I have a simple player.
To create a 'connection' between SeekBar and MediaPlayer and I was touched seekbar anywhere where played and Sync seekbar with player. In your opinion, where is the problem?
what can i do ?
If you have an example in this respect share it
my code:
public class MediaPlaybackActivity extends Activity implements OnClickListener {
SeekBar seek_bar;
Button play_button, pause_button;
MediaPlayer player;
Handler seekHandler = new Handler();
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
getInit();
seekUpdation();
}
public void getInit() {
seek_bar = (SeekBar) findViewById(R.id.seek_bar);
play_button = (Button) findViewById(R.id.play_button);
pause_button = (Button) findViewById(R.id.pause_button);
play_button.setOnClickListener(this);
pause_button.setOnClickListener(this);
player = MediaPlayer.create(this, R.raw.win8);
seek_bar.setMax(player.getDuration());
seek_bar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onStopTrackingTouch(SeekBar seek_bar) {
}
#Override
public void onStartTrackingTouch(SeekBar seek_bar) {
}
#Override
public void onProgressChanged(SeekBar seek_bar, int progress, boolean fromUser) {
if(player != null && fromUser){
player.seekTo(progress * 1000);
}
}
});
}
Runnable run = new Runnable() {
#Override
public void run() {
seekUpdation();
}
};
public void seekUpdation() {
seek_bar.setProgress(player.getCurrentPosition());
seekHandler.postDelayed(run, 1000);
}
#Override
public void onClick(View view) {
switch (view.getId()) {
case R.id.play_button:
player.start();
break;
case R.id.pause_button:
player.pause();
}
}}
Use the below method
AudioManager audioManager;
private int maxVolume;
private int curVolume;
/**
* To initialize the seek bar
*/
private void initialiseSeekBar() {
audioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
maxVolume = audioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC);
curVolume = audioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
mSeekBarVolume.setMax(maxVolume);
mSeekBarVolume.setProgress(curVolume);
mSeekBarVolume
.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onStopTrackingTouch(SeekBar arg0) {
}
#Override
public void onStartTrackingTouch(SeekBar arg0) {
}
#Override
public void onProgressChanged(SeekBar arg0, int arg1,
boolean arg2) {
audioManager.setStreamVolume(AudioManager.STREAM_MUSIC,
arg1, 0);
}
});
}

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.

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
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);
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
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() {
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
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'm following this guy that wrote a code that change background color based on RGB channels assigned to 3 different seekbars, so R to one sk, G to another and B to another one.
The problem is that I can't get the code to work:
private int seekR, seekG, seekB;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_color_changer);
SeekBar sbR = (SeekBar) findViewById(R.id.RedSeekBar);
SeekBar sbG = (SeekBar) findViewById(R.id.GreenSeekBar);
SeekBar sbB = (SeekBar) findViewById(R.id.BlueSeekBar);
mySeekBarChangeListener msbclR = new mySeekBarChangeListener();
mySeekBarChangeListener msbclG = new mySeekBarChangeListener();
mySeekBarChangeListener msbclB = new mySeekBarChangeListener();
sbR.setonseekBarChangeListener(msbclR);
sbG.setonseekBarChangeListener(msbclG);
sbB.setonseekBarChangeListener(msbclB);
msbclR.onprogressChanged(sbR, sbR.getProgress(), false);
msbclG.onprogressChanged(sbG, sbG.getProgress(), false);
msbclB.onprogressChanged(sbB, sbB.getProgress(), false);
}
This text give me an error almost everywhere, whatever, nothing seems to work. I just want to know why.. Do I have to set something based on that mySeekBarChangeListener? Thanks in advance!
