如何將SoundPool對象分配給由Java中的Gridview創建的元素？

我正在使用Gridview顯示151張圖片的Android應用程序。我有151個聲音，我想將每個聲音分配給一個圖像，所以我可以在圖像上播放該聲音。我正在使用SoundPool。關於如何做這件事的想法？如何將SoundPool對象分配給由Java中的Gridview創建的元素？

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); 
      } 
     }); 
    }; 
}

我ImageAdapter類是這樣的：

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 = {

凡有你的作品？ –

res/drawable文件夾內，音頻在res/raw –

你有模特嗎？ –

創建保存到您的圖像的引用以及與之相關聯的聲音模型類。單擊某個項目時，獲取與該對象相對應的對象，使用該參考加載對象並播放該對象。

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; 
    } 
}

創建的項目列表，

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)); 
}

通過這個列表，您的適配器。您將修改ImageAdapter的構造函數。初始化適配器這樣的，

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

裏面你onItemClick，

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); 
    } 
});

謝謝你，優秀的答案，我會盡快回家後再試:) –

好的，我有一些麻煩。從昨晚開始我就開始工作了，我還有一些問題（原諒我，我還在學習）：首先，我得到一個煩人的「無法解決方法getSoundID（）」，我真的不知道如何要解決這個問題。其次，我不明白我必須把你寫在// Item類中的getter和setter所在的地方。最後，我在做load選項的時候遇到一個錯誤：它告訴人們「this」不能用，因爲該類型是錯誤的（預期的上下文，給定AdapterView.OnClickListener「...你可以幫我嗎？ –

檢查編輯。 –
