Java에서 Gridview로 만든 요소에 SoundPool 객체를 어떻게 할당합니까?

Question

저는 Gridview를 통해 151 장의 사진을 표시하는 Android 앱을 만들고 있습니다. 저는 151 개의 소리를 가지고 있으며 모든 소리를 하나의 이미지에 할당하려고합니다. 그래서 이미지에 두드리는 사운드를 재생할 수 있습니다. SoundPool을 사용하고 있습니다. 이 일을 어떻게 할 수 있을지에 대한 아이디어?

package com.example.thefe.newsmartkedex; 

import android.media.AudioManager; 
import android.media.SoundPool; 
import android.support.v7.app.AppCompatActivity; 
import android.os.Bundle; 
import android.util.Log; 
import android.view.View; 
import android.widget.AdapterView; 
import android.widget.GridView; 
import android.widget.Toast; 

import static com.example.thefe.newsmartkedex.R.raw.pkmn1; 

public class MainActivity extends AppCompatActivity { 

    int pkmn1, pkmn2, pkmn3; 
    SoundPool mySoundPool = new SoundPool (1, AudioManager.STREAM_MUSIC, 0); 


    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     pkmn1 = mySoundPool.load(this, R.raw.pkmn1, 1); 
     pkmn2 = mySoundPool.load(this, R.raw.pkmn2, 1); 
     pkmn3 = mySoundPool.load(this, R.raw.pkmn3, 1); 


     GridView gridview = (GridView) findViewById(R.id.gridview); 
     gridview.setAdapter(new ImageAdapter(this)); 

     gridview.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
      public void onItemClick(AdapterView<?> parent, View v, 
           int position, long id) { 
       position += 1; //forget about this 
       Toast.makeText(MainActivity.this, "" + position, 
         Toast.LENGTH_SHORT).show(); 
       mySoundPool.play(/*???*/,1,1,1,0,1); 
      } 
     }); 
    }; 
} 

내 ImageAdapter 클래스는 다음과 같이 작동합니다

package com.example.thefe.newsmartkedex; 

import android.content.Context; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.BaseAdapter; 
import android.widget.GridView; 
import android.widget.ImageView; 

import java.util.ArrayList;

public class ImageAdapter extends BaseAdapter { 
    private Context mContext; 

    public ImageAdapter(Context c, ArrayList list) { 
     mContext = c; 
    } 

    public int getCount() { 
     return mThumbIds.length; 
    } 

    public Object getItem(int position) { 
     return null; 
    } 

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

    // create a new ImageView for each item referenced by the Adapter 
    public View getView(int position, View convertView, ViewGroup parent) { 
     ImageView imageView; 
     if (convertView == null) { 
      // if it's not recycled, initialize some attributes 
      imageView = new ImageView(mContext); 
      imageView.setLayoutParams(new GridView.LayoutParams(200, 200)); 
      imageView.setScaleType(ImageView.ScaleType.CENTER_CROP); 
      imageView.setPadding(8, 8, 8, 8); 
     } else { 
      imageView = (ImageView) convertView; 
     } 

     imageView.setImageResource(mThumbIds[position]); 
     return imageView; 
    } 

    // references to our images 
    private Integer[] mThumbIds = {

Answer 1

이 이미지에 대한 참조 및 그와 관련된 사운드를 유지하는 모델 클래스를 만듭니다. 항목을 클릭하면 객체에 해당하는 객체를 가져 와서 참조를 사용하여 SoundPool 객체를로드하고 재생합니다.

public class Item { 

    int imageId; 
    int soundID; 

    public Item(int imageId, int soundID){ 
     this.imageId = imageId; 
     this.soundID = soundID; 
    } 

    public int getImageId() { 
     return imageId; 
    } 

    public void setImageId(int imageId) { 
     this.imageId = imageId; 
    } 

    public int getSoundID() { 
     return soundID; 
    } 

    public void setSoundID(int soundID) { 
     this.soundID = soundID; 
    } 
} 

항목의 목록을 작성

,

List<Item> items = new ArrayList<Items>(); 
for(int i = 0; i < 10; i++) { 
    items.add(new Item(R.drawable.your_image_id, R.raw.your_sound_id)); 
} 

는 어댑터에이 목록을 전달합니다. ImageAdapter의 생성자를 수정해야합니다. 당신의 이미지는

gridview.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
    public void onItemClick(AdapterView<?> parent, View v, int position, long id) { 
     // your code 

     Item selectedItem = items.get(position); 
     int soundID = selectedItem.getSoundID(); 
     pkmn1 = mySoundPool.load(MainActivity.this, soundID, 1); 
     mySoundPool.play(pkmn1, 1, 1, 1, 0, 1); 
    } 
});
