在所有活动中保持加载我的soundPool示例

SoundPool soundPool = new SoundPool.Builder()
    .setMaxStreams(10)
    .build();

import android.media.SoundPool;
import android.os.Bundle;
import android.view.View;
import androidx.appcompat.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity {

    private SoundPool soundPool;
    private int soundId;

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

        // 创建 SoundPool 实例
        soundPool = new SoundPool.Builder()
            .setMaxStreams(10)
            .build();

        // 加载音频文件
        soundId = soundPool.load(this, R.raw.sound_file, 1);

        // 播放音频文件
        findViewById(R.id.button).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                soundPool.play(soundId, 1, 1, 0, 0, 1);
            }
        });
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        // 释放 SoundPool 资源
        soundPool.release();
        soundPool = null;
    }
}
