You could define a global variable for the sound effect to play:

int activeSoundEffectRawId = R.raw.defaultSound;

And play it with your SoundPool's load method.

To select the sound to play, you could add another button to your xml file that starts Activity2:

Button btnSelectSound = (Button) findViewById (R.id.button2);
btnSelectSound.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        startActivityForResult(new Intent(Activity1.this, Activity2.class), 1000);
    }
});

It's important that you start the activity for result here with the request code 1000 (this number can be changed for sure).

In your Activity 2 you need the logic to select your sound and for example a "OK" button to save the selection. That ok button will hand over the selected sound to Activity1:

Button btnOk = (Button) findViewById (R.id.ok);
btnOk.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        Intent returnIntent = new Intent();
        returnIntent.putExtra("soundRawId", selectedSoundRawId /* <- replace this with the selected sound, like R.raw.yourSound */);
        setResult(Activity.RESULT_OK,returnIntent);
        finish();
    }
});

After that, you can set the selected sound in Activity1:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == 1000 && resultCode == Activity.RESULT_OK) {
        selectedSoundRawId = data.getIntExtra("soundRawId");
    }
}

thank you so much works perfectly; but I need to do that with a RadioGroup to simplify that for the user, just select the sound and back to Activity1 ..thank you again! — Claude nix, Jun 01 '17 at 12:39
