBoolean and repeatBoolean states are true or not, the problem here is that when shuffleBoolean and repeatBoolean are true the SongList keeps playing serially Regardless of shuffleBoolean and repeatBoolean states, but if i pressed next or previous buttons it checks for repeatBoolean and shuffleBoolean states and play next song correctly according to the states.
sometimes when i move seekBar to any position (seconds) in the bar, the songlist stops playing at the end of current playing song
my description maybe too long for the first problem but i meant to be clear and thanks in advance.

The solution is to call next.performClick() in onCompltition() and remove all the other lines.
I don't know the reason that the firs way don't work but i thought of it as i need to call onClickListener() without clicking the button.

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.

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.

Get the progress time of the video played under videoview?

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

How to automate Seekbar movement with a song in Android? - android

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);
