SoundPoolは2つのシナリオでクラッシュします。最初のシナリオクラッシュのコード

Question

@イアンG.クリフトン私が試したサウンドプールの最初のタイプのコードはここにあります。 アクティビティをロードするボタンを押すと、プログラムは前のアクティビティに戻ります。

コードはここから始まりますが、それは転送されない以上::::::

public class SoundManager { 

    private SoundPool mSoundPool; 
    private HashMap<Integer, Integer> mSoundPoolMap; 
    private AudioManager mAudioManager; 
    private Context mContext; 


    public SoundManager() 
    { 

    } 

    public void initSounds(Context theContext) { 
     mContext = theContext; 
     mSoundPool = new SoundPool(16, AudioManager.STREAM_MUSIC, 0); 
     mSoundPoolMap = new HashMap<Integer, Integer>(); 
     mAudioManager = (AudioManager)mContext.getSystemService(Context.AUDIO_SERVICE);   
    } 

    public void addSound(int Index,int SoundID) 
    { 
     mSoundPoolMap.put(Index, mSoundPool.load(mContext, SoundID, 1)); 
    } 

    public void playSound(int index) { 

     int streamVolume = mAudioManager.getStreamVolume(AudioManager.STREAM_MUSIC); 
     mSoundPool.play(mSoundPoolMap.get(index), streamVolume, streamVolume, 1, 0, 1f); 
    } 

    public void playLoopedSound(int index) { 

     int streamVolume = mAudioManager.getStreamVolume(AudioManager.STREAM_MUSIC); 
     mSoundPool.play(mSoundPoolMap.get(index), streamVolume, streamVolume, 1, -1, 1f); 
    } 

}

Answer 1

私の問題が見つかりました。これはコードのこれらの部分には問題ありません。実際、チラグ・シャーは私の指導で答えに導いた。私は自分のコードを見て、前のアクティビティでコードの作成セクションからボタンをロックしていることがわかりました。

私は、これはOnCreateの方法が、ときに私はプライベートの部分を削除する前だった

Private Button button1; 

を持っていました。

Button button1; 

これで正常に動作します。
