In my alart dialog i want play mp3 from SDcard and update seekbar. its working fine with tha following code. But Seekbar Ontouchlistener not work, Like forward rewind mp3.
May maiin Activity:
public class MainActivity extends Activity {
private MediaPlayer mediaPlayer = new MediaPlayer();
SeekBar seekBarProgress;
ImageButton buttonPlayPause;
private int mediaFileLengthInMilliseconds;
private final Handler handler = new Handler();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button button = (Button) findViewById(R.id.button);
button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
final Dialog dialog = new Dialog(MainActivity.this);
dialog.setContentView(R.layout.popup_ringtones);
dialog.setTitle("Title...");
buttonPlayPause = (ImageButton) dialog.findViewById(R.id.play);
seekBarProgress = (SeekBar) dialog.findViewById(R.id.SeekBarTestPlay);
seekBarProgress.setProgress(0);
seekBarProgress.setMax(100);
dialog.setOnDismissListener(new DialogInterface.OnDismissListener() {
#Override
public void onDismiss(DialogInterface dialog) {
mediaPlayer.pause();
}
});
buttonPlayPause.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
try {
if (mediaPlayer.isPlaying()) {
mediaPlayer.stop();
mediaPlayer.release();
mediaPlayer = new MediaPlayer();
}
AssetFileDescriptor descriptor = getAssets().openFd("a.mp3");
mediaPlayer.setDataSource(descriptor.getFileDescriptor(), descriptor.getStartOffset(), descriptor.getLength());
descriptor.close();
mediaPlayer.prepare();
mediaPlayer.setVolume(1f, 1f);
mediaPlayer.setLooping(true);
mediaPlayer.start();
primarySeekBarProgressUpdater();
} catch (Exception e) {
e.printStackTrace();
}
mediaFileLengthInMilliseconds = mediaPlayer.getDuration();
}
});
dialog.show();
}
});
}
private void primarySeekBarProgressUpdater() {
seekBarProgress.setProgress((int)(((float)mediaPlayer.getCurrentPosition()/mediaFileLengthInMilliseconds)*100)); // This math construction give a percentage of "was playing"/"song length"
if (mediaPlayer.isPlaying()) {
Runnable notification = new Runnable() {
public void run() {
primarySeekBarProgressUpdater();
}
};
handler.postDelayed(notification,1000);
}
}
}
I want ontouch seekbar update song, How can i implement?
You have to implement setOnSeekBarChangeListener on your seekbar like this
playerSeekbar.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
#Override
public void onProgressChanged(SeekBar seekBar, int progress,
boolean fromUser) {
if (fromUser) {
mMediaPlayer.seekTo(progress);
updateTime();
}
}
});

I am working on an online radio app and I tried implementing a seek bar to it like the tunein. I gave the seekbar a max value since i could not use the MediaPlayer's .getDuration() method.
I successfully implemented it but when I try moving the seekbar it goes back to its previous position and somehow my play/pause button stops working.
HERE IS THE SUMMARISED CODE
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_radio);
handler = new Handler(); //for seekbar
seekBar = (SeekBar) findViewById(R.id.seekBar);
mediaPlayer = new MediaPlayer();
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
new PlayerTask().execute(radioLink);
playButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if (started) {
started = false;
mediaPlayer.pause();
playButton.setImageResource(R.drawable.pplay);
} else {
started = true;
mediaPlayer.start();
playButton.setImageResource(R.drawable.ppause);
}
}
});
seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, int i, boolean b) {
if(b)
{
mediaPlayer.seekTo(i);
}
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
});
}
class PlayerTask extends AsyncTask<String, Void, Boolean> {
#Override
protected Boolean doInBackground(String... strings) {
try {
mediaPlayer.setDataSource(strings[0]);
mediaPlayer.prepare();
prepared = true;
} catch (IOException e) {
e.printStackTrace();
}
return prepared;
}
#Override
protected void onPostExecute(Boolean aBoolean) {
super.onPostExecute(aBoolean);
loadingSoundtxt.setVisibility(View.GONE);
playButton.setVisibility(View.VISIBLE);
seekBar.setMax(1800000); //30mins in milliseconds
mediaPlayer.start();
changeSeekbar();
}
}
private void changeSeekbar(){
seekBar.setProgress(mediaPlayer.getCurrentPosition());
if (mediaPlayer.isPlaying())
{
runnable = new Runnable() {
#Override
public void run() {
changeSeekbar();
}
};
handler.postDelayed(runnable, 1000);
}
}
#Override
protected void onDestroy() {
super.onDestroy();
if (mediaPlayer != null) mediaPlayer.release();
}
}
I used these codes from this reference. They want to click on button to play music and then click again to stop playing. (in their comment they said it was worked for them but hanging for me)
It is work just for first time. I mean for first click the music is playing. for second click the music is stop but for third click the phone emulator show this error:
unfortunately your program has stopped.
This is my code:
public MediaPlayer mp;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btn=(Button) findViewById(R.id.btnRain);
//mp = MediaPlayer.create(this, R.raw.rain);
mp = MediaPlayer.create(MainActivity.this, R.raw.rain);
btn.setOnClickListener(new View.OnClickListener() {
#Override
//MediaPlayer mp = MediaPlayer.create(getApplicationContext(), R.raw.soundFileName);
// mp.start();
public void onClick(View v) {
if (mp.isPlaying()) {
mp.stop();
mp.release();
}
else {
mp.start();
}
}
});
}
In onCreate initialize mp as :
mp = new MediaPlayer();
The error is you are releasing the media player object mp, which destroys the object, call reset method instead of release.
if (mp.isPlaying())
{
mp.stop();
mp.reset();
}
else {
mp = MediaPlayer.create(LegalActivity.this, R.raw.free1);
mp.start();
}
use this below code for play and pause the music:
public MediaPlayer mp;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btn=(Button) findViewById(R.id.btnRain);
//mp = MediaPlayer.create(this, R.raw.rain);
mp = MediaPlayer.create(MainActivity.this, R.raw.rain);
btn.setOnClickListener(new View.OnClickListener() {
#Override
//MediaPlayer mp = MediaPlayer.create(getApplicationContext(), R.raw.soundFileName);
// mp.start();
public void onClick(View v) {
if (mp.isPlaying()) {
mp.pause();
}
else {
mp.start();
}
}
});
}

I was working in a very simple music player with a seek bar.
I could make it working but I got a problem with playing music, it doesn't work correctly every second - it backwards a while, then remain again like it's a buggy.
Here's full code:
private MediaPlayer mediaPlayer;
private Button button;
private TextView textView;
private SeekBar seek;
private Handler mHandler = new Handler();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button = (Button)findViewById(R.id.button);
textView = (TextView)findViewById(R.id.text);
seek = (SeekBar)findViewById(R.id.seek);
mediaPlayer = new MediaPlayer();
mediaPlayer = MediaPlayer.create(getApplicationContext(),R.raw.threedays);
MainActivity.this.runOnUiThread(new Runnable() {
#Override
public void run() {
if(mediaPlayer != null){
int mCurrentPosition = mediaPlayer.getCurrentPosition() / 1000;
seek.setProgress(mCurrentPosition);
}
mHandler.postDelayed(this, 1000);
}
});
seek.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
seekBar.setMax(mediaPlayer.getDuration() / 1000);
textView.setText(progress + "/" + seekBar.getMax());
mediaPlayer.seekTo(progress*1000);
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
});
mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
pause();
}
});
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (mediaPlayer.isPlaying()) {
pause();
} else {
start();
}
}
});
}
public void start(){
if(mediaPlayer!=null) {
mediaPlayer.start();
button.setText("Pause");
}
}
public void pause(){
if(mediaPlayer!=null) {
mediaPlayer.pause();
button.setText("Play");
}
}
#Override
protected void onDestroy() {
if(mediaPlayer!=null && mediaPlayer.isPlaying()) {
mediaPlayer.pause();
mediaPlayer.release();
mediaPlayer = null;
}
super.onDestroy();
}
Try this code on seek.setOnSeekBarChangeListener
#Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser)
{
seekBar.setMax(mediaPlayer.getDuration() / 1000);
textView.setText(progress + "/" + seekBar.getMax());
if(fromUser)
{
mediaPlayer.seekTo(progress*1000);
}
}
I am trying to play a song by using seek bar listener. But when I try to drag the progress bar then it is playing from beginning of the song. It need to play from that dragged position.
Here is my code:
public class MainActivity extends Activity {
private TextView prairText;
private AssetFileDescriptor descriptor;
private SeekBar seekBar;
private MediaPlayer mp = new MediaPlayer();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Keep screen active
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
findViewById(R.id.play_button).setVisibility(View.INVISIBLE);
findViewById(R.id.pauseButton).setVisibility(View.VISIBLE);
init();
// Play prayer
/*if (mp != null) {
mp.start();
}*/
seekBar.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
#Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
if (mp != null && fromUser) {
mp.seekTo(progress * 1000);
}
}
});
findViewById(R.id.play_button).setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (mp != null) {
mp.start();
final Handler mHandler = new Handler();
//Make sure you update Seekbar on UI thread
MainActivity.this.runOnUiThread(new Runnable() {
#Override
public void run() {
if(mp != null){
int mCurrentPosition = mp.getCurrentPosition() / 1000;
seekBar.setProgress(mCurrentPosition);
}
mHandler.postDelayed(this, 1000);
}
});
findViewById(R.id.play_button).setVisibility(View.INVISIBLE);
findViewById(R.id.pauseButton).setVisibility(View.VISIBLE);
}
}
});
findViewById(R.id.pauseButton).setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (mp != null) {
mp.pause();
findViewById(R.id.pauseButton).setVisibility(View.INVISIBLE);
findViewById(R.id.play_button).setVisibility(View.VISIBLE);
}
mp.pause();
}
});
findViewById(R.id.restart_button).setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (mp != null) {
mp.seekTo(0);
mp.start();
findViewById(R.id.play_button).setVisibility(View.INVISIBLE);
findViewById(R.id.pauseButton).setVisibility(View.VISIBLE);
}
}
});
private void init() {
prairText = (TextView) findViewById(R.id.prairText);
seekBar = (SeekBar) findViewById(R.id.seekBar1);
try {
descriptor = getAssets().openFd("mysong.mp3");
mp.setDataSource(descriptor.getFileDescriptor(), descriptor.getStartOffset(), descriptor.getLength());
descriptor.close();
mp.prepare();
} catch (Exception e) {
e.printStackTrace();
}
seekBar.setMax(mp.getDuration());
}
How to resolve this issue. Thanks in advance..
Here I did tricks:
Moved MediaPlayer instance to init() method
Changed this line
int mCurrentPosition = mMediaPlayer.getCurrentPosition() / 1000;
to:
int mCurrentPosition = mp.getCurrentPosition();
Changed this line
mp.seekTo(progress * 1000);
to:
mp.seekTo(progress);
Finally working Code will be:
public class MainActivity extends Activity {
private TextView prairText;
private AssetFileDescriptor descriptor;
private SeekBar seekBar;
private MediaPlayer mp;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Keep screen active
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
findViewById(R.id.play_button).setVisibility(View.INVISIBLE);
findViewById(R.id.pauseButton).setVisibility(View.VISIBLE);
init();
// Play song
if (mp != null) {
mp.start();
}
final Handler mHandler = new Handler();
//Make sure you update Seek bar on UI thread
MainActivity.this.runOnUiThread(new Runnable() {
#Override
public void run() {
if(mp != null){
int mCurrentPosition = mp.getCurrentPosition();
seekBar.setProgress(mCurrentPosition);
}
mHandler.postDelayed(this, 1000);
}
});
seekBar.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {
#Override

if (mp != null && fromUser) {
mp.seekTo(progress);
mp.start();
findViewById(R.id.play_button).setVisibility(View.INVISIBLE);
findViewById(R.id.pauseButton).setVisibility(View.VISIBLE);
}
}
});
findViewById(R.id.play_button).setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (mp != null) {
mp.start();
findViewById(R.id.play_button).setVisibility(View.INVISIBLE);
findViewById(R.id.pauseButton).setVisibility(View.VISIBLE);
}
}
});
findViewById(R.id.pauseButton).setOnClickListener(new OnClickListener() {
#Override

if (mp != null) {
mp.pause();
findViewById(R.id.pauseButton).setVisibility(View.INVISIBLE);
findViewById(R.id.play_button).setVisibility(View.VISIBLE);
}
mp.pause();
}
});
findViewById(R.id.restart_button).setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (mp != null) {
mp.seekTo(0);
mp.start();
findViewById(R.id.play_button).setVisibility(View.INVISIBLE);
findViewById(R.id.pauseButton).setVisibility(View.VISIBLE);
}
}
});
private void init() {
mp = new MediaPlayer();
mp.reset();
prairText = (TextView) findViewById(R.id.prairText);
seekBar = (SeekBar) findViewById(R.id.seekBar1);
try {
descriptor = getAssets().openFd("mysong.mp3");
mp.setDataSource(descriptor.getFileDescriptor(), descriptor.getStartOffset(), descriptor.getLength());
descriptor.close();
mp.prepare();
} catch (Exception e) {
e.printStackTrace();
}
int duration = mp.getDuration();
seekBar.setMax(duration);
}
}
Note: Don't forget to put mysong.mp3 in assets folder
I want to add a SeekBar to control my mediaplayer process, but i do not know how to add code.Please help me, and give some example in my project code!

In your design layout, add this
<SeekBar
android:id="#+id/SeekBar01"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
/>
In your onCreate() add this
seekBar = (SeekBar) findViewById(R.id.SeekBar01);
seekBar.setMax(mPlayer.getDuration());
seekBar.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {
public void onStopTrackingTouch(SeekBar seekBar) {
// TODO Auto-generated method stub
}
public void onStartTrackingTouch(SeekBar seekBar) {
// TODO Auto-generated method stub
}
public void onProgressChanged(SeekBar seekBar, int progress,
boolean fromUser) {
seekChange(seekBar, progress, fromUser);
}
});
}
// This makes the seekbar follow the music
public void startPlayProgressUpdater() {
seekBar.setProgress(mPlayer.getCurrentPosition());
if (mPlayer.isPlaying()) {
Runnable notification = new Runnable() {
public void run() {
startPlayProgressUpdater();
}
};
handler.postDelayed(notification,1000);
}else{
mPlayer.pause();
buttonPlayStop.setText(getString(R.string.play_str));
seekBar.setProgress(0);
}
}
// This is event handler thumb moving event
private void seekChange(SeekBar seekBar, int progress,
boolean fromUser){
mPlayer.seekTo(progress);
}
