You need to put your music to assets directory (ie. create subfolder titled 'sounds') and then list the contents of it by method:
myContext.getAssets().list(”sounds");
Then you have to attach the asset to MediaPlayer object:
mediaPlayer.setDataSource(myContext.getAssets().openFd(soundPathInAssets));
You should also see this thread (because the bit of code I presented to you would play whole directory): Play audio file from the assets directory
EDIT: Code from example project (in case of deleting file on my dropbox):
MainActivity.java
public class MainActivity extends Activity {

How to implement a viewpager like below screen shot?

This is implemented in whatsapp,how to add a view(for audio) dynamically into the view pager like this.
i have implemented working example for images but how to do that when both image and audio files were there?
Any code or working example will be much appreciated.

Activity goes here:
in OnCreate i am calling async task to get the image/record's absolute paths from server,and adding those to list as of you are seeing "bitmaps" and "bitmapUrl" on post execute im adding the below code
ViewPager viewPager = (ViewPager) findViewById(R.id.view_pager);
adapter = new download_data_adapter(context,bitmaps,bitmapUrl);
viewPager.setAdapter(adapter);

the main.xml can be
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"

>
<RelativeLayout
android:id="#+id/wrapper1"
android:layout_width="match_parent"
android:layout_height="#dimen/titlebarsize"
android:background="#color/red">
<SeekBar
android:id="#+id/progressrecord"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:background="#drawable/violetborderbox"
android:thumb="#drawable/playbtn"
android:progressDrawable="#drawable/seekbar_progress"
android:paddingLeft="35dp"
android:paddingRight="35dp"/>
</RelativeLayout>
<RelativeLayout
android:id="#+id/wrapper2"
android:layout_below="#+id/wrapper1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/violetbg"
android:orientation="vertical"
>
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:layout_marginBottom="200dp"
app:matchChildWidth="#+id/vg_cover"
/>
</RelativeLayout>
Create an xml with the following code
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:weightSum="2"
android:orientation="horizontal" >
<ImageView
android:id="#+id/imageone"
android:layout_height="match_parent"
android:layout_width="0dp"
android:layout_weight="1"
/>
</LinearLayout>
and inflate this inside your adapter class
public class ViewPagerAdapter extends PagerAdapter {
// Declare Variables
Context context;
int[] flagone;
LayoutInflater inflater;
public ViewPagerAdapter(Context context,int[] flagsone) {
this.context = context;
this.flagone = flagsone;
}
#Override
public int getCount() {
return flag.length;
}
#Override
public boolean isViewFromObject(View view, Object object) {

}
#Override
public Object instantiateItem(ViewGroup container, int position) {
// Declare Variables
ImageView imgone;
Button button;
inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View itemView = inflater.inflate(R.layout.viewpager_image, container,
false);
// Capture position and set to the TextViews
// Locate the ImageView in viewpager_item.xml
imgone = (ImageView) itemView.findViewById(R.id.imageone);
// Capture position and set to the ImageView
imgone.setImageResource(flagone[position]);
// Add viewpager_item.xml to ViewPager
((ViewPager) container).addView(itemView);
return itemView;
}
#Override
public void destroyItem(ViewGroup container, int position, Object object) {
// Remove viewpager_item.xml from ViewPager
((ViewPager) container).removeView((RelativeLayout) object);
}
}
and in activity
onCreate(){
int imagelist1={R.drawable.image1};
int imagelist2={R.drawable.image2};
ViewPagerAdapter adapter = new ViewPagerAdapter(mContext, imagelist1,imaglist2);
// Binds the Adapter to the ViewPager
myViewPager.setAdapter(adapter);

correctly displays a seekbar in custom adapter

I have a list in which each element on a player. When I click on "start" and a song starts playing strip seekbar starts moving. when click on the "stop" the song stops playing and the strip stops. But if while moving the strip I scroll list and it goes off the screen, it starts to move another strip that is on the same position in the visible area of the screen.

startPlayProgressUpdater(seek,start);
}
};
handler.postDelayed(notification, 1000);
} else {
mediaPlayer.pause();
seek.setProgress(0);
}
}
}
EDIT:
I added geter and seter in recordBean
public int getSeekPos() {
return SeekPos;
}
public void setSeekPos(int seekPos) {
SeekPos = seekPos;
}
and
holder.seekBar.setProgress(recordBeans.get(position).getSeekPos());
holder.date.setText(" " + recordBeans.get(position).getDate());
and
#Override
public void onProgressChanged(final SeekBar seekBar, final int i, boolean b) {
if (b && (Integer)seekBar.getTag()==global_position) {
// mediaPlayer.seekTo(i);
recordBeans.get(position).setSeekPos(i);
}
}
but I think it left something extra in my code

The list item is being recycled when it leaves the screen.
You could try to call this in getView:
holder.seekBar.clearFocus();

This is a tricky process, but you can do this in the following way, as I have seen that you have created a List of RecordBean class. So what you can do is you have to create a Getter Setter in RecordBean for storing the position of you SeekBar like:
public void setSeekPos(int pos) {
this.pos = pos;
}
public int getSeekPos() {
return pos;
}
In your adapter below the line
holder.date.setText(" " + recordBeans.get(position).getDate());
set the progress of seekBar like this: holder.seekBar.setProgress(recordBeans.get(position).getSeekPos());
and inside the onProgressChanged add the following line recordBeans.get(position).setSeekPos(i);
This will resolve your issue.
Please let me know if it's working or not.
Thanks
