在列表项上播放特定的声音，请单击

Question

I have this app where I have a listview and I would like to play a sound when an item is clicked. I tried a lot of things but none of them seem to solve my problem.

It's a listview with words, it's translation and a play button, when I click the button I want to play the sound of the specific word. Here I have my adapter and the class used. If someone knows how to answer this question I would be happy ;)

CLASS:

public class VB_Itens extends ListActivity {
        private VB_Itens_Adapter adapter;
        private int wordsArrayId, translationsArrayId;

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);

            int position = getIntent().getIntExtra("position", 0);

            // Here i populate the list with the words and it's translations from arrays resource

            switch (position) {

            case 0:
                wordsArrayId = R.array.VB_airport_words;
                translationsArrayId = R.array.VB_airport_translations;
                break;
            case 1:
                wordsArrayId = R.array.VB_hotel_words;
                translationsArrayId = R.array.VB_hotel_translations;
                break;
            case 2:
                wordsArrayId = R.array.VB_hospital_words;
                translationsArrayId = R.array.VB_hospital_translations;
                break;
            case 3:
                wordsArrayId = R.array.VB_restaurant_words;
                translationsArrayId = R.array.VB_restaurant_translations;
                break;
            }

            adapter = new VB_Itens_Adapter(this, wordsArrayId, translationsArrayId);
            setListAdapter(adapter);
        }

        @Override
        protected void onListItemClick(ListView l, View v, int position, long id) {

            // I want to play a specific sound and the item is clicked
            // I don't know how to take these sounds

        }
    }

ADAPTER:

public class VB_Itens_Adapter extends BaseAdapter {

    private List<Palavra> listaPalavras = new ArrayList<Palavra>();
    private LayoutInflater inflater;

    public VB_Itens_Adapter(Context context, int resPalavra, int resTraducao) {
        inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        String palavras[] = context.getResources().getStringArray(resPalavra);
        String traducoes[] = context.getResources().getStringArray(resTraducao);

        for (int i = 0; i < palavras.length; i++) {
            Palavra palavra = new Palavra(palavras[i], traducoes[i]);
            listaPalavras.add(palavra);
        }
    }

    @Override
    public int getCount() {
        return listaPalavras.size();
    }

    @Override
    public Object getItem(int position) {
        return listaPalavras.get(position);
    }

    @Override
    public long getItemId(int position) {
        return 0;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View view = inflater.inflate(R.layout.vb_itens, null);

        Palavra palavra = listaPalavras.get(position);

        TextView palavraView = (TextView) view.findViewById(R.id.palavra);
        TextView traducaoView = (TextView) view.findViewById(R.id.traducao);

        palavraView.setText(palavra.getPalavra());
        traducaoView.setText(palavra.getTradução());

        return view;
    }
}

You can put all your sounds in mp3 or wave format into the raw folder in the project directory, and then use the following code.

final MediaPlayer mp;
    @Override
    protected void onListItemClick(ListView l, View v, int position, long id) {
              switch (position) {
                case 0:
                    mp = MediaPlayer.create(this, R.raw.sound_of_a);
                    mp.start();
                    break;
                case 1:
                    mp = MediaPlayer.create(this, R.raw.sound_of_b);
                    mp.start();
                    break;
                case 2:
                    mp = MediaPlayer.create(this, R.raw.sound_of_c);
                    mp.start();
                    break;
                case 3:
                    mp = MediaPlayer.create(this, R.raw.sound_of_d);
                    mp.start();
                    break;
                }
    }

Hope it'll help.

I think this is what you want, the R.raw.example_sound can be placed in map( raw ) under values , if it does not exist create it yourself

MediaPlayer mediaPlayer = MediaPlayer.create(context, R.raw.example_sound);
mediaPlayer.start()

I think you have to create your own 'AccessibilityService 'and use 'TextToSpeech' to provide

spoken feedback for the users click.
