Android: SeekBar volume control in a AsyncTask

Android: SeekBar volume control in a AsyncTask - android

I know how to control sound volume with a seekbar:
audioManager = (AudioManager)getSystemService(Context.AUDIO_SERVICE);
int maxVolume = audioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC);
int curVolume = audioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
SeekBar volControl = (SeekBar)findViewById(R.id.volbar);
volControl.setMax(maxVolume);
volControl.setProgress(curVolume);
volControl.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);
}
});
but.. I don't know how to do it in a AsyncTask class which show a dialog(with seekbar) while sound is playing... any ideas or examples?
thanks!

Two soundpool volume controls

I'm making a white noise app, I would like to control the volume for each sound independently. Is this possible?
Here is my onCreate at the moment.
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mySound = new SoundPool(3, AudioManager.STREAM_MUSIC, 0);
whiteNoiseId = mySound.load(this, R.raw.whitenoise, 1);
rainId = mySound.load(this, R.raw.rain, 1);
audioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
int maxVolume = audioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC);
int curVolume = audioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
SeekBar noiseVolumeControl = (SeekBar) findViewById(R.id.noiseSeekBar);
noiseVolumeControl.setMax(maxVolume);
noiseVolumeControl.setProgress(curVolume);
SeekBar rainVolumeControl = (SeekBar) findViewById(R.id.rainSeekBar);
rainVolumeControl.setMax(maxVolume);
rainVolumeControl.setProgress(curVolume);
noiseVolumeControl.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, progress, 0);
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
});
rainVolumeControl.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, progress, 0);
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
});
}
This controls just the main volume, I'd like to be able to lower one and raise the other.
Thanks!

should work with SoundPool.setVolume(int id,float leftVol,float rightVol); method. I have not tried it, but I guess it must be:
mySound.setVolume(whiteNoiseId,0.2,0.2);
mySoundPool.setVolume(rainId,0.8,0.8);

Set volume of a video of a VideoView + SeekBar as control bar

I have to set the volume of a video that is contained in a VideoView. I have to use a SeekBar(I already know how to work with SeekBars, I just would like to know how to set the volume of the video).
I also have to use another SeekBar as controll bar.
This is my code:
positionBar = (SeekBar) this.findViewById(R.id.seekBar2);
volumeBar = (SeekBar) this.findViewById(R.id.seekBar);
//getting the max volume and the current volume to set the volume bar
audioManager = (AudioManager) this.getSystemService(Context.AUDIO_SERVICE);
maxVolume = audioManager.getStreamMaxVolume(AudioManager.USE_DEFAULT_STREAM_TYPE);
currentVolume = audioManager.getStreamVolume(AudioManager.USE_DEFAULT_STREAM_TYPE);
volumeBar.setMax(maxVolume);
volumeBar.setProgress(currentVolume);
//putting the video to execute in the video view
videoPlayer.setVideoPath("android.resource://" + getPackageName() + "/" + R.raw.video);
//volume bar listener
volumeBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, int i, boolean b) {
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
});
//********************************************************************
//position bar listener
positionBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, int i, boolean b) {
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
});
//********************************************************************
//timer to update the position bar during the video execution
//and the volume
new Timer().scheduleAtFixedRate(new TimerTask() {
#Override
public void run() {
currentVolume = audioManager.getStreamVolume(AudioManager.USE_DEFAULT_STREAM_TYPE);
volumeBar.setProgress(currentVolume);
}
}, 0 , 500);
//********************************************************************

Check Below Code, To set the volume of the video programatically.
SeekBar volumeBar;
int volumeLevel;
AudioManager audioManager;
ImageView volumnBtn;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
.....
.....
volumeBar = (SeekBar) findViewById(R.id.volumeBar);
audioManager = (AudioManager) getSystemService(AUDIO_SERVICE);
volumeBar.setMax(audioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC));
volumeLevel = audioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
volumnBtn = (ImageView) findViewById(R.id.volumnBtn);
if (volumeLevel == 0) {
volumnBtn.setImageDrawable(getResources().getDrawable(R.drawable.volumnMute));
} else {
volumnBtn.setImageDrawable(getResources().getDrawable(R.drawable.volumnHigh));
}
iv_volumn_btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
volumeLevel = audioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
volumeBar.setProgress(volumeLevel);
if (volumeBar.getVisibility() == View.GONE) {
volumeBar.setVisibility(View.VISIBLE);
} else {
volumeBar.setVisibility(View.GONE);
}
}
});
volumeBar.setProgress(volumeLevel);
volumeBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, int i, boolean b) {
volumeLevel = i;
if (volumeLevel == 0) {
volumnBtn.setImageDrawable(getResources().getDrawable(R.drawable.volumnMute));
} else {
volumnBtn.setImageDrawable(getResources().getDrawable(R.drawable.volumnHigh));
}
audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, volumeLevel, 0);
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
volumeBar.setVisibility(View.GONE);
if (volumeLevel == 0) {
volumnBtn.setImageDrawable(getResources().getDrawable(R.drawable.volumnMute));
} else {
volumnBtn.setImageDrawable(getResources().getDrawable(R.drawable.volumnHigh));
}
}
});
}

use SeekBar.getProgress() to get value of your seekbar,and then use the value to set volume,in onProgressChanged method.

Set volume using seekbar [duplicate]

How can I accurately change the volume of my app using a seekbar without controlling the volume by the volume buttons on my android device? I have seperate function on the Volume keys on my android that's why I want to use a seekbar to control the volume. Can Anyone please help me?

It's not exactly what you're asking for, but it should definitely help you out, I think.

}
});
} catch (Exception e) {
e.printStackTrace();
}
}
sync with volume key:
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_VOLUME_UP){
seekBarSound.setProgress((seekBarSound.getProgress()+1>seekBarSound.getMax())?seekBarSound.getMax():seekBarSound.getProgress()+1);
}else if (keyCode==KeyEvent.KEYCODE_VOLUME_DOWN){
seekBarSound.setProgress((seekBarSound.getProgress()-1<0)?0:seekBarSound.getProgress()-1);
}
return super.onKeyDown(keyCode, event);
}

I added some clear notes for you so you'll understand the logics of every line good luck!

I am having problem of volume set 0 when initialize
I have fixed problem by using below code
volumeManager.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, int i, boolean b) {
if(b){
mAudioManager.setStreamVolume(AudioManager.STREAM_MUSIC, i, 0);
}
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
});

Volume Seekbar with changing Percentage text(100 % )
create a java class and paste all the below code
public class Volume_Dialog extends AppCompatDialogFragment {
private ImageView cross;
private TextView volume_no;
private SeekBar seekBar;
AudioManager audioManager;
#SuppressLint("SetTextI18n")
#NonNull
#Override
public Dialog onCreateDialog(#Nullable Bundle savedInstanceState) {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
LayoutInflater inflater = getActivity().getLayoutInflater();
View view = inflater.inflate(R.layout.volume_popup, null);
builder.setView(view);
getActivity().setVolumeControlStream(AudioManager.STREAM_MUSIC);
cross = view.findViewById(R.id.volume_cross);
volume_no = view.findViewById(R.id.volume_number);
seekBar = view.findViewById(R.id.volume_seekbar);
audioManager = (AudioManager) getContext().getSystemService(Context.AUDIO_SERVICE);
seekBar.setMax(audioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC));
seekBar.setProgress(audioManager.getStreamVolume(AudioManager.STREAM_MUSIC));
int mediavolume = audioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
int maxVol = audioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC);
double volPerc = Math.ceil((((double) mediavolume / (double) maxVol) * (double) 100));
volume_no.setText(volPerc+" %");
seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, progress, 0);
int mediavolume = audioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
int maxVol = audioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC);
double volPerc = Math.ceil((((double) mediavolume / (double) maxVol) * (double) 100));
volume_no.setText(volPerc+" %");
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
});
cross.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
dismiss();
}
});
return builder.create();
}}
Now call this java class in MainActivity in any onclick method. Thats it
Volume_Dialog volume_dialog = new Volume_Dialog();
volume_dialog.show(getSupportFragmentManager(), "popup dialog");

sync with volume key:
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_VOLUME_UP){
seekBarSound.setProgress((seekBarSound.getProgress()+1>seekBarSound.getMax())?seekBarSound.getMax():seekBarSound.getProgress()+1);
}else if (keyCode==KeyEvent.KEYCODE_VOLUME_DOWN){
seekBarSound.setProgress((seekBarSound.getProgress()-1<0)?0:seekBarSound.getProgress()-1);
}
return super.onKeyDown(keyCode, event);
}

I added some clear notes for you so you'll understand the logics of every line good luck!
MediaPlayer mediaPlayer;
AudioManager audioManager;
//start the video when clicked.
public void pButton(View view){
mediaPlayer.start();
}
//pause the audio when clicked.
public void pause(View view){
mediaPlayer.pause();
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//definning the audio manager as an audio service.
audioManager = (AudioManager) getSystemService(AUDIO_SERVICE);
//setting an integer with the value of the max volume of every device.
int maxVolume= audioManager.getStreamMaxVolume(audioManager.STREAM_MUSIC);
//getting the current volume.
int currentVol = audioManager.getStreamVolume(audioManager.STREAM_MUSIC);
//setting the audio at the app setup so we wont nned to write this line in every method.
mediaPlayer = MediaPlayer.create(this,R.raw.allofme);
SeekBar volumeC = (SeekBar) findViewById(R.id.volSeekBar);
//setting the limit of the seek bar from its default 100 to the device max.
volumeC.setMax(maxVolume);
//setting the current value int to match with the seek bar.
volumeC.setProgress(currentVol);
//setting a listener to check the seekbar stats at all changes.
volumeC.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
Log.i("Seek Bar change:", Integer.toString(progress));
/*setting the audio manager to stream music with the value of the current integer
from the seek bar*/
audioManager.setStreamVolume(audioManager.STREAM_MUSIC ,progress ,0);
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
});
}

I am having problem of volume set 0 when initialize
I have fixed problem by using below code
volumeManager.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, int i, boolean b) {
if(b){
mAudioManager.setStreamVolume(AudioManager.STREAM_MUSIC, i, 0);
}
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
});

Volume Seekbar with changing Percentage text(100 % )
create a java class and paste all the below code
public class Volume_Dialog extends AppCompatDialogFragment {
private ImageView cross;
private TextView volume_no;
private SeekBar seekBar;
AudioManager audioManager;
#SuppressLint("SetTextI18n")
#NonNull
#Override
public Dialog onCreateDialog(#Nullable Bundle savedInstanceState) {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
LayoutInflater inflater = getActivity().getLayoutInflater();
View view = inflater.inflate(R.layout.volume_popup, null);
builder.setView(view);
getActivity().setVolumeControlStream(AudioManager.STREAM_MUSIC);
cross = view.findViewById(R.id.volume_cross);
volume_no = view.findViewById(R.id.volume_number);
seekBar = view.findViewById(R.id.volume_seekbar);
audioManager = (AudioManager) getContext().getSystemService(Context.AUDIO_SERVICE);
seekBar.setMax(audioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC));
seekBar.setProgress(audioManager.getStreamVolume(AudioManager.STREAM_MUSIC));
int mediavolume = audioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
int maxVol = audioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC);
double volPerc = Math.ceil((((double) mediavolume / (double) maxVol) * (double) 100));
volume_no.setText(volPerc+" %");
seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, progress, 0);
int mediavolume = audioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
int maxVol = audioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC);
double volPerc = Math.ceil((((double) mediavolume / (double) maxVol) * (double) 100));
volume_no.setText(volPerc+" %");
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
});
cross.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
dismiss();
}
});
return builder.create();
}}
Now call this java class in MainActivity in any onclick method. Thats it
Volume_Dialog volume_dialog = new Volume_Dialog();
volume_dialog.show(getSupportFragmentManager(), "popup dialog");

create slider to change android volume?

Can someone give me an sample code for changing volume through a slider?
I searched and a lot of tutorials requied me to create a whole new class. Is there an easier way?
Thanks!

Add this to your OnCreate, you have to put your seekbar into the layout xml file:
audioManager = (AudioManager)getSystemService(Context.AUDIO_SERVICE);
int maxVolume = audioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC);
int curVolume = audioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
SeekBar volControl = (SeekBar)findViewById(R.id.volbar);
volControl.setMax(maxVolume);
volControl.setProgress(curVolume);
volControl.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);
}
});

Travis at the New Boston has a great Video Tutorial on this here:
http://www.youtube.com/watch?v=8sr2Y6Aff6Y
Source code for the tutorials can be found here: http://www.mybringback.com/bringers/android/thenewboston-android-series/828/thenewboston-sample-projects/

Six years later, this slightly altered version works for me in Android Studio 3.1. The IDE said I had to declare AudioManager final:
/* volume slider*/
final AudioManager audioManager = (AudioManager)getSystemService(Context.AUDIO_SERVICE);
int maxVolume = audioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC);
int curVolume = audioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
SeekBar volControl = (SeekBar)findViewById(R.id.volControl);
volControl.setMax(maxVolume);
volControl.setProgress(curVolume);
volControl.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);
}
});
//end Volume slider
