loading sounds for soundPool

I have an arrayList containing resource ID's of different sounds and I need to iterate through and play all of the sound. The code I have now is not playing any of the sounds and I'm not sure why.

             for(DataClass dc : loopHolder){

                    resID = dc.getResID();
                    timeSincePrevious = dc.getTimeSincePrevious();

                    spLoop.load(getActivity(), dc.getResID(), 0);

                    spLoop.setOnLoadCompleteListener(new SoundPool.OnLoadCompleteListener() {
                    @Override
                    public void onLoadComplete(SoundPool soundPool, int mySoundId, int status) {
                        loaded = true;

                    }
                });

                    if(loaded){
                        spLoop.play(resID, 1, 1, 0, 0, 1);
                        LoopTimer timer = new LoopTimer(timeSincePrevious, 1000);
                        timer.start();
                    }
                    loaded = false;

            }
