알람어플을 만들고있는데

알람음 설정하는 부분에서 

스피너버튼을 누르면 알람음 목록이 뜨고

그 알람음 이름을 클릭시 그 알람음이 재생되게하고싶습니다.

그리고 back키를 누를시 알람음 재생이 중단되고 스피너가 종료되게하고싶습니다.

이것저것 적어봤는데 동작하지않는군요ㅜㅜ

스피너 부분의 소스입니다.

mPool = new SoundPool(1, AudioManager.STREAM_MUSIC, 0);

mInsomnia = mPool.load(this, R.raw.insomnia,1);

mAm = (AudioManager)getSystemService(AUDIO_SERVICE);

Spinner spinner1 = (Spinner) findViewById(R.id.spinner1);

spinner1.setPrompt("알람음선택");

adapter1 = ArrayAdapter.createFromResource(this, R.array.bell, android.R.layout.simple_spinner_item);

adapter1.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

spinner1.setAdapter(adapter1);

spinner1.setOnItemSelectedListener(new OnItemSelectedListener() 

{

public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {

if (mInitSpinner == false) {

mInitSpinner = true;

return;

}

else

{

Toast.makeText(alarmadd.this, adapter1.getItem(position) + "이 설정 되었습니다.", Toast.LENGTH_SHORT).show();

MediaPlayer player;

mPool.play(mInsomnia, 1, 1, 0, 0, 1);

}

}

public void onNothingSelected(AdapterView<?> parent) {
