Change the volume of a specif player and get its current volume

I've this class (my media player class) and I need to create 2 methods on it, one to change the volume and other to get the current volume. (I'll create a seekbar to change the player volume), ok.
public class LoopMediaPlayer {
private Context ctx = null;
private int rawId = 0;
private MediaPlayer currentPlayer = null;
private MediaPlayer nextPlayer = null;
public static LoopMediaPlayer create(Context ctx, int rawId) {
return new LoopMediaPlayer(ctx, rawId);
}
private LoopMediaPlayer(Context ctx, int rawId) {
this.ctx = ctx;
this.rawId = rawId;
currentPlayer = MediaPlayer.create(this.ctx, this.rawId);
currentPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mediaPlayer) {
currentPlayer.start();
}
});
createNextMediaPlayer();
}
private void createNextMediaPlayer() {
nextPlayer = MediaPlayer.create(ctx, rawId);
currentPlayer.setNextMediaPlayer(nextPlayer);
currentPlayer.setOnCompletionListener(onCompletionListener);
}
private MediaPlayer.OnCompletionListener onCompletionListener = new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mediaPlayer) {
mediaPlayer.release();
currentPlayer = nextPlayer;
createNextMediaPlayer();
}
};
public void stopPlayer() {
if (currentPlayer != null && currentPlayer.isPlaying()) {
currentPlayer.stop();
currentPlayer.release();
}
if (nextPlayer != null && nextPlayer.isPlaying()) {
nextPlayer.stop();
nextPlayer.release();
}
}
public void setVolume(float vol) {
//todo
currentPlayer.setVolume(vol, vol);//don't work
}
public int getVolume(){
//todo
return 0;
}
}
and my seekBar progress and listener
seekBar.setProgress(player.getVolume());//use the method that retrieve the current volume
seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, final int i, boolean b) {
runOnUiThread(new Runnable() {
#Override
public void run() {
player.setVolume(i);//use the method that change the volume
}
});
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
});
I tried mp.setVolume() but didn't change any thing. And I can't get the current volume to set like the seekbar progress before show it.
Details - All Audios are in raw file (not stream). There will be more than one player playing at same time, them will be stored so I can retrieve any of them any time, and I want to change and retrieve just the volume of a specific player not of all them at same time.
Anyone know how I should implement both this methods, 'cause I have no idea.
Thanks

Play/Pause Media Player in Texture View Surface Texture Listener

I've implemented a recycler view and each item will play video. My problem is that I need to pause/play the video when it scrolls on/off the screen.
I've implemented that when the user scrolls the video keeps playing.
I have had an issue trying to keep track of the media player when the view scrolls off screen.
I have come up with a solution and I'm hoping I can get some advice to see if may be any issues with the solution.
So I'm using a texture view to display the media player in the recycler view as videoviews aren't compatible when looking to use a recycler or customise the controller.
So in the surface texture destroyed (signalling that the view has left the screen) I pause the media player and when the surfacetexture is available (signalling the view is on screen) I check if the media player is null (as it will be when the screen first loads) if not I start the media player. Below is my video player class in where you can see my implementation.
public class CustomVideoPlayer implements TextureView.SurfaceTextureListener, VideoControllerView.MediaPlayerControl, MediaPlayer.OnBufferingUpdateListener, MediaPlayer.OnCompletionListener, MediaPlayer.OnPreparedListener, MediaPlayer.OnVideoSizeChangedListener {

Playing audio file in android

I got stuck with one requirement i need to play a media file in android.I will post the screen shot of the page
Actual requirement is the user wants to play the audio file in his recordings list.The recordings list are shown through list adapter.I want to display the play progress of the audio file on the same page(as like shown in the screen shot).
Iam pasting the code which i have tried.
public class RecordingActivity extends ListActivity implements MediaPlayerControl {
MediaPlayer mMediaPlayer;
MediaController mMediaController;
Handler mHandler;
String OUTPUT_FILE;
RelativeLayout rl;
Context context = null;
Point p;
static final String[] recordings = new String[] {"Example1","Example2",
"Example3","Example4","Example5" };
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setListAdapter(new FirstAdapter(this, recordings));
}
#Override
protected void onListItemClick(ListView l, View v, int position, long id) {
showPopup(RecordingActivity.this, p);
// get selected items
mMediaPlayer = new MediaPlayer();
mMediaController = new MediaController(this);
mHandler = new Handler();
mMediaController.setMediaPlayer(RecordingActivity.this);
OUTPUT_FILE = Environment.getExternalStorageDirectory()+"/recorder.mp3";
try{
mMediaPlayer.setDataSource(OUTPUT_FILE);
mMediaPlayer.prepare();
}
catch(Exception e){
}
mMediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {

The problem am facing is i am able to play the audio file ,but it is not showing any popup layout.

Media player
MediaPlayer mp = new MediaPlayer();
// Set data source -
setDataSource("/sdcard/path_to_song");
// Play audio
mp.start();
// Pause audio
mp.pause();
// Reset mediaplayer
mp.reset();
// Get song length duration - in milliseconds
mp.getDuration();
// Get current duration - in milliseconds
mp.getCurrentDuration();
// Move song to particular second - used for Forward or Backward
mp.seekTo(positon); // position in milliseconds
// Check if song is playing or not
mp.isPlaying(); // returns true or false
Hope this will give you some solution. Refer this link. It will solve your problem

#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mMediaPlayer = new MediaPlayer();
mMediaController = new MediaController(this);
mMediaController.setMediaPlayer(PlayAudioActivity.this);
mMediaController.setAnchorView(findViewById(R.id.audioView));
String audioFile = "" ;
try {
mMediaPlayer.setDataSource(audioFile);
mMediaPlayer.prepare();
} catch (IOException e) {
System.out.println("Error in playing audio");
}
mMediaPlayer.setOnPreparedListener(new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mHandler.post(new Runnable() {
public void run() {
mMediaController.show(10000);
mMediaPlayer.start();
}
});
}
});
}
if you have done this then.

android: onSeekCompleteListener with VideoView

I am using VideoView to play video files. I am using seekTo function in order to play the video from where it has been left off. However, I wanted to do some operations when the seek operation is finished. For that I need to use onSeekCompleteListener; however, onSeekCompleteListener is not supported with VideoView; it can be used with MediaPlayer. My Question is that "is there any way by which I can use onSeekCompleteListener" with VideoView?
Thanks alot

There is no need to create a custom VideoView.
You can access the MediaPlayer from the onPrepared method of the VideoView and then set the OnSeekCompleteListener, like this :
mVideoView.setOnPreparedListener(new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp.setOnSeekCompleteListener(new OnSeekCompleteListener() {
#Override
public void onSeekComplete(MediaPlayer mp) {
//TODO: Your code here
}
});
}
});

public class ObservableVideoView extends VideoView
{
private IVideoViewActionListener mVideoViewListener;
private boolean mIsOnPauseMode = false;
public interface IVideoViewActionListener
{
void onPause();
void onResume();
void onTimeBarSeekChanged(int currentTime);
}
public void setVideoViewListener(IVideoViewActionListener listener)
{
mVideoViewListener = listener;
}
#Override
public void pause()
{
super.pause();
if (mVideoViewListener != null)
{
mVideoViewListener.onPause();
}
mIsOnPauseMode = true;
}
#Override
public void start()
{
super.start();
if (mIsOnPauseMode)
{
if (mVideoViewListener != null)
{
mVideoViewListener.onResume();
}
mIsOnPauseMode = false;
}
}
#Override
public void seekTo(int msec)
{
super.seekTo(msec);
if (mVideoViewListener != null)
{
mVideoViewListener.onTimeBarSeekChanged(msec);
}
}
public ObservableVideoView(Context context, AttributeSet attrs)
{
super(context, attrs);
}
public ObservableVideoView(Context context)
{
super(context);
}
public ObservableVideoView(Context context, AttributeSet attrs, int defStyle)
{
super(context, attrs, defStyle);
}
}
you can listen for events like this:
public class VideoPlayerActivity extends Activity
{
public static final String VIDEO_URL = "VideoUrl";
private String path = "";
private ObservableVideoView mVideoView;
#Override
public void onCreate(Bundle icicle)
{
super.onCreate(icicle);
setContentView(R.layout.video_player_activity_layout);
mVideoView = (ObservableVideoView) findViewById(R.id.videoView1);
mVideoView.setMediaController(new MediaController(this));
mVideoView.setVideoViewListener(mVideoViewListener);
path = getIntent().getStringExtra(VIDEO_URL);
if (path == "")
{
Toast.makeText(this, "Please edit VideoViewDemo Activity, and set path" + " variable to your media file URL/path", Toast.LENGTH_LONG)
.show();
}
else
{
mVideoView.setVideoPath(path);
mVideoView.requestFocus();
mVideoView.start();
}
}
private IVideoViewActionListener mVideoViewListener = new IVideoViewActionListener()
{
#Override
public void onTimeBarSeekChanged(int currentTime)
{
//TODO what you want
}
#Override
public void onResume()
{
//TODO what you want
}
#Override
public void onPause()
{
//TODO what you want
}
};
}

Farhan, you are correct, onSeekCompleteListener is not supported by VideoView.
But you can copy and locally customize the VideoView class to add this support yourself.
I show how to do this in my answer to 7990784.

MediaController always show on Android

I am using mediacontroller in my app, but it shows only for 3 seconds. I have searched a lot, but in every document I see only the show function, set time out, but it has no effect. How can I always show mediacontroller?
I have tested show(0), but it had no effect.

You can extend the MediaController class and programmatically set an instance of it to a VideoView class:
import android.content.Context;
import android.util.AttributeSet;
import android.widget.MediaController;
public class MyMediaController extends MediaController {
public MyMediaController(Context context, AttributeSet attrs) {
super(context, attrs);
}
public MyMediaController(Context context, boolean useFastForward) {
super(context, useFastForward);
}
public MyMediaController(Context context) {
super(context);
}
#Override
public void show(int timeout) {
super.show(0);
}
}
Here's the usage:
VideoView myVideoView = (VideoView) findViewById(R.id.my_video_view);
MediaController mc = new MyMediaController(myVideoView.getContext());
mc.setMediaPlayer(myVideoView);
myVideoView.setMediaController(mc);

You can create anonymous class inline and override certain methods. You need to override the hide method and do nothing in there. You also need to override the dispatchKeyEvent method to check for back key press and call the super.hide(). Otherwise on back press the controller wont hide and the activity cannot be closed.
mediaController = new MediaController(this){
#Override
public void hide() {
// TODO Auto-generated method stub
//do nothing
}
#Override
public boolean dispatchKeyEvent(KeyEvent event) {
if(event.getKeyCode() == KeyEvent.KEYCODE_BACK) {
if (mediaPlayer != null) {
mediaPlayer.reset();
mediaPlayer.release();
mediaPlayer = null;
}
super.hide();
Activity a = (Activity)getContext();
a.finish();
}
return true;
}
};

You can also create an anonymous class inline and override the hide method there instead of having to create a whole new class for it:
mediaController = new MediaController(this) {
#Override
public void hide() {
//Do not hide.
}
};

Try the show method in this way:
new media controller().show(50000);
And also check http://developer.android.com/reference/android/widget/MediaController.html#show().
SudeepSR: Please make a note of that, if you called show(0), it will show the Media Controller until hide() is called.

After trying all that I could, the following code worked for me!
mVideoView = (VideoView) findViewById(R.id.video);
mMediaController = new MediaController(this) {
//for not hiding
#Override
public void hide() {}
//for 'back' key action
#Override
public boolean dispatchKeyEvent(KeyEvent event) {
if(event.getKeyCode() == KeyEvent.KEYCODE_BACK) {
Activity a = (Activity)getContext();
a.finish();
}
return true;
}
};
mMediaController.setAnchorView(mVideoView);
mMediaController.setMediaPlayer(mVideoView);
mVideoView.setMediaController(mMediaController);
mMediaController.requestFocus();
//only this showed the controller for me!!
mVideoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mVideoView.start();
mMediaController.show(900000000);
}
});
//finish after playing
mVideoView.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mediaPlayer) {
finish();
}
});

What you need to do is, overrride the hide method in the custom controller and do nothing.
public class MyMediaController extends MediaController {
..
#Override
public void hide() {
// Do nothing here in order to always show
}
...
}
PS: You still need to click on the video to show the media controller.

This may be an old thread, but still unanswered, try this :
final MediaController mediaController = new MediaController(this);
mediaController.setAlwaysDrawnWithCacheEnabled(true);
mediaController.setAnchorView(vView);
mediaController.requestFocus();
vView.setOnPreparedListener( new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mediaController.show( 0 );
}
});
vView.setVideoPath(Preview_Path);
vView.setMediaController(mediaController);
vView.start();
theres a comment inside the MediaController Class "show" method
**Use 0 to show
* the controller until hide() is called**
so using 900000 or larger value wont help.
hope it helps you.
cheers.

Try this:
videoView.setOnCompletionListener(onVideoCompleted);
videoView.setOnPreparedListener(onVideoPrepared);
mc.setAnchorView(videoView);
mc.setMediaPlayer(videoView);
MediaController mc = new MediaController(this);
videoView.setMediaController(mc);
MediaPlayer.OnPreparedListener onVideoPrepared = new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mc.show(0);
}
};
MediaPlayer.OnCompletionListener onVideoCompleted = new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
mc.hide();
}
};

I wanted to fade the controller for videos and always show it for audio. This worked
mController = new MediaController(this) {
#Override
public void hide() {
if (mType != TYPE_AUDIO) super.hide();
}
#Override
public boolean dispatchKeyEvent(KeyEvent event) {
if(event.getKeyCode() == KeyEvent.KEYCODE_BACK) {
mController.hide();
Activity a = (Activity)getContext();
a.finish();
return true;
}
return false;
}
};
In MediaPlayer.onPrepared I added:
if (mType == TYPE_AUDIO) mController.show(0);
This causes the controller to show at the start of audio playback, but not video playback.
The other phone control buttons continue to work as normal.

Easy! Set visibility "GONE" in event hide and set visibility "VISIBLE" in show!
MediaController mc= new MediaController(zoom.this){
#Override
public void setMediaPlayer(MediaPlayerControl player) {
super.setMediaPlayer(player);
this.show(4000);
}
#Override
public void show(int timeout) {
super.show(timeout);
this.setVisibility(View.VISIBLE);
}
//instead of press twice with press once "back" button to back
#Override
public boolean dispatchKeyEvent(KeyEvent event) {
if(event.getKeyCode() == KeyEvent.KEYCODE_BACK) {
Activity a = (Activity)getContext();
a.finish();
}
return true;
}
#Override
public void hide() {
// TODO Auto-generated method stub
super.hide();
this.setVisibility(View.GONE);
//super.show(3000);
}
};
