1、方法一

public void onCreate(Bundle savedInstanceState) {
　　　　　
        super.onCreate(savedInstanceState);         
        setContentView(R.layout.main);

        MediaPlayer mPlayer = MediaPlayer.create(FakeCallScreen.this, R.raw.mysoundfile);
        mPlayer.start();

    }
public void onDestroy() {

    mPlayer.stop();
    super.onDestroy();

}

2、方法二：

A SoundPool is a collection of samples that can be loaded into memory from a resource inside the APK or from a file in the file system. The SoundPool library uses the MediaPlayer service to decode the audio into a raw 16-bit PCM mono or stereo stream. This allows applications to ship with compressed streams without having to suffer the CPU load and latency of decompressing during playback.

/**
 * How many sounds can be played at once.
 */
private static final int MAX_SOUND_POOL_STREAMS = 4;

/**
 * Modify this as part of your own priority scheme. Higher numbers mean higher
 * priority. If you don‘t care, it‘s okay to use the same priority for every
 * sound.
 */
private static final int NORMAL_PRIORITY = 10;

private int mySoundId;

@Override
public void setupContent() {
    this.soundPool = new SoundPool(MAX_SOUND_POOL_STREAMS,
            AudioManager.STREAM_MUSIC, 100);
    this.mySoundId = this.soundPool.load(this.getApplicationContext(),
            R.raw.mySound, 1);
}

@Override
private void playMySound() {
    this.soundPool.play(this.mySoundId, 1, 1, NORMAL_PRIORITY, 0, 1);
}
