Changing audio button from play to pause when clicked and vice versa

I want a play button in my app that when clicked plays the audio and changes to pause, and when the pause button is clicked the audio stops and the button changes to play again and so on. But the button is not working as expected. Please help. I'm adding my java code below.
public class surah extends AppCompatActivity {
MediaPlayer mp = new MediaPlayer();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_surah);
mp=MediaPlayer.create(surah.this, R.raw.surahkahf);
final ImageView audio = (ImageView)findViewById(R.id.btn);
audio.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(mp.isPlaying()){
mp.stop();
audio.setBackgroundResource(R.drawable.play);
try {
mp.prepare();
}catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
else {
mp.start();
audio.setImageResource(R.drawable.pause);
}
}
});
}
}

Use audio.setImageResource(R.drawable.play) instead of audio.setBackgroundResource(R.drawable.play). Use mp.pause() instead of mp.stop();

First, as aborocz mentions in comments, you probably intend to pause playback instead of stop it, so the method you want to use is pause(). In that case you would not need to prepare the MediaPlayer again, and it will start from the same place it was paused when playback is resumed.
Second, the isPlaying() method is not particularly appropriate for this purpose. There are race conditions that prevent the desired behavior. From the Android MediaPlayer documentation:
Note that the transition from the Started state to the Paused state
and vice versa happens asynchronously in the player engine. It may
take some time before the state is updated in calls to isPlaying(),
and it can be a number of seconds in the case of streamed content.
Instead, store your own boolean value.
public class surah extends AppCompatActivity {
private MediaPlayer mp;
private boolean isMediaPlaying = false;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_surah);
mp = MediaPlayer.create(surah.this, R.raw.surahkahf);
final ImageView audio = (ImageView)findViewById(R.id.btn);
audio.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (isMediaPlaying) {
mp.pause();
audio.setBackgroundResource(R.drawable.play);
isMediaPlaying = false;
} else {
mp.start();
audio.setImageResource(R.drawable.pause);
isMediaPlaying = true;
}
}
});
}
}

How make a Button on/off music android

i'am trying to develop an app in android with 2 buttons. the first button must pause and restart the music if you state is on or off. but this code doesn't works, why?
public class MainActivity extends Activity {
MediaPlayer sound;
Boolean pulsado=false;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
this.setVolumeControlStream(AudioManager.STREAM_MUSIC);
sound=MediaPlayer.create(getBaseContext(),R.raw.gaitas);
sound.setLooping(true);
sound.start();
}
public void boton1(View v){
if(pulsado==false){
sound.stop();
pulsado=true;
}else{
sound.reset();
}
}
public void boton2(View v){
Intent i=new Intent(this,ActivityB.class);
startActivity(i);
}

Android documentation says about MediaPlayer.reset() -- Resets the MediaPlayer to its uninitialized state. After calling this method, you will have to initialize it again by setting the data source and calling prepare().
For your purpose, you could use MediaPlayer.create(...) again to setDataSource to the MP and prepare it for playing.
if (pulsado == false) {
sound.stop();
sound.reset();
pulsado = true;
} else {
sound = MediaPlayer.create(getBaseContext(), R.raw.song);
sound.setLooping(true);
sound.start();
pulsado = false;
}
If you are looking for pausing the song, you could rather call sound.pause() and in else block simple sound.start() should be enough to resume the song.

Media Player start stop start

I am making a new android sound application. I made a clickable button to play sound when I click on it. But I also want it to stop playing sound when I click for the second time. That part works fine now here is the problem, when I click again on button to play sound again, it doesn't play it, Media player is completely stopped. I was looking on forums but I can't seem to find an answer that could help me.
Here is my Activity:
MediaPlayer mpButtonClick1;
MediaPlayer mpButtonClick2;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.prvi);
final MediaPlayer mpButtonClick1 = MediaPlayer.create(this, R.raw.spalshm);
final MediaPlayer mpButtonClick2 = MediaPlayer.create(this, R.raw.splashs);
Button dugme = (Button) findViewById(R.id.dugme);
dugme.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (mpButtonClick1.isPlaying()) {
mpButtonClick1.stop();
mpButtonClick1.reset();
}
else {
mpButtonClick1.start();
}
}
});
When I try to write mpButtonClick1.prepare(); I get error Unhandled Exception Type IOE exception

Try to use pause instead of stop.
Reason: if you pause the MediaPlayer, then you can resume it later. However, if you use stop, almost any other method won't work and you will have to prepare the MediaPlayer again (or create a new one).
More info: here and here
PS: don't forget to release the memory when you finish using the resources.

Try this:
You should use only one mediaplayer object
public class PlayaudioActivity extends Activity {
private MediaPlayer mp;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button b = (Button) findViewById(R.id.button1);
Button b2 = (Button) findViewById(R.id.button2);
final TextView t = (TextView) findViewById(R.id.textView1);
b.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
stopPlaying();
mp = MediaPlayer.create(PlayaudioActivity.this, R.raw.far);
mp.start();
}
});
b2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
stopPlaying();
mp = MediaPlayer.create(PlayaudioActivity.this, R.raw.beet);
mp.start();
}
});
}
private void stopPlaying() {
if (mp != null) {
mp.stop();
mp.release();
mp = null;
}
}
}

Change your class with below code:
remove reset();.
init well all components:
MediaPlayer mpButtonClick1;
MediaPlayer mpButtonClick2;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.prvi);
mpButtonClick1 = MediaPlayer.create(this, R.raw.spalshm);
mpButtonClick2 = MediaPlayer.create(this, R.raw.splashs);
Button dugme = (Button) findViewById(R.id.dugme);
dugme.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (mpButtonClick1.isPlaying()) {
mpButtonClick1.stop();
}
else {
mpButtonClick1.start();
}
}
});

You're calling mpButtonClick1.reset() after mpButtonClick1.stop() - don't do that:
if (mpButtonClick1.isPlaying()) {
mpButtonClick1.stop();
mpButtonClick1.reset(); //<--------- calling reset(), remove this line
}
The docs for reset() say:
Resets the MediaPlayer to its uninitialized state. After calling this method, you will have to initialize it again by setting the data source and calling prepare().
Remove mpButtonClick1.reset() and it should work.
Keep in mind that MediaPlayer works as a state machine, which means that if you call methods in the wrong order, you'll get problems. Please read about MediaPlayer here and here.

Hey please use following
for stop -> media player
mp.seekTo(0);
mp.pause();
again for start just call
mp.start();

In my experience when I need to play multiple times and I may need to stop one play to start another play, (like in the case of multiple buttons), I just create another player, making sure that I release the resources for the previous one. To stop just use
mediaPlayer.stop();
But for play use something like this (adapt the logging to your specific needs) to create/recreate your player:
private boolean createMediaPlayer()
{
if (mediaPlayer!=null)
{
if(mediaPlayer.isPlaying())
{
mediaPlayer.stop();
mediaPlayer.reset();
mediaPlayer.release();
mediaPlayer=null;
}
}
mediaPlayer = new MediaPlayer();
mediaPlayer.setVolume(1f, 1f);
try
{
mediaPlayer.setAudioStreamType(Interop.PRIMARY_STREAM);
mediaPlayer.setDataSource(m_soundFile);
mediaPlayer.prepare();
return true;
// Interop.logDebug(TAG + "-loadAudio: SUCCESS" + m_soundFile);
} catch (Exception e)
{
Interop.logError(TAG + "-LoadAudio for Clic Sound: audioPlayer prepare failed for current file: " + m_soundFile);
Interop.logError(TAG + "-Exception: " , e);
return false;
}
}
and than use
if (createMediaPlayer())
mediaPlayer.start();
this will ensure proper release of the resources used by the media player.

A simple solution is to Use pause instead of stop and the seek to the beginning of the song.

I know that this question is quite old but recently while learning Android, I also got stuck at this point and found a very simple solution which I'd like to share with everyone.
Instead of trying to stop or reset the media, you can just seek back to the starting position.
mediaPlayer.seekTo(0);
For reference, I am also posting my code below:
public class MainActivity extends AppCompatActivity {
MediaPlayer mp;
public void play(View view) {
mp.start();
}
public void pause(View view) {
mp.pause();
}
public void stop(View view) {
// this seeks to the beginning of the file
mp.seekTo(0);
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mp = MediaPlayer.create(this, R.raw.sample_audio);
}
}

Android button click to play music, click again to stop sound

I have a button, when I click it plays music, how to do it, when I click second time, to stop the music?
Button two = (Button)this.findViewById(R.id.button2);
final MediaPlayer mp2 = MediaPlayer.create(this, R.raw.two);
two.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
mp2.start();
}
});
Ok, this one works:
Button one = (Button)this.findViewById(R.id.button1);
final MediaPlayer mp1 = MediaPlayer.create(this, R.raw.n);
one.setOnClickListener(new OnClickListener(){
#Override
public void onClick(View v) {
if (mp1.isPlaying()) {
mp2.pause();
}
else {
mp2.start();
}
;
}});
The one with Pause above it works, but If I want to stop the music, it does not work.
Following not working:
#Override
public void onClick(View v) {
if (mp1.isPlaying()) {
mp2.stop();
}
else {
mp2.start();
}
;
}});
I get error: start called in state 0
error (-38, 0)

According to http://developer.android.com/reference/android/media/MediaPlayer.html, I suppose you could do something like this:
Button two = (Button)this.findViewById(R.id.button2);
final MediaPlayer mp2 = MediaPlayer.create(this, R.raw.two);
two.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
// If the music is playing
if(mp2.isPlaying() == true)
// Pause the music player
mp2.pause();
// If it's not playing
else
// Resume the music player
mp2.start();
}
});
You can actually write just
if(mp2.isPlaying())
instead of
if(mp2.isPlaying() == true)
It's just for the sake of understanding what is going on.

You could have a boolean check to see if it is started (and set the boolean to false) and if so stop the music, if not start it (and set the boolean to true). Something like:
public void onClick(View v)
{
if(musicPlaying == false)
{
mp2.start();
musicPlaying = true;
}
else
{
mp2.stop();
musicPlaying = false;
}
}

if(mp2.isPlaying()) {
mp2.pause();
} else {
mp2.start();
}

This is what I used to start and stop the music, you must prepare the MediaPlayer for playback. Note: this will start the music from where it stopped.Mediaplayer prepare() methodIf you are streaming music you should use prepareAsync ()
musicButton = (Button) findViewById(R.id.btn_dj_player);
musicButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (mp.isPlaying()) {//check if a song is already playing
mp.stop();
try {
mp.prepare();//get the mediaplayer reeady for playback
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}else {
mp.start();
}
}
});

If you have only one sound and you want it to start or stop with only one button than this may help .
Button button_name = (Button)this.findViewById(R.id.Your_button_id_Here);
final MediaPlayer mp = MediaPlayer.create(this, R.raw.YOur_audio_File_name_here);
button_name.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
if(mp.isPlaying())
{
mp.pause();
}
else
{
mp.start();
}
}
});

Have you tried using the seekTo() function?
Something like:
if (mp.isPlaying()) {
mp.stop();
mp.prepareAsync();
mp.seekTo(0);
} else {
mp.start();
}
}
I am just guessing here, but might be worth looking into. :-)

I accomplished this as follows:
I declared a boolean variable:
boolean isButtonClicked = false;
Then I set up an if else in a method like so:
initPlaySound()
{
if(isButtonClicked)
{
player.start();
} else{
player.stop();
}
Lastly I set up an onClick of the button within the method:
button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
isButtonClicked = !isButtonClicked;
initPlaySound();
}
});
Basically, when the button is first clicked the boolean is set to the opposite of its' current state (false to true) and the code within the if executes. Once the button is clicked again the boolean is set to the opposite again (true to false) and the sound stops.

I solved this problem in a manual way. If sound is playing, i wrapped sound into beginning(seekTo(0)), then paused the sound. If sound is already paused, only seekTo(0) is called.
public void onClick(View v) {
if(mp.isPlaying()){
mp.seekTo(0);
mp.pause();
}
else{
mp.seekTo(0);
}
} ;

Add a global variable boolean flag=false;
if(flag==false)
{
mp=MediaPlayer.create(this, R.raw.abc);
mp.start();
playbutton.setText("Pause");
flag=true;
}
else if(mp.isPlaying()&&flag==true)
{
mp.pause();
playbutton.setText("Play");
flag=false;
}
This code will work if you want to use the same button as PLAY/PAUSE in your app. Hope this helps. Add this code in the button onClick() function which you are using to play or pause.

How to PLAY/STOP mediaplayer again?

I'm using a button "music" with 2 actions PLAY and STOP , when I click for the first time the music is played , then when I click again it's stopped. However when I click for the second time all actions PLAY/ STOP don't work .
public class Home extends Activity {
boolean isMediaOn=false;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final ImageButton music=(ImageButton)findViewById(R.id.music);
final MediaPlayer sound=MediaPlayer.create(Accueil.this,R.raw.star);
music.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// play
if(isMediaOn==false)
{
System.out.println("PLAY");
sound.start();
music.setImageResource(R.drawable.music);
isMediaOn=true;
}
// stop
else
{
System.out.println("STOP");
if(sound.isPlaying()){
sound.reset();
sound.stop();
}
music.setImageResource(R.drawable.no_music);
isMediaOn=false;
}
}
});
Here is a screenshot of my logcat :

You're only allowed to call stop() when the player is in state STARTED, PREPARED, PAUSED or PLAYBACK_COMPLETE. Your reset() call is putting it back into IDLE state, causing stop() to fail.

You probably want to use pause(), as in sound.pause();
The pause() method pauses playback and maintains all other player states (such as file that's being played, location in file, etc).

In http://developer.android.com/reference/android/media/MediaPlayer.html#stop it is clearly stated that
'Once in the Stopped state, playback cannot be started until prepare() or prepareAsync() are called to set the MediaPlayer object to the Prepared state again.'
public class Home extends Activity {
boolean isMediaOn=false;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final ImageButton music=(ImageButton)findViewById(R.id.music);
final MediaPlayer sound=MediaPlayer.create(Accueil.this,R.raw.star);
music.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// play
if(isMediaOn==false)
{
System.out.println("PLAY");
try {
sound.prepare();
} catch (Exception e) {
Log.d(Settings.debug, e.toString());
}
sound.start();
music.setImageResource(R.drawable.music);
isMediaOn=true;
}
// stop
else
{
System.out.println("STOP");
if(sound.isPlaying()){
sound.reset();
sound.stop();
}
music.setImageResource(R.drawable.no_music);
isMediaOn=false;
}
}
});

Try this, hope this helps you.
final ImageButton music=(ImageButton)findViewById(R.id.music);
final MediaPlayer sound=MediaPlayer.create(Accueil.this,R.raw.star);
music.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
if(sound.isPlaying()){
sound.stop();
music.setImageResource(R.drawable.no_music);
} else {
sound.start();
music.setImageResource(R.drawable.music);
}
});
