列表视图中的媒体播放器

Question

我在 listeview 中重现声音。我有一个自定义适配器，但它总是在我将 int 与 mp3 资源放在一起的那一行失败！ ono 肯定我 perdnto 的东西，但不知道是什么！请教如何解决？谢谢

public class Adapter_animal extends ArrayAdapter<String>  {
private final Activity context;
private final String[] animal;
private final int[] animal_id;
private MediaPlayer mp;


public Adapter_animal(Activity context, int mylist, String[] animal, int[] animal_id) {
    super(context, R.layout.mylist, animal);
    // TODO Auto-generated constructor stub
    this.context=context;
    this.animal = animal;

    this.animal_id = animal_id;
}

public View getView(final int position,View view,ViewGroup parent) {
    LayoutInflater inflater=context.getLayoutInflater();
    View rowView=inflater.inflate(R.layout.mylist, null,true);

    TextView txtTitle = (TextView) rowView.findViewById(R.id.titolo);
    txtTitle.setText(animal[position]);

    FloatingActionButton btn = (FloatingActionButton) rowView.findViewById(R.id.f1_btn);

    btn.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            stopPlaying();
            mp = MediaPlayer.create(Adapter_animal.this, animal_id);  //error in this line "cannot resolve method
            mp.start();
        }

    });











    return rowView;

};
private void stopPlaying() {
    if (mp != null) {
        mp.stop();
        mp.release();
        mp = null;
    }
}

字符串

static String[] animal={
        "animale",
        "animale2",
        "animale3",

};

static int[] animal_id={
        R.raw.a11_ovation,


};

您正在将数组传递给需要单个资源 ID 的方法...

Documentation:

public static MediaPlayer create (Context context, int resid)

Convenience method to create a MediaPlayer for a given resource id. On success, prepare() will already have been called and must not be called again.

When done with the MediaPlayer, you should call release(), to free the resources. If not released, too many MediaPlayer instances will result in an exception.

Note that since prepare() is called automatically in this method, you cannot change the audio stream type (see setAudioStreamType(int)), audio session ID (see setAudioSessionId(int)) or audio attributes (see setAudioAttributes(AudioAttributes) of the new MediaPlayer.

Parameters

context - the Context to use

resid - the raw resource id (R.raw.<something>) for the resource to use as the datasource

Returns

MediaPlayer - a MediaPlayer object, or null if creation failed
