的Soundpool不會從其他活動中發揮過生

Question

我有這個問題，我想通過從活動一原在活動2

這裏播放的是我的代碼

活動1

package com.ze.zeggar.tewt; 

import android.content.Intent; 
import android.support.v7.app.AppCompatActivity; 
import android.os.Bundle; 

public class Main2Activity extends AppCompatActivity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main2); 

     int ThePlayedSound= R.raw.waterdrop; 

     Intent MyIntent= new Intent(this, MainActivity.class); 
       MyIntent.putExtra("key",ThePlayedSound); 
     startActivity(MyIntent); 
    } 
} 

活動2

package com.ze.zeggar.tewt; 

import android.content.Intent; 
import android.media.AudioManager; 
import android.media.SoundPool; 
import android.support.v7.app.AppCompatActivity; 
import android.os.Bundle; 
import android.view.View; 
import android.widget.Button; 

public class MainActivity extends AppCompatActivity { 
    Button button; 
    SoundPool Sound_Pool_thing; 
    int Click; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     Intent MyIntent=getIntent(); 
     int ThePlayedSound= MyIntent.getIntExtra("key", 0); 

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

     Click = Sound_Pool_thing.load(this,ThePlayedSound , 1); 

     button=(Button)findViewById(R.id.button); 
     button.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       Sound_Pool_thing.play(Click,1,1,1,0,1); 

      } 
     }); 

    } 
} 

，當我嘗試打開我的應用「不幸的是，程序my_app有停止」 應用程序崩潰 和這裏的建議後，新的崩潰日誌：

任何想法？

Answer 1

烏爾獲得資源沒有發現，因爲你不打開原始類型資源的例外正常

嘗試獲得來自資源的原始音頻文件是這樣的：關於使用MediaPlayer的類

  int ThePlayedSound = this.getResources().getIdentifier("waterdrop", "raw", getPackageName()); 

    Intent MyIntent= new Intent(this, MainActivity.class); 
      MyIntent.putExtra("key",ThePlayedSound); 
    startActivity(MyIntent); 

Answer 2

什麼？

檢查下面這段代碼：

MainActivity類別（或任何類，你要開始新的活動）

Intent intent = new Intent(this,Main2Activity.class); 
intent.putExtra("key",R.raw.waterdrop); 
startActivity(intent); 

Main2Activity（類，將播放音頻）

public class Main2Activity extends AppCompatActivity { 
@Override 
public void onCreate(@Nullable Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activitiy_main2); 
    int soundId = getIntent().getIntExtra("key",0); 

    final MediaPlayer mPlayer =new MediaPlayer(); 
    mPlayer.setAudioSessionId(soundId); 
    mPlayer.setLooping(true); 

    Button button = (Button)findViewById(R.id.button); 
    button.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      mPlayer.start(); 
     } 
    }); 
} 
} 

此代碼適用於我。

如果說，特定的構造不工作嘗試以下之一：

final MediaPlayer mPlayer =new MediaPlayer(this,soundId); 

希望它可以幫助你！
