こんにちは私はここで1つのゲームをやっています私は何百もの画像をギャラリーに表示する必要があります同時に画像はその画像関連のサウンドを再生する必要があることを考慮しています私は音楽再生にsounpoolを使用しています。私は正しくサウンドを再生しましたしかし、私の問題は、1つの画像を2つの画像に移動するときに、ギャラリーのスクローリングの時間にあります。そのとき、両方の画像が1つの画像、2つの画像に関連する音がその時間を重ねています。その問題を解決する方法は、誰かが私に提案してください。

mediaplayer を使用していた場合は、mp.isplaying() を使用して簡単に停止できたはずです。

しかし、私は同じ問題を抱えていましたが、1つのことを提案できます：

そこにフラグを追加すると、それを確認できます flag=true do something else do something

Ex: sound1 = mSoundPool.load(this, R.raw.abc, 1);
    mSoundPool.play(sound1, 1, 1, 1, time - 1, 1);
    loaded = true;

今、あなたがこのようにできるフラグのために

if(loaded == true)
{
    mSoundPool.stop(sound1);            
}

これを試すことができます。
